Abstract
Leukemia is an incurable disease; it exhibits strong resistance to chemotherapy and other therapies, and it represents the most common childhood cancer and mortality. The cytotoxic of amygdalin (AMG) against the cell line of human monocytic leukemia (THP-1) was recorded, before determining other pharmacological effects. The cells were exposed to AMG for 24 hr at 37°C at different concentrations, the cytotoxic effect was determined via the MTT assay. The cells and the supernatant were collected for analyzing the oxidant/antioxidant status, apoptotic markers, and anti-microbial activity. Results showed a marked anti-proliferative cytotoxic effect of AMG which is concentration and time-dependent, the lipid peroxidation content was significantly decreased while the total thiol was increased in the treated cell line, significant up-regulation of Caspase-3 (Cas-3) and Bcl-2-associated X protein (BAX) and down-regulation of B-cell lymphoma 2 (Bcl-2). Furthermore, The bacterial activity was detected via Minimum Inhibitory Concentration (MIC), Minimum Bactericidal Concentration (MBC), and Disc Diffusion assays, while the antifungal evaluation was done by the Minimum Fungicidal Concentration (MFC). Antimicrobial experiments revealed that AMG exerted potent, broad-spectrum antimicrobial effects toward a diversity of dangerously infecting pathogens. In conclusion; the prevailing research suggests that AMG is an effective anticarcinogenic and antimicrobial substance. The utilization of AMG subsequently in masks or wound dressings to prevent bacterial & fungal infections, including mucormycosis following COVID-19, as well as infections caused by penicillium and aspergillus, is a highly effective strategy in combating resistant microorganisms.

Repro-protective activity of amygdalin and spirulina platensis in niosomes and conventional forms against aluminum chloride-induced testicular challenge in adult rats: role of CYP11A1, StAR, and HSD-3B expressions. NAUNYN-SCHMIEDEBERG'S ARCHIVES OF PHARMACOLOGY 2024; 397:3211-3226.

Abstract
The male reproductive system is negatively influenced by Al exposure. Al represented a considerable hazard to men's reproduction capabilities. Amygdalin (AMG) and spirulina platensis (SP) have been considered to have a strong antioxidant and repro-protective activity; also, targeted drug delivery systems called niosomes improve the distribution of water-soluble medications like amygdalin and spirulina. Current study targeted to determine the effectiveness of AMG and SP against negative reproductive impact resulted by aluminum chloride (AlCl3) toxicity. Sixty adult male albino rats were separated into 6 groups, including the control group, which received distilled water; AlCl3 group, which received AlCl3; AMG+AlCl3 group, which received AlCl3+AMG; AMGLN+AlCl3 group, which received AlCl3+amygdalin-loaded niosomes; SP+AlCl3 group, which received AlCl3+SP; and SPLN+AlCl3 group, which received AlCl3+spirulina-loaded niosomes. All treatments were orally gavaged daily for 5 weeks, and rats were weighed weekly. At the termination of the experiment, some males (three from each group) were used for fertility traits via mating thirty virgin rat females (in a ratio of 1:2 and 2:3 male:female, respectively) followed by recording of birth weights and litter size (number of pups per each female) at birth to assess males' reproductive capability. Other males were euthanized for collection of serum, epididymal semen samples, and tissue samples for biochemical, sperm evaluation, gene expression, and histopathological measurements. There are a considerable number of negative impacts of AlCl3 on male fertility clarified by declined serum testosterone levels; an increased oxidative stress (MDA, TAC); deteriorated semen quality; down-regulation of CYP11A1, StAR, and HSD-3b gene expressions; and testicular tissue degenerative changes. In addition, litter size (number of pups per each female) and birth weights of pups obtained from mated females were affected. AMG and SP treatments, either in niosomal or conventional form, alleviated the AlCl3 negative effects by reducing oxidative stress; increasing testosterone levels; improving semen quality; upregulating of CYP11A1, StAR, and HSD-3b gene expressions; and reducing degenerative changes of testicular tissue. Besides, negative reproductive effect was diminished as observed by changes in the litter size (number of pups per each female) and birth weights of pups obtained from mated females. AMG and SP treatments (either in niosomal or conventional form), ameliorated the AlCl3 negative effects as they possess powerful antioxidant activity, as well as they have the ability to improve the reproductive activity of affected males.

Abstract
Armeniacae semen amarum-seeds of Prunus armeniaca L. (Rosaceae) (ASA), also known as Kuxingren in Chinese, is a traditional Chinese herbal drug commonly used for lung disease and intestinal disorders. It has long been used to treat coughs and asthma, as well as to lubricate the colon and reduce constipation. ASA refers to the dried ripe seed of diverse species of Rosaceae and contains a variety of phytochemical components, including glycosides, organic acids, amino acids, flavonoids, terpenes, phytosterols, phenylpropanoids, and other components. Extensive data shows that ASA exhibits various pharmacological activities, such as anticancer activity, anti-oxidation, antimicrobial activity, anti-inflammation, protection of cardiovascular, neural, respiratory and digestive systems, antidiabetic effects, and protection of the liver and kidney, and other activities. In clinical practice, ASA can be used as a single drug or in combination with other traditional Chinese medicines, forming ASA-containing formulas, to treat various afflictions. However, it is important to consider the potential adverse reactions and pharmacokinetic properties of ASA during its clinical use. Overall, with various bioactive components, diversified pharmacological actions and potent efficacies, ASA is a promising drug that merits in-depth study on its functional mechanisms to facilitate its clinical application.

The Potential of Plum Seed Residue: Unraveling the Effect of Processing on Phytochemical Composition and Bioactive Properties. Int J Mol Sci 2024; 25:1236. [PMID: 38279238 PMCID: PMC11154296 DOI: 10.3390/ijms25021236] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/20/2023] [Revised: 01/12/2024] [Accepted: 01/17/2024] [Indexed: 01/28/2024] Open
Abstract
Bioactive compounds extracted from plum seeds were identified and quantified, aiming to establish how the brandy manufacturing process affects the properties and possible cascade valorization of seed residues. Extraction with n-hexane using Soxhlet has provided oils rich in unsaturated fatty acids (92.24-92.51%), mainly oleic acid (72-75.56%), which is characterized by its heart-healthy properties. The fat extracts also contain tocopherols with antioxidant and anti-inflammatory properties. All the ethanol-water extracts of the defatted seeds contain neochlorogenic acid (90-368 µg·g-1), chlorogenic acid (36.1-117 µg·g-1), and protocatechuate (31.8-100 µg·g-1) that have an impact on bioactive properties such as antimicrobial and antioxidant. Anti-amyloidogenic activity (25 mg·mL-1) was observed in the after both fermentation and distillation extract, which may be related to high levels of caffeic acid (64 ± 10 µg·g-1). The principal component analysis showed that all plum seed oils could have potential applications in the food industry as edible oils or in the cosmetic industry as an active ingredient in anti-aging and anti-stain cosmetics, among others. Furthermore, defatted seeds, after both fermentation and distillation, showed the greatest applicability in the food and nutraceutical industry as a food supplement or as an additive in the design of active packaging.

Abstract
Alzheimer's disease (AD) is an extremely complex, heterogeneous, and multifactorial neurodegenerative disease clinically characterized by progressive memory loss and progressive decline in cognitive function. There is currently no effective treatment for the onset and/or progression of the pathophysiological diseases of AD. The global prevalence of this disease has increased in recent years due to modern lifestyle. Therefore, there is an urgent need to develop a drug with significant neuroprotective potential. Since plant metabolites, especially polyphenols, have important pharmacological properties acting against β-amyloid (Aβ), Tau, neuroinflammation, and oxidative stress, such phytochemicals were selected in the present research. Using the Schrödinger tool (Maestro V.13.6), the drug potency of these metabolites was studied after installation in the highly configured workstation. Among the 120 polyphenols docked, amygdalin showed notable docking values of - 11.2638, followed by eriocitrin (- 10.9569), keracyanin (- 10.7086), and amaroswerin (- 9.48126). The prominent MM-GBSA values of these molecules were - 62.8829, - 52.1914, - 68.6307, and - 63.1074, respectively. The MM-GBSA energy values demonstrated the drug stability of these molecules for β-site amyloid precursor protein-cleaving enzyme 1 (BACE1)-causing AD. In the absorption and distribution assessment, these phytochemicals showed significantly better values than the inhibitors CNP520. The chosen phytochemicals have been demonstrated as non-hepatotoxic; however, the BACE1 inhibitor CNP520 is hepatotoxic. In both the molecular docking and ADMET assessments, these natural chemicals have shown optimism as potential drug candidates for Alzheimer's disease. However, in order to understand the detailed biological metabolism of these compounds in AD, they need to be evaluated in in vivo studies to validate its efficacy.

Valorization of Defatted Cherry Seed Residues from Liquor Processing by Matrix Solid-Phase Dispersion Extraction: A Sustainable Strategy for Production of Phenolic-Rich Extracts with Antioxidant Potential. Antioxidants (Basel) 2023; 12:2041. [PMID: 38136161 PMCID: PMC10741144 DOI: 10.3390/antiox12122041] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/29/2023] [Revised: 11/17/2023] [Accepted: 11/21/2023] [Indexed: 12/24/2023] Open
Abstract
The integrated valorization of food chain waste is one of the most promising alternatives in the transition to a sustainable bioeconomy. Thus, an efficient solid-phase matrix dispersion extraction method, using experimental factorial design and response surface methodology, has been developed and optimized for the recovery of polyphenols from defatted cherry seeds obtained after cherry liquor manufacture and subsequent fatty acid extraction, evaluating the effect of each processing step on the composition and phenolic content of sweet cherry residues. The phenolic extracts before fermentation showed the highest content of total polyphenols (TPC) and flavonoids (TFC) (3 ± 1 mg QE·g-1 and 1.37 ± 0.08 mg GAE·g-1, respectively), while the highest antioxidant capacity was obtained in the defatted seed extracts after both fermentation and distillation. In addition, high-performance liquid chromatography coupled to a quadrupole time-of-flight mass spectrometer (HPLC-ESI-QTOF-MS) was used to determine the phenolic profile. Dihydroxybenzoic acid, neochlorogenic acid, caffeic acid, and quercetin were the main phenolics found, showing differences in concentration between the stages of liquor production. The results underline the prospective of cherry by-products for obtaining phenol-rich bioactive extracts for possible use in different industrial sectors, offering a feasible solution for the cascade valorization of cherry agri-food waste.

Abstract
N-glycanase 1 (NGLY1) is an essential enzyme involved in the deglycosylation of misfolded glycoproteins through the endoplasmic reticulum (ER)-associated degradation (ERAD) pathway, which could hydrolyze N-glycan from N-glycoprotein or N-glycopeptide in the cytosol. Recent studies indicated that NGLY1 inhibition is a potential novel drug target for antiviral therapy. In this study, structure-based virtual analysis was applied to screen candidate NGLY1 inhibitors from 2960 natural compounds. Three natural compounds, Poliumoside, Soyasaponin Bb, and Saikosaponin B2 showed significantly inhibitory activity of NGLY1, isolated from traditional heat-clearing and detoxifying Chinese herbs. Furthermore, the core structural motif of the three NGLY1 inhibitors was a disaccharide structure with glucose and rhamnose, which might exert its action by binding to important active sites of NGLY1, such as Lys238 and Trp244. In traditional Chinese medicine, many compounds containing this disaccharide structure probably targeted NGLY1. This study unveiled the leading compound of NGLY1 inhibitors with its core structure, which could guide future drug development.

Amygdalin as a Promising Anticancer Agent: Molecular Mechanisms and Future Perspectives for the Development of New Nanoformulations for Its Delivery. Int J Mol Sci 2023; 24:14270. [PMID: 37762572 PMCID: PMC10531689 DOI: 10.3390/ijms241814270] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/15/2023] [Revised: 09/14/2023] [Accepted: 09/15/2023] [Indexed: 09/29/2023] Open
Abstract
Cancer rates are increasing, and cancer is one of the main causes of death worldwide. Amygdalin, also known as vitamin B17 (and laetrile, a synthetic compound), is a cyanogenic glycoside compound that is mainly found in the kernels and pulps of fruits. This compound has been proposed for decades as a promising naturally occurring substance which may provide anticancer effects. This is a comprehensive review which critically summarizes and scrutinizes the available studies exploring the anticancer effect of amygdalin, highlighting its potential anticancer molecular mechanisms as well as the need for a nontoxic formulation of this substance. In-depth research was performed using the most accurate scientific databases, e.g., PubMed, Cochrane, Embase, Medline, Scopus, and Web of Science, applying effective, characteristic, and relevant keywords. There are several pieces of evidence to support the idea that amygdalin can exert anticancer effects against lung, breast, prostate, colorectal, cervical, and gastrointestinal cancers. Amygdalin has been reported to induce apoptosis of cancer cells, inhibiting cancer cells' proliferation and slowing down tumor metastatic spread. However, only a few studies have been performed in in vivo animal models, while clinical studies remain even more scarce. The current evidence cannot support a recommendation of the use of nutritional supplements with amygdalin due to its cyano-moiety which exerts adverse side effects. Preliminary data have shown that the use of nanoparticles may be a promising alternative to enhance the anticancer effects of amygdalin while simultaneously reducing its adverse side effects. Amygdalin seems to be a promising naturally occurring agent against cancer disease development and progression. However, there is a strong demand for in vivo animal studies as well as human clinical studies to explore the potential prevention and/or treatment efficiency of amygdalin against cancer. Moreover, amygdalin could be used as a lead compound by effectively applying recent developments in drug discovery processes.

Int J Biol Macromol 2023; 239:124201. [PMID: 37001771 DOI: 10.1016/j.ijbiomac.2023.124201] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/03/2023] [Revised: 03/15/2023] [Accepted: 03/23/2023] [Indexed: 04/03/2023]
Abstract
In this study, PLA/PEG nanofibers (NFs) loaded with amygdalin (AMG) and bitter almond kernels extract were produced by electrospinning to prevent local breast cancer recurrence, and the effect of produced NFs on the MCF-7 cell line was investigated in vitro. The electrospun NFs were characterized by scanning electron microscopy (SEM), Fourier-transform infrared spectroscopy (FT-IR), thermal analysis (DSC) and tensile strength and physical analyzes were performed. Loading of AMG to nanofibers increased fiber diameters from 827.93 ± 174.507 nm to 1855.32 ± 291.057 μm. When drug release results were analyzed, the NFs showed a controlled release profile extending up to 10 h. The encapsulation efficiency of AMG-loaded NFs was calculated at 100 ± 0,01 %, 94 ± 0,02 %, and 88 ± 0,02 %. When in vitro cytotoxicity results were analyzed, showed that all NFs are effective in inducing cytotoxicity against MCF-7 breast cancer cells. Importantly, 20 mg AMG-loaded NFs displayed effectively higher cytotoxic effects against breast cancer cells relative to the other NFs. Considering all the results, AMG-loaded NFs can give sustained release of drugs at the local sites. Therefore, AMG-loaded nanofibers can reduce the risk of local recurrence of cancer after surgery and can be directly implanted into solid tumor cells for treatment.

On delicate balance between formation and decay of tetracyanoethylene molecular anion triggered by resonance electron attachment. J Chem Phys 2023; 158:2887211. [PMID: 37114708 DOI: 10.1063/5.0149262] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/05/2023] [Accepted: 04/12/2023] [Indexed: 04/29/2023] Open
Abstract
Low-energy (0-15 eV) resonance electron interaction with isolated tetracyanoethylene (TCNE) molecules is studied in vacuo by means of dissociative electron attachment (DEA) spectroscopy. Despite this molecule being relatively small, the long-lived molecular anions TCNE- are formed not only at thermal electron energy via a vibrational Feshbach resonance mechanism but also via shape resonances with the occupation of the π4* and π5* molecular orbitals by an incident electron. Dissociative decays of TCNE- are mostly observed at incident electron energy above the π7* temporary anion state predicted to lie at 1.69 eV by means of B3LYP/6-31G(d) calculations combined with the empirical scaling procedure. Electron attachment to the π6* orbital (predicted at 0.85 eV) leads to the generation of long-lived TCNE- species, which can decay via two competing processes: extra electron detachment, which appears in hundreds of microseconds, or elimination of two cyano groups to form the [TCNE - 2(CN)]- negative fragment on a tens of microsecond timescale. The latter is accompanied by the generation of a highly toxic cyanogen molecule as a neutral counterpart. Since the electron transfer to the acceptor molecule TCNE plays a key role in the formation of single-molecule magnets, the present data are of importance to understand the long-term behavior and likely harmful effects produced by cyanide-based prospective materials.

Abstract
Billions of tons of agro-industrial residues are produced worldwide. This is associated with the risk of pollution as well as management and economic problems. Simultaneously, non-edible portions of many crops are rich in bioactive compounds with valuable properties. For this reason, developing various methods for utilizing agro-industrial residues as a source of high-value by-products is very important. The main objective of the paper is a review of the newest studies on biologically active compounds included in non-edible parts of crops with the highest amount of waste generated annually in the world. The review also provides the newest data on the chemical and biological properties, as well as the potential application of phytochemicals from such waste. The review shows that, in 2020, there were above 6 billion tonnes of residues only from the most popular crops. The greatest amount is generated during sugar, oil, and flour production. All described residues contain valuable phytochemicals that exhibit antioxidant, antimicrobial and very often anti-cancer activity. Many studies show interesting applications, mainly in pharmaceuticals and food production, but also in agriculture and wastewater remediation, as well as metal and steel industries.

Abstract
Amygdalin is a naturally occurring glycoside used in traditional Chinese medicine and is known to have anti-cancer properties. Even though the anti-cancer properties of amygdalin are well known, its effect on normal cells has not been thoroughly investigated. The aim of the present study was to investigate a possible chemo-protective role of amygdalin against the cytotoxic effects of chemotherapy for normal human cells. Specifically, it was tested in combination with a strong chemotherapeutic drug cisplatin. Human non-tumorigenic MCF12F epithelial cell line, human fibroblasts cells, human breast cancer MCF7 and MDA-MB-231 cells were treated with cisplatin in a dose- and time-depended manner in the absence or presence of amygdalin. When MCF12F cells and fibroblasts underwent pre-treatment with amygdalin followed by cisplatin treatment (24 h amygdalin + 24 h cisplatin), the cell viability was increased (22%, p < 0.001) as indicated using MTT assay. As attested by flow cytometry, combination treatment was associated with decreased the percentage of late apoptotic cells compared with monotherapy (fold-change of decrease = 1.6 and 4.5 for 15 and 20 μΜ, respectively). Also, the proteins expression of PUMA, p53, phospho-p53 and Bax decreased, when a combination treatment was used vs. cisplatin alone, while the proapoptotic proteins Bcl-2 and Bcl-xL exhibited an increased tendency in the presence of amygdalin. Moreover, the levels of pro-apoptotic genes PUMA, p53, and BAX mRNA were significantly downregulated (∼83%, ∼66%, and ∼44%, respectively) vs. cisplatin alone, while the mRNA levels of anti-apoptotic genes BCl-2 and Bcl-XL were upregulated (∼44.5% and ∼51%, respectively), vs. cisplatin alone after 24 h of combination treatment. The study on the Combination index (CI) assay indicated that amygdalin could be possibly considered as an antagonist to cisplatin (2.2 and 2.3) for MCF12F and fibroblast cells, respectively. In contrast, for the breast cancer MCF7 and MDA-MB-231 cells, amygdalin and cisplatin indicated a synergistic effect (0.8 and 0.65), respectively. Our present findings suggest that amygdalin has chemo-modulatory effect when used in co-treatment with cisplatin and is able to protect normal breast cells as well as the fibroblasts during chemotherapy treatment, indicating a strong selective chemoprotective ability and may contribute to a better quality of life for cancer patients.

Abstract
Flaxseed consumption (Linum usitatissimum L.) has increased due to its potential health benefits, such as protection against inflammation, diabetes, cancer, and cardiovascular diseases. However, flaxseeds also contains various anti-nutritive and toxic compounds such as cyanogenic glycosides, and phytic acids etc. In this case, the long-term consumption of flaxseed may pose health risks due to these non-nutritional substances, which may be life threatening if consumed in high doses, although if appropriately utilized these may prevent/treat various diseases by preventing/inhibiting and or reversing the toxicity induced by other compounds. Therefore, it is necessary to remove or suppress the harmful and anti-nutritive effects of flaxseeds before these are utilized for large-scale as food for human consumption. Interestingly, the toxic compounds of flaxseed also undergoes biochemical detoxification in the body, transforming into less toxic or inactive forms like α-ketoglutarate cyanohydrin etc. However, such detoxification is also a challenge for the development, scalability, and real-time quantification of these bioactive substances. This review focuses on the health affecting composition of flaxseed, along with health benefits and potential toxicity of its components, detoxification methods and mechanisms with evidence supported by animal and human studies.

Abstract
Food processing sustainability, as well as waste minimization, are key concerns for the modern food industry. A significant amount of waste is generated by the fruit juice industry each year. In addition to the economic losses caused by the removal of these wastes, its impact on the environment is undeniable. Therefore, researchers have focused on recovering the bioactive components from fruit juice processing, in which a great number of phytochemicals still exist in the agro-industrial wastes, to help minimize the waste burden as well as provide new sources of bioactive compounds, which are believed to be protective agents against certain diseases such as cardiovascular diseases, cancer, and diabetes. Although these wastes contain non-negligible amounts of bioactive compounds, information on the utilization of these byproducts in functional ingredient/food production and their impact on the sensory quality of food products is still scarce. In this regard, this review summarizes the most recent literature on bioactive compounds present in the wastes of apple, citrus fruits, berries, stoned fruits, melons, and tropical fruit juices, together with their extraction techniques and valorization approaches. Besides, on the one hand, examples of different current food applications with the use of these wastes are provided. On the other hand, the challenges with respect to economic, sensory, and safety issues are also discussed.

Abstract
Abstract
Introduction
Amygdalin is a chemical compound found in the seeds of many edible plants. Different studies using cancer cell cultures in vitro indicate its potential anti-cancer activity. Various types of cancer cells showed different responses to different doses of amygdalin. This may suggest many in vitro models of the activity of this compound. The aim of the study was to evaluate the effect of amygdalin on MCF-7, MDA-MB-231, and T-47D breast cancer cells and on HFF-1 normal dermal fibroblasts (control cell culture) in vitro. Cell proliferation, viability, and the changes in mRNA transcript levels of basic proteins (BAX, caspase 3 and BCL-2) involved in apoptosis were analyzed.
Materials and Methods
MCF-7, MDA-MB-231, T-47D, and HFF-1 cell lines were purchased from the ATCC. Amygdalin derived from apricot kernels was purchased from Sigma-Aldrich. CVDE, WST-1, and LDH assays were used to evaluate the effects of amygdalin on cell proliferation and viability. Molecular evaluation of gene transcription levels was performed using the RT-qPCR technique.
Results
Amygdalin causes a dose-dependent decrease in proliferation and metabolic activity of MCF-7, MDA-MB-231, and T-47D cells in the in vitro cultures. In all cell cultures amygdalin affects the mRNA levels of pro-apoptotic BAX and caspase 3 proteins and anti-apoptotic BCL-2 protein.
Conclusions
Amygdalin anti-cancer activity may be selective in relation to different cell types. It seems that examined breast cancer cells are more sensitive to amygdalin than normal cells.

Abstract
Prunus mume Sieb. Et Zucc (P. mume) is an acidic fruit native to China (named Chinese Mei or greengage plum). It is currently cultivated in several Asian countries, including Japan ("Ume"), Korea (Maesil), and Vietnam (Mai or Mo). Due to its myriad nutritional and functional properties, it is accepted in different countries, and its characteristics account for its commercialization. In this review, we summarize the information on the bioactive compounds from the fruit of P. mume and their structure-activity relationships (SAR); the pulp has the highest enrichment of bioactive chemicals. The nutritional properties of P. mume and the numerous uses of its by-products make it a potential functional food. P. mume extracts exhibit antioxidant, anticancer, antimicrobial, and anti-hyperuricaemic properties, cardiovascular protective effects, and hormone regulatory properties in various in vitro and in vivo assays. SAR shows that the water solubility, molecular weight, and chemical conformation of P. mume extracts are closely related to their biological activity. However, further studies are needed to evaluate the fruit's potential nutritional and functional therapeutic mechanisms. The industrial process of large-scale production of P. mume and its extracts as functional foods or nutraceuticals needs to be further optimized.

Abstract
AIM Hepatocellular carcinoma (HCC) is a potentially life-threatening cancer. In the current study, anti-HCC efficacy of amygdalin, or metformin alone or in combination in comparison to doxorubicin was studied. MAIN METHODS Both in-vitro and in-vivo based models. HepG-2 and Huh-7 cell lines as established in-vitro model for HCC were treated with different concentrations of indicated drugs to evaluate the cytotoxicity and determine IC50 for 24, 48 and 72 h. Moreover, the effect of different treatments on apoptosis and cell cycle using flow cytometric analysis were studied. Hepatocellular carcinoma induced in rats by diethyl-nitrosamine and carbon tetrachloride was established, to further investigate the efficacy of indicated drugs. Aspartate aminotransferase, alanine aminotransferase and alkaline phosphatase were measured by spectrophotometer, alpha-fetoprotein, cytochrome-c, caspase-3 and malondialdehyde were measured by ELISA, and liver biopsies were also evaluated histopathologically. KEY FINDINGS In-vitro results showed that the combination has a promising effect when compared to amygdalin or metformin alone as it is more cytotoxic and have higher ability for induction of apoptosis and arresting cell cycle. In-vivo doxorubicin has a good effect for treating HCC. Also, the combination showed a promising prognostic effect depending on the cytotoxic activity and tumor marker when compared to amygdalin or metformin alone. SIGNIFICANCE Based on the current data, it was hypothesized that amygdalin and metformin especially when used in combination will be a promising approach with low side effects for enhancement of HCC.

Abstract
The present review summarizes the current knowledge on the provenance and properties, metabolism and toxicity, mechanism of action, physiological, and therapeutic roles of amygdalin-a molecule present in the seeds of apricot and other plants-with an emphasis on the action of amygdalin on reproductive processes, particularly in the female. Amygdalin influences physiological processes including female reproduction at various regulatory levels via extra- and intracellular signaling pathways regulating secretory activity, cell viability, steroidogenesis, proliferation, and apoptosis. On the other hand, while being metabolized in the body, amygdalin releases significant amounts of cyanide, which may lead to acute health hazard in those individuals who may be at risk. Despite some contradictions in the available data about benefits and toxic effects of amygdalin, its potential applicability at low doses may present a promising tool for regulation of various reproductive and other physiological processes including disease management primarily in cancer phytotherapy, animal production, medicine, and biotechnology. However, further research involving carefully designed dose-response studies is required to overcome the possible side effects of amygdalin and assure its safety as a therapeutic agent.

Abstract
Background and Objectives The relationship between vascular damage and diabetes mellitus was exploited using avocado seed extracts. The purpose of the study was to understand the therapeutic relevance of glycosides compared to standard vascular and anti-diabetic drugs. Constituent Avocado Seed Glycosides (ASG) were analysed and administered to rats with Diabetes-Induced Vascular Damage (DIVD). Methods The rats were first administered with streptozotocin and screened after seven days for alterations in blood glucose, insulin, vascular cell adhesion molecule (VCAM-1), Von Willebrand factor (VWF), Renin-Angiotensin-Aldosterone System (RAS), eNOx, and endothelin-1 (ET-1). Only rats that satisfied these criteria were recruited and treated with either glibenclamide, met.su + losart, or 200 mg/kg body weight ASG for 28 days. Results There was an abundance of digitoxin (13.41 mg/100g), digoxin (17.98 mg/100g), avicularin (165.85 mg/100g), and hyperoside (282.51 mg/100g). ASG or met.su + losart exhibited slight modulatory properties on glucose homeostasis. Rats with DIVD showed elevated renin, angiotensin, VCAM-1 and Lp-PLA2 levels but slightly decreased with glibenclamide treatment and normalized with ASG or met.su + losart administration. All treatments normalized Hcy levels. DIVD caused the overproduction of CnT, LDH, Crt-K, LDL-c, TG, and TC and suppressed HDL-c but was completely normalized by the ASG. Water intake remained altered in treated rats. Conclusion The ASG had no relevant effect on glucose homeostasis during DIVD but showed significant vasoprotective properties.

Abstract
Amygdalin has been promoted as an alternative cancer cure. However, it is still unclear how this cyanogenic glycoside affects non-cancer cells including bone cells. This study first investigated the impact of amygdalin on viability, morphology and expression of important genes in human osteoblasts in vitro. Primary human osteoblast cultures were exposed to amygdalin at concentrations 0; 0.1; 1 and 10 mg/mL in growth medium for 72 h. Cell viability, osteoblasts morphology and expression of 10 genes associated with osteoblast-specific pathways, oxidative stress and cell death were determined. Osteoblasts viability was significantly decreased (-27.26%) and their size was reduced (-23.20%) at the highest concentration of amygdalin (10 mg/mL). This concentration of amygdalin down-regulated the expression of COL1A1 and ALPL genes, whereas the expression of BGLAP, TNFSF11 and WNT5A genes was increased. The osteoblast cultivation with 0.1 mg/mL amygdalin caused down-regulation of COL1A1 gene. No changes in expression were determined for RUNX2, BAX, CASP1, SOD1 and GPX1 genes among all tested concentrations of amygdalin. In conclusion, amygdalin in a high concentration negatively affected mineralization of extracellular matrix, increased bone resorption and decreased osteoblast viability. These changes were accompanied by modified expression profiles of responsible genes.

Abstract
Cancer is a major health issue concerning to all of us. Current treatment options are still limited due to not-selective action. Encapsulation is contemplated as an innovative approach to address systemic toxicity and tumor resistance caused by traditional therapies, while increasing encapsulated compounds bioavailability. The coating material of capsules strongly determines the success of the system. Since alginate has been proved non-toxic, biocompatible and biodegradable, it is considered a potential vehicle for therapeutic factors encapsulation. Besides, it has the particular ability to form hydrogels, which hold a high-water content and greatly resemble to natural soft tissues. The present review exposes the state-of-the-art and the most sophisticated alginate-based systems for cancer therapy and research. It begins with an overview of alginate hydrogels and the qualities that make them especially suitable for biomedical applications. In the following section, the application of alginate hydrogels as pioneering strategies for cancer treatment is described. Several examples of alginate-based delivery systems of therapeutic drugs, proteins and nucleic acids are provided. Significant emphasis is placed in both oral delivery systems and colorectal cancer therapy. Moreover, the role of alginate 3-D scaffolds for both cell culture and delivery is explained. Lastly, other applications of alginate-based hydrogels such as tumor biomarkers immunosensing and fluorescent surgical marker are included.

Abstract
Background — Radiation and chemotherapy of cancer cause complications that drastically reduce the quality of life. This requires the search for effective therapeutic agents for the mucositis treatment. We investigated the effects of amygdalin as a trophic external agent for post-radiation and post-chemotherapeutic oral mucositides. The study objectives were to conduct an immunomorphological analysis using an experimental model of iatrogenic mucositis, and to evaluate the effectiveness of amygdalin as cyanide with probable protective chemical properties in mucositis correction. Material and Methods — Our studies were performed on 40 male white rats. Radiation therapy was simulated by irradiating animals with a cranial dose of 6 Gy. Then an intraperitoneal injection of cisplatin was performed. On day 7, a biopsy was taken (model control), and animals were treated for 14 days with a mixture of 0.02% nitrofurazone, Desensitin® gel, Suprasorb® and amygdalin, after which a biopsy was taken again (therapy control). Results — Immunomorphological studies revealed dystrophic structural changes due to the progress of tissue hypoxia and the launch of Fas-dependent apoptosis in tissues. Using treatment with amygdalin by activating hypoxia-inducible factor (HIF) stimulates the macrophage population to remodel the stroma of the submucosal layer. In addition to activating the cellular components of local immunity, a therapeutic anti-apoptotic effect has been established. Conclusion — The method of mucositis correction by amygdalin is effective, which is confirmed by increased proliferation and decreased apoptosis due to revascularization and hypoxia reduction.

Abstract
Traditional Chinese medicines (TCMs) are medicines that are widely used in oriental countries under the guidance of ancient Chinese medicinal philosophies. With thousands of years of experiences in fighting against diseases, TCMs are gaining increasing importance in the world. Although the efficacy of TCMs is well recognized in clinic, the toxicity of TCMs has become a serious issue around the world in recent years. In general, the toxicity of TCMs is caused by the toxic medicinal compounds and contaminants in TCMs such as pesticides, herbicides, and heavy metals. Recent studies have demonstrated that gut microbiota can interact with TCMs and thus influence the toxicity of TCMs. However, there is no focused review on gut microbiota and the toxicity of TCMs. Here, we summarized the influences of the gut microbiota on the toxicity of medicinal compounds in TCMs and the corresponding mechanisms were offered. Then, we discussed the relationships between gut microbiota and the TCM contaminants. In addition, we discussed the methods of manipulating gut microbiota to reduce the toxicity of TCMs. At the end of this review, the perspectives on gut microbiota and the toxicity of TCMs were also discussed.

Abstract
The equilibrium solubility of amygdalin in [ethanol (1) + water (2)] mixtures at 293.15 K to 328.15 K was reported. The thermodynamic properties (standard enthalpy ΔsolnH°, standard entropy ΔsolnS°, and standard Gibbs energy of solution ΔsolnG°) were computed using the generated solubility data via van't Hoff and Gibbs equations. The dissolution process of amygdalin is endothermic and the driving mechanism in all mixtures is entropy. Maximal solubility was achieved in 0.4 mole fraction of ethanol at 328.15 K and the minimal one in neat ethanol at 293.15 K. Van't Hoff, Jouyban-Acree-van't Hoff, and Buchowski-Ksiazczak models were used to simulate the obtained solubility data. The calculated solubilities deviate reasonably from experimental data. Preferential solvation parameters of amygdalin in mixture solvents were analyzed using the inverse Kirkwood-Buff integrals (IKBI) method. Amygdalin is preferentially solvated by water in ethanol-rich mixtures, whereas in water-rich mixtures, there is no clear evidence that determines which of water or ethanol solvents would be most likely to solvate the molecule.

Abstract
Amygdalin is a natural cyanogenic compound that plants produce in the fight against insects and herbivores. Excessive amounts of amygdalin by animals and humans can potentially lead to fatal intoxication. However, studies confirm that amygdalin has antitumor properties, including the ability to inhibit the proliferation of cancer cells and to induce their apoptosis. The analysis of amygdalin in various matrices is an important analytical problem today. The publication presents the methodology of direct determination of amygdalin in water, sewage, and biological materials using electrospray ionization mass spectrometry (ESI-MS) and a new analytical method using flowing atmospheric-pressure afterglow mass spectrometry (FAPA-MS). The methods of analyte pre-concentration using a magnetic, molecularly imprinted polymer (mag-MIP) and the influence of interferents on the recorded spectra were discussed. Analytical parameters in ESI-MS and FAPA-MS methods were established. The linearity range was 4.5 µg L−1–45 mg L−1 in positive mode ESI-MS and FAPA-MS. The limit of detection (LOD) for ESI-MS was 0.101 ± 0.003 µg L−1 and the limit of quantification (LOQ) was 0.303 ± 0.009 µg L−1. In FAPA-MS, the LOD was 0.050 ± 0.002 µg L−1 and the LOQ was 0.150 ± 0.006 µg L−1. The content of amygdalin in various matrices was determined.

Abstract
BACKGROUND AND OBJECTIVE Historically, amygdalin has been used as alternative medicine or in vitro and in vivo studies, but no single study exists which discusses the structural mechanism of amygdalin at a molecular level. This paper inquiries into the inhibitory actions of amygdalin on the selected targets: AKT1, FAK, and ILK, which are regulators for various mediated signaling pathways, and are associated with cell adhesion, migration, and differentiation. In order to get details at the molecular level of amygdalin's inhibitory activities against chosen proteins, molecular modeling and simulation techniques including double docking, molecular dynamics simulation, free energy landscape analysis, and binding free energy calculation were exerted. METHODS To get molecular level details of amygdalin inhibitory effects against the relevant proteins; here the utilized tools are the following: the double docking, molecular dynamics simulation, free energy landscape analysis, g_mmpbsa, and interaction entropy were used to evaluate the inhibitory activity against targeted proteins. RESULTS The computational calculations revealed that amygdalin inhibits the selected targets via block the ATP-binding pocket of AKT1, FAK, and ILK by forming stable hydrogen bonds. Moreover, free energy landscape, FEL exposed that amygdalin stabilized the global conformations of both FAK and ILK proteins to the minimum global energy besides it reduced the essential dynamics of FAK and ILK proteins. MMPBSA computations provided further evidence for amygdalin's stability inside the ATP-binding pocket of AKT1, FAK, and ILK with a binding free energy of 45.067, -13.033, 13.109 kJ/mol, respectively. The binding free energies are lastly consistent with the hydrogen bonding and pairs within 0.35 nm results. The decomposition of binding energy shows the pivotal amino acid residues responsible for the stability of amygdalin's interactions inside the ATP-binding sites by forming hydrogen bonds. CONCLUSIONS Before this work, it was enigmatic to make predictions about how amygdalin inhibits metastasis of cancer. But the computational results contribute in several ways to our understanding of amygdalin activity and provide a basic insight into the activity of amygdalin as a multi-target drug in the metastasis and invasion of cancer.

Abstract
Amygdalin is a cyanogenic glycoside, mainly present in the seeds of the Rosaceae family such as apricots, peaches, and bitter almond. In this study, in vitro genotoxic and antigenotoxic effects of amygdalin have been investigated on human peripheral blood lymphocytes using the comet assay. The antigenotoxic effect of amygdalin was performed against hydrogen peroxide (H2O2) using three different treatment types (pre-, simultaneous, and post-treatment). The isolated lymphocytes were incubated with different concentrations of amygdalin (0.86-13.75 µg/ml) alone and in combination with H2O2 (100 µM). The results indicated that amygdalin exhibited an antigenotoxic effect against H2O2, but it did not induce the genotoxic effect alone in tested concentrations in vitro on human lymphocytes. PRACTICAL APPLICATIONS: Amygdalin is a natural compound used in alternative medicine as an anti-cancer, antipyretic, and cough suppressant. The comet assay which is relatively simple, rapid, sensitive, and economically efficient, measures the changes in genomic stability. Assessment of amygdalin alone has no genotoxic effect on human lymphocytes. Moreover, antigenotoxicity applications (pre-, simultaneous, and post-treatments) of amygdalin significantly reduced the DNA damage induced by H2O2 on isolated human lymphocytes. In conclusion, amygdalin is not genotoxic, also, it exhibited antigenotoxic activity against oxidatively damaged DNA due to its antioxidant properties on human lymphocytes.

Abstract
Amygdalin induces apoptotic death in several carcinoma cells. Affibody is an engineered protein with a high affinity for human epidermal receptor 2 (HER2). We assessed the cytotoxic effects of the amygdalin-ZHER2 affibody conjugate on two breast carcinoma cell lines. The ZHER2 affibody gene was synthesized and transferred into E. coli BL21 as an expression host. After purification, the ZHER2 affibody was conjugated to amygdalin. The cytotoxic effects of amygdalin and its ZHER2 affibody conjugate on the SK-BR-3, with overexpression of HER2, and MCF-7 cells were evaluated by MTT assay. The effects of amygdalin and its conjugate on apoptotic death and expression of pro-apoptotic Bax and anti-apoptotic Bcl-2 proteins were measured. Amygdalin individually showed a potent cytotoxic effect against both MCF-7 (IC50 = 14.2 mg ml-1) and SK-BR-3 cells (IC50 = 13.7 mg ml-1). However, the amygdalin-ZHER2 affibody conjugate had a more cytotoxic effect on SK-BR-3 (IC50 = 8.27 mg ml-1) than MCF-7 cells (IC50 = 19.8 mg ml-1). Amygdalin had a significant apoptotic effect on both cell lines and the effect of its conjugate on SK-BR-3 cells was significantly more potent than MCF-7 cells. Amygdalin increased Bax and decreased Bcl-2 expression in both cell lines. However, the effect of its conjugate on the Bax and Bcl-2 expression in SK-BR-3 was more potent than MCF-7 cells. In conclusion, the amygdalin-ZHER2 affibody conjugate may be considered as a valuable candidate for specific treatment of breast cancer patients with overexpression of HER2. However, further in vivo studies are required to explain the antitumoral effects of constructed amygdalin-ZHER2 affibody conjugate.

Abstract
Amygdalin a naturally occurring compound, predominantly in the bitter kernels of apricot, almond, apple and other members of Rosaceae family. Though, amygdalin is used as an alternative therapy to treat various types of cancer but its role in cancer pathways has rarely been explored yet. Therefore, present study was intended with the aim to investigate the alleged anti-cancerous effects of amygdalin specifically on PI3K-AKT-mTOR and Ras pathways of cancer in human body. Computational modelling and simulation techniques were used to assess the effect of amygdalin on PI3K-AKT-mTOR and Ras pathways using different level of dosage. It was observed that amygdalin had direct and substantial contribution to regulate PI3K-mTOR activities on threshold levels while the other caner pathways were effected indirectly. Consequently, amygdalin is a down-regulator of a cancer within a specified amount and contribute considerably to reduce various types of cancer in human. Furthermore, in-vitro and in-vivo analyses of amygdalin could be of helpful to authenticate its pharmacological effects.

Abstract
Background β-Glucosidase (β-Glu) can activate amygdalin to kill prostate cancer cells, but the poor specificity of this killing effect may cause severe general toxicity in vivo, limiting the practical clinical application of this approach. Materials and Methods In this study, starch-coated magnetic nanoparticles (MNPs) were successively conjugated with β-Glu and polyethylene glycol (PEG) by chemical coupling methods. Cell experiments were used to confirm the effects of immobilized β-Glu on amygdalin-mediated prostate cancer cell death in vitro. Subcutaneous xenograft models were used to carry out the targeting experiment and magnetically directed enzyme/prodrug therapy (MDEPT) experiment in vivo. Results Immobilized β-Glu activated amygdalin-mediated prostate cancer cell death. Tumor-targeting studies showed that PEG modification increased the accumulation of β-Glu-loaded nanoparticles in targeted tumor tissue subjected to an external magnetic field and decreased the accumulation of the nanoparticles in the liver and spleen. Based on an enzyme activity of up to 134.89 ± 14.18mU/g tissue in the targeted tumor tissue, PEG-β-Glu-MNP/amygdalin combination therapy achieved targeted activation of amygdalin and tumor growth inhibition in C57BL/6 mice bearing RM1 xenografts. Safety evaluations showed that this strategy had some impact on liver and heart function but did not cause obvious organ damage. Conclusion All findings indicate that this magnetically directed enzyme/prodrug therapy strategy has the potential to become a promising new approach for targeted therapy of prostate cancer.

Abstract
BACKGROUND Little is known regarding the toxic and therapeutic doses of amygdalin. Treatment regimens and schedules can vary between humans and animal models, and there have been reports of cyanide toxicity due to amygdalin use. OBJECTIVE The aim of this study was to evaluate the effect of different doses of amygdalin on antioxidant gene expression and suppression of oxidative damage in mice. METHODS Forty adult male mice were divided randomly into four groups (n = 10) as follows and treated orally for two weeks: a control group treated with saline solution, a group treated with amygdalin at 200 mg/kg body weight, a group treated with amygdalin at 100 mg/kg body weight, and a group treated with amygdalin at 50 mg/kg body weight. Liver and testis samples were collected for gene expression, biochemical and histopathological analyses. RESULTS The mice treated with medium-dose amygdalin (100 mg/kg) showed upregulated mRNA expression of glutathione peroxidase (P < 0.01) and superoxide dismutase (P < 0.05) and significantly decreased lipid peroxidation (P < 0.05) in hepatic and testicular tissues compared to those in the untreated groups (controls), with mild histopathological effects. The mice treated with high-dose of amygdalin (200 mg/kg) showed downregulated mRNA expression of glutathione peroxidase and superoxide dismutase (P < 0.01) and significantly increased lipid peroxidation (P < 0.05) in both hepatic and testicular tissues compared to those in the untreated groups (controls), with an apparent effect at the histopathological level. No effects were observed in the mice treated with low-dose amygdalin (50 mg/kg) at the gene, protein and histopathological level. CONCLUSION Low-and medium-dose amygdalin did not induce toxicity in the hepatic and testicular tissues of male mice, unlike high-dose amygdalin, which had a negative effect on oxidative balance in mice. Therefore, amygdalin at a moderate dose may improve oxidative balance in mice.

Abstract
Cancer is the major cause of death and many factors that lead to its occurrences, such as environmental pollution and pesticides and other factors. Ehrlich carcinoma development depends on many things associated with the environment, nutrition, personal habits, and family history. The present study aimed to evaluate the potential protective effects of vitamin B17 (VB17) against Ehrlich ascites carcinoma (EAC) that induced kidney toxicity in female mice. The mice were divided into five groups (first group, control group; second group, VB17 group; third group, EAC group; fourth group, pretreated EAC with VB17; fifth group, cotreated EAC with VB17). Results showed the VB17 in pretreated (G4) and cotreated (G5) groups lead to an improvement in DNA damage and cytological examination, in addition significantly (P < .05) increase in Na+ , red blood cell, hemoglobin, hematocrit value, mean corpuscular hemoglobin (MCH), and MCH concentration, whereas significantly (P < .05) decrease in urea, creatinine, K+ , platelets, and white blood cells while insignificant (P < .05) changes in mean corpuscular volume when compared to the EAC group. Many histopathological changes were observed in kidney sections in EAC as marked damage and degenerated, glomerular atrophy, the Malpighian corpuscles that lost their characteristic configuration. On the other hand, a moderate improvement and arrangement in the kidney histological structure in pretreated VB17 + EAC, while a mild enhancement and arrangement of the kidney structure in cotreated EAC + VB17. In addition, depletion in renal P53 and PCNA protein expression compared with the EAC group. It could be concluded that VB17 has a potential renal protective effect against EAC cells induced kidney injury.

Abstract
Amygdalin possesses anticancer properties and induces apoptosis. Based on experimental studies the presence of amygdalin with cancer cells led to activate the caspase-3 and BAX and inhibits Bcl-2 and Poly (ADP-ribose) polymerase-1 (PARP-1) but without deep information on action mode of these activities. Herein, we leaped forward to examine the molecular dynamics of the bound amygdalin and free ligand proteins, to identify precise action (conformation changes in targeted proteins) of amygdalin through using double docking and molecular dynamics (MD) simulations for 50 ns time scale. The MD simulations revealed that the binding of amygdalin led to disrupting the interaction between the Bcl-2/BAX complex. We furthermore conducted MD simulation for Bcl-2/amygdalin to investigate the stability of the complex which is responsible for inhibition of Bcl-2. It has been obtained a stable Bcl-2/amygdalin complex during the 50 ns. The results give a detail explanation of how amygdalin activates BAX and inhibits Bcl-2. For caspase-3, the matter is different, we found that amygdalin led to disrupting the interaction of caspase-3's two chains for intervals during 50 ns and then bind together repeatedly. The mechanism of caspase-3's activation through switching by disrupt the interacts for periodic intervals manner. For PARP-1, the dynamics simulations results indicated amygdalin interacts with PARP-1's binding site and forms stable interaction during simulation to render it inactive. Hence, amygdalin revealed a supernatural behavior through the MD simulations: it revealed a further clarification of the mystery amygdalin's experimental action which can act as a multifunctional drug in the cancer therapeutics.Communicated by Ramaswamy H.

Abstract
Vitamin B17 (VB17), also known as amygdalin and laetrile, is a type of carbohydrate occurring naturally in many plants, such as apricot kernels which have obtained a great interest in cancer therapy. This study aimed to investigate the hepatic protective potential of VB17 against Ehrlich ascites carcinoma (EAC)-bearing mice-induced liver injury, DNA damage, apoptotic P53, and PCNA alterations. A total of 100 female mice were divided into 5 groups (1st group, control group; 2nd group, VB17 group; 3rd group, EAC group; 4th group, pre-treated EAC with VB17; 5th group, co-treated EAC with VB17). Results showed that the presence of VB17 in pre-treated and co-treated groups lead to decreased DNA damage, microsomal protein, NADPH cytochrome c reductase, alpha-fetoprotein (AFP), AST, ALT, and ALP while showed increased cytochrome b5, cytochrome P450 amidopyrine N-demethylase, and aniline 4-hydroxylase compared with the EAC group. Many histopathological changes were observed in liver sections in EAC as moderate fibrosis and marked diffuse necrosis of hepatic tissue, marked inflammatory cells, and congested blood sinusoids. On the other hand, there was a moderate degree of improvement in hepatocytes in liver sections in pre-treated VB17+EAC, while a mild degree of improvement in hepatocytes, moderate cellular infiltrations, and moderate cytoplasmic vacuolization of hepatocytes in liver sections in co-treated EAC+VB17. In addition, there was a depletion in hepatic P53 and PCNA protein expression compared with the EAC group. It could be concluded that VB17 has a potential hepatoprotective effect against EAC cell-induced liver toxicity.

Abstract
BACKGROUND Amygdalin (Vitamin B-17) is a naturally occurring vitamin found in the seeds of the fruits of Prunus Rosacea family including apricot, bitter almond, cherry, and peach. OBJECTIVE The purpose of this study was to examine the effect of amygdalin with and without zinc on hepatocellular carcinoma (HepG2) cell line. METHODS MTT assay was used to evaluate the cytotoxicity of amygdalin without zinc, amygdalin + 20μmol zinc, and amygdalin + 800μmol zinc on HepG2 cell lines. The cell cycle distribution assay was determined by flow cytometry. Apoptosis was confirmed by Annexin V-FITC/PI staining assay. Moreover, the pathway of apoptosis was determined by the percentage of change in the mean levels of P53, Bcl2, Bax, cytochrome c, and caspase-3. RESULTS Amygdalin without zinc showed strong anti-HepG2 activity. Furthermore, HepG2 cell lines treatment with amygdalin + 20μmol zinc and amygdalin + 800μmol zinc showed a highly significant apoptotic effect than the effect of amygdalin without zinc. Amygdalin treatment induced cell cycle arrest at G2/M and increased the levels of P53, Bax, cytochrome c, and caspase-3 significantly, while it decreased the level of anti-apoptotic Bcl2. CONCLUSION Amygdalin is a natural anti-cancer agent, which can be used for the treatment of hepatocellular carcinoma. It promotes apoptosis via the intrinsic cell death pathway (the mitochondria-initiated pathway) and cell cycle arrest at G/M. The potency of amygdalin in HepG2 treatment increased significantly by the addition of zinc.

Abstract
Phytochemical composition, in vitro antioxidant and antiproliferative activity against HepG2 cells were studied in the kernels of apricot cultivars grown in the northern areas of Pakistan. Relatively, the kernel of Habbi cultivar/AP-12 depicted significant potential to scavenge DPPH and ABTS+ free radicals as well as oxygen radical absorbance capacity along with highest contents of total flavonoids, phenolics, chlorogenic and syringic acids on dry weight basis. The average concentration of quercetin ranged 0.072-1.343 mg/100 g, and of EGCG from 0.713 to 6.521 mg/100 g with maximum concentration in Hulappa/AP-3 and Kho Chali-Khatta 3/AP-17, respectively. Amygdalin content was highest (1145 mg/100 g) in the kernel of Balaani/AP-14. Highest inhibition of HepG2 cells was found in the kernel of Waflu Chuli/AP-9 (EC50 = 15.70 ± 3.77 mg/mL). The PCA showed significant contributions of polyphenols and flavonoids towards biochemical assays, while CA revealed similarities and associations among various cultivars. Our study revealed that Habbi, Waflu Chuli, Thukdeena and Balaani kernels are rich sources of bioactive compounds and possess significant antioxidant and anticancer activity and can contribute considerably in the prevention and treatment of chronic health disorders.

Abstract
This study was aimed to evaluate the anti-inflammatory potential of AG on lipopolysaccharide (LPS) -induced liver injury and investigate the underlying mechanism. Administration of LPSs in the rat produced rat liver injury model which was ascertained at histological and molecular levels. Those models were treated with a range of doses of LPSs (0.5, 1.0 and 1.5 mg/kg body weight), followed by measurement physical parameter and function of the liver. Within the max treatment doses, no toxicity was shown but protective effects of AG were evidenced by regulation of physical parameters and functions of the liver. Interestingly, nuclear factor kappa B (NF-κB) levels and inflammatory factors were down-regulated by AG. Furthermore, the histopathological analysis demonstrated that AG promoted recovery from dysfunction of liver tissue in the rats, which was further confirmed by observing expression changes of inflammation-associated proteins. Particularly, alteration in the PI3K/AKT and JAK2/STAT3 signalling pathway protein expression were regulated by AG in a dose-dependent manner, indicating the mechanism underlying the relief effect of AG in liver injury. Our study demonstrated the potential of AG in the management of complications related to liver injury.

Abstract
BACKGROUND This case series describes the survival outcomes of patients who underwent integrative medicine (IM) protocol for ovarian cancer, a treatment protocol, that integrated a carefully selected set of complementary and alternative medicine (CAM) into the conventional treatment for ovarian cancers. MATERIALS AND METHODS Retrospective review of patients' medical records was conducted at a private medical centre that delivered the IM protocol for patients with advanced and recurrent ovarian cancers. We explored and analysed the overall survival and disease progressions of those who received the IM treatment for at least 2 months. RESULTS Forty patients with advanced ovarian cancers fulfilled the inclusion criteria for this case series. An overall of 75% of the cases achieved remission with initial IM treatment, 17.5% had a partial response and 7.5% showed progressive disease. The overall 5-year survival for all 40 cases is 53.1%. When explored further, the 5-year survival for cases who received CAM only is 75%, and cases who received combined limited chemotherapy with CAM had a 5-year survival of 55%. At study endpoint, 11 cases died due to ovarian cancer. CONCLUSION These findings suggest that CAM may be a valuable addition to conventional therapy to treat and improve the survival of patients with ovarian cancers. A formal randomized control trial is required to evaluate the efficacy and long-term outcomes of using IM to treat advanced and recurrent ovarian cancers.

Abstract
This work is focused on separation and determination of amygdalin and its unnatural form neoamygdalin in natural food supplements. Reversed-phase high-performance liquid chromatography with a high-stability silica-based column with C18 functional group has been used for solving this problem. The effect of the mobile phase composition as well as the column temperature on the separation of the amygdalin epimers has been investigated. Isocratic elution using a mobile phase composed of 0.05% aqueous formic acid and acetonitrile achieved the required separation within 17 min. Under optimum chromatographic conditions, the developed method was validated and was applied for the determination of amygdalin epimers in natural food supplements containing apricot or peach kernels. A simple extraction method using methanol as an extractant supported by an ultrasonic bath was used with recovery in the range of 94.8% to 104.3%. The limit of detection and limit of quantification values for R-amygdalin were 0.13 mg/L and 0.40 mg/L, respectively. The developed method proved to be precise with the intra-day and inter-day relative standard deviation values less than 2.23%.

Abstract
The overall incidence of cancer is increasing in recent years. Despite advances in various comprehensive treatments, the mortality of advanced malignant tumors remains at a high level. Numerous pharmacological studies have confirmed that many Chinese herbal medicines possess remarkable antitumor activities. Amygdalin, mainly existing in bitter almond, is reported to have antitumor properties in addition to the antioxidative, antibacterial, anti‐inflammatory and immunoregulatory activities. This article summarizes the structural characteristics of amygdalin, its antitumor mechanisms, and recent progress and achievement in the research of amygdalin, hoping that it could provide theoretical clues for exploring the clinical value of amygdalin against tumors. Amygdalin is known to have an antitumor effect in solid tumors such as lung cancer, bladder cancer and renal cell carcinoma by affecting cell cycle, inducing apoptosis and cytotoxicity, and regulating immune function. Further research is needed to elucidate the pharmacological mechanisms of amygdalin in terms of the optimal dosage, the feasibility of combined use of amygdalin with other antitumor drugs, and even artificial synthesis of the active components in amygdalin, for the sake of enhancing its antitumor activities and reducing its adverse effects for clinical use.

Abstract
Derived from rosaceous plant seed, amygdalin belongs to aromatic cyanogenic glycoside group, and its anticancer effects have been supported by mounting evidence. In this study, we objected to investigate amygdalin effect on two antiapoptotic genes (Survivin, XIAP) and two lncRNAs (GAS5, MALAT1) in human cancer cells (A549, MCF7, AGS). Employing RT-qPCR analysis, we compared the mRNA levels of the genes related to apoptosis in A549, MCF7, and AGS cancer cells between amygdalin-treated (24, 48 and 72 h) and un-treated groups. RNA was extracted from both cell groups and then cDNAs were synthesized. The changes in the gene expression levels were specified using ΔΔCt method. RT-qPCR analysis has revealed that the expression of Survivin, XIAP, GAS5 and MALAT1 in amygdala-treated cancer cells were significantly different, compared to the un-treated cells. However, these expressions were different depending on the treatment time. According to the results, amygdalin significantly inhibited the expression level of Survivin, and XIAP genes in treated via untreated group. Our findings suggest that amygdalin might have an anticancer effect due to the various gene expressions in A549, MCF7, and AGS human cancer cells, showing it's potential as a natural therapeutic anticancer drug.

Abstract
In this article, a new approach to directly synthesize drug molecule imbedded in the nanometer sized polymer particles is reported. Molecular imprinting is used to prepare polymers for drug specific for selectively loading of a desired drug. Computer simulations were performed to provide mechanistic insights on the binding modalities of model cancer drug, amygdalin with the polymer precursors. Controlled release of amygdalin from nanoMIPs was studied in vitro cell test and monitoring the absorbance at λem of 390 nm by fluorescence. The nanoparticles imprinted with amygdalin (nanoMIPs) showed high drug loading (0.98 mg g-1) and also releases drug in a controlled way without burst release. The polymer releases amygdalin 0.095 μg (5 min), 0.120 μg (30 min), 0.180 μg (180 min), 0.205 μg in 300 min in de-ionized water and similar pattern of release was observed in buffer 2 and 7. The sustained release of drug from nanoMIPs follows Fickian diffusion; and uniformity in nanoMIPs size have significant impact on release of drug. Swelling of nanoMIP is one of the dominant factors influencing the drug release patterns. The imprinting procedure and the studies reported in this study would be highly useful in future for cancer drug administration.

Abstract
Conventional and Alternative Medicine (CAM) is popularly used due to side-effects and failure of approved methods, for diseases like Epilepsy and Cancer. Amygdalin, a cyanogenic diglycoside is commonly administered for cancer with other CAM therapies like vitamins and seeds of fruits like apricots and bitter almonds, due to its ability to hydrolyse to hydrogen cyanide (HCN), benzaldehyde and glucose. Over the years, several cases of cyanide toxicity on ingestion have been documented. In-vitro and in-vivo studies using various doses and modes of administration, like IV administration studies that showed no HCN formation, point to the role played by the gut microbiota for the commonly seen poisoning on consumption. The anaerobic Bacteriodetes phylum found in the gut has a high β-glucosidase activity needed for amygdalin hydrolysis to HCN. However, there are certain conditions under which these HCN levels rise to cause toxicity. Case studies have shown toxicity on ingestion of variable doses of amygdalin and no HCN side-effects on consumption of high doses. This review shows how factors like probiotic and prebiotic consumption, other CAM therapies, obesity, diet, age and the like, that alter gut consortium, are responsible for the varying conditions under which toxicity occurs and can be further studied to set-up conditions for safe oral doses. It also indicates ways to delay or quickly treat cyanide toxicity due to oral administration and, reviews conflicts on amygdalin's anti-cancer abilities, dose levels, mode of administration and pharmacokinetics that have hindered its official acceptance at a therapeutic level.
