Abstract
Zanthoxylum rhetsa (ZR) is used traditionally to manage a variety of ailments, including diabetes. Oxidative stress may accelerate the diabetic condition. The available antidiabetic and antioxidant drugs have many shortcomings including resistance, inefficiency, higher dose, side effects and costs. The goal of the current investigation was to assess the antioxidant capacity and antidiabetic activity of an ethanolic extract of Zanthoxylum rhetsa root bark (ZRRB) through in vitro, in vivo, and in silico methods. The antioxidant capacity of the ZRRB extract was measured using both the DPPH radical assay and the total antioxidant activity test. The oral glucose tolerance test (OGTT) and alloxan-induced diabetic mice model were also used to examine in vivo antidiabetic efficacy. Phytochemicals identification was done by GCMS analysis. Additionally, computational methods such as molecular docking, ADMET analysis, and molecular dynamics (MD) modeling were performed to determine the above pharmacological effects. The extract demonstrated significant DPPH scavenging activity (IC50 = 42.65 μg/mL). In the OGTT test and alloxan-induced diabetes mice model, the extract effectively lowered blood glucose levels. Furthermore, in vitro inhibition of pancreatic α-amylase studies demonstrated the ZRRB extract as a good antidiabetic crude drug (IC50 = 81.45 μg/mL). GCMS investigation confirmed that the crude extract contains 16 major phytoconstituents, which were docked with human peroxiredoxin-5, α-amylase, and sulfonylurea receptor 1. Docking and pharmacokinetic studies demonstrated that among 16 phytoconstituents, 6H-indolo[3,2,1-de] [1,5]naphthyridin-6-one (CID: 97176) showed the highest binding affinity to targeted enzymes, and imitated Lipinski's rule of five. Furthermore, MD simulation data confirmed that the aforementioned compound is very steady to the binding site of α-amylase and sulfonylurea receptor 1 receptors. Findings from in vitro, in vivo and in silico investigation suggest that ZRRB extract contains a lead compound that could be a potent source of antidiabetic drug candidate.

High-Altitude Medicinal Plants as Promising Source of Phytochemical Antioxidants to Combat Lifestyle-Associated Oxidative Stress-Induced Disorders. Pharmaceuticals (Basel) 2024; 17:975. [PMID: 39204080 PMCID: PMC11357401 DOI: 10.3390/ph17080975] [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: 06/22/2024] [Revised: 07/14/2024] [Accepted: 07/18/2024] [Indexed: 09/03/2024] Open
Abstract
Oxidative stress, driven by reactive oxygen, nitrogen, and sulphur species (ROS, RNS, RSS), poses a significant threat to cellular integrity and human health. Generated during mitochondrial respiration, inflammation, UV exposure and pollution, these species damage cells and contribute to pathologies like cardiovascular issues, neurodegeneration, cancer, and metabolic syndromes. Lifestyle factors exert a substantial influence on oxidative stress levels, with mitochondria emerging as pivotal players in ROS generation and cellular equilibrium. Phytochemicals, abundant in plants, such as carotenoids, ascorbic acid, tocopherols and polyphenols, offer diverse antioxidant mechanisms. They scavenge free radicals, chelate metal ions, and modulate cellular signalling pathways to mitigate oxidative damage. Furthermore, plants thriving in high-altitude regions are adapted to extreme conditions, and synthesize secondary metabolites, like flavonoids and phenolic compounds in bulk quantities, which act to form a robust antioxidant defence against oxidative stress, including UV radiation and temperature fluctuations. These plants are promising sources for drug development, offering innovative strategies by which to manage oxidative stress-related ailments and enhance human health. Understanding and harnessing the antioxidant potential of phytochemicals from high-altitude plants represent crucial steps in combating oxidative stress-induced disorders and promoting overall wellbeing. This study offers a comprehensive summary of the production and physio-pathological aspects of lifestyle-induced oxidative stress disorders and explores the potential of phytochemicals as promising antioxidants. Additionally, it presents an appraisal of high-altitude medicinal plants as significant sources of antioxidants, highlighting their potential for drug development and the creation of innovative antioxidant therapeutic approaches.

Abstract
Alzheimer's disease (AD) continues to be a worldwide health concern, demanding innovative therapeutic approaches. This study investigates the neuroprotective potential of herbal compounds by scrutinizing their interactions with Beta-Secretase-1 (BACE1). Through comprehensive molecular docking analyses, three compounds, Masticadienonic acid (ΔG: -9.6 kcal/mol), Hederagenin (ΔG: -9.3 kcal/mol), and Anthocyanins (ΔG: -8.1 kcal/mol), emerge as promising BACE1 ligands, displaying low binding energies and strong affinities. ADME parameter predictions, drug-likeness assessments, and toxicity analyses reveal favorable pharmacokinetic profiles for these compounds. Notably, Masticadienonic Acid exhibits optimal drug-likeness (-3.3736) and negligible toxicity concerns. Hederagenin (drug-likeness: -5.3272) and Anthocyanins (drug-likeness: -6.2041) also demonstrate promising safety profiles. Furthermore, pharmacophore modeling elucidates the compounds' unique interaction landscapes within BACE1's active site. Masticadienonic acid showcases seven hydrophobic interactions and a hydrogen bond acceptor interaction with Thr232. Hederagenin exhibits a specific hydrogen bond acceptor interaction with Trp76, emphasizing its selective binding. Anthocyanins reveal a multifaceted engagement, combining hydrophobic contacts and hydrogen bond interactions with key residues. In conclusion, Masticadienonic acid, Hederagenin, and Anthocyanins stand out as promising candidates for further experimental validation, presenting a synergistic balance of efficacy and safety in combating AD through BACE1 inhibition.

Abstract
BACKGROUND AND OBJECTIVES Maternal hypoxia disrupts neural development and subsequently leads to cerebral palsy and epilepsy in newborns. Hypoxia plays a role in neurodegeneration by increasing oxidative stress. Pistacia atlantica is known as an important antioxidant, and its anti-inflammatory and antioxidant effects have been shown in various studies. This study aims to investigate the effects of methanolic extract of P. atlantica leaves (MEPaLs) on the oxidative parameters in the serum of rats affected by maternal hypoxia. MATERIAL AND METHODS In this study, eight pregnant rats were used. The newborns were divided into four groups, including the control and the hypoxia groups, which are affected by maternal hypoxia, hypoxia + MEPaL 100 mg/kg, and hypoxia + MEPaL 150 mg/kg. MEPaL was injected (i.p) for 21 days into the neonatal rats after the lactation period. Hypoxia was induced by keeping pregnant rats in a hypoxic chamber with 7% oxygen and 93% nitrogen intensity for 3 h on the 20th day of pregnancy. Behavioral changes were measured using open-field and rotarod tests. Finally, biomarkers of oxidative stress, nitric oxide (NO), glutathione (GSH), GSSG, TAS, TOS, and oxidative stress index (OSI) were measured in the experimental groups. RESULTS Behavioral results showed that the anxiety behavior in the hypoxia group increased, but the motor activity (moved distance and movement speed) decreased. Moreover, the amount of time spent maintaining balance on the rotarod rod was significantly decreased in the hypoxia group. The concentration of NO in the group of hypoxia + MEPaL 100 mg/kg showed a significant decrease, and MEPaL 100, and 150 mg/kg + hypoxia also increased the concentration of GSH and decreased GSSG. In addition, MEPaL100 and 150 mg/kg caused a significant increase in the ratio of GSH to GSSG and decreased OSI and total oxidant capacity. CONCLUSIONS Oxidative stress increased in the rats affected by maternal hypoxia and may be the main mechanism for motor activity impairment and balance disturbance, whereas MELaL improved motor performance by decreasing oxidative stress.

Abstract
In recent years, discovering new drug candidates has become a top priority in research. Natural products have proven to be a promising source for such discoveries as many researchers have successfully isolated bioactive compounds with various activities that show potential as drug candidates. Among these compounds, phenolic compounds have been frequently isolated due to their many biological activities, including their role as antioxidants, making them candidates for treating diseases related to oxidative stress. The isolation method is essential, and researchers have sought to find effective procedures that maximize the purity and yield of bioactive compounds. This review aims to provide information on the isolation or separation methods for phenolic compounds with antioxidant activities using column chromatography, medium-pressure liquid chromatography, high-performance liquid chromatography, counter-current chromatography, hydrophilic interaction chromatography, supercritical fluid chromatography, molecularly imprinted technologies, and high-performance thin layer chromatography. For isolation or purification, the molecularly imprinted technologies represent a more accessible and more efficient procedure because they can be applied directly to the extract to reduce the complicated isolation process. However, it still requires further development and refinement.

Abstract
Background Pistacia integerrima (PI) galls, being rich in polyphenolic compounds, owing to its high restorative worth and restricted assets and exorbitant utilization lead to the overexploitation of the species and availability issues. It is expected to categorise under the red list of threatened taxa. Ayurveda text Bhaishajaya Ratnavali mentioned Quercus infectoria (QI) as ‘pratinidhi’ or substitute of PI and Yogaratnakara (abhavvarga) text reference indicated Terminalia chebula (TC) having the same therapeutic character as in PI. Hence, this study was focused on the comparative quantification of major polyphenolic compounds in aqueous and hydro-alcoholic extracts of PI, QI and TC by liquid chromatography and tandem mass spectroscopy (LC-MS/MS). Objectives The LC-MS/MS method was used for the determination of polyphenolic compounds in aqueous and hydro-alcoholic extracts of PI, QI and TC. Materials and Methods The LC-MS/MS method was developed for the quantification of targeted polyphenolic compounds and validated in terms of linearity, accuracy, precision, limit of detection and limit of quantification. Analysis performed by LC-MS/MS 6460 C triple quad coupled with Agilent HPLC. The chromatographic separation was performed on the RP C18 column with gradient elution. Results The developed method of LC-MS/MS was used for the quantitative estimation of gallic acid, corilagin acid, caffeic acid, syringic acid, rutin hydrate, ellagic acid, quercetin and morin hydrate in PI, QI and TC. As per method validation parameters, calibration plots were found to be linear, accurate, precise and specific for LC-MS/MS. The calibration plot exhibited an excellent coefficient of determination ( R2 ≥ 0.99), and extraction recovery was found 96.20%–103.71%. Gallic acid and ellagic acid are the most abundant compound among eight targeted polyphenolics in all extracts. Conclusion The finding of LC-MS/MS analysis of polyphenolic compounds in aqueous and hydro-alcoholic extracts indicates that PI, QI and TC are having phytochemical similarities up to an extent in polyphenolic compounds as a secondary metabolite; however, a firmer opinion can be formed after a comparative efficacy study and the evaluation of all three extracts.

Abstract
Pistacia integerrima Stew ex Brandis is a valued medicinal plant used for curing various diseases such as diarrhea, fever, liver disorder, pain, asthma, and inflammation. The aim of this study was the isolation of bioactive leishmanicidal agents from the methanolic extract. The methanolic extract led to the isolation of flavonoids 3,5,7,4/-tetrahydroxy-flavanone (1). The extract and isolated compound 1 were tested for antileishmanial effect. The extract showed a percent effect of 63.09 with an IC50 value (49.32 µM). The isolated compound 1 was more leishmanicidal than the extract with a percent growth inhibition of 68.09. We have performed docking studies on two antileishmanial targets; homology modeled dihydrofolate reductase (DHFR) and pteridine reductase (PTR1) from Leishmania major (L. major). Interaction with important residues of the studied enzymes revealed the possible mechanism of in-vitro activity against promastigotes of L. major.

Abstract
The galls of Pistacia integerrima are used in folk medicine for curing diabetes. The main aim of this study was the purification of flavonoids from galls of P. integerrima. The methanolic extract was subjected to column chromatographic analysis which afforded six flavonoids, namely, 3,5,7,4′-tetrahydroxy-flavanone (1), naringenin (2), 3,5,4′-trihydroxy,7-methoxy-flavanone (3), sakuranetin (4), spinacetin (5), and patuletin (6). These isolated compounds (1–6) were tested against α-glycosidase. The maximum antagonistic effect was noted against compound 6 (97.65%) followed by compound 5 (90.42%) and compound 1 (90.01%) at the same concentration (0.2 μg). The inhibitory potential of all tested compounds was significant with a degree of variation from each other. Docking studies showed that all studied compounds interact with the active site residues via hydrogen bond interactions with hydroxyl groups, and thus, inhibition was enhanced. Hence, this finding would be the first screening of isolated flavonoids for α-glycosidase activity and with the mechanism of action. These flavonoids should be further investigated as candidate drugs for combating diabetes mellitus.

Abstract
OBJECTIVE Sinomenii Caulis (QingFengTeng) and Ramulus Cinnamomi (GuiZhi) are traditional Chinese drugs that have been used for anti-inflammation. In this study, the team plans to find out the material basis of a Chinese herb combination composed of the two herbs with different ratios. METHODS The extracts of the herbal compound with various ratios obtained from ethanol extraction were analyzed by ultra-high-performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry (UHPLC-Q-TOF-MS) and gas chromatography coupled mass spectrometry to identify the basic chemical compounds. Simultaneously, the contents of the eight main components (sinomenine, magnoflorine, laurifoline, dauricine, coumarin, cinnamyl alcohol, cinnamic acid and cinnamaldehyde) from herb formula were determined by gradient elution by high-performance liquid chromatography. Furthermore, the content of sinomenine and cinnamaldehyde were determined by isocratic elution, respectively. RESULTS Eighteen compounds in the herb formula were identified by UHPLC-Q-TOF-MS. The components in the GuiZhi are mostly volatile oils and the kinds of compounds isolated from the formula in the ratio of 4:1 were the most. Wherein eight compounds were identified as the main detection targets in the content determination. CONCLUSION The extraction rate of sinomenine in QingFengTeng was related to the proportion of GuiZhi in the drug pairs. Synchronously, the addition of sinomenine in different proportions also had some influence on the extraction of cinnamaldehyde in GuiZhi. Furthermore, the series of methods was successfully applied to the simultaneous determination of chemical compounds in different samples of QingFengTeng-GuiZhi decoction.

Abstract
Alzheimer's disease (AD) is the number one neurovegetative disease, but its treatment options are relatively few and ineffective. In efforts to discover new strategies for AD therapy, natural products have aroused interest in the research community and in the pharmaceutical industry for their neuroprotective activity, targeting different pathological mechanisms associated with AD. A wide variety of natural products from different origins have been evaluated preclinically and clinically for their neuroprotective mechanisms in preventing and attenuating the multifactorial pathologies of AD. This review mainly focuses on the possible neuroprotective mechanisms from natural products that may be beneficial in AD treatment and the natural product mixtures or extracts from different sources that have demonstrated neuroprotective activity in preclinical and/or clinical studies. It is believed that natural product mixtures or extracts containing multiple bioactive compounds that can work additively or synergistically to exhibit multiple neuroprotective mechanisms might be an effective approach in AD drug discovery.

[PMID: 33801579 PMCID: PMC8067215 DOI: 10.3390/ph14040297] [Citation(s) in RCA: 14] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/12/2021] [Revised: 03/05/2021] [Accepted: 03/13/2021] [Indexed: 12/12/2022] Open
Abstract
Divya-Swasari-Vati (DSV) is a calcium-containing herbal medicine formulated for the symptomatic control of respiratory illnesses observed in the current COVID-19 pandemic. DSV is an Ayurvedic medicine used for the treatment of chronic cough and inflammation. The formulation has shown its pharmacological effects against SARS-CoV-2 induced inflammation in the humanized zebrafish model. The present inventive research aimed to establish comprehensive quality parameters of the DSV formulation using validated chromatographic analytical tools. Exhaustive identification of signature marker compounds present in the plant ingredients was carried out using ultra performance liquid chromatography-quadrupole time-of-flight mass spectrometry (UPLC/QToF MS). This was followed by simultaneous estimation of selected marker components using rapid and reliable high-performance liquid chromatography (HPLC) analysis. Eleven marker components, namely gallic acid, protocatechuic acid, methyl gallate, ellagic acid, coumarin, cinnamic acid, glycyrrhizin, eugenol, 6-gingerol, piperine and glabridin, were selected out of seventy-four identified makers for the quantitative analysis in DSV formulation. Validation of the HPLC method was evaluated by its linearity, precision, and accuracy tests as per the International Council of Harmonization (ICH) guidelines. Calibration curves for the eleven marker compounds showed good linear regression (r2 > 0.999). The relative standard deviation (RSD) value of intraday and interday precision tests were within the prescribed limits. The accuracy test results ranged from 92.75% to 100.13%. Thus, the present inclusive approach is first of its kind employing multi-chromatographic platforms for identification and quantification of the marker components in DSV, which could be applied for routine standardization of DSV and other related formulations.

Abstract
Medicines derived from plants are preferred over synthetic therapeutic agents in treating different diseases. Ziziphus oxyphylla (a member of Rhamnaceae family) is a medicinal plant used as a remedy of different diseases in Greek and Ayurveda medical systems. Z. oxyphylla roots were shade dried and then subjected to extraction of bioactive compounds using different solvent systems and silica gel. From ethyl acetate fraction, three compounds viz., p-coumaric acid (V), 3,4-dimethoxy benzoic acid (VI), and 4-heptyloxy benzoic acid (VII) were isolated in pure form. The selection of ethyl acetate fraction for isolation was based on HPLC profiling of crude extract and different fractions. These compounds were characterized by different spectroscopic techniques and evaluated for their in vitro antioxidant, anticholinesterase, α–glucosidase, and α-amylase inhibitory potentials. To find out possible binding interactions of V with AChE and BChE crystals, in-silico docking studies were also carried out. Compound V showed maximum scavenging capabilities of DPPH and ABTS free radicals with IC50 values of 69 and 62 μg/mL respectively. Excellent percent inhibition (83.4 ± 0.5% at highest concentration 1000 μg/mL) of acetylcholinesterase (AChE) was exhibited by compound V (IC50 = 80 μg/mL); whereas, for the mentioned concentration, 83.2 ± 1.1% inhibition (IC50 = 90 μg/mL) of butyrylcholinesterase (BChE) was observed as well. The compound VI exhibited highest % inhibition against α-glucosidase (IC50 = 84 μg/mL) whereas α-amylase was more potently inhibited by compound V (% inhibition = 86.8 % and IC50 = 85 μg/mL). Docking scores of -1.391 Kcal/mol (BChE) and –6.253 Kcal/mol (AChE) were recorded using molecular docking software. Compound V exhibited strong free radical scavenging and anticholinesterase potentials suggesting that it can be effectively used to treat oxidative stress and dementia in human.

Abstract
Exposure to environmental toxicants such as Bisphenol A (BPA) has raised serious health issues globally particularly in developing countries. It is ubiquitously used in the manufacturing of canned food and feeding bottles. BPA generated reactive oxygen species can lead to several diseases including cardiotoxicity. However, the endpoints stimulated in BPA cardiotoxicity yet need to be investigated. The current study was aimed to investigate the underlying molecular pathways which may contribute in revealing the protective effects of Pistacia integerrima against BPA induced oxidative stress. The dose of 100 µg/kg BW of BPA, 200 mg/kg BW P. integerrima, and 4 mg/kg BW melatonin was administered to Sprague Dawley rats. Present results of western blotting and qRT-PCR showed the increased expression of p53, PUMA and Drp1, while downregulation of Ubc13 in heart tissues of BPA treated group whereas the levels were reversed upon treatment with P. integerrima. The role of BPA in heart tissue apoptosis was further confirmed by the increased level of P-p53, cytochrome C and disrupted cellular architecture whereas the P. integerrima has shown its ameliorative potential by mitigating the adverse effects of BPA. Moreover, the oxidant, antioxidant, lipid, and liver markers profile has also revealed the therapeutic potential of P. integerrima by maintaining the levels in the normal range. However, melatonin has also manifested the normalized expression of apoptotic markers, biochemical markers, and tissue architecture. Conclusively, the data suggest that P. integerrima may be a potential candidate for the treatment of BPA induced toxicity by neutralizing the oxidative stress through Ubc13/p53 pathway.

Abstract
AbstractThioureas and their derivatives are organosulfur compounds having applications in numerous fields such as organic synthesis and pharmaceutical industries. Symmetric thiourea derivatives were synthesized by the reaction of various anilines with CS2. The synthesized compounds were characterized using the UV-visible and nuclear magnetic resonance (NMR) spectroscopic techniques. The compounds were screened forin vitroinhibition of α-amylase, α-glucosidase, acetylcholinesterase (AChE), and butyrylcholinesterase (BuChE) enzymes and for their antibacterial and antioxidant potentials. These compounds were fed to Swiss male albino mice to evaluate their toxicological effects and potential to inhibit glucose-6-phosphatase (G6Pase) inhibition. The antibacterial studies revealed that compound4was more active against the selected bacterial strains. Compound1was more active against 2,2-diphenyl-1-picrylhydrazyl and 2,2’-Azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) free radicals, AChE, BuChE, and α-glucosidase. Compound2was more potent against α-amylase and G6Pase. Toxicity studies showed that compound4is safe as it exerted no toxic effect on any of the hematological and biochemical parameters or on liver histology of the experimental animals at any studied dose rate. The synthesized compounds showed promising antibacterial and antioxidant potential and were very active (bothin vitroandin vivo) against G6Pase and moderately active against the other selected enzymes used in this study.

Abstract
:
Five metabolites were isolated by chromatographic methods from the fruit stems
of P. vera and their chemical structures were characterized as masticadienonic acid (1),
tirucallol (2), masticadienolic acid (3), pistachionic acid (4) and inulobiose (5) via FT-IR,
1H-NMR, 13C-NMR, 1D-NMR and 2D-NMR. Pistachionic acid (4), a new shikimic acid
derivative, was isolated from the ethanol extract for the first time. The hexane, chloroform,
ethanol extracts and pure metabolites exhibited antidiabetic properties by inhibiting α-
glycosidase and α-amylase enzymes at different rates. Their inhibitory effects against the α-
glycosidase enzyme were also higher than that of the acarbose (IC50=10.30 mg/mL). Masticadienolic
acid (3) (IC50=0.03 mg/mL), masticadienonic acid (1) (IC50=0.13 mg/mL) and
hexane extract (IC50=0.09 mg/mL) with the lowest IC50 values were found to be most active
substances. Nevertheless, the inhibitory effect of acarbose against the α-amylase enzyme was determined to be
higher than the inhibition effects of the extracts and pure metabolites. According to the IC50 values, the best
inhibitors against the α-amylase were ethanol extract (IC50=5.17 mg/mL), pistachionic acid (4) (IC50=7.35
mg/mL), tirucallol (2) (IC50=7.58 mg/mL) and masticadienolic acid (3) (IC50=8.22 mg/mL), respectively among
the applications. In addition, anticholinesterase properties of the extracts and pure metabolites were investigated
by testing the inhibitory properties against acetylcholine esterase (AChE) and butrylcholine esterase (BChE)
enzymes activities. The results showed that the anticholinesterase properties of all extracts and pure metabolites
were weaker than those of the commercial cholinesterase inhibitors, neostigmine and galantamine, and all applications
reduced the activity of these enzymes at very high concentrations.

Abstract
Over the past few decades, complementary medicine therapy using medicinal plants have been developed in healthcare. Phytochemical studies about medicinal plants have been conducted to verify their potency as medicinal remedies in modern therapeutics. Dipterocarpus littoralis commonly known as Meranti Jawa in Indonesia is traditionally used to treat diseases such as diarrhea, diabetic and malaria. This study aimed to isolate bioactive compounds from D. littoralis using bioguided fractionation method. The bioactivity measured were antioxidant, antidiabetic, and antiplasmodial activity. Alpha-glucosidase and alpha-amylase assays were applied to estimate the in vitro antidiabetic activity of D. littoralis. The antioxidant activities were determined by using the free radical scavenging assays 1,1-diphenyl-2-picrylhydrazyl (DPPH) and 2-2″-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS). Analysis of total flavonoid and phenolic contents were expressed as Quercetin Equivalent (QE) and Gallic Acid Equivalent (GAE), respectively. The in vitro antiplasmodial activity test of methanol extract of D. littoralis was also conducted against Plasmodium falciparum strain 3D7. Purification of the ethyl acetate fraction of the methanol extract of D. littoralis resulted in an oligostilbenes namely α-viniferin (1). The structure of the α-viniferin was characterized by comprehensive spectral analysis including IR, 1D and 2D NMR, and in comparison with the literature data. Compound 1 showed an alpha-glucosidase and alpha-amylase inhibitory activity with IC50 values of 256.17 and 212.79 μg/mL, respectively. The in vitro antiplasmodial activity test against Plasmodium falciparum strain 3D7 at a concentration of 100 μg/mL revealed a strong antiplasmodial inhibitory activity with IC50 value of 2.76 μg/mL. Our findings indicated that α-viniferin (1) which is isolated from D. littoralis extract could be regarded as potential antidiabetic and antiplasmodial resources in the future.

Abstract
Like other vegetables, Pisum sativum L. also faces storage and degradation problems. To enhance their resistance and make them enable to cope with the deterioration problems during storage, the current study was designed to develop two resistant lines of P. sativum in terms of phenolic contents and genotypes. The phenolic compounds generally have antioxidant properties and deterioration during storage which are usually due to oxidation caused by free radicals. Thus, if a variety has high phenolic contents these problems will be coped in a better way. The genotype of a plant is also important in this regard, and the best adopted species would survive in unfavorable conditions. First, the phenolic and flavonoid contents were determined in the crude extract using the Folin-Ciocalteu method. Then, the identification and quantification of phenolic compounds were carried out in the developed lines of selected plants PL-04 and PL-05, as well as in the parental varieties [Climax (female) and Falan (male)] via HPLC. DPPH assay was used to determine the free radical scavenging capabilities of the extracts of the developed verities. The genotypic differences were confirmed by DNA fingerprinting using advanced simple sequence repeat (SSR) markers. The HPLC analysis of PL-04 confirmed the presence of three phenolic compounds in an appreciable amount which exhibited a higher antioxidant activity against DPPH radicals, while in the parental varieties, two phenolic compounds were identified and exhibited lower antioxidant activities. PL-04 was found rich in phenolic compounds and affectively scavenge-free radicals which would therefore be resistant to oxidation and degradation caused by free radicals. Comparing the present findings with our previous one, P-04 was found to be resistant to powdery mildew; it was concluded that the most probable reason of the resistance was the high phenolic contents and thus long shelf life.

Abstract
Background In this study, 2 symmetrical and 3 unsymmetrical thioureas were synthesized to evaluate their antioxidant, antibacterial, antidiabetic, and anticholinesterase potentials. Methods The symmetrical thioureas were synthesized in aqueous media in the presence of sunlight, using amines and CS2 as starting material. The unsymmetrical thioureas were synthesized using amines as a nucleophile to attack the phenyl isothiocyanate (electrophile). The structures of synthesized compounds were confirmed through H1 NMR. The antioxidant potential was determined using DPPH and ABTS assays. The inhibition of glucose-6-phosphatase, alpha amylase, and alpha glucosidase by synthesized compounds was used as an indication of antidiabetic potential. Anticholinesterase potential was determined from the inhibition of acetylcholinesterase and butyrylcholinesterase by the synthesized compounds. Results The highest inhibition of glucose-6-phosphatase was shown by compound V (03.12 mg of phosphate released). Alpha amylase was most potently inhibited by compound IV with IC50 value of 62 µg/mL while alpha glucosidase by compound III with IC50 value of 75 µg/mL. The enzymes, acetylcholinesterase, and butyrylcholinesterase were potently inhibited by compound III with IC50 of 63 µg/mL and 80 µg/mL respectively. Against DPPH free radical, compound IV was more potent (IC50 = 64 µg/mL) while ABTS was more potently scavenged by compound I with IC50 of 66 µg/mL. The antibacterial spectrum of synthesized compounds was determined against Gram-positive bacteria (Staphylococcus aureus) and Gram-negative bacteria (Agrobacterium tumefaction and Proteus vulgaris). Compound I and compound II showed maximum activity against A. tumefaction with MIC values of 4.02 and 4.04 µg/mL respectively. Against P. vulgaris, compound V was more active (MIC = 8.94 µg/mL) while against S. aureus, compound IV was more potent with MIC of 4.03 µg/mL. Conclusion From the results, it was concluded that these compounds could be used as antibacterial, antioxidant, and antidiabetic agents. However, further in vivo studies are needed to determine the toxicological effect of these compounds in living bodies. The compounds also have potential to treat neurodegenerative diseases.

Abstract
Background Traditionally, Grewia optiva is widely used for the treatment of many diseases like dysentery, fever, typhoid, diarrhea, eczema, smallpox, malaria and cough. Methods Shade-dried roots of G. optiva were extracted with methanol. Based on HPLC results, chloroform and ethyl acetate fractions were subjected to silica column isolation and four compounds: glutaric acid (V), 3,5 dihydroxy phenyl acrylic acid (VI), (2,5 dihydroxy phenyl) 3',6',8'-trihydroxyl-4H chromen-4'-one (VII) and hexanedioic acid (VIII) were isolated in pure form. Ellman’s assay was used to determine the anticholinesterase potential of isolated compounds while their antioxidant potential was estimated by DPPH and ABTS scavenging assays. Results Amongst the isolated compounds, VI and VII exhibited excellent percent inhibition of acetylcholinesterase (AChE) and butyrylcholinesterase (BChE) (83.23±1.11, 82.72±2.20 and 82.11±2.11, 82.23±1.21, respectively, at 1000 µg/mL) with IC50 of 76, 90, 78 and 92 µg/mL, respectively. Highest percent radicals scavenging against DPPH and ABTS (87.41±1.20 and 86.13±2.31) with IC50 of 64 and 65 µg/mL, respectively, were observed for compound VII. Molecular docking studies also supported the binding of compound VI and VII with the target enzyme. The para-hydroxyl group of the phenolic moiety is formed hydrogen bonds with the active site water molecule and the side chain carbonyl and hydroxyl residues of enzyme. Conclusion The isolated compounds inhibited the DPPH and ABTS-free radicals, and AChE and BChE enzymes. It was concluded that these compounds could be used in relieving the oxidative stress and pathological symptoms associated with excessive hydrolysis of acetyl and butyryl choline. The results of the study were supported by docking studies for compounds VI and VII.

Revathi T, Thambidurai S. Cytotoxic, antioxidant and antibacterial activities of copper oxide incorporated chitosan-neem seed biocomposites. Int J Biol Macromol 2019; 139:867-878. [PMID: 31376446 DOI: 10.1016/j.ijbiomac.2019.07.214] [Citation(s) in RCA: 23] [Impact Index Per Article: 4.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/22/2019] [Revised: 07/15/2019] [Accepted: 07/30/2019] [Indexed: 02/08/2023]
Abstract
In this study biopolymer-inorganic material of chitosan‑copper oxide-neem seed (CS-CuO-NS) biocomposite was successfully synthesized by simple precipitation method and characterized by FT-IR, XRD, HR-SEM, TEM and TGA analyses. From HR-SEM and TEM analysis, CS-CuO-NS biocomposite shows flower and needle like structure respectively. The size of the as prepared CS-CuO-NS biocomposite is found to be 20-100 nm. All the synthesized materials were tested for antibacterial activity against both gram positive like Staphylococcus aureus (S. aureus) and Streptococcus pyogenes (S. pyogenes) and gram negative like Escherichia coli (E. coli) and Klebsiella aerogenes (K. aerogenes) bacterial strains. The maximum zone of inhibition is obtained for CS-CuO-NS biocomposite against S. aureus (23 mm), S. pyogenes (21 mm), E. coli (22 mm) and K. aerogenes (20 mm). The minimal inhibitory concentration (MIC) and minimal bactericidal concentration (MBC) were determined. The antioxidant activity was determined by free radicals scavenging such as 1, 1-Diphenyl-2-picryhydrazyl (DPPH) and 2, 2-azinobis (3-ethylbenzothiazoline-6-sulfonic acid) (ABTS). Furthermore, the cytotoxicity effect was investigated against human breast cancer (MCF-7) cell line and the highest cytotoxicity (IC50:16.33 μg/mL) is found to be in biocomposite. From the results of antibacterial, antioxidant and cytotoxic activities, it is concluded that CS-CuO-NS biocomposite may be suitable for biomedical applications.
