Anethole alleviates Doxorubicin-induced cardiac and renal toxicities: Insights from network pharmacology and animal studies. Chem Biol Interact 2024; 401:111155. [PMID: 39029857 DOI: 10.1016/j.cbi.2024.111155] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/07/2024] [Revised: 07/14/2024] [Accepted: 07/16/2024] [Indexed: 07/21/2024]
Abstract
Doxorubicin (Dox) is widely used as a chemotherapy drug, while anethole (AN) is primarily known as the main aromatic component in various plant species. This research focused on the impact of AN on the cardiac and renal toxicity induced by Dox and to understand the underlying mechanisms. For cardiac toxicity, Wistar rats were categorized into four groups: a Control group; a Dox group, where rats received 2.5 mg/kg of Dox intraperitoneally every other day; and two Dox + AN groups, where animals were administered Dox (2.5 mg/kg/every other day, IP) along with 125 mg/kg or 250 mg/kg of AN, respectively. The renal toxicity study included similar groups, with the Dox group receiving a single dose of 20 mg/kg of Dox intraperitoneally on the tenth day, and the Dox + AN groups receiving 125 mg/kg and 250 mg/kg of AN for two weeks, alongside the same dose of Dox (20 mg/kg, IP, once on the 10th day). Parameters assessed included ECG, cardiac injury markers (CK, CK-MB, and LDH), and kidney function tests (Cr, BUN, uric acid, LDL, Kim-1, NGAL, and CysC). Antioxidant activity, lipid peroxidation, inflammation, and apoptotic markers were also monitored in heart and renal tissues. Gene expression levels of the TLR4/MyD88/NFκB pathway, along with Bax and Bcl-2, were evaluated. Dox significantly altered ECG, elevated cardiac injury markers, and renal function markers. It also augmented gene expressions of TLR4/MyD88/NFκB, amplified oxidative stress, inflammatory cytokines and apoptotic markers. Conversely, AN reduced cardiac injury markers and kidney function tests, improved ECG, diminished TLR4/MyD88/NFκB gene expression, and alleviated oxidative stress by increasing antioxidant enzyme activities and reducing inflammatory cytokines. AN also enhanced Bcl-2 levels and inhibited Bax and the cleavage of caspase-3 and 9. AN countered the lipid peroxidation, oxidative stress, inflammation, and apoptosis induced by Dox, marking it as a potential preventive strategy against Dox-induced nephrotoxic and cardiotoxic injuries.

Barbosa-Ferreira BDS, da Silva FER, Gomes-Vasconcelos YDA, Joca HC, Coelho-de-Souza AN, Ferreira-da-Silva FW, Leal-Cardoso JH, da Silva-Alves KS. Anethole Prevents the Alterations Produced by Diabetes Mellitus in the Sciatic Nerve of Rats. Int J Mol Sci 2024; 25:8133. [PMID: 39125701 PMCID: PMC11312180 DOI: 10.3390/ijms25158133] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/23/2024] [Revised: 07/12/2024] [Accepted: 07/16/2024] [Indexed: 08/12/2024] Open
Abstract
Anethole is a terpenoid with antioxidant, anti-inflammatory, and neuronal blockade effects, and the present work was undertaken to study the neuroprotective activity of anethole against diabetes mellitus (DM)-induced neuropathy. Streptozotocin-induced DM rats were used to investigate the effects of anethole treatment on morphological, electrophysiological, and biochemical alterations of the sciatic nerve (SN). Anethole partially prevented the mechanical hyposensitivity caused by DM and fully prevented the DM-induced decrease in the cross-sectional area of the SN. In relation to electrophysiological properties of SN fibers, DM reduced the frequency of occurrence of the 3rd component of the compound action potential (CAP) by 15%. It also significantly reduced the conduction velocity of the 1st and 2nd CAP components from 104.6 ± 3.47 and 39.8 ± 1.02 to 89.9 ± 3.03 and 35.4 ± 1.56 m/s, respectively, and increased the duration of the 2nd CAP component from 0.66 ± 0.04 to 0.82 ± 0.09 ms. DM also increases oxidative stress in the SN, altering values related to thiol, TBARS, SOD, and CAT activities. Anethole was capable of fully preventing all these DM electrophysiological and biochemical alterations in the nerve. Thus, the magnitude of the DM-induced neural effects seen in this work, and the prevention afforded by anethole treatment, place this compound in a very favorable position as a potential therapeutic agent for treating diabetic peripheral neuropathy.

Abstract
Previously, some bacteria were shown to harbour enzymes capable of catalysing the oxidative cleavage of the double bond of t-anethole and related compounds. The cofactor dependence of these enzymes remained enigmatic due to a lack of biochemical information. We report on catalytic and structural details of a representative of this group of oxidative enzymes: t-anethole oxygenase from Stenotrophomonas maltophilia (TAOSm). The bacterial enzyme could be recombinantly expressed and purified, enabling a detailed biochemical study that has settled the dispute on its cofactor dependence. We have established that TAOSm contains a tightly bound b-type heme and merely depends on dioxygen for catalysis. It was found to accept t-anethole, isoeugenol and O-methyl isoeugenol as substrates, all being converted into the corresponding aromatic aldehydes without the need of any cofactor regeneration. The elucidated crystal structure of TAOSm has revealed that it contains a unique active site architecture that is conserved for this distinct class of heme-containing bacterial oxygenases. Similar to other hemoproteins, TAOSm has a histidine (His121) as proximal ligand. Yet, unique for TAOs, an arginine (Arg89) is located at the distal axial position. Site directed mutagenesis confirmed crucial roles for these heme-liganding residues and other residues that form the substrate binding pocket. In conclusion, the results reported here reveal a new class of bacterial heme-containing oxygenases that can be used for the cleavage of alkene double bonds, analogous to ozonolysis in organic chemistry.

Abstract
Background Metabolic syndrome (MetS) is a cluster of physiological, biochemical, clinical, and metabolic conditions that aggravate the risk of severe diseases such as cardiovascular disease, type 2 diabetes mellitus, and fatty liver. Several dietary molecules have been considered preventive compounds for MetS. Anethole, a natural phenylpropanoid, has been found to protect against MetS and its associated components. Aim This systematic review aims to provide an overview of the preclinical evidence supporting the protective effects of dietary anethole against MetS and the associated diseases. Methods A literature search was performed using Web of Sciences, PubMed, Scopus, and Google Scholar to identify studies reporting the protective effects of dietary anethole against MetS, without any time restrictions. Review articles, letters to editors, editorials, unpublished results, and non-English papers were excluded from the study. Results The results showed that anethole has the potential to effectively protect against the key features of MetS via various mechanisms, including antioxidant and anti-inflammatory effects, stimulating insulin secretion from β-cells, mediating oxidative stress, modulation of the mTOR/PPARγ axis, arterial remodeling, and improvement of vascular relaxation. Conclusion Anethole modulates several molecular pathways that are implicated in the pathogenesis of MetS. Future in vitro and animal investigations should be conducted to explore other anti-MetS signaling pathways of anethole. Additionally, well-designed clinical studies are warranted to determine the optimal human dose, bioavailability, and pharmacokinetic characteristics of this dietary compound.

Abstract
Isoeugenol is one of several phenylpropenoid compounds that is used as a fragrance, food flavoring agent and in aquaculture as a fish anesthetic. Carcinogenicity testing in rats and mice by NTP resulted in clear evidence of carcinogenicity (hepatic adenomas/carcinomas) in male mice only. A nongenotoxic threshold mode of action (MOA) is postulated for isoeugenol and is discussed considering the IPCS MOA and Human Relevance Framework. The weight of evidence indicates that isoeugenol is not genotoxic and that the carcinogenic outcome in male mice relates directly to the metabolism of individual compounds. Benchmark Dose (BMD) modeling was conducted to determine a Point of Departure (POD) and potential threshold of carcinogenicity. The results of the BMD evaluation for isoeugenol resulted in an estimated POD for carcinogenicity in the male mouse of 8 mg/kg with a lower limit of 4 mg/kg, representing a POD for the determination of an acceptable daily intake. With application of uncertainty factors, an ADI of 40 μg/kg is calculated. This daily dose in humans would be protective of human health, including carcinogenicity. A corresponding maximum residual level (MRL) of 3200 μg/kg fish is also estimated based on this POD that considers the threshold MOA.

Abstract
Oral streptococci are the major group of bacteria in the oral cavity. Some of their species cause oral diseases that may lead to tooth loss and quality-of-life reduction, such as dental caries. One of prevention techniques to promote oral health is rinsing mouthwash after toothbrushing. This study aimed to determine the potential uses of local food, also remedy, plant in Thailand called Reaw-Horm or Etlingera pavieana for alternative herbal mouthwash. The essential oil from E. pavieana rhizome (Eo) is used for anti-streptococci including Streptococcus mutans and Streptococcus sobrinus and anti-biofilm activities. The main components of Eo are methyl chavicol (MC) and trans-anethole (TA). The disk diffusion method showed the inhibition zone of Eo in a dose-dependent manner. The minimum inhibitory concentration (MIC) of Eo and TA was >1.6 % v/v, and 0.4 % v/v of MC. Regarding anti-biofilm activities, MC showed nearly equal anti-biofilm formation of S. mutans and S. sobrinus, whereas Eo and TA acted toward S. sobrinus more than S. mutans biofilm. Sub-MIC killing effects on cells under biofilm were observed in Eo and MC. Therefore, MC was recommended as an active compound for anti-streptococci activities. Biocompatibility of Eo and MC were shown to be safe for epidermal cell lines. Herbal mouthwashes containing Eo were developed and had antioxidant and antimicrobial actions with established for 3 months. This study provides in vitro support on the use of herbal mouthwash with antioxidant and antimicrobial activities for dental caries prevention and well-being of individuals.

Abstract
Anethole is a phenolic compound synthesized by many aromatic plants. Anethole is a substance that humans can safely consume and has been studied for years as a biologically active molecule to treat a variety of conditions, including nerve damage, gastritis, inflammation, and nociception. Anethole is thought to carry out its biological activities through direct interaction with ion channels. Anethole is beneficial for neurodegenerative Alzheimer's and Parkinson's diseases. Nevertheless, nothing has been investigated regarding the effects of anethole on voltage-gated Na+ channels (VGSCs), which are major players in neuronal function. We used cultured dorsal root ganglion neurons from neonatal rats as a source of natively expressed VGSCs for electrophysiological studies using the whole-cell patch-clamp technique. Our data show that anethole interacts directly with VGSCs. Anethole quickly blocks and unblocks (when removed) voltage-activated Na+ currents in this preparation in a fully reversible manner. Anethole's binding affinity to these channels increases when the inactive states of these channels are populated, similar to lidocaine's effect on the same channels. Our data show that anethole inhibits neuronal activity by blocking VGSCs in a state-dependent manner. These findings relate to the putative anesthetic activity attributable to anethole, in addition to its potential benefit in neurodegenerative diseases.

Abstract
Propenylbenzenes, including isosafrole, anethole, isoeugenol, and their derivatives, are natural compounds found in essential oils from various plants. Compounds of this group are important and valuable, and are used in the flavour and fragrance industries as well as the pharmaceutical and cosmetic industries. The aim of this study was to develop an efficient process for synthesising oxygenated derivatives of these compounds and evaluate their potential biological activities. In this paper, we propose a two-step chemo-enzymatic method. The first step involves the synthesis of corresponding diols 1b-5b from propenylbenzenes 1a-5avia lipase catalysed epoxidation followed by epoxide hydrolysis. The second step involves the microbial oxidation of a diasteroisomeric mixture of diols 1b-5b to yield the corresponding hydroxy ketones 1c-4c, which in this study was performed on a preparative scale using Dietzia sp. DSM44016, Rhodococcus erythropolis DSM44534, R. erythropolis PCM2150, and Rhodococcus ruber PCM2166. Application of scaled-up processes allowed to obtain hydroxy ketones 1-4c with the following yield range 36-62.5%. The propenylbenzene derivatives thus obtained and the starting compounds were tested for various biological activities, including antimicrobial, antioxidant, haemolytic, and anticancer activities, and their impact on membrane fluidity. Fungistatic activity assay against selected strains of Candida albicans results in MIC50 value varied from 37 to 124 μg/mL for compounds 1a, 3a-c, 4a,b, and 5a,b. The highest antiradical activity was shown by propenylbenzenes 1-5a with a double bond in their structure with EC50 value ranged from 19 to 31 μg/mL. Haemolytic activity assay showed no cytotoxicity of the tested compounds on human RBCs whereas, compounds 2b-4b and 2c-4c affected the fluidity of the RBCs membrane. The tested compounds depending on their concentration showed different antiproliferative activity against HepG2, Caco-2, and MG63. The results indicate the potential utility of these compounds as fungistatics, antioxidants, and proliferation inhibitors of selected cell lines.

Abstract
A completely new method for the determination of trans-anethole (TAN) based on the anodic oxidation of this flavouring substance in pure acetonitrile using differential-pulse voltammetry has been developed. A nonaqueous carbon paste electrode bulk-modified with solid sodium dodecyl sulphate of 40 % (w/w) content was chosen as optimum. To propose TAN electrode reaction mechanism, its electrochemical behaviour was investigated at glassy carbon electrode in nonaqueous media. At optimum working conditions, the current response could be calibrated within a linear range 2-200 µmolL-1 TAN, a coefficient of determination of 0.9971, a sensitivity of 0.1122µALµmol-1, and a detection limit of 0.7 µmolL-1. A satisfactory precision (relative standard deviation of 4 %) has been achieved. The validation performed by analysis of spices and sweets provided comparable results with reference reverse-phase HPLC with spectrophotometric detection, thus confirming the practical use of the developed voltammetric method in food analysis.

Abstract
The FEMA Expert Panel program to re-evaluate the safety of natural flavor complexes (NFCs) used as flavoring ingredients in food has resulted in the publication of an updated constituent-based procedure as well as publications on the safety evaluation of many botanical-derived NFCs. This publication, ninth in the series and related to the ninth publication, describes the affirmation of the generally recognized as safe (GRAS) status for NFCs with propenylhydroxybenzene and allylalkoxybenzene constituents under their conditions of intended use as flavoring ingredients added to food. The Panel's procedure applies the threshold of toxicological concern (TTC) concept and evaluates relevant data on absorption, metabolism, genotoxic potential and toxicology for the NFCs themselves and their respective constituent congeneric groups. For NFCs containing allylalkoxybenzene constituent(s) with suspected genotoxic potential, the estimated intake of the individual constituent is compared to the TTC for compounds with structural alerts for genotoxicity and if exceeded, a margin of exposure is calculated using BMDL10 values derived from benchmark dose analyses using Bayesian model averaging, as presented in the tenth article of the series. Safety evaluations for NFCs derived from allspice, anise seed, star anise, sweet fennel seed and pimento leaves were conducted and their GRAS status was affirmed for use as flavoring ingredients. The scope of the safety evaluation contained herein does not include added use in dietary supplements or any products other than food.

Abstract
In 2015, the Expert Panel of the Flavor and Extract Manufacturers Association (FEMA) initiated a program for the re-evaluation of the safety of over 250 natural flavor complexes (NFCs) used as flavoring ingredients in food. In this publication, tenth in the series, NFCs containing a high percentage of at least one naturally occurring allylalkoxybenzene constituent with a suspected concern for genotoxicity and/or carcinogenicity are evaluated. In a related paper, ninth in the series, NFCs containing anethole and/or eugenol and relatively low percentages of these allylalkoxybenzenes are evaluated. The Panel applies the threshold of toxicological concern (TTC) concept and evaluates relevant toxicology data on the NFCs and their respective constituent congeneric groups. For NFCs containing allylalkoxybenzene constituent(s), the estimated intake of the constituent is compared to the TTC for compounds with structural alerts for genotoxicity and when exceeded, a margin of exposure (MOE) is calculated. BMDL10 values are derived from benchmark dose analyses using Bayesian model averaging for safrole, estragole and methyl eugenol using EPA's BMDS software version 3.2. BMDL10 values for myristicin, elemicin and parsley apiole were estimated by read-across using relative potency factors. Margins of safety for each constituent congeneric group and MOEs for each allylalkoxybenzene constituent for each NFC were determined that indicate no safety concern. The scope of the safety evaluation contained herein does not include added use in dietary supplements or any products other than food.

Biomed Pharmacother 2023; 158:114153. [PMID: 36566523 DOI: 10.1016/j.biopha.2022.114153] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/05/2022] [Revised: 12/13/2022] [Accepted: 12/21/2022] [Indexed: 12/24/2022] Open
Abstract
The reduction of staphyloxanthin (STX) production in Staphylococcus aureus under trans-anethole (TA) influence was proven in former studies. However, no tests concerning the impact of TA on a biosynthetic pathway of this carotenoid pigment have been published so far. Thus, for the first time, the present preliminary study evaluated the influence of TA on the expression level of genes (crtOPQMN operon and aldH) encoding STX pathway enzymes. Additional attention was paid to the identification of STX and its intermediates. Gene expression and identification of extracted compounds were conducted using quantitative real-time PCR and HPLC-MS techniques, respectively. The analyzes showed no difference in crtM, crtN, crtO, crtP, crtQ, and aldH gene expression between bacterial samples isolated from the non-stimulated (control) medium and the stimulated one with TA. Compared to the control group that showed the presence of all metabolic intermediates and STX, the TA-treated bacteria were characterized by a lack or a significant reduction of the majority of compounds, except 4,4'-diaponeurosporenoate, the content of which was elevated in the TA-treated sample. Moreover, in silico molecular docking analysis revealed that TA is capable to create relatively strong interactions with both 4,4'-diapophytoene synthase and 4,4'-diapophytoene desaturase. The preliminary findings indicate that the previously observed TA effect reducing the number of S. aureus colonies pigmentation is probably not associated with the expression levels of genes encoding STX pathway enzymes. It has been proven that adding TA to the medium can interfere with the formation of STX at different levels of its biosynthetic pathway.

Abstract
Global estimates indicate that over 600 million individuals worldwide consume the areca (betel) nut in some form. Nonetheless, its consumption is associated with a myriad of oral and systemic ailments, such as precancerous oral lesions, oropharyngeal cancers, liver toxicity and hepatic carcinoma, cardiovascular distress, and addiction. Users commonly chew slivers of areca nut in a complex consumable preparation called betel quid (BQ). Consequently, the user is exposed to a wide array of chemicals with diverse pharmacokinetic behavior in the body. However, a comprehensive understanding of the metabolic pathways significant to BQ chemicals is lacking. Henceforth, we performed a literature search to identify prominent BQ constituents and examine each chemical's interplay with drug disposition proteins. In total, we uncovered over 20 major chemicals (e.g., arecoline, nicotine, menthol, quercetin, tannic acid) present in the BQ mixture that were substrates, inhibitors, and/or inducers of various phase I (e.g., CYP, FMO, hydrolases) and phase II (e.g., GST, UGT, SULT) drug metabolizing enzymes, along with several transporters (e.g., P-gp, BCRP, MRP). Altogether, over 80 potential interactivities were found. Utilizing this new information, we generated theoretical predictions of drug interactions precipitated by BQ consumption. Data suggests that BQ consumers are at risk for drug interactions (and possible adverse effects) when co-ingesting other substances (multiple therapeutic classes) with overlapping elimination mechanisms. Until now, prediction about interactions is not widely known among BQ consumers and their clinicians. Further research is necessary based on our speculations to elucidate the biological ramifications of specific BQ-induced interactions and to take measures that improve the health of BQ consumers.

Poult Sci 2022; 102:102397. [PMID: 36565631 PMCID: PMC9801195 DOI: 10.1016/j.psj.2022.102397] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/24/2022] [Revised: 11/29/2022] [Accepted: 12/05/2022] [Indexed: 12/13/2022] Open
Abstract
This study aimed to explore the effects of trans-anethole (TA) on lipopolysaccharide (LPS)-induced acute jejunal inflammation model of broilers. A total of 160 one-day-old broilers (male; Arbor Acres) were randomly allocated into four treatment groups with 8 replicates of 5 birds each. On d 20, the dose of 5 mg/kg body weight LPS solution and the equal amount of sterile saline were intraperitoneally injected into LPS-challenged and unchallenged broilers, respectively. Compared with the control group, LPS decreased (P < 0.05) the villus height (VH) and the ratio of villus height to crypt depth (VCR) but increased (P < 0.05) the crypt depth (CD), meanwhile, enhanced (P < 0.01) the levels of interleukin-6 (IL-6), interleukin-1beta (IL-1β) and tumor necrosis factor-alpha (TNF-α) but decreased (P < 0.01) the level of interleukin-10 (IL-10). The group supplemented with 600 mg/kg of TA had lower (P < 0.01) CD and higher (P < 0.01) VCR than the LPS group. TA increased (P < 0.01) the level of IL-10 and decreased (P < 0.01) the level of IL-1β. The mRNA expression levels of IL-6, nuclear factor kappa B (NF-κB), TNF-α were up-regulated (P < 0.05) and the levels of IL-10 and inhibitor of NF-κB alpha (IκBα) were down-regulated (P < 0.05) by LPS as compared with the control group. TA down-regulated (P < 0.05) the increased mRNA expression levels of genes caused by LPS, as well as up-regulated (P < 0.05) the levels of IL-10 and IκBα. Furthermore, LPS down-regulated (P < 0.05) and up-regulated (P < 0.05) the protein expression levels of IκBα and NF-κB p65, respectively. TA up-regulated (P < 0.05) the level of IκBα and down-regulated (P < 0.05) the level of NF-κB p65. The conclusion of this study is that TA could exert protective effect on the LPS-induced acute jejunal inflammation of broilers via repressing the activation of NF-κB and the 600 mg/kg is the optimal dose against LPS-induced acute jejunal inflammation of broilers.

Abstract
Emerging nanotechnology leads to success in synthesizing and applying nanoparticles (NPs) using the green-chemistry approach. NPs synthesized using naturally derived materials are a potential alternative to chemical and physical methods because they are simple, cost-effective, eco-friendly, and lower the possibility of hazardous residues being released into the environment. Furthermore, NPs synthesized using the green synthesis approach are stable and biocompatible. However, because natural extracts contain a diverse spectrum of bioactive components, it is difficult to pinpoint the specific component involved in NP formation. Furthermore, the bioactive component contained in the extract changes based on a number of environmental factors; therefore, several studies began with the synthesis of NPs using a pure compound isolated from diverse natural sources. Hence, the present review paper makes an effort to retrospectively analyze the key compounds of the extracts which are responsible for the synthesis of the NPs. The analysis was carried out based on the physicochemical characteristics and biological activities of NPs synthesized from either the extract or the pure compounds. These pure-compound-based NPs were studied for their antimicrobial, antibiofilm, anti-inflammatory, anticancer, and antioxidant properties. In addition, the present review also describes progress in the study of pure compound-based numerous biological activities and the underlying mechanisms of action.

Abstract
Illicium verum Hook f. (star anise) is considered an important species in Traditional Chinese Medicine and is also used in contemporary medicine in East Asian countries. It occurs in natural habitats in southeastern parts of China and Vietnam, and is cultivated in various regions in China. The raw materials—Anisi stellati fructus and Anisi stellati aetheroleum obtained from this species exhibit expectorant and spasmolytic activities. The European Pharmacopoeia (4th edition) indicates that these raw materials have been used in allopathy since 2002. The biological activities of the above-mentioned raw materials are determined by the presence of valuable secondary metabolites such as monoterpenoids, sesquiterpenoids, phenylpropanoids, and flavonoids. Recent pharmacological studies on fruit extracts and the essential oil of this species have confirmed their antibacterial, antifungal, anti-inflammatory, and antioxidant activities and thus their medicinal and cosmetic value. The aim of this review was to examine the progress of phytochemical and pharmacological studies that focused on possible cosmetic applications. In addition to fruit extracts and essential oil, the current consensus on the safety of trans-anethole, which is the main compound of essential oil used in cosmetology, is underlined here.

Abstract
Essential oils (EOs) are increasingly consumed as food supplements. The few published recommended doses available generally lack details both on the methodology used and concentration limits for substances of concern, including genotoxic carcinogens. We propose a tiered approach based on the toxicological evaluation of maximized concentrations of each constituent present in the EO investigated. The genotoxic potential of each constituent is assessed using literature data or QSAR analyses. Genotoxic constituents are evaluated according to the methodology provided in the ICHM7 guideline. A Toxicological Reference Value (TRV) is associated to each non-genotoxic constituent, using one of the following methodologies (decision-tree successive steps): extraction from recognized databases or clinical studies, application of adequate safety factors to NOAELs established in animal studies, read-across analyses and when none was possible, TTC of Cramer classes. An EO recommended dose is considered safe when the safety margin (ratio between TRV and systemic exposure) for all constituents is all at least equal to 1. In conclusion, this methodology has proven to be robust to establish safe recommended doses for EOs used as food supplements, consistent with those publicly available, and avoiding unnecessary dedicated new animal testing.

Abstract
Alkenylbenzenes are naturally occurring secondary plant metabolites, primarily present in different herbs and spices, such as basil or fennel seeds. Thus, alkenylbenzenes, such as safrole, methyleugenol, and estragole, can be found in different foods, whenever these herbs and spices (or extracts thereof) are used for food production. In particular, essential oils or other food products derived from the aforementioned herbs and spices, such as basil-containing pesto or plant food supplements, are often characterized by a high content of alkenylbenzenes. While safrole or methyleugenol are known to be genotoxic and carcinogenic, the toxicological relevance of other alkenylbenzenes (e.g., apiol) regarding human health remains widely unclear. In this review, we will briefly summarize and discuss the current knowledge and the uncertainties impeding a conclusive evaluation of adverse effects to human health possibly resulting from consumption of foods containing alkenylbenzenes, especially focusing on the genotoxic compounds, safrole, methyleugenol, and estragole.

Abstract
In 2015, the Expert Panel of the Flavor and Extract Manufacturers Association (FEMA) initiated a re-evaluation of the safety of over 250 natural flavor complexes (NFCs) used as flavor ingredients, mostly consisting of a variety of essential oils and botanical extracts. This publication, seventh in the series, re-evaluates NFCs with constituent profiles dominated by phenolic derivatives including carvacrol, thymol and related compounds using a constituent-based procedure first published in 2005 and updated in 2018. The procedure is based on the chemical characterization of each NFC as intended for commerce and the estimated intake of the constituent congeneric groups. The procedure applies the threshold of toxicological concern (TTC) concept and evaluates relevant data on absorption, metabolism, genotoxic potential and toxicology of the constituent congeneric groups and the NFC under evaluation. Herein, the FEMA Expert Panel affirmed the generally recognized as safe (GRAS) status of seven phenolic derivative-based NFCs, Origanum Oil (Extractive) (FEMA 2828), Savory Summer Oil (FEMA 3013), Savory Summer Oleoresin (FEMA 3014), Savory Winter Oil (FEMA 3016), Savory Winter Oleoresin (FEMA 3017), Thyme Oil (FEMA 3064) and Thyme White Oil (FEMA 3065) under their conditions of intended use as flavor ingredients.

Croton zehntneri is a plant well adapted to the semi-arid climate of northeastern region of Brazil. The essential oil of C. zehntneri (EOCz) has been described to have several pharmacologic properties, including effect on airflow resistance of in vivo respiratory system. For this reason, we investigated the hypothesis that EOCz and its major constituents, anethole and estragole, have antispasmodic activity on tracheal muscle. In tracheal rings of Wistar rats, maintained in Krebs-Henseleit's solution, EOCz, anethole and estragole inhibited contractions induced by 60mM [K+], ACh (10μM), Ba2+ and Phorbol dibutirate (1 μM). For EOCz, anethole and estragole, the IC50 for inhibition of KCl-induced contractions were 145.8 ± 14.8, 89.9 ± 7.4 and 181.0 ± 23.3 μg/mL, respectively, and for ACh-induced contraction, they were 606.1 ± 122.0, 160.5 ± 33.0 and 358.6 ± 49.2 μg/mL. Pharmacodynamic efficacy was maximal in all cases. These data in Ba2+-induced contraction and the differential IC50 suggested that blockade of Voltage Dependent Calcium Channels (VDCC) is a component of the mechanism of action of the three agents. Evaluation of the direct effect of anethole, on VDCC, showed inhibition of the Ca2+ current through this type of channel. These results show that EOCz and the constituents have antispasmodic activity and the mechanism includes blockade of VDCC channels.

Abstract
trans-Anethole, the major bioactive component of Illicium verum Hook. commonly known as star anise exhibits various pharmacological activities including anti-inflammatory, antimicrobial, insecticidal, and antitumor. Osteosarcoma is an extremely aggressive malignant bone tumor that affects children and young adults and accounts for around 60% of all sarcomas. The study was planned to evaluate the potential of trans-Anethole against Human osteosarcoma cell line MG-63. The antiproliferative activity of trans-Anethole was assessed by MTT assay. trans-Anethole exhibited apoptotic cell death as monitored by confocal/electron microscopy and flow cytometry studies. Modulation of gene expression was studied by Western blot and RT-PCR analysis. The present study revealed that trans-Anethole inhibited osteosarcoma proliferation in a dose-dependent manner with a GI50 value of 60.25 µM and showed pro-apoptotic activity as analyzed by Annexin V-FITC/PI assay. Flow cytometric analysis revealed that trans-Anethole induced cell cycle arrest at the G0/G1 phase with the generation of reactive oxygen species and reduction in mitochondrial membrane potential (ΔΨm). Immunoblotting results showed the increased expression of caspase-9/-3, p53, and decreased expression of Bcl-xL suggesting the involvement of the p53 and mitochondrial intrinsic pathway. This work provides a rationale that trans-Anethole might be considered as a promising chemotherapeutic/nutraceutical agent for the management of osteosarcoma.Highlightstrans-Anethole inhibited cell growth and caused G0/G1 arrest in Human osteosarcoma MG-63 cell line.trans-Anethole led to the loss of mitochondrial membrane permeability along with ROS generation.trans-Anethole upregulates the expression of p53, Caspase-9/-3, and downregulate Bcl-xL expression.

Abstract
In 2015, the Expert Panel of the Flavor and Extract Manufacturers Association (FEMA) initiated a program for the re-evaluation of the safety of over 250 natural flavor complexes (NFCs) used as flavor ingredients. This publication, fifth in the series, evaluates the safety of NFCs containing linalool and/or other characteristic mono- and sesquiterpenoid tertiary alcohols and esters using the safety evaluation procedure published by the FEMA Expert Panel in 2005 and updated in 2018. The procedure relies on a complete chemical characterization of the NFC intended for commerce and organization of the chemical constituents of each NFC into well-defined congeneric groups. The safety of each NFC is evaluated using the well-established and conservative threshold of toxicological concern (TTC) concept in addition to data on absorption, metabolism and toxicology of both the constituent congeneric groups and the NFCs. Sixteen NFCs, derived from the Lavandula, Aniba, Elettaria, Daucus, Salvia, Coriandrum, Ribes, Guaiacum/Bulnesia, Citrus, Pogostemon, Melaleuca and Michelia genera, were affirmed as generally recognized as safe (GRAS) under their conditions of intended use as flavor ingredients based on an evaluation of each NFC and the constituents and congeneric groups therein.

Abstract
We characterized the mechanism underlying star anise (Illicium verum Hook.f) oil (SAO)-mediated antioxidant status during subclinical Escherichia coli (E. coli) challenge. A total of 512 male birds (White Leghorn) at 30 wk of age with similar body weight (2.14 ± 0.02 kg) were randomly divided into 2 groups with 1 group being orally challenged with E. coli (every other day from day 15 to day 27) during the experiment. Each group of birds was then randomly allocated to dietary treatment of SAO supplementation at 0, 200, 400, or 600 mg/kg of basal diet (8 replicate cages during each treatment). The treatments were arranged a 4 × 2 factorial arrangement. The experiment comprised 1 wk of adaptation and 3 wks of data collection. There was no interaction (P > 0.05) between SAO supplementation and E. coli challenge for final body weight and average daily feed intake of birds. However, E. coli challenge resulted in a significant decrease (P < 0.001) in final body weight of birds as compared with unchallenged birds. There were interactions between SAO supplementation and E. coli challenge for the activity of glutathione peroxidase (GSH-Px) and malondialdehyde (MDA) concentration in serum and for the activity of GSH-Px in the liver of birds. Supplementation of SAO enhanced the activities of antioxidant enzymes but decreased the MDA content in the serum and liver of birds, and it also enhanced the expression of genes including superoxide dismutase, catalase, and nuclear factor E2-related factor 2 (Nrf2) in the liver of the birds. Meanwhile, supplementation of SAO can also reduce E. coli challenge-induced oxidative stress in the serum and liver of birds, and the efficacy of SAO in birds during subclinical E. coli challenge is dose-dependent. In conclusion, the enhancement of antioxidant capacity by star anise or its effective compounds is through upregulation of Nrf2 signaling pathway. The optimum supplementation dose of SAO for protecting birds against E. coli challenge is 400 mg/kg.

Abstract
The Flavor and Extract Manufacturers Association (FEMA) Expert Panel relies on the weight of evidence from all available data in the safety evaluation of flavoring substances. This process includes data from genotoxicity studies designed to assess the potential of a chemical agent to react with DNA or otherwise cause changes to DNA, either in vitro or in vivo. The Panel has reviewed a large number of in vitro and in vivo genotoxicity studies during the course of its ongoing safety evaluations of flavorings. The adherence of genotoxicity studies to standardized protocols and guidelines, the biological relevance of the results from those studies, and the human relevance of these studies are all important considerations in assessing whether the results raise specific concerns for genotoxic potential. The Panel evaluates genotoxicity studies not only for evidence of genotoxicity hazard, but also for the probability of risk to the consumer in the context of exposure from their use as flavoring substances. The majority of flavoring substances have given no indication of genotoxic potential in studies evaluated by the FEMA Expert Panel. Examples illustrating the assessment of genotoxicity data for flavoring substances and the consideration of the factors noted above are provided. The weight of evidence approach adopted by the FEMA Expert Panel leads to a rational assessment of risk associated with consumer intake of flavoring substances under the conditions of use.

Abstract
Anethole is a natural anisole derivative that has been widely used in food and daily chemical industries, agricultural applications and the traditional medicine. It is closely related to aspects of daily life, and humans can easily be exposed to it. Although the reproductive toxicity of anethole was shown in the rat, its effect on human reproduction remains unknown. In this study, we examined the effect of anethole on human sperm in vitro. Different anethole doses (0.1, 1, 10, and 100 μM) were applied to ejaculated human sperm. Fertilization-essential functions, as well as the intracellular calcium concentration ([Ca2+]i) and tyrosine phosphorylation, two vital factors for regulating sperm function, were measured. The results indicated that 10 and 100 μM anethole significantly reduced the motility, hyperactivation, and penetration ability of human sperm (P < 0.05) and inhibited the increase in human sperm functions induced by progesterone, a hormone essential for sperm function activation. Additionally, 10 and 100 μM anethole decreased both basal and progesterone-increased tyrosine phosphorylation, [Ca2+]i, and the current of CATSPER, a cation channel of sperm predominant for Ca2+ influx. These results suggest that anethole inhibits human sperm functions by reducing sperm [Ca2+]i through CATSPER and suppressing tyrosine phosphorylation in vitro, raising the fact that the caution is needed when overtaking anethole.

Abstract
Aim: The aim of this study was to evaluate the effect of subinhibitory concentrations of trans-anethole on antibacterial and antibiofilm properties of mupirocin against mupirocin-resistant Staphylococcus aureus strains. Methods: Following parameters were examined: isolates susceptibility to antibiotics, minimum inhibitory concentration (MIC) of trans-anethole, antibacterial activity of mupirocin/trans-anethole combination, detection of ileS2 gene, genotypic relativity of isolates using pulsed-field gel electrophoresis method, and the influence of mupirocin/trans-anethole combination on S. aureus biofilm formation. Results: Our study revealed that trans-anethole combined with mupirocin increased the growth inhibition zone diameter around the mupirocin disk, independently on S. aureus strains susceptibility to this antibiotic. Moreover, combination of subinhibitory (MIC50) concentration of mupirocin and trans-anethole significantly decreased biofilm biomass. Conclusions: trans-Anethole appeared efficient in increasing susceptibility to mupirocin and decreasing biofilm formation in S. aureus strains used in this study. Reduction of biofilm formation can potentially protect against S. aureus recolonization. Moreover, use of trans-anethole in combination with mupirocin can increase the mupirocin activity against methicillin-resistant and mupirocin-resistant S. aureus strains.

Abstract
Intimately coupled photocatalysis and biodegradation (ICPB) is a novel wastewater treatment technique that has potential applications in refractory degradation. This paper reports a synergistic degradation protocol that allowing the transfer of photoelectrons between photocatalysts and microbes without supplementary electron donors or improving the loading rate of the photocatalysts. As a result, a degradation rate of ∼94% was sustained for 400 h in a perturbation setup with a hydraulic retention time of 4.0 h. We achieved the degradation of β-apo-oxytetracycline, a stable antimicrobial intermediate compound (half-life of 270 d in soil interstitial water), within 10 min, and no accumulation was observed. Moreover, the required loading rate of the photocatalyst was dramatically reduced to 18.3% compared to previous reports which mentioned much higher rates. The results of our study provided a new strategy to improve the degradation efficiency of oxytetracycline and give new insight into the degradation mechanism of the bio-photocatalytic degradation system.

Abstract
Anethole is an ingredient in many flavours, fragrances and pharmaceutical formulations. To reduce the dependence of its supply on natural oils, a green route for anethole synthesis was designed on the basis of Meerwein-Pondorf-Verley (MPV) reduction and dehydration of 4'-methoxypropiophenone. The one-pot cascade reactions were heterogeneously catalysed by dual-functional Zr-MSU-3, a predominantly Lewis-acidic catalyst with a Si/Zr ratio of 10 and pores with sizes in the range of 3.2-4.2 nm. The use of 2-pentanol as solvent and hydrogen donor for the MPV reduction was advantageous, as its high boiling point enhances the rate of the reactions, especially the dehydration of the MPV product, 1-(4-methoxyphenyl)-propan-1-ol. This dispenses with the need for a strong acid catalyst that could result in by-products of acid-catalysed reactions. Anethole yields of 91 % with a trans/cis isomer ratio of about 92:8, similar to that of natural anethole, were obtained. In comparison, microporous Zr-beta (Si/Zr 12.5) gave lower activity owing to pore-size constraints. Hence, through design of the reactions and catalyst, 4'-methoxypropiophenone can be efficiently converted to anethole in a sustainable and green manner.

Abstract
The safety assessment of a flavour substance examines several factors, including metabolic and physiological disposition data. The present article provides an overview of the metabolism and disposition of flavour substances by identifying general applicable principles of metabolism to illustrate how information on metabolic fate is taken into account in their safety evaluation. The metabolism of the majority of flavour substances involves a series both of enzymatic and non-enzymatic biotransformation that often results in products that are more hydrophilic and more readily excretable than their precursors. Flavours can undergo metabolic reactions, such as oxidation, reduction, or hydrolysis that alter a functional group relative to the parent compound. The altered functional group may serve as a reaction site for a subsequent metabolic transformation. Metabolic intermediates undergo conjugation with an endogenous agent such as glucuronic acid, sulphate, glutathione, amino acids, or acetate. Such conjugates are typically readily excreted through the kidneys and liver. This paper summarizes the types of metabolic reactions that have been documented for flavour substances that are added to the human food chain, the methodologies available for metabolic studies, and the factors that affect the metabolic fate of a flavour substance.

Abstract
Chronic exposure of inorganic arsenic compounds is responsible for the manifestation of various tumours as well as other diseases. The principal mechanism behind arsenic toxicity is the induction of a strong oxidative stress with production of free radicals in cells. The present study was aimed to explore the shielding effect of anethole against oxidative damage induced by arsenic in cultured human peripheral blood lymphocytes and the effect of GSTO1 polymorphism. Sister chromatid exchange (SCE) frequency, comet tail moment and lipid peroxidation levels were used as biomarkers to assess the oxidative damage. Heparinised venous blood was collected from healthy individuals and treated with sodium arsenite (50 µM) in the presence of anethole (25 and 50 µM) for the analysis of shielding effect of anethole. For the genotyping of GSTO1, PCR RFLP method was adopted. A significant dose-dependent increase in the frequency of SCEs, tail moment and lipid peroxidation levels, was observed when lymphocytes were treated with sodium arsenite. Anethole in combination with sodium arsenite has shown a dose-dependent significant decrease in the frequency of SCEs, tail moment and lipid peroxidation levels. Genetic polymorphism of GSTO1 was found to effect individual susceptibility towards arsenic-mediated genotoxicity and was found insignificant when antigenotoxic effect of anethole was considered. GSTO1 mutant genotypes were found to have significant higher genotoxicity of sodium arsenite as compared to wild-type genotype. The results of the present study suggest ameliorative effects of anethole against arsenic-mediated genotoxic damage in cultured human peripheral blood lymphocytes. A significant effect of GSTO1 polymorphism was observed on genotoxicity of sodium arsenite.

Abstract
OBJECTIVE AND AIM Alcohol-related hepatotoxicity is not only caused by excessive alcohol consumption but also caused and even accelerated by hepatotoxic ingredients other than ethanol. Concentrations of hepatotoxic substances might be significantly high, particularly in illegally produced home-made alcohols. In this study we aim to analyze the hepatotoxic effects of a home-made alcohol traditionally called "bogma raki" in Turkey. MATERIALS AND METHOD Fifty Wistar albino male rats were used. Five groups were randomly formed with ten animals in each. Besides laboratory diets, groups were fed as follows: Group 1 (control group) distilled water; Group 2 bogma raki with distilled water (%44 (v/v), 9.2 ml/kg/day); Group 3 bogma raki with distilled water (%44 (v/v), 9.2 ml/kg/day)+walnut (10 g/kg/day); Group 4 whisky with distilled water (%40 (v/v), 9.2 ml/kg/day); Group 5 distilled water + walnut (10 g/kg/day), for 28 days. The toxicological analysis of The spirits were analyzed using Hewlett-Packard (Palo Alto, CA) GC/MS system with HP 6890 gas chromatograph, an HP 5972 mass selective detector (MSD) and an HP 6890 automatic liquid sampler GC/MS; the pressure of the carrier gas helium was 6.0 bar and the split value with a ratio of 1:100. The injection unit temperature set to 250 °C and MS quadrupole temperature set to 280 °C. The MS quadrupole detector ionization energy set to 70 eV. The initial column temperature was 60 °C (for 4 min) programmed by 6 °C/min to final temperature 160 °C and kept for 8 min at 160 °C. Utilized whisky and bogma raki samples were analyzed for the amounts of trans-anethole, ethanol, methanol, 1-propanolol, butanol, 2-butanol, 2-methyl-1-propanolol (isobutanol) and 3-methylbutanol (isoamyl alcohol). Histopathological changes in liver tissues were graded as follows; normal = 0 (<10%), mild = 1 (10%-40%), moderate = 2 (40%-70%), severe = 3 (above 70%). RESULTS Chemical composition of illegally produced raki sample (%v/v) was as follows: trans-anethole %1.93, ethanol %95.70, 2-methyl-1-propanolol (isobutanol) %0.19, asetic acid %0.25, 3-methylbutanol (isoamyl alcohol) %0.77, and others %1.16. Chemical composition of commercial whisky sample (%v/v) was as follows: ethanol %97.72, 2-methyl-1-propanolol (isobutanol) %0.57, asetic acid %0.23, 3-methylbutanol (isoamyl alcohol) %1.28, and others %0.2. No traces of trans-anethole were detected in whisky. Normal liver morphology was recorded in control and walnut groups. However, bogma raki caused significant congestion and inflammatory cell infiltration compared to control and walnut group. On the other hand, whisky administration caused mild degeneration including inflammation in a limited area. CONCLUSION Obtained findings suggest that trans-anethole containing alcoholic beverages are more hepatotoxic compared to commercial alcoholic beverages.

Abstract
In recent decades, the use of herbal medicines and food products has been widely embraced in many developed countries. These products are generally highly accepted by consumers who often believe that "natural" equals "safe". This is, however, an oversimplification because several botanicals have been found to contain toxic compounds in concentrations harmful to human health. Acutely toxic plants are in most cases already recognised as dangerous as a result of their traditional use, but plants with subacute and chronic toxicity are difficult or even impossible to detect by traditional use or by clinical research studies. In this review, we systematically address major issues including the carcinogenicity, teratogenicity and endocrine-disrupting effects associated with the use of herbal preparations with a strong focus on plant species that either grow natively or are cultivated in Europe. The basic information regarding the molecular mechanisms of the individual subtypes of plant-induced non-acute toxicity is given, which is followed by a discussion of the pathophysiological and clinical characteristics. We describe the genotoxic and carcinogenic effects of alkenylbenzenes, pyrrolizidine alkaloids and bracken fern ptaquiloside, the teratogenicity issues regarding anthraquinone glycosides and specific alkaloids, and discuss the human health concerns regarding the phytoestrogens and licorice consumption in detail.
