Abstract
Resorcinolic lipids are described as potential examples of selective chemotherapeutic adjuvants that can enhance the effects of cyclophosphamide (CYC) while promoting cell death without causing DNA damage. Therefore, the current study attempted to describe how the resorcinolic lipid methyl 3,5-dimethoxy-2-octanoylbenzoate (AMS35BB) interacted with DNA (DNA docking) and how this compound affected genetic toxicology models and other biological characteristics when combined with CYC. We observed that AMS35BB, used alone (7.5 and 10 mg/kg), increases the frequency of genomic damage (comet assay) but not chromosomal damage (micronuclei assay), lowers phagocytosis, and promotes cell death in Swiss male mice. When used in association with CYC, AMS35BB can reduce the risk of genomic damage by up to 33.8% as well as chromosomal damage, splenic phagocytosis, cell death, and lymphocyte frequency. Molecular docking showed that AMS35BB had a higher affinity than the active metabolite of CYC for binding to the DNA double helix major groove. As a result, AMS35BB has the potential to be both an adjuvant when used in association with CYC and a therapeutic candidate for the development of a selective chemotherapeutic drug.

Abstract
Hemp bioproducts hold great promise as valuable materials for nutraceutical and pharmaceutical applications due to their diverse bioactive compounds and potential health benefits. In line with this interest and in an attempt to valorize the Lazio Region crops, this present study investigated chemically characterized hydroalcoholic and organic extracts, obtained from the inflorescences of locally cultivated Felina 32, USO 31, Ferimon and Fedora 17 hemp varieties. In order to highlight the possible chemopreventive power of the tested samples, a bioactivity screening was performed, which included studying the antimutagenic activity, radical scavenging power, cytotoxicity in human hepatoma HepG2 cells, leakage of lactate dehydrogenase (LDH) and modulation of the oxidative stress parameters and glucose-6-phosphate dehydrogenase (G6PDH) involved in the regulation of the cell transformation and cancer proliferation. Tolerability studies in noncancerous H69 cholangiocytes were performed, too. The organic extracts showed moderate to strong antimutagenic activities and a marked cytotoxicity in the HepG2 cells, associated with an increased oxidative stress and LDH release, and to a G6PDH modulation. The hydroalcoholic extracts mainly exhibited radical scavenging properties with weak or null activities in the other assays. The extracts were usually well-tolerated in H69 cells, except for the highest concentrations which impaired cell viability, likely due to an increased oxidative stress. The obtained results suggest a possibility in the inflorescences from the Felina 32, USO 31, Ferimon and Fedora 17 hemp varieties as source of bioactive compounds endowed with genoprotective and chemopreventive properties that could be harnessed as preventive or adjuvant healing strategies.

Abstract
Cancer incidence is increasing, and the drugs are not very selective. These drugs cause adverse effects, and the cells become resistant. Therefore, new drugs are needed. Here, we evaluated the effects of ZIM, a candidate for chemotherapy, and 4-AA alone and in association with commercial chemotherapeutic agents. Subsequently, the results of ZIM and 4-AA were compared. Male Swiss mice were treated with doses of 12, 24, or 48 mg/kg ZIM or 4-AA alone or in association with cisplatin (6 mg/kg), doxorubicin (16 mg/kg), and cyclophosphamide (100 mg/kg). Biometric parameters, DNA damage (comet and micronuclei), cell death, and splenic phagocytosis were evaluated. DNA docking was also performed to confirm the possible interactions of ZIM and 4-AA with DNA. 4-AA has been shown to have low genotoxic potential, increase the frequency of cell death, and activate phagocytosis. ZIM causes genomic and chromosomal damage in addition to causing cell death and activating phagocytosis. In association with chemotherapeutical agents, both 4-AA and ZIM have a chemopreventive effect and, therefore, reduce the frequency of DNA damage, cell death, and splenic phagocytosis. The association of 4-AA and ZIM with commercial chemotherapeutic agents increased the frequency of lymphocytes compared to chemotherapeutic agents alone. Molecular docking demonstrated that ZIM has more affinity for DNA than 4-AA and its precursors (1 and 2). This was confirmed by the lower interaction energy of the complex (-119.83 kcal/mol). ZIM can break the DNA molecule and, therefore, its chemotherapeutic effect can be related to DNA damage. It is considered that ZIM has chemotherapeutic potential. However, it should not be used in combination with cisplatin, doxorubicin, and cyclophosphamide as it reduces the effects of these drugs.

Abstract
Essential oils (EOs) and their individual volatile organic constituents have been an inherent part of our civilization for thousands of years. They are widely used as fragrances in perfumes and cosmetics and contribute to a healthy diet, but also act as active ingredients of pharmaceutical products. Their antibacterial, antiviral, and anti-inflammatory properties have qualified EOs early on for both, the causal and symptomatic therapy of a number of diseases, but also for prevention. Obtained from natural, mostly plant materials, EOs constitute a typical example of a multicomponent mixture (more than one constituent substances, MOCS) with up to several hundreds of individual compounds, which in a sophisticated composition make up the property of a particular complete EO. The integrative use of EOs as MOCS will play a major role in human and veterinary medicine now and in the future and is already widely used in some cases, e.g., in aromatherapy for the treatment of psychosomatic complaints, for inhalation in the treatment of respiratory diseases, or topically administered to manage adverse skin diseases. The diversity of molecules with different functionalities exhibits a broad range of multiple physical and chemical properties, which are the base of their multi-target activity as opposed to single isolated compounds. Whether and how such a broad-spectrum effect is reflected in natural mixtures and which kind of pharmacological potential they provide will be considered in the context of ONE Health in more detail in this review.

Abstract
Royal jelly (RJ) is a creamy white-yellow liquid that is secreted by the mandibular and hypopharyngeal glands of bees to nourish the larvae. RJ has gained increasing interest in recent years owing to its antioxidant potential. However, little is known about adequate RJ dosing and its effects on genetic material. Thus, the aim of this study was to evaluate the in vivo effects of RJ on genotoxicity and mutagenicity induced by the alkylating agent methyl methanesulfonate (MMS). In this study, 3-month-old Swiss albino male mice (N = 66) were divided into 11 groups for experimentation. Experiments were performed by administering lyophilized RJ (150 mg/kg, 300 mg/kg, and 1000 mg/kg) or water via gavage as pre- and posttreatment processes with the alkylating agent MMS. After treatment, blood samples were collected from the mice via an incision at the end of the tail to conduct comet assays at times of 24 h and 48 h posttreatment. The mice were then euthanized to remove the bone marrow for a micronucleus test. Overall, regardless of dose, RJ did not exhibit genotoxic, mutagenic activity and the administration of high doses, mainly in the form of posttreatment, presented antigenotoxic and antimutagenic actions. Further, a dose-response correlation was observed in the RJ posttreatment groups. These results demonstrate that RJ administration was effective in reversing the damage caused by the alkylating agent MMS.

Abstract
Myricitrin (MYR), a flavonol consumed in the leaves and fruits of plants of the Myrtaceae family, presents anti-proliferative, anti-inflammatory, anti-diabetic, and antioxidant properties in humans. However, there are few studies regarding the cyto-genotoxicity and the chemopreventive potential of MYR. Using the in vitro Micronucleus test, the cytostasis, mutagenicity, and modulatory effect of MYR in CHO-K1 cells were assessed. The concentrations of 39 and 78 µg/mL (p < 0.001.) of MYR decrease the cytokinesis-block proliferation index (CBPI) in the short exposure treatment (4 h), while in the extended treatment (24 h), concentrations of 4.8, 9.7, 19.5, 39 and 78 µg/mL (p < 0.001.) decreased the CBPI. MYR associated with oxaliplatin decreased CBPI at all tested concentrations in the pre-(p < 0.001) and post-treatments (p < 0.001), but there was no decrease when associated with bleomycin. As for chromosome instability, MYR did not increase the frequency of micronuclei (MNi), nucleoplasmic bridges (NPBs), or nuclear buds (NBUDs) in the 4 h exposure time, however, in the 24 h treatment, MYR increased the frequency of MNi and NPBs at concentration 19.5 µg/mL (p < 0.001). As for the modulatory effect, MYR associated with bleomycin decreased the frequency of MNi, NPBs, and NBUDs at all concentrations in the pretreatment (MNi and NPBs p < 0.001, NBUDs p < 0.05) and simultaneously (MNi, NPBs and NBUDs p < 0.001). When associated with oxaliplatin, the simultaneous treatment decreased the frequency of MNi (p < 0.001) and NBUDs (p < 0.01) at all concentrations, however, in the post-treatment, MYR increased MNi (p < 0.001) and NPBs p < 0.05) in CHO-K1 cells, when compared to oxaliplatin alone. The results demonstrated that MYR could modulate the mutagenic and cytostatic actions of bleomycin and oxaliplatin, demonstrating distinct behaviors, depending on the mechanism of action of the chemotherapeutic agent.

Abstract
INTRODUCTION Plants can be sources of photoprotective/antigenotoxic compounds that prevent cellular mutations involved in skin cancer and aging by regulating UV-induced mutability. PURPOSE The study was aimed at investigating the sunscreen properties of plants growing in Colombia. MATERIALS AND METHODS Ultraviolet (UV) radiation-absorption capability of different plant extracts was examined. In vitro photoprotection efficacies were evaluated using in vitro indices such as sun protection factor (SPFin vitro) and critical wavelength (λc). Pearson correlation analysis was used to examine the relationship between SPFin vitro and complementary UVB- antigenotoxicity estimates (%GI) based on the SOS Chromotest database. The cytotoxicity in human fibroblasts was studied using the trypan blue exclusion assay. Major compounds of promising plant extracts were determined by gas chromatography coupled to mass spectrometry (GC/MS). RESULTS We showed that plant extracts have sunscreen properties against UVB, whereas broad-spectrum radiation protection efficacy was poor. SPFin vitro and %GI were correlated (R = 0.71, p < .0001) for the plant extracts under study. Three extracts obtained from Achyrocline satureioides, Chromolaena pellia, and Lippia origanoides species resulted to possess high protection efficacy and relatively low cytotoxicity in human fibroblasts. These plant extracts contained major compounds such as α-pinene, trans-β-caryophyllene, γ-muurolene, γ-cadinene and caryophyllene oxide in A. Satureioides extract, trans-β-caryophyllene, caryophyllene oxide, squalene and α-amyrin in C. pellia extract, and p-cymene, carvacrol, trans-β-caryophyllene and pinocembrin in L. origanoides extract. CONCLUSIONS Plants growing in Colombia contain compounds that can be useful for potential sunscreens. SPFin vitro and %GI estimates were correlated, but %GI estimates were more sensitive to detecting activity at lower plant extract concentrations. Our results supported the need to use DNA damage detection assays as a complement to photoprotection efficacy measurement.

Abstract
BACKGROUND Colorectal cancer is a highly prevalent disease, requiring effective strategies for prevention and treatment. The present research aimed to formulate a natural fiber-rich food product (NFRFP) and to evaluate its safety, toxicogenetics, and effects on aberrant crypt foci induced by 1,2-dimethyl-hydrazine in a preclinical model. METHODS A total of 78 male Wistar rats were distributed in six experimental groups: negative control, positive control (1,2-Dimethylhydrazine-40 mg/Kg), and four groups fed with 10% NFRFP: NFRFP, pre-treatment protocol, simultaneous treatment, and post-treatment protocol. RESULTS The NFRFP was shown to be a good source of fibers and did not change biometric, biochemical, hematological, and inflammatory parameters, and did not induce signs of toxicity and genotoxicity/carcinogenicity. NFRFP exhibited a chemopreventive effect, in all protocols, with damage reduction (% DR) of 75% in the comet test. NFRFP reduced the incidence of aberrant crypt outbreaks by 49.36% in the post-treatment protocol. CONCLUSIONS The results suggest the applicability of NFRFP in the human diet due to potential production at an industrial scale and easy technological application in different products, since it could be incorporated in food without altering or causing small changes in final product sensory characteristics.

[PMID: 33676582 PMCID: PMC7937315 DOI: 10.1186/s41021-021-00180-8] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/12/2021] [Accepted: 02/18/2021] [Indexed: 01/14/2023] Open
Abstract
Before 'cancer interception' was first advocated, 'interceptor molecules' had been conceived as a sub-category of preventive agents that interfered with the earliest initiation steps in carcinogenesis. Three decades ago, a seminal review cataloged over fifty synthetic agents and natural products that were known or putative interceptor molecules. Chlorophylls and their derivatives garnered much interest based on the potent antimutagenic activity in the Salmonella assay, and the subsequent mechanistic work that provided proof-of-concept for direct molecular complexes with planar aromatic carcinogens. As the 'interceptor molecule' hypothesis evolved, mechanistic experiments and preclinical studies supported the view that chlorophylls can interact with environmental heterocyclic amines, aflatoxins, and polycyclic aromatic hydrocarbons to limit their uptake and bioavailability in vivo. Support also came from human translational studies involving ultralow dose detection in healthy volunteers, as well as intervention in at-risk subjects. Antimutagenic and antigenotoxic effects of natural and synthetic chlorophylls against small alkylating agents also highlighted the fact that non-interceptor mechanisms existed. This gave impetus to investigations broadly related to free radical scavenging, anti-inflammatory effects, immune modulation and photodynamic therapy. Therapeutic aspects of chlorophylls also were investigated, with evidence for cell cycle arrest and apoptosis in human cancer cells. As the science has evolved, new mechanistic leads continue to support the use and development of chlorophylls and their porphyrin derivatives for cancer interception, beyond the initial interest as interceptor molecules.

Abstract
OBJECTIVE The present study aims to evaluate the antioxidant effect of beta glucan on oxidative DNA damage by comet assay. METHODS A total of 19 adult females and males diagnosed with stage 3-4 colorectal cancer and a control group of 20 age-matched healthy subjects were enrolled in the study. Blood samples of the participants were analyzed using Comet Assay for the parameters of DNA damage. RESULTS Significantly increased DNA damage was observed in patients versus control group as indicated by greater values of tail moment, tail percent DNA and tail length. Following incubation with β-glucan, a substantial reduction was found in the aforementioned parameters of DNA damage. Comet assay revealed significant levels of endogenous DNA damage in patients as shown by remarkable increases in the tail moment, the percentage of DNA in the tail and the tail length values, in comparison with the control group. Following treatment of fresh whole blood with β-glucan incubation, DNA damages were significantly reduced but lower values were observed after β-glucan incubation in the patient group versus control group. CONCLUSION β-Glucan was found to reduce DNA damage substantially in colorectal cancer patients and show antimutagenic effects. Our results suggested that dietary β-glucan intake might be important in the genesis of colorectal cancer tumors.

Abstract
Purpose To evaluate red propolis, gum arabic and L-lysine activity on colorectal
preneoplastic lesions induced by azoxymethane (AOM). Methods The study featured 4 control groups (I-IV) and 4 experimental groups
(V-VIII), totaling 48 rats. Once a week for 2 weeks, animals on control
groups received saline, while animals in experimental groups received
azoxymethane (15 mg/kg i.p.). The follow up along 16 weeks included daily
oral gavage to administer water (I and V), L-lysine (150 mg/kg)(II and VI),
própolis (100mg/5ml/kg)(III and VII), or gum arabic (5ml/kg)(IV and VIII).
Was performed surgery on the animals in the end of this time in order to
collect blood for biological assays (TBARS, GSH), followed by their
sacrifice to tissue extract. Results Oxidative stress (TBARS) and the number of aberrant crypt foci (ACF) in
distal colon were lower using própolis (p<0.01 for both parameters). Gum
arabic reduced preneoplastic lesions (ACF ≤ 4 crypts) on distal colon and on
the entire colon (p<0.05). Conclusions Red propolis reduced AOM-induced oxidative stress (TBARS) and total number
of ACF in the distal colon. L-lysine neither protected against nor enhanced
AOM-induced ACF. Gum arabic reduced the number of ACF.

Abstract
Essential oils are secondary metabolites with a key-role in plants protection, consisting primarily of terpenes with a volatile nature and a diverse array of chemical structures. Essential oils exhibit a wide range of bioactivities, especially antimicrobial activity, and have long been utilized for treating various human ailments and diseases. Cancer cell prevention and cytotoxicity are exhibited through a wide range of mechanisms of action, with more recent research focusing on synergistic and antagonistic activity between specific essential oils major and minor components. Essential oils have been shown to possess cancer cell targeting activity and are able to increase the efficacy of commonly used chemotherapy drugs including paclitaxel and docetaxel, having also shown proimmune functions when administered to the cancer patient. The present review represents a state-of-the-art review of the research behind the application of EOs as anticancer agents both in vitro and in vivo. Cancer cell target specificity and the use of EOs in combination with conventional chemotherapeutic strategies are also explored.

Abstract
In the present study, the ability of the natural sesquiterpene β-caryophyllene (CRY) and its metabolite β-caryophyllene oxide (CRYO) to inhibit the genotoxicity of a condensate of cigarette smoke (CSC) was evaluated both in bacterial and mammalian cells. Also, the inhibition of the CSC-mediated STAT3 phosphorylation and intracellular oxidative stress was evaluated as potential chemopreventive mechanism. Under our experimental conditions, both the sesquiterpenes exhibited antimutagenic properties, being CRY the most potent compound. The antimutagenicity was highlighted in all experimental protocols, being particularly strong in the co- and post-treatments. The test substances also reduced the micronuclei frequency induced by CSC, with a major effectiveness of CRY. CRY was also able to reduce the CSC-mediated increase of the Y705- pSTAT3 levels, in spite of a lacking effect of CRYO. Furthermore, the sesquiterpenes CRY and CRYO displayed a moderate antioxidant activity, with a 25 % and 40 % inhibition of the ROS-levels increased by CSC, respectively. On the basis of these results, CRY seems to be a multi-target chemopreventive agent, although the genoprotective and antioxidant effects of CRYO suggest that both compounds deserve to be deeply investigated for a possible application in the prevention and treatment of different smoke-related ailments.

Abstract
Chemotherapy is one of the major approaches for the treatment of cancer. Therefore,
the development of new chemotherapy drugs is an important aspect of medicinal
chemistry. Chemotherapeutic agents include isocoumarins, which are privileged
structures with potential antitumoral activity. Herein, a new 3-substituted
isocoumarin was synthesized from 2-iodo-3,5-dimethoxy-benzoic acid and oct-1-yne in a
cross-coupling Sonogashira reaction followed by a copper iodide-catalyzed
intramolecular cyclization as key step using MeOH/Et3N as the solvent
system. The present study also evaluated the leukometry, phagocytic activity,
genotoxic potential and cell death induction of three different doses (5 mg/kg, 10
mg/kg and 20 mg/kg) of this newly synthesized isocoumarin, alone and in combination
with the commercial chemotherapeutic agents cyclophosphamide (100 mg/kg) and
cisplatin (6 mg/kg) in male Swiss mice. The results suggest that the isocoumarin has
genotoxicity and causes cell death. Noteworthy, this new compound can increase
splenic phagocytosis and lymphocyte frequency, which are related to immunomodulatory
activity. When combined with either cyclophosphamide or cisplatin, chemopreventive
activity led to a reduction in the effects of both chemotherapeutic drugs. Thus, the
new isocoumarin is not a candidate for chemotherapeutic adjuvant in treatments using
cyclophosphamide or cisplatin. Nevertheless, the compound itself is an important
prototype for the development of new antitumor drugs.

Abstract
Herbal products contain a variety of compounds which may be useful in protecting against cellular damage caused by mutagens. Orthosiphon stamineus (O.s) also known as Cat whiskers. The herb has been shown anti-oxidative properties and can modulate key cellular proteins that have cytoprotective effect. The study aimed to evaluate the effects of different doses (250, 500 and 1000 mg kg-1) of 50% ethanol extract of O.s (Et. O.s) on micro-nucleated polychromatic erythrocytes (MNPCE), Polychromatic to normachromatic erythrocytes ratio (PCE/NCE), Mitotic index (MI), and Chromosomal aberration (CA) in Bab/c mice. Moreover, these parameters were used to evaluate the anti-genotoxic and clastogenic potencies of (Et. O.s) against mitomycin c (MMC) that interact with biological molecules and induce genotoxic and clastogenic disorders in non-tumor cells. MMC (4 mg kg-1) was injected intraperitoneally (i.p.) to the mice before and after treatment with three different doses of (Et. O.s). The results indicated that the extract at different doses did not show significant (p ≥ 0.05) differences in (MNPCE), (PCE/NCE) ratios, and (CA) values. The higher doses sowed high (MI) values compared with untreated control group. MMC showed significant increase (p ≤ 0.001) in (MNPCE), (CA) and reduce (PCE/NCE) and (MI) values compared with untreated control group. Treatment with (Et. O.s) at different doses before and after MMC injection showed to modulate MNPCE, PCE/NCE ratios, CA and MI values in mice bone marrow cells suggesting genoprotective potential of this plant extract.

Abstract
Bioactive natural products play critical roles in modern drug development, especially anticancer agents. It has been widely reported that various pharmacological activities of such compounds are related to their antioxidant properties. Vanillin is a natural substance widely found in many plant species and often used in beverages, foods, cosmetics, and pharmaceutical products. Antioxidant and anticancer potential have been described for this compound. Considering the importance of vanillin in the area of human health and food and pharmaceuticals sectors, in this review, we discuss the role of vanillin on redox status and its potential contribution to the prevention and the treatment of cancer.

Abstract
Cigarette filters pose a serious litter and toxic waste disposal problem, because of their not biodegradability and to the leaching of toxins in the environment. Therefore, cigarette butts need to be manipulated as special waste, with potential risks to human health and environment. In the present study, the genotoxic potential of a methanol extract from commonly discharged cigarette butts (CBE) was evaluated in the bacterial reverse mutation assay on Salmonella typhimurium TA98 and TA100 and Escherichia coli WP2uvrA strains, both in the absence and presence of the S9 exogenous metabolic activator. Furthermore, the ability of the natural sesquiterpenes β-caryophyllene (CRY) and β-caryophyllene oxide (CRYO) to inhibit the mutagenicity of CBE was studied as a possible preventive strategy. In order to identify the potential antimutagenic mechanisms, three different protocols (pretreatment, cotreatment, and posttreatment) were applied. CBE showed to increase the number of revertant colonies in all the strains tested in presence of S9, so resulting mutagenic. In the antimutagenicity assay, both CRY and CRYO significantly reduced the revertant colonies induced by CBE, although with different potency and specificity. For both sesquiterpenes, the antimutagenicity was strong in all experimental conditions, except for the cotreatment of CRY with CBE in WP2uvrA, which produced a moderate inhibition. Both desmutagenic and bioantimutagenic mechanisms seem to be involved in the antimutagenicity of the test substances. Taking into account the potential genotoxicity of cigarette butts, CRY and CRYO appear as possible further candidates as environmental decontaminants against this hazardous waste. © 2015 Wiley Periodicals, Inc.

Abstract
Acute renal failure (ARF) is an extremely important public health issue in need of
novel therapies. The present study aimed to evaluate the capacity of mesenchymal stem
cell (MSC) therapy to promote the improvement and recovery of renal function in a
preclinical model. Wistar rats were used as the experimental model, and our results
show that cisplatin (5mg/kg) can efficiently induce ARF, as measured by changes in
biochemical (urea and creatinine) and histological parameters. MSC therapy performed
24h after the administration of chemotherapy resulted in normalized plasma urea and
creatinine levels 30 and 45d after the onset of kidney disease. Furthermore, MSC
therapy significantly reduced histological changes (intratubular cast formation in
protein overload nephropathy and tubular hydropic degeneration) in this ARF model.
Thus, considering that current therapies for ARF are merely palliative and that MSC
therapy can promote the improvement and recovery of renal function in this model
system, we suggest that innovative/alternative therapies involving MSCs should be
considered for clinical studies in humans to treat ARF.

Cardanol: toxicogenetic assessment and its effects when combined with cyclophosphamide. Genet Mol Biol 2016; 39:279-89. [PMID: 27303909 PMCID: PMC4910563 DOI: 10.1590/1678-4685-gmb-2015-0170] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/13/2015] [Accepted: 12/20/2015] [Indexed: 01/17/2023] Open
Abstract
Cardanol is an effective antioxidant and is a compound with antimutagenic and
antitumoral activity. Here, we evaluated the genotoxic and mutagenic potential of
saturated side chain cardanol and its effects in combination with cyclophosphamide in
preventing DNA damage, apoptosis, and immunomodulation. Swiss mice were treated with
cardanol (2.5, 5 and 10 mg/kg) alone or in combination with cyclophosphamide (100
mg/kg). The results showed that cardanol is an effective chemopreventive compound,
with damage reduction percentages that ranged from 18.9 to 31.76% in the comet assay
and from 45 to 97% in the micronucleus assay. Moreover, cardanol has the ability to
reduce the frequency of apoptosis induced by cyclophosphamide. The compound did not
show immunomodulatory activity. A final interpretation of the data showed that,
despite its chemoprotective capacity, cardanol has a tendency to induce DNA damage.
Hence, caution is needed if this compound is used as a chemopreventive agent. Also,
this compound is likely not suitable as an adjuvant in chemotherapy treatments that
use cyclophosphamide.

Abstract
Potential prophylactic attributes in terms of antimutagenicity, antioxidant, and radioprotective properties were evaluated for 8 common apple cultivars namely "Fuji," "Golden Delicious," "Granny Smith," "Ambri Kashmiri," "Kinnaur," "Red Delicious," "Royal Gala," and "Shimla," where cultivar based significant variation was observed. Cv. "Granny Smith" displayed significantly higher and broad spectrum antimutagenicity in Escherichia coli rpoB based rifampicin resistance (Rif(R) ) assay, whereas, "Ambri Kashmiri," "Royal Gala," and "Shimla" showed lower antimutagenicity. Cultivars "Ambri Kashmiri," "Kinnaur," and "Red Delicious" exhibited strong antioxidant activity than cv. "Granny Smith" as assayed by radical scavenging, reducing potential and radioprotective property assays. The antioxidant and radioprotective properties were found to be better correlated than antimutagenicity. Suppression of error-prone DNA repair pathway (such as E. coli SOS response) was found to be one of the possible mechanisms contributing to its antimutagenicity. Phenolic extract of "Granny Smithˮ showing higher antimutagenicity was HPLC purified and the bioactive fraction (tR 35.4 min) contributing maximally (∼80%) to the observed antimutagenicity was identified as procyanidin dimer (PD) by ESI-MS/MS. The above observed antimutagenicity in bacterial assay system was well reproduced in Thymidine Kinase Mutation (TKM) assay performed using human lymphoblast cell line (TK6(+/-) ) cell line making the findings more prophylactically relevant.

Abstract
CONTEXT Urtica dioica L. (Urticaceae), stinging nettle, has been employed as a folklore remedy for a wide spectrum of ailments, including urinary disorders, prostatic hyperplasia, and liver diseases. It has been also used traditionally for cancer treatment. OBJECT To evaluate the potential chemopreventive properties of a protein fraction from the aerial part of Urtica dioica (namely UDHL30). MATERIALS AND METHODS UDHL30 has been tested for the antimutagenic activity in bacteria (50-800 μg/plate; Ames test by the preincubation method) and for the cytotoxicity on human hepatoma HepG2 cells (0.06-2 mg/mL; 24 and 48 h incubation). Moreover, the antioxidant activity of UDHL30 (0.1-1200 μg/mL; ABTS and superoxide-radical scavenger assays) was evaluated as potential protective mechanisms. RESULTS UDHL30 was not cytotoxic on HepG2 cells up to 2 mg/mL; conversely, it exhibited a strong antimutagenic activity against the mutagen 2-aminoanthracene (2AA) in all strains tested (maximum inhibition of 56, 78, and 61% in TA98, TA100, and WP2uvrA strains, respectively, at 800 μg/plate). In addition, a remarkable scavenging activity against ABTS radical and superoxide anion (IC50 values of 19.9 ± 1.0 μg/mL and 75.3 ± 0.9 μg/mL, respectively) was produced. DISCUSSION AND CONCLUSIONS UDHL30 possesses antimutagenic and radical scavenging properties. Being 2AA a pro-carcinogenic agent, we hypothesize that the antimutagenicity of UDHL30 can be due to the inhibition of CYP450-isoenzymes, involved in the mutagen bioactivation. The radical scavenger ability could contribute to 2AA-antimutagenicity. These data encourage further studies in order to better define the potential usefulness of UDHL30 in chemoprevention.

Abstract
The antimutagenicity of α-hexylcinnamaldehyde (1), a semisynthetic and more stable derivative of cinnamaldehyde, was evaluated against common environmental pollutants in the bacterial reverse mutation assay. The pre-, co-, and post-treatment protocols were applied to assess the involvement of desmutagenic and/or bioantimutagenic mechanisms. Compound 1 (9-900 μM) produced a strong antimutagenicity (>40% inhibition) in the Salmonella typhimurium TA98 strain against the nitroarenes 2-nitrofluorene and 1-nitropyrene in almost all experimental conditions. A strong inhibition was also reached against the nitroarene 1,8-dinitropyrene and the arylamine 2-aminoanthracene in the cotreatment at the highest concentrations tested. In order to evaluate if an inhibition of bacterial nitroreductase (NR) and O-acetyltransferase (OAT) could be involved in the antimutagenicity of 1 against nitroarenes, the substance was further tested against 1-nitropyrene (activated by both NR and OAT) in TA98NR and TA98 1,8-DNP strains (lacking the NR and OAT enzymes, respectively). Although both desmutagenic and bioantimutagenic mechanisms appear mostly involved in the antimutagenicity of 1, based on data obtained in the TA98NR strain, applying the pretreatment protocol, compound 1 seems to act as an inhibitor of the OAT-mediated mutagen bioactivation. These results provide justification for further studies on 1 as a possible chemopreventive agent.

Abstract
Mutagenicity refers to the induction of permanent changes in the DNA sequence of an organism, which may result in a heritable change in the characteristics of living systems. Antimutagenic agents are able to counteract the effects of mutagens. This group of agents includes both natural and synthetic compounds. Based on their mechanism of action among antimutagens, several classes of compounds may be distinguished. These are compounds with antioxidant activity; compounds that inhibit the activation of mutagens; blocking agents; as well as compounds characterized with several modes of action. It was reported previously that several antitumor compounds act through the antimutagenic mechanism. Hence, searching for antimutagenic compounds represents a rapidly expanding field of cancer research. It may be observed that, in recent years, many publications were focused on the screening of both natural and synthetic compounds for their beneficial muta/antimutagenicity profile. Thus, the present review attempts to give a brief outline on substances presenting antimutagenic potency and their possible mechanism of action. Additionally, in the present paper, a screening strategy for mutagenicity testing was presented and the characteristics of the most widely used antimutagenicity assays were described.

Abstract
Background The increasing consumption of fruits and vegetables has contributed to the improvement of populational health, due in part, to the abundance of antioxidants in these foods. Antioxidants reduce the level of oxidative damage to DNA caused by free radicals and ionizing radiation, including the radioisotope iodine-131 (131I). This isotope is used for the diagnosis and treatment of thyroid injuries, such as hyperthyroidism and cancer. Methods This study aimed to evaluate the radioprotective and cytotoxic activity of acute and subchronic treatments with Barbados Cherry (BC) (Malpighia glabra L.) fruit juice (5 mg), which is rich in potent antioxidants such as vitamin C, phenols, carotenoids, anthocyanins and yellow flavonoids and its activity against the mutagenic activity of the therapeutic dose of 25 μCi of radioiodine for hyperthyroidism. The test system used was the bone marrow cells of Wistar rats (Rattus norvegicus) that were treated in vivo by gavage. Results BC showed radioprotective activity in acute treatments, which is most likely due to the joint action of its antioxidant components. In subchronic treatments, the continuous treatment presented an effective radioprotective activity, which was significantly different from treatment with the radiopharmaceutical only. Treatment with BC prior to (PRE) and simultaneous with (SIM) ionizing radiation decreased the number of induced chromosomal alterations, while post-treatment produced no protective effect. In addition, BC exhibited no cytotoxic activity. Conclusions These data serve as evidence that BC can be used as a preventive health measure to improve public health quality by countering the action of inevitable exposure to mutagens, such as 131I.

Abstract
Natural essential oil constituents play an important role in cancer prevention and treatment. Essential oil constituents from aromatic herbs and dietary plants include monoterpenes, sesquiterpenes, oxygenated monoterpenes, oxygenated sesquiterpenes and phenolics among others. Various mechanisms such antioxidant, antimutagenic and antiproliferative, enhancement of immune function and surveillance, enzyme induction and enhancing detoxification, modulation of multidrug resistance and synergistic mechanism of volatile constituents are responsible for their chemopreventive properties. This review covers the most recent literature to summarize structural categories and molecular anticancer mechanisms of constituents from aromatic herbs and dietary plants.

Abstract
Ample evidence suggests that cancer is triggered by mutagenic damage and diets or supplements capable of reducing such incidences can be related to the prevention of neoplasy development or to an improvement in life quality of patients who undergo chemotherapy. This research aimed to evaluate the antimutagenic and antigenotoxic activity of β-glucan. We set up 8 experimental groups: control (Group 1), cyclophosphamide (Group 2), Groups 3–5 to assess the effect of β-glucan administration, and Groups 6–8 to evaluate the association between cyclophosphamide and β-glucan. The intraperitonial concentrations of β-glucan used were 100, 150 and 200 mg/kg. Micronucleus and comet assays showed that within the first week of treatment β-glucan presented a damage reduction rate between 100–62.04% and 94.34–59.52% for mutagenic and genotoxic damages, respectively. This activity decreased as the treatment was extended. During the sixth week of treatment antimutagenicity rates were reduced to 59.51–39.83% and antigenotoxicity was not effective. This leads to the conclusion that the efficacy of β-glucan in preventing DNA damage is limited when treatment is extended, and that its use as a chemotherapeutic adjuvant need to be better clarified.

Abstract
In this work, the toxicity and genotoxicity of organic solvents (acetone, carbon tetrachloride, dichloromethane, dimethylsulfoxide, ethanol, ether and methanol) were studied using the SOS chromotest. The influence of these solvents on the direct genotoxicity induced by the mutagens mitomycin C (MMC) and 4-nitroquinoline-1-oxide (4-NQO) were also investigated. None of the solvents were genotoxic in Escherichia coli PQ37. However, based on the inhibition of protein synthesis assessed by constitutive alkaline phosphatase activity, some solvents (carbon tetrachloride, dimethylsulfoxide, ethanol and ether) were toxic and incompatible with the SOS chromotest. Solvents that were neither toxic nor genotoxic to E. coli (acetone, dichloromethane and methanol) significantly reduced the genotoxicity of MMC and 4-NQO. When these solvents were used to dissolve vitamin E they increased the antigenotoxic activity of this compound, possibly through additive or synergistic effects. The relevance of these results is discussed in relation to antigenotoxic studies. These data indicate the need for careful selection of an appropriate diluent for the SOS chromotest since some solvents can modulate genotoxicity and antigenotoxicity.

Abstract
β-glucan is an important polysaccharide due to its medicinal properties of stimulating the immune system and preventing chronic diseases such as cancer. The aim of the present study was to determine the anticlastogenic effect of β-glucan in cells exposed to ultraviolet radiation (UV). Chromosome aberration assay was performed in drug-metabolizing cells (HTC) and non drug-metabolizing cells (CHO-K1 and repair-deficient CHO-xrs5), using different treatment protocols. Continuous treatment (UV + β-glucan) was not effective in reducing the DNA damage only in CHO-xrs5 cells. However, the pre-treatment protocol (β-glucan before UV exposition) was effective in reducing DNA damage only in CHO-K1 cells. In post-treatment (β-glucan after UV exposition) did not show significative anticlastogenic effects, although there was a tendency toward prevention. The data suggest that β-glucan has more than one action mechanism, being capable of exerting desmutagenic as well as bio-antimutagenic action. The findings also suggest that the presence of the xenobiotic metabolizing system can reduce the chemopreventive capacity of β-glucan. Therefore, these results indicate that β-glucan from Saccharomyces cerevisiae can be used in the prevention and/or reduction of DNA damage.

Abstract
Several epidemiological and experimental studies has been reported that lutein (LT) presents antioxidant properties. Aim of the present study was to investigate the protective effects of LT against oxidative stress and DNA damage induced by cisplatin (cDDP) in a human derived liver cell line (HepG2). Cell viability and DNA-damage was monitored by MTT and comet assays. Moreover, different biochemical parameters related to redox status (glutathione, cytochrome-c and intracellular ROS) were also evaluated. A clear DNA-damage was seen with cDDP (1.0μM) treatment. In combination with the carotenoid, reduction of DNA damage was observed after pre- and simultaneous treatment of the cells, but not when the carotenoid was added to the cells after the exposure to cDDP. Exposure of the cells to cDDP also caused significant changes of all biochemical parameters and in co-treatment of the cells with LT, the carotenoid reverted these alterations. The results indicate that cDDP induces pronounced oxidative stress in HepG2 cells that is related to DNA damage and that the supplementation with the antioxidant LT may protect these adverse effects caused by the exposure of the cells to platinum compound, which can be a good predict for chemoprevention.

Abstract
An aqueous extract of Kefir, fermented milk originally produced in the Caucasus mountains, suppressed morphological changes of human melanoma HMV-1 and SK-MEL cells and human normal fibroblastTIG-1 cells caused by UVC-irradiation, suggesting that UV damage can be suppressed by the Kefir extract. The addition of the Kefir extract after UVC-irradiation of HVM-1 cells resulted in a remarkable decrease in intracellular reactive oxygen species (ROS) which had been increased by UVC irradiation. The Kefir extract also stimulated unscheduled DNA synthesis and suppressed UVC-induced apoptosis of HMV-1 cells. A colony formation assay revealed that the Kefir extract rescued HMV-1 cells from cell death caused by UVC irradiation. The Kefir extract, as well as methyl methanethiosulfonate which is known to enhance the nucleotide excision repair (NER) activity, exhibited strong thymine dimer repair-enhancing activity. Epigalocatechin exhibited a weak NER activity but vitamins A, C, and E and catechin showed no NER activity. The thymine dimer repair-enhancing factors in the Kefir extract were heat-stable and assumed to be molecules with a molecular weight of less than 5000. The treatment of HMV-1 cells with the Kefir extract during or before UVC- irradiation also prevented the generation of ROS and thymine dimmer, and suppressed the apoptosis of HMV-1 cells, suggesting that application of Kefir can prevent UV damage.

Abstract
The health-promoting potential of 70% ethanolic extracts of 4 rice varieties fermented with Monascus ruber, Phellinus linteus, Cordyceps sinensis and Agaricus blazei was evaluated mainly focusing on their antioxidative and antimutagenic capacities based on the following parameters: phenolic compound and phytic acid content; inhibitory activity on lipid peroxidation; scavenging activity on DPPH radical; suppressing ability on mitomycin C-induced mutagenesis in E. coli cells; and protective effect on 4-nitroquinoline oxide-triggered DNA lesion in V79 hamster cells. The fermented rice extracts were superior in overall health-promoting parameters compared to the source material. The higher antimutagenic activity of the fermented rice extracts might be in part caused by a larger amount of antioxidant constituents such as phenolic compounds or phytic acid. Of the fungal species, Monascus ruber was found to impart a marked increase in both the antioxidative and antimutagenic abilities to the source material. The current study suggests a possibility that such fermented rice may contribute to the prevention of lifestyle-related diseases such as cancer through a daily intake of rice-based diets.

Abstract
The aim of the present study was to assess the genotoxic and antigenotoxic effect of beta-glucan (BG) extracted from barley. The genotoxicity of BG was tested in the single-cell gel electrophoresis assays (SCGE)/HepG2 test system. Moreover, the protective effects of BG against the genotoxicity of B[a]P were studied to delineate its mechanism of antigenotoxicity using four different treatment protocols - pre-treatment, simultaneous simple, simultaneous with pre-incubation, and post-treatment. The results showed that the compound itself was devoid of mutagenic activity at the three lower concentrations studied (1, 5, and 25microg/mL); however, genotoxic and cytotoxic effects were seen at 100 and 200microg/mL, respectively. In combination experiments with B[a]P, pronounced inhibition of DNA migration in the SCGE assay was observed in the two simultaneous treatments, and a smaller reduction was observed in the two other treatments. Thus, the data suggest that BG acts through binding to the genotoxic compound or capturing free radicals produced during its activation. However, the protective effects observed with pre-treatment and post-treatment suggest that the BG may be modulating cell metabolism.

Abstract
Since the middle ages, essential oils have been widely used for bactericidal, virucidal, fungicidal, antiparasitical, insecticidal, medicinal and cosmetic applications, especially nowadays in pharmaceutical, sanitary, cosmetic, agricultural and food industries. Because of the mode of extraction, mostly by distillation from aromatic plants, they contain a variety of volatile molecules such as terpenes and terpenoids, phenol-derived aromatic components and aliphatic components. In vitro physicochemical assays characterise most of them as antioxidants. However, recent work shows that in eukaryotic cells, essential oils can act as prooxidants affecting inner cell membranes and organelles such as mitochondria. Depending on type and concentration, they exhibit cytotoxic effects on living cells but are usually non-genotoxic. In some cases, changes in intracellular redox potential and mitochondrial dysfunction induced by essential oils can be associated with their capacity to exert antigenotoxic effects. These findings suggest that, at least in part, the encountered beneficial effects of essential oils are due to prooxidant effects on the cellular level.

Abstract
In this paper, we reviewed the data on the use of HepG2 cells to detect cytoprotective, antigenotoxic and cogenotoxic agents. Owing to their intact and inducible phase I and phase II enzymes, HepG2 cells are able to activate and detoxify xenobiotics and therefore reflect the metabolism of xenobiotics in the human body better than other metabolically incompetent cells used in conventional in vitro assays. Several dietary and non-dietary agents were found to be protective against different groups of cytotoxic and DNA-damaging xenobiotics in HepG2 cells and the mechanism of protection includes scavenging of electrophiles, reactive oxygen species and peroxides, inhibition of phase I activating enzymes, induction of phase II detoxifying enzymes and interactions with DNA-repair and/or replication processes. Additionally, certain non-mutagenic substances were found to enhance the effect of genotoxic agents in HepG2 cells by increasing the metabolic activation of the latter. In conclusion, HepG2 cells are of great relevance to detect cytotoxic and genotoxic substances and by extension cytoprotective, antigenotoxic and cogenotoxic agents.

Abstract
A systematic structure-activity relationship study of plicatin B (1), an antimutagenic constituent of Psoralea juncea, was undertaken with a view toward elucidating its chemical mode of action and possibly optimizing its antimutagenic activity during the process. Compound 1 and its related analogues were examined for their antimutagenic activity against mutations induced by ethyl methanesulfonate, a direct acting mutagen and alkylating agent, in Salmonella typhimurium strain TA100, utilizing the modified Ames test protocol. The dihydro analogue 3 resulting from saturation of the conjugated alkene double bond of 1 was found to exhibit reduced cytotoxicity and enhanced efficacy relative to the parent compound. This result serves preliminarily to exclude a Michael acceptor role of the alpha,beta-unsaturated carbonyl moiety in connection with its antimutagenic activity.

Abstract
Extracellular interception of mutagens by excreted enzymes or by chemical agents that react with or bind to formed mutagens provides an important means of defense against chemical mutagens/carcinogens. Kada and Shimoi have classified molecules that function in this manner as "desmutagens," and many of them are natural cellular metabolites. Among the specific mechanisms that such agents may employ are: prevention of the activation of "promutagens" to mutagens; stimulation of enzymes (e.g., glutathione-S-transferase) that catalyze the binding/inactivation of damaging electrophiles; direct binding and concomitant inactivation of promutagens or mutagens; interference with uptake of mutagens into cells; etc. De Flora and Ramel have provided an excellent discussion of the mechanisms of these agents and a proposed classification scheme. Drawing on work from our own laboratories and other recent examples in the literature, several examples of mechanistic approaches to these studies using natural plant-derived materials, e.g., humic acid, Glycyrrhiza glabra extract, glutathione, and bioflavonoids, are also described. Antioxidants and agents that conjugate electrophiles will be among the modes of action described for obtaining the goal of intercepting mutagens/carcinogens.

Abstract
Pyridoxal (PL) and pyridoxal 5'-phosphate (PLP) showed a marked bio-antimutagenic effect on UV-induced mutagenesis in E. coli B/r WP2, but not in the DNA excision repair-deficient strain WP2suvrA under the condition where no cellular toxicity was observed. No delay in the first cell division was seen on post-treatment with PL after UV irradiation. PL reduced not only UV- but 4-nitroquinoline-1-oxide-induced mutation, while it was ineffective in N-methyl-N'-nitro-N-nitrosoguanidine- or gamma-ray-treated cells. These results suggest that PL promotes DNA excision repair directly or indirectly and the decrease in the amount of unrepaired DNA damage might cause the reduction of UV-induced mutations in E. coli B/r WP2. In addition to the above observation, PLP reduced the frequency of mitomycin C- (2 mg/kg, i.p.) induced micronuclei in mouse peripheral blood cells. Simultaneous or subsequent oral administration of PLP (25 mg/kg) decreased the frequency of micronucleated peripheral reticulocytes.

Abstract
Sister-chromatid exchanges (SCEs) induced by mitomycin C (MMC), 4-nitroquinoline-1-oxide (4NQO) or UV-light in cultured Chinese hamster ovary cells (CHO K-1 cells) were enhanced by cinoxate (2-ethoxyethyl p-methoxycinnamate) or methyl sinapate (methyl 3,5-dimethoxy 4-hydroxycinnamate). Both substances are cinnamate derivatives and cinoxate is commonly used as a cosmetic UV absorber. Methyl sinapate also increased the frequency of cells with chromosome aberrations in the CHO K-1 cells treated with MMC, 4NQO or UV. These increasing effects of methyl sinapate were critical in the G1 phase of the cell cycle and the decline of the frequencies of UV-induced SCEs and chromosome aberrations during liquid holding was not seen in the presence of methyl sinapate. Both compounds were, however, ineffective in cells treated with X-rays. In cells from a normal human embryo and from a xeroderma pigmentosum (XP) patient, MMC-induced SCEs were also increased by the post-treatment with methyl sinapate. The SCE frequencies in UV-irradiated normal human cells were elevated by methyl sinapate, but no SCE-enhancing effects were observed in UV-irradiated XP cells. Our results suggest that the test substances inhibit DNA excision repair and that the increase in the amount of unrepaired DNA damage might cause the enhancement of induced SCEs and chromosome aberrations.
