An Integrated Approach to the Anti-Inflammatory, Antioxidant, and Genotoxic Potential of Portuguese Traditional Preparations from the Bark of Anacardium occidentale L. PLANTS (BASEL, SWITZERLAND) 2024; 13:420. [PMID: 38337956 PMCID: PMC10857173 DOI: 10.3390/plants13030420] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/22/2023] [Revised: 01/21/2024] [Accepted: 01/29/2024] [Indexed: 02/12/2024]
Abstract
Anacardium occidentale L. stem bark Traditional Herbal Preparations (AoBTHPs) are widely used in traditional medicine to treat inflammatory conditions, such as diabetes. The present study aims to evaluate the anti-inflammatory, antioxidant, and genotoxic potential of red and white Portuguese AoBTHPs. Using a carrageenan-induced rat paw edema model, a significant anti-edema effect was observed for all tested doses of white AoBTHP (40.2, 71.5, and 127.0 mg/kg) and the two highest doses of red AoB THP (71.5 and 127.0 mg/kg). The anti-edema effect of red AoBTHP's highest dose was much more effective than indomethacin 10 mg/kg, Trolox 30 mg/kg, and Tempol 30 mg/kg. In DPPH, FRAP, and TAC using the phosphomolybdenum method, both types of AoBTHPs showed similar antioxidant activity and no genotoxicity up to 5000 µg/plate in the Ames test. The LC-UV/DAD-ESI/MS fingerprint allowed the identification of gallic and protocatechuic acids as the two main marker compounds and the presence of catechin, epicatechin, epigallocatechin gallate, and ellagic acid in both AoBTHPs. The obtained results support the validation of red and white AoB and their THPs as anti-inflammatory agents and contribute to the possible development of promising new therapeutic options to treat inflammatory conditions.

Abstract
Black Mulberry (Morus nigra L.) belongs to Moraceae family. The present study evaluated the possible genotoxic and/or protective activities of black mulberry fruit juice (BMFJ), in vitro, using mitomycin C (MMC) as a positive control, by chromosomal aberrations and micronucleus assays. Human lymphocytes were treated with BMFJ concentrations alone (1/1, 1/2, 1/4, 1/8 dilutions), pretreatment (49h) (0.20 μg/ml MMC+ 1/1 BMFJ, 0.20 μg/ml MMC+1/2 diluted BMFJ, 0.20 μg/ml MMC+1/4 diluted BMFJ, 0.20 μg/ml MMC+1/8 diluted BMFJ) and simultaneous-treatment (48h) (0.20 μg/ml MMC+ 1/1 BMFJ, 0.20 μg/ml MMC+1/2 diluted BMFJ, 0.20 μg/ml MMC+1/4 diluted BMFJ, 0.20 μg/ml MMC+1/8 diluted BMFJ). The in vitro results demonstrated that BMFJ showed no genotoxicity, but it significantly decreased chromosomal aberration and micronucleus frequency induced by MMC. Our results showed that all concentrations of BMFJ revealed no genotoxicity but protective activity against genomic changes induced by anti-tumor agent MMC in human lymphocytes. Protective effects of BMFJ on MMC induced chromosomal damages most probably due to its free radical scavenging activity.

Abstract
A new steroidal ester bearing n-nonadecanoyl moiety (1) and a mixture of isomeric cerebrosides (2) along with two known compounds were isolated from the methanol extract of the stem-bark of Anacardium occidentale. The structure of the new steroidal ester was determined as 3-n-nonadecanoyl-β-sitosterol on the basis of modern spectroscopic techniques (IR, ESI-MS, HR-ESIMS, 1D and 2D NMR) and chemical degradation studies. The structures of the known compounds were identified as gallic acid and tanacetene by comparison of the spectroscopic data with those of reported data. The mixture of cerebrosides was confirmed based on the analysis of 1D and 2D NMR. These compounds were evaluated for cytotoxicity against human cancer cell lines A549, SCOV3 and rat normal cell line NRK49f.

Abstract
AIM OF THE STUDY Anacardium occidentale Linn. (cashew) is a Brazilian plant that is usually consumed in natura and is used in folk medicine. Anacardic acids (AAs) in the cashew nut shell liquid are biologically active as gastroprotectors, inhibitors of the activity of various deleterious enzymes, antitumor agents and antioxidants. Yet, there are no reports of toxicity testing to guarantee their use in vivo models. MATERIALS AND METHODS We evaluated AAs biosafety by measuring the acute, subacute and mutagenic effects of AAs administration in BALB/c mice. In acute tests, BALB/c mice received a single oral dose of 2000 mg/kg, whereas animals in subacute tests received 300, 600 and 1000 mg/kg for 30 days. Hematological, biochemical and histological analyses were performed in all animals. Mutagenicity was measured with the acute micronucleus test 24h after oral administration of 250 mg/kg AAs. RESULTS Our results showed that the AAs acute minimum lethal dose in BALB/c mice is higher than 2000 mg/kg since this concentration did not produce any symptoms. In subacute tests, females which received the highest doses (600 or 1000 mg/kg) were more susceptible, which was seen by slightly decreased hematocrit and hemoglobin levels coupled with a moderate increase in urea. Anacardic acids did not produce any mutagenic effects. CONCLUSIONS The data indicate that doses less than 300 mg/kg did not produce biochemical and hematological alterations in BALB/c mice. Additional studies must be conducted to investigate the pharmacological potential of this natural substance in order to ensure their safe use in vivo.

Abstract
Anacardium occidentale Linn. (Anacardiaceae) is a plant largely used in Africa for the treatment of different diseases. In Côte d'Ivoire it's commonly used for the treatment of hypertension. The present study was carried out in order to assess the effects of Anacardium occidentale extract (ANOE) on cardiovascular parameters in animal models. A mercury manometer kymograph of Ludwig was used to measure the blood pressure of normotensive rabbits in control conditions (normal physiological solution) and under the influence of ANOE. The contractile activity of an isolated rat heart was also measured in control conditions and under the influence of ANOE in different physiological media using a modified Langendhorff (1895) apparatus. The aqueous Anacardium occidentale (ANOE) bark extract applied intravenously in different doses (12, 40, 90, and 167 mg/kg b.w.), produced a significant dose-dependent decrease in blood pressure of previously normotensive rabbits (up to 89% vs control). Atropine (1 mg/ml) pre-treatment failed to reverse the hypotensive effects elicited by the extract. ANOE applied to isolated rat heart preparations in different concentrations (0.01, 0.1, 1.0, and 10 µg/ml) induced negative inotropic and chronotropic effects. Atropine pre-treatment of heart preparations (0.1 µg/ml) failed to reverse the negative effects induced by ANOE. The extract's action on heart contractile activity studied in modified culture media further confirmed its cardio-inhibitory effects. ANOE induced strong hypotensive and cardio-inhibitory effects in animal models.

Abstract
Annatto (AN), a natural food colorant rich in carotenoids, has been reported as being an effective antioxidant, but little is known about its potential chemopreventive properties. In this study, we evaluated the ability of AN to protect human hepatoma cells (HepG2) from micronucleus (MN) induction against three different mutagens: benzo(a)pyrene (B(a)P), doxorubicin (DXR), and methyl methanesulfonate (MMS). In an attempt to clarify the possible mechanism of antimutagenicity of AN, three protocols of treatment were applied (pretreatment; simultaneous treatment, and post-treatment with AN following treatment with the mutagens). Also, cells exposed only to AN were assayed for cytotoxicity and mutagenicity. A dosage up to 10 microg/ml of AN was devoid of mutagenic activity. Protective effects were seen on micronuclei induced by B(a)P and DXR using pre and simultaneous treatment, but AN had no significant effect on MN induction by MMS in any of the protocols. Our results also show that exposure of cells to concentrations of AN higher than 10 microg/ml decreased cell viability. Taken together, our findings indicate that AN presents antimutagenic activity in vitro, but its protective effect is dependent on the mutagen and on type of treatment suggesting its potential use as a chemopreventive agent.

Abstract
Evaluation of the reliability of toxicological data is of key importance for regulatory decision-making. In particular, the new EU Regulations concerning the registration, evaluation, authorisation and restriction of chemicals (REACH) and classification, labelling and packaging (CLP) according to the new globally harmonised system (GHS) rely on the integration of all available toxicological information. The so-called Klimisch categories, although well established and widely used, lack detailed criteria for assigning data quality to categories. A software-based tool (ToxRTool) was developed within the context of a project funded by the European Commission to provide comprehensive criteria and guidance for reliability evaluations of toxicological data. It is applicable to various types of experimental data, endpoints and studies (study reports, peer-reviewed publications) and leads to the assignment to Klimisch categories 1, 2 or 3. The tool aims to increase transparency and to harmonise approaches of reliability assessment. The tool consists of two parts, one to evaluate in vivo and one to evaluate in vitro data. The prototypes of the tool were tested in two independent inter-rater experiments. This approach allowed the analysis of the performance of the tool in practice and the identification and minimisation of sources of heterogeneity in evaluation results. The final version, ToxRTool, is publicly available for testing and use.

Abstract
Plants remain to be a great source of medicines for humanity. Among them is the Anacardium occidentale L. species, popularly known as the cashew, which has several therapeutic indications, such as cicatrizing, antihypertensive, hypoglycemic and antitumoral properties. The objective of the present work was to assess the mutagenicity and antimutagenicity of cashew stem bark methanolic extract (CSBME) on cell cultures of Chinese hamster lung fibroblasts (V79). The cultures were treated with different concentrations of the CSBME (500, 1000 and 2000 microg/mL) or with the extract associated with doxorubicin (DXR, 0.75 microg/mL) during the cell cycle phases G1, S, and G2 and throughout continuous treatment. Apart from these treatments, the cell cultures were also treated with PBS (negative-control) and DXR (positive-control). The data obtained in the chromosome aberrations (CA) test showed a significant reduction in CA frequency in the cultures treated with DXR and extract in comparison with those that received only DXR during the cell cycle phases G1 and S and throughout the entire cycle, as well as the absence of mutagenicity in all the treatments realized. The antimutagenic effect observed in this work reinforces the presence of the previously described therapeutic properties of cashew and indicates the safe use of this extract.
