Clovamide and clovamide-rich extracts of three Trifolium species as antioxidants and moderate antiplatelet agents in vitro
Phytochemistry 2017 Nov;143:54-63.PMID:28777978DOI:10.1016/j.phytochem.2017.07.011.
This in vitro study provides a new insight into the phytochemical, antioxidant, antiplatelet and cytotoxic profiles of commercial trans-Clovamide and clovamide-rich extracts, isolated from aerial parts of three Trifolium species (i.e. T. clypeatum L., T. obscurum Savi and T. squarrosum L.). Under inorganic experimental conditions, the EC50 for the investigated substances varied between 4.87 (clovamide) and 7.91 μg/ml (T. clypeatum) according to the DPPH• assay. The most effective 1 mM ONOO- scavenger was clovamide (IC50 = 19.29 μg/ml), and the weakest was the T. obsucurum extract (IC50 = 41.79 μg/ml). The antioxidant action of the examined substances (1-50 μg/ml) was also evaluated in blood plasma (under 100 μM ONOO--induced oxidative stress) using 3-nitrotyrosine, protein thiol groups, lipid hydroperoxides and thiobarbituric acid-reactive substances as biomarkers. All examined substances were more effective in limiting the oxidative damage to blood plasma components than the nitrative damage. Their anti-nitrative action was statistically significant only at the highest concentration (50 μg/ml). Measurements of platelet adhesion and aggregation found the compounds to have moderate antiplatelet properties of up to 20% inhibition of platelet adhesion at concentrations of 1-5 μg/ml. Additionally, clovamide and Trifolium extracts demonstrated no cytotoxicity towards blood platelets or peripheral blood mononuclear cells.
Antioxidant studies by hydrodynamic voltammetry and DFT, quantitative analyses by HPLC-DAD of clovamide, a natural phenolic compound found in Theobroma Cacao L. beans
Food Chem 2021 Mar 30;341(Pt 2):128260.PMID:33039740DOI:10.1016/j.foodchem.2020.128260.
Clovamide (trans-Clovamide, (2S)-3-(3,4-dihydroxyphenyl)-2-[[(E)-3-(3,4-dihydroxyphenyl)prop-2-enoyl]amino]propanoic acid) is a naturally occurring caffeoyl conjugate and a potent antioxidant found in the phenolic fraction of Theobroma Cacao L. beans. This work quantified clovamide content in single-origin cocoa beans at different production stages (raw, roasted, and winnowed side and end products) by high-performance liquid chromatography with diode array detector (HPLC-DAD). We analyzed the antioxidant activities of clovamide and these extracts by measuring their superoxide radical scavenging capabilities in a Rotating Ring-Disk Electrode (RRDE) electrochemical system against in-situ generated superoxide radical. Our studies concluded a positive correlation between clovamide concentration and the overall antioxidant activities of beans, with the roasting step showing a reduction effect on both. The subsequent refining steps recover the clovamide concentration. Antioxidant studies on clovamide alone by RRDE and density functional theory (DFT) studies led to the conclusion that it is a powerful oxygen radical scavenger, partially contributed by its molecular catechol moieties.
Ethyl acetate extract of Ceiba pentandra (L.) Gaertn. reduces methotrexate-induced renal damage in rats via antioxidant, anti-inflammatory, and antiapoptotic actions
J Tradit Complement Med 2019 Aug 28;10(5):478-486.PMID:32953564DOI:10.1016/j.jtcme.2019.08.006.
Methotrexate (MTX) is a chemotherapeutic agent and an immunosuppressant used to treat cancer and autoimmune diseases. However, its use is limited by its multi-organ toxicity, including nephrotoxicity, which is related to MTX-driven oxidative stress. Silencing oxidative stressors is therefore an important strategy in minimizing MTX adverse effects.Medicinal plants rich in phenolic compounds are probable candidates to overcome these oxidants. Herein, C. pentandra ethyl acetate extract showed powerful in vitro radical-scavenging potential (IC50 = 0.0716) comparable to those of the standard natural (ascorbic acid, IC50 = 0.045) and synthetic (BHA, IC50 = 0.056) antioxidants. The effect of C. pentandra ethyl acetate extract against MTX-induced nephrotoxicity in rats was evaluated by administering the extract (400 mg/kg/day) or the standard antioxidant silymarin (100 mg/kg/day) orally for 5 days before and 5 days after a single MTX injection (20 mg/kg, i.p.).C. pentandra showed slight superiorities over silymarin in restoring the MTX-impaired renal functions, with approximately twofold decreases in overall kidney function tests. C. pentandra also improved renal antioxidant capacity and reduced the MTX-induced oxidative stress. Moreover, C. pentandra inhibited MTX-initiated apoptotic and inflammatory cascades, and attenuated MTX-induced histopathological changes in renal tissue architecture.Phytochemical investigation of the extract led to the purification of the phenolics quercitrin (1), cinchonains 1a (2) and 1b (3), cis-clovamide (4), trans-Clovamide (5), and glochidioboside (6); a structurally similar with many of the reported antioxidant and nephroprotective agents. In conclusion, these data demonstrate that C. pentandra exhibits nephroprotective effect against MTX-induced kidney damage via its antioxidant, antiapoptotic and anti-inflammatory mechanisms.
