Bioconversion of (-)-epicatechin, (+)-epicatechin, (-)-catechin, and (+)-catechin by (-)-epigallocatechin-metabolizing bacteria.
Bioconversion of (-)-epicatechin (-EC), (+)-epicatechin (+EC), (-)-catechin (-C), and (+)-catechin (+C) by (-)-epigallocatechin (-EGC)-metabolizing bacteria, Adlercreutzia equolifaciens MT4s-5, Eggerthella lenta JCM 9979, and Flavonifractor plautii MT42, was investigated. A. equolifaciens MT4s-5 could catalyze C ring cleavage to form (2S)-1-(3,4-dihydroxyphenyl)-3-(2,4,6-trihydroxyphenyl)propan...
متن کاملProcyanidin dimer B2 [epicatechin-(4 -8)-epicatechin] in human plasma after the consumption of a flavanol-rich cocoa1–3
Background: Epidemiologic studies have linked flavonoid-rich foods with a reduced risk of cardiovascular mortality. Some cocoas are flavonoid-rich and contain the monomeric flavanols ( )-epicatechin and (+)-catechin and oligomeric procyanidins formed from these monomeric units. Both the monomers and the oligomers have shown potential in favorably influencing cardiovascular health in in vitro an...
متن کاملEpicatechin: endothelial function and blood pressure.
Epidemiological studies indicate an inverse relationship between flavanol intake and the risk of cardiovascular disease. Potential mechanisms include their effects on endothelial function and hypertension. A number of studies have shown that flavanol-rich cocoa reduces blood pressure and endothelial dysfunction, whereas black tea may have opposite effects. These results highlight the importance...
متن کاملAntifungal synergy of theaflavin and epicatechin combinations against Candida albicans.
New antifungal agents are required to compensate for the increase in resistance to standard antifungal agents of Candida albicans, which is an important opportunistic fungal pathogen that causes minor infections in many individuals but very serious infections in those who are immune-compromised. In this study, combinations of theaflavin and epicatechin are investigated as potential antifungal a...
متن کاملAbsorption and metabolization of cytoprotective epicatechin thio conjugates in rats.
The epicatechin (EC) thio derivatives 4β-(S-cysteinyl)-epicatechin (Cys-EC) and 4β-(S-cysteaminyl)-epicatechin (Cya-EC) are compounds that may provide protection from oxidation via mechanisms involving either the flavonoid moiety or the nonphenolic cysteine or cysteamine part of the molecule. Because the metabolically modified molecules may be the actual active species, we estimated the absorpt...
