The effect of anthocyans on the expression of selected phase II xenobiotic-metabolizing enzymes in primary cultures of human hepatocytes.

Anthocyans are biologically active constituents of various berry fruits and they are also contained in nutritional supplements derived from extracts or dry matter from berry fruits. In this study we evaluated the effects of anthocyans on the expression of selected drug-metabolizing phase II genes in primary cultures of human hepatocytes by qRT-PCR. Most of the tested anthocyanidins (6) and anthocyanins (21) did not induce the expression of mRNA of UGT1A/2B members in human hepatocytes.

Differential effects of omeprazole and lansoprazole enantiomers on aryl hydrocarbon receptor in human hepatocytes and cell lines.

Proton pump inhibitors omeprazole and lansoprazole contain chiral sulfur atom and they are administered as a racemate, i.e. equimolar mixture of S- and R-enantiomers.

Effects of anthocyanidins and anthocyanins on the expression and catalytic activities of CYP2A6, CYP2B6, CYP2C9, and CYP3A4 in primary human hepatocytes and human liver microsomes.

Anthocyanidins and anthocyanins are pharmacologically active constituents of various berry fruits, such as blueberry and cranberry. These compounds are also contained in massively used nutritional supplements based on extracts or dry matter from berry fruits. The current study evaluated the effects of anthocyanidins and anthocyanins on the expression and catalytic activity of major drug-metabolizing enzymes CYP2C9, CYP2A6, CYP2B6, and CYP3A4 in primary cultures of human hepatocytes and human liver microsomes.
