CYP1A1 inhibitor 8a is a potent and selective CYP1A1 inhibitor. It antagonizes B[a]P mediated activation of aromatic hydrocarbon receptor (AhR) in yeast cells, thereby protects human cells from CYP1A1-mediated B[a]P toxicity.
Cytochrome P450 CYP1B1 (190-198) [Homo sapiens] is a peptide from Cytochrome c, which is a small heme protein found loosely associated with the inner membrane of the mitochondrion. Cytochromes c from certain eukaryotes, including plants and fungi but not higher animals, contains methylated lysine residues at specific positions1. Cytochrome c is a required cofactor for Apaf-1 function2.
