Cytochrome substrates
WebFor most substrates, multiple cDNA-expressed cytochrome P450 isoforms were found to catalyze the formation of the fluorescent product. However, among the combinations tested, rat CYP2D2 displayed high selectivity for AMMC demethylation (a substrate selective for CYP2D6 in human liver microsomes). WebAn in silico model for predicting human cytochrome P450 2B6-substrate interactions was generated based on a novel scheme, which was initially devised to predict the hERG liability (reported in Leong, M. K., Chem. Res. Toxicol., 2007, 20, 217.) using pharmacophore ensemble/support vector machine to take into account the protein conformational …
