7-Ethoxy-4-trifluoromethylcoumarin (7-EFC) was examined as a substrate for cytochrome P450 (P450) in microsomes from human livers and expressed in B-lymphoblastoid cells. The O-deethylation of 7-EFC to 7-hydroxy-4-trifluoromethylcoumarin (7-HFC) varied over a liver bank (n = 19) by a factor of

Two UDP-glucuronosyltransferases (UGT2B9(*)2 and UGT2B33) have been isolated from female rhesus monkey liver. Microsomal preparations of the cell lines expressing the UGTs catalyzed the glucuronidation of the general substrate 7-hydroxy-4-(trifluoromethyl)coumarin in addition to selected estrogens (beta-estradiol and estriol) and opioids

The O-deethylation of 7-ethoxy-4-trifluoromethylcoumarin (EFC) by liver microsomes has been assessed as a method for monitoring the activity of cytochrome P450. The principle advantage of this substrate is the formation of a fluorescent product 7-hydroxy-4-trifluoromethylcoumarin (HFC) which can be assayed
