7ETMC		Alkynes
7ETMC is a cytochrome P450 inhibitor with selective inhibition of human cytochrome P450s 1A1 and 1A2. 7ETMC has inhibitory effects on P450s 1A1 and 1A2 with IC?? values of 0.46μM and 0.50μM, respectively, within the first six minutes, and has no inhibitory activity against P450s 2A6 and 2B1. Except for 7-ethynyl-3-methyl-4-phenylcoumarin, the remaining inhibitors show mechanism-based inhibition of P450s 1A1 and 1A2.
