摘要:
5,6-Dihydro-1H-pyridin-2-one analogs were discovered as a novel class of inhibitors of genotype 1 HCV NS5B polymerase. Among these, compound 4ad displayed potent inhibitory activities in biochemical and replicon assays (IC(50) (1b) < 10 nM; IC(50) (1a) < 25 nM, EC(50) (1b) = 16 nM), good in vitro DMPK properties, as well as moderate oral bioavailability in monkeys (F = 24%).
