Abstract

A series of nondimethylphenyl-diarylpyrimidines with much lower cytotoxicities than their dimethyl analogues were developed. Compound B13 with a difluorobiphenyl moiety showed the highest Antiviral activity against WT, mutant strains, and RT. The hydrochloride form of B13 exhibited an improved water solubility of 5.6 μg/mL compared with ETR (≪1 μg/mL), better stability in human and rat liver microsomes, and a great oral bioavailability of 44%, making it promising as a drug candidate. In addition, no apparent toxicity was observed in the acute toxicity assay (2 g/kg) and HE staining.
