Synthesis and biological evaluation of novel small non-peptidic HIV-1 PIs: The benzothiophene ring as an effective moiety

Abstract

Synthesis and biological evaluation of a new series of potential HIV-1 protease inhibitors incorporating different heterocycles are described. The variation of heteroatom in such molecules has displayed totally different biological activities and a benzothiophene containing inhibitor has shown high potency against wild type HIV-1 protease with IC50 = 60 nM, thanks to the lower desolvation penalty to be payed by such hydrophobic moiety
