Enamino-oxindole HIV protease inhibitors

We have designed and synthesized a series of HIV protease inhibitors (PIs) with enamino-oxindole substituents optimized to interact with the S2′ subsite of the HIV protease binding pocket. Several of these inhibitors have sub-nanomolar Ki and antiviral IC50 in the low nM range against WT HIV and against a panel of multi-drug resistant (MDR) strains.
