Abstract

There is currently no specific therapeutics for the HIV-1-related central nervous system (CNS) complications. Here we report that three newly designed CNS-targeting HIV-1 protease inhibitors (PIs), GRL-083-13, GRL-084-13, and GRL-087-13, which contain a P1-3,5- bis -fluorophenyl or P1- para -monofluorophenyl ring, and P2- bis -tetrahydrofuran ( bis -THF) or P2-tetrahydropyrano-tetrahydrofuran ( Tp -THF), with a sulfonamide isostere, are highly active against wild-type HIV-1 strains and primary clinical isolates (50% effective concentration [EC 50 ], 0.0002 to ∼0.003 μM), with minimal cytotoxicity.
