Abstract: SB203386 is a potent inhibitor of HIV-1
protease (Ki = 18 nM) but shows decreased inhibition of the HIV-1
protease (
Val32Ile,
Ile47Val,
Val82Ile) triple mutant (Ki = 112 nM) and SIV
protease (Ki = 960 nM).
Abstract: To gain greater understanding of the structural basis of human immunodeficiency virus (HIV)
protease ligand specificity, we have crystallized and determined the structures of the HIV-1
protease (
Val32Ile,
Ile47Val,
Val82Ile) triple mutant and simian immunodeficiency virus (SIV)
protease in complex with SB203386, a tripeptide analogue inhibitor containing a
