Publication Abstract from PubMedLopinavir (LPV) is a second generation HIV-1 protease inhibitor. Drug resistance has rapidly emerged against LPV since its US FDA approval on September 15, 2000. Mutations at residues 32I, L33F, 46I, 47A, I54V, V82A, I84V, and L90M render the protease drug resistant against LPV. We report the crystal structure of a clinical isolate multi-drug resistant (MDR) 769 HIV-1 protease (resistant mutations at residues 10, 36, 46, 54, 62, 63, 71, 82, 84, and 90) complexed with LPV and the in vitro enzymatic IC50 of LPV against MDR 769.
