Design and synthesis of HIV protease inhibitors. Variations of the carboxy terminus of the HIV protease inhibitor L-682,679

J Med Chem. 1991 Sep;34(9):2852-7. doi: 10.1021/jm00113a025.

Abstract

A series of tetrapeptide analogues of 1 (L-682,679), in which the carboxy terminus has been shortened and modified, was prepared and their inhibitory activity measured against the HIV protease in a peptide cleavage assay. Selected examples were tested as inhibitors of virus spread in cell culture. Compound 12 was a 10-fold more potent enzyme inhibitor than 1 in vitro and 30-fold more potent in inhibiting the viral spread in cells.
