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.
