ABSTRACT
A series of novel synthetic peptides containing an N-terminal glyoxylyl function (CHOCO-) have been tested as inhibitors of HIV-1 protease. The N-glyoxylyl peptide CHOCO-Pro-Ile-Val-NH2, which fulfills the specificity requirements of the MA/CA protease cleavage site together with the criteria of transition state analogue of the catalyzed reaction, was found to be a moderate competitive inhibitor although favorable interactions were visualized between its hydrated form and the catalytic aspartates using molecular modeling. Increasing the length of the peptide sequence led to compounds acting only as substrates.
