M. Vaillancourt et al., DIFUNCTIONAL ENOLS OF N-PROTECTED AMINO-ACIDS AS LOW-MOLECULAR-WEIGHTAND NOVEL INHIBITORS OF HIV-1 PROTEASE, Bioorganic & medicinal chemistry letters, 3(6), 1993, pp. 1169-1174
The synthesis of difunctional enols of simple amino acids and their no
vel inhibitory activity against human immunodeficiency virus type 1 pr
otease (HIV-PR) are described. By modifying the substituents on these
enols, we were able to achieve mid-nanomolar range in activity against
HIV-1 protease which is, to our knowledge, the best reported activity
for molecules that do not contain at least one peptide linkage.
