Disclosed herein are compounds of the general formula X-A-B-Y wherein X is R1OC(O), R1NHC(O) or R1C(O) wherein R1 is, for example, alkyl, optionally substituted phenyl or optionally substituted benzyl, A is a non-peptide linking unit, e.g. statyl or Phe~[CH2NH]Leu, B is an amino acid residue of glutamic acid or a related derivative thereof, and Y is alkoxy, cycloalkoxy, a substituted alkoxy or a substituted amino group, e.g. cycloalkyl-alkoxy, aralkoxy, alkylamino, (cycloalkyl)alkylamino or aralkylamino. The compounds inhibit the activity of human immunodeficiency virus (HIV) protease and interfere with HIV induced cytopathogenic effects in human cells. These properties render the compounds useful for combating HIV infections. |
