<p>Disclosed herein are compounds of the general formula X-A-B-C'-D-Y wherein X is a terminal group, for example, alkanoyl or phenylalkanoyl radicals, A is an amino acid residue having a lower alkyl or lower cycloalkyl side chain, e.g. Ala or val, B is a non-peptide linking unit, e.g. statyl or Phe psi [CH2NH]Leu, C' is an amino acid residue of alpha -amino- beta -cycloalkylpropionic acid, glutamic acid or alpha -aminoadipic acid, or a related derivative thereof, D is an amino-acid residue, for example, Phe or Val, and Y is hydroxy, alkoxy, amino, alkylamino or dialkylamino. 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 used for combating HIV infections.</p> |
