SYNTHESIS AND ACTIVITY OF HIV PROTEASE INHIBITORS

We report here the synthesis and activity of HIV protease inhibitors. Ln the first stage hydrophobic compounds incorporating a 'carba' bond surrogate or a beta-homologated residue were synthesized. Secondly, we synthesized cyclic compounds in which we incorporated 2-quinoline car boxylic acid in the P3 position and the amino-hydroxyindane moiety in the P'3. The last part of this work was dedicated to a structure/activ ity study of a peptide substrate. These modifications allowed us to wo rk up the synthesis of new pseudopeptide bonds: amino-amide and hydrox y-amide, Compounds with activity in the micromolar range were actually a starting point for the synthesis of new protease inhibitors.
