Potent HIV Protease Inhibitors: The Development of Tetrahydrofuranylglycines as Novel P2 Ligands and Pyrazine Amides as P3-Ligands

A series of protease inhibitors bearing constrained unnaturel amino acids at the P2-position and novel heterocycles at the P3-position of compound 1 (Ro 31-8959) were synthesized, and their in vitro enzyme inhibitory and antiviral activities were evaluated.Replacement of P2-asparagine of compound 1 with (2S,3’R)-tetrahydrofuranylglycine resulted in improvement in enzyme inhibitory as well as antiviral potencies (compound 23).Interestingly, incorporation of (2S,3’S)-tetrahydrofuranylglycine at the P2-position proved to be less effective.The resulting compound 2 4 was 100-fold less potent than the 2S,3R-isomer (compound 23).This stereochemical preference indicated a hydrogen-bonding interaction between the tetrahydrofuranyl oxygen and the residues of the S2-region of the enzyme active site.Furthermore, replacement of P3-quinolinoyl ligand of 1 with various novel heterocycles resulted in potent inhibitors of HIV proteases.Of particular interest, compound 2 with (2S,3’R)-tetrahydrofuranylglycine at P2 and pyrazine derivative at P3 is one of the most potent inhibitors of HIV-1 (IC50 value 0.07 nM) and HIV-2 (IC50 value 0.18 nM) proteases.Another important result in this series is the identification of compound 27 in which the P2-P3- amide carbonyl has been removed.The resulting compound 27 has exhibited improvement in antiviral potency while retaining the enzyme inhibitory potency similar to compound 1.
