Pseudo-symmetric HIV-1proteaseinhibitors containing a novel HMC-hydrazide isostere as the transition-statemimic were designed and synthesized. Most of the synthetic compounds with varied structures at the P and P' sites around this core unit showed potent inhibitory activity against HIV-1protease with nanomolar K(i) values.

A series of HIV protease inhibitor based on the allophenylnorstatine structure with various P-2' moieties were synthesized. Among these analogues, we discovered that a small allyl group would maintain potent enzyme inhibitory activity compared to the o-methylbenzyl moiety in clinical candidate I (KNI-764, also known as JE-2147, AG-1776, or SM-319777). Introduction of all anilinic amino group to 2 (KNI-727) improved water-solubility and anti-HIV-1 activity, X-ray crystallographic analysis of 13k (KNI-1689) with a beta-methallyl group kit P-2' position revealed hydrophobic interactions with Ala28, Ile84, kind Ile50' similar to that of 1. The presence of an additional methyl group on the allyl group in compound 13k significantly increased anti-HIV activity over 1 while providing a rational drug design for structural minimization and improving membrane permeability.
