  Small-Sized Human Immunodeficiency Virus Type-1 Protease Inhibitors Containing Allophenylnorstatine to Explore the S₂′ Pocket

  摘要：

  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.
