                                摘要:
                                A series of benzofused heterocycles was examined to replace the metabolically unstable benzyl alcohol P2/P2' groups of DMP 323 (1). Extremely potent inhibitors of HIV protease (Ki < 0.01 nM) and excellent antiviral activity (IC90 = 8 nM) were found. An X-ray crystal structure of benzimidazolone 5a bound to HIV protease showed H-bonds to Asp30 and a bridging water molecule to Gly48. Copyright (C) 1996 The DuPont Merck Pharmaceutical Company.
