  2-[(6-Carboxy-1H-benzoimidazol-2-yl)-difluoro-methyl]-3-methyl-3H-benzoimidazole-5-carboxylic acid tert-butyl ester 在 palladium on activated charcoal 盐酸 、 lithium hydroxide 、 benzotriazol-1-yloxyl-tris-(pyrrolidino)-phosphonium hexafluorophosphate 、 N,N-二异丙基乙胺 、 三氟乙酸 作用下， 以 甲醇 、 N,N-二甲基甲酰胺 为溶剂， 生成 2-{[2-({6-[1-(1-Carboxy-2-phosphono-ethylcarbamoyl)-2-phosphono-ethylcarbamoyl]-1-methyl-1H-benzoimidazol-2-yl}-difluoro-methyl)-3H-benzoimidazole-5-carbonyl]-amino}-3-phosphono-propionic acid

  Highly potent non-peptidic inhibitors of the HCV NS3/NS4A serine protease

  摘要：

  Screening of a diverse set of bisbenzimidazoles for inhibition of the hepatitis C virus (HCV) serine protease NS3/NS4A led to the identification of a potent Zn2+-dependent inhibitor (1). Optimization of this screening hit afforded a 10-fold more potent inhibitor (46) under Zn2+ conditions (K-i = 27 nM). This compound (46) binds also to NS3/NS4A in a Zn2+ independent fashion (K-i = 1 muM). The SAR of this class of compounds under Zn2+ conditions is highly divergent compared to the SAR in the absence of Zn2+, suggesting two distinct binding modes. (C) 2002 Elsevier Science Ltd.
