  描述：

  1-benzylpiperidin-4-one pyridin-2-yl hydrazone 在 20 % Pd(OH)2/C 、 甲酸铵 、 N,N-二异丙基乙胺 、 Methanaminium,N-[(dimethylamino)(3H-1,2,3-triazolo[4,5-b]pyridin-3-yloxy)methylene]-N-methyl-, hexafluorophosphate(1-) 作用下， 以 乙醇 、 二氯甲烷 、 N,N-二甲基甲酰胺 为溶剂， 反应 25.0h， 生成 (1R,2R)-N-(1-cyanocyclopropyl)-2-[(1,3,4,5-tetrahydro-1H-pyrido[4,3-b]-7-azaindol-2-yl)carbonyl]cyclohexanecarboxamide

  (1R,2R)-N-(1-Cyanocyclopropyl)-2-(6-methoxy-1,3,4,5-tetrahydropyrido[4,3-b]indole-2-carbonyl)cyclohexanecarboxamide (AZD4996): A Potent and Highly Selective Cathepsin K Inhibitor for the Treatment of Osteoarthritis

  摘要：

  Directed screening of nitrile compounds revealed 3 as a highly potent cathepsin K inhibitor but with cathepsin S activity and very poor stability to microsomes. Synthesis of compounds with reduced molecular complexity, such as 7, revealed key SAR and demonstrated that baseline physical properties and in vitro stability were in fact excellent for this series. The tricycle carboline P3 unit was discovered by hypothesis-based design using existing structural information. Optimization using small substituents, knowledge from matched molecular pairs, and control of lipophilicity yielded compounds very close to the desired profile, of which 34 (AZD4996) was selected on the basis of pharmacokinetic profile.
