discovery and characterization of 7k (BMS-582949), a highly selective p38α MAP kinase inhibitor that is currently in phase II clinical trials for the treatment of rheumatoid arthritis, is described. A key to the discovery was the rational substitution of N-cyclopropyl for N-methoxy in 1a, a previously reported clinical candidate p38α inhibitor. Unlike alkyl and other cycloalkyls, the sp2 character of
描述了7k(BMS-582949)的发现和表征,这是一种高度选择性的p38αMAP激酶抑制剂,目前正处于治疗类风湿关节炎的II期临床试验中。该发现的关键是在1a中用N-环丙基合理取代N-甲氧基,这是先前报道的临床候选p38α抑制剂。与烷基和其他环烷基不同,环丙基的sp 2特性可赋予直接取代的酰胺NH改善的氢键特性。抑制剂7k的活性略低于1a在p38α酶促分析中显示出良好的药代动力学特性,因此在急性小鼠炎症模型和假建立的大鼠AA模型中更有效。通过X射线晶体学分析证实了7k与p38α的结合模式。
