The syntheses, in vitro characterizations, and rat and monkey in vivo pharmacokinetic profiles of a series of 5-, 6-, and 7-methyl-substituted azepanone-based cathepsin K inhibitors are described. Depending on the particular regiochemical substitution and stereochemical configuration, methyl-substituted azepanones were identified that had widely varied cathepsin K inhibitory potency as well as pharmacokinetic
描述了一系列5-,6-和7-甲基取代的氮杂环庚烷基组织蛋白酶K抑制剂的合成,体外表征以及大鼠和猴的体内药代动力学。根据特定的区域化学取代和立体化学构型,鉴定出与4S亲本氮杂环庚烷类似物1(人组织蛋白酶K,K(i,app) = 0.16 nM,大鼠口服生物利用度= 42%,大鼠体内清除率= 49.2 mL / min / kg。特别值得注意的是,4S-7-顺式甲基氮杂S酮类似物10与人组织蛋白酶K的K(i,app)= 0.041 nM,口服生物利用度为89%,在体内的体内清除率为19.5 mL / min / kg。那只老鼠。使用X射线晶体学和构象分析方法可以得出使这些密切相关的类似物的某些观察到的特征合理化的假设。这些实施例证明了通过替代氮杂庚酮核心来调节组织蛋白酶抑制剂的药理性质的潜力。抑制组织蛋白酶K的高效力以及化合物10(也称为SB-462795或relacatib)的良好的大鼠和猴
