A series of potent, selective platelet-derived growth factor receptor-family kinase inhibitors was optimized starting from a globally selective lead molecule 4 through structural modifications aimed at improving the physiochemical and pharmacokinetic properties, as exemplified by 18b. Further clearance reduction via per-methylation of the α-carbons of a solubilizing piperidine nitrogen resulted in advanced leads 22a and 22b. Results from a mouse tumor xenograft, a collagen-induced arthritis model, and a 7 day rat in vivo tolerability study culminated in the selection of compound 22b (AC710) as a preclinical development candidate.
从具有全球选择性的先导分子4开始,通过旨在改善物理化学和药代动力学性质的结构修饰,优化了一系列强效、选择性血小板衍生生长因子受体家族激酶抑制剂,如18b所示。通过对增溶哌啶氮的α-碳进行全甲基化进一步降低清除率,得到了先进的先导化合物22a和22b。小鼠肿瘤异种移植、胶原诱导的关节炎模型和为期7天的大鼠体内耐受性研究的结果最终选定化合物22b(AC710)作为临床前开发候选药物。
