Modification of imidazo[1,2-a]pyridine CDK inhibitors lead to identification of less lipophilic imidazo[1,2-b]pyridazine series of CDK inhibitors. Although several equivalent compounds from these two series have similar structure and show similar CDK activity, the SAR of the two series differs significantly. Protein inhibitor structure determination has confirmed differences in binding mode and given some
咪唑并[1,2-a]吡啶类CDK抑制剂的修饰导致鉴定了亲脂性较低的咪唑并[1,2-b]哒嗪系列CDK抑制剂。尽管这两个系列中的几种等效化合物具有相似的结构并显示出相似的CDK活性,但两个系列的SAR却存在显着差异。蛋白质抑制剂结构的确定已确认结合模式的差异,并对SAR的这些差异有所了解。已经鉴定出有效的和选择性的咪唑并[1,2-b]哒嗪抑制剂的CDK2,在对小鼠口服2mg / kg剂量后,其血浆水平> 1 microM。
