identification of the most promising compound 1D-2 which exhibited significant inhibitory effect on both enzymatic (IC50=1.45nM) and cellular (IC50=24.7nM in H1993 cell line) assays, as well as exquisite selectivity and satisfactory metabolic stability in human and rat liver microsomes.
异常的c-Met激活与多种肿瘤致癌过程和耐药性有关。本研究设计并合成了一系列咪唑并[4,5-b]吡嗪衍生物,并对其体外抑菌活性进行了评价。系统地研究了结构活性关系(SAR),并进行了对接分析以阐明结合模式,从而鉴定出最有前途的化合物1D-2,该化合物对酶促(IC50 = 1.45nM)和细胞( H1993细胞系中的IC50 = 24.7nM,以及在人和大鼠肝微粒体中的精湛选择性和令人满意的代谢稳定性。
