A series of [1,2,4]triazolo[4,3-a]pyrazine derivatives (4a–4i) were designed, synthesized and evaluated for their c-Met kinase inhibition and antitumor activity against SNU5 gastric cell line in vitro. Among these compounds, 4d was found to show the highest activity against c-Met and high selectivity against the tumor cells which are believed to be dependent on the c-Met oncogene amplification, because
设计,合成和评估了一系列[1,2,4]三唑并[4,3- a ]吡嗪衍生物(4a - 4i)的c-Met激酶抑制作用和对SNU5胃癌细胞系的体外抗肿瘤活性。在这些化合物中,发现4d对c-Met的活性最高,对肿瘤细胞的选择性高,据信这取决于c-Met致癌基因的扩增,因为4d选择性抑制c-Met,而对其他基因无影响59种激酶。对裸鼠人胃(MKN-45)和人非小细胞肺癌(NCI-H1993)肿瘤异种移植的体内功效研究表明4d · CH 3 SO 3H具有比SGX-523更好的抑制活性,呈剂量依赖性。当在小鼠中进行测试时,发现化合物4d · CH 3 SO 3 H具有比JNJ-38877605更高的生物学半衰期和血浆暴露值,并且其长期毒性和急性毒性被认为是可以接受的,所有这表明4d · CH 3 SO 3 H是理想的候选药物。
