A series of novel 5-methylpyrazolo[1,5-a]pyrimidine derivatives (10a–10x) were designed, synthesized, and evaluated for their in vitro inhibitory activities against c-Met kinase and antiproliferative activities against the SH-SY5Y, MDA-MB-231, A549, and HepG2 cell lines. Most of the compounds remarkably inhibited c-Met kinase and showed moderate to good cytotoxicity and selectivity toward the four
设计,合成了一系列新颖的5-甲基吡唑并[1,5-a]嘧啶衍生物(10a-10x),并评估了其对c-Met激酶的体外抑制活性以及对SH-SY5Y,MDA-的抗增殖活性。 MB-231,A549和HepG2细胞系。大多数化合物显着抑制c-Met激酶,并显示出对四种癌细胞的中等至良好的细胞毒性和选择性。其中,化合物10b和10f是两种最有效的选择性c-Met抑制剂,抑制浓度最高一半(IC 50)值分别为5.17±0.48 nM和5.62±0.78 nM,其抑制能力与阳性对照卡博替尼相当。细胞增殖试验进一步证明,两种最有希望的化合物10a和10b对MDA-MB-231细胞也显示出良好的细胞毒性和选择性,IC 50值分别为26.67±2.56μM和26.83±2.41μM。化合物10f和10g对A549细胞具有细胞毒性和选择性,IC 50分别为20.20±2.04μM和21.65±1.58μM。所有
