We report herein the synthesis of novel ring-fused pyrazoloamino pyridine/pyrimidine derivatives as potential FAK inhibitors and the evaluation of pharmaceutical activity against five cancer cell lines (MDA-MB-231, BXPC-3, NCI-H1975, DU145 and 786O). Generally, the majority of compounds displayed strong anti-FAK enzymatic potencies (IC50 < 1 nM) and could effectively inhibit several class of cancer
我们在这里报告了新型的环稠合的吡唑并氨基吡啶/嘧啶衍生物作为潜在的FAK抑制剂的合成以及对五种癌细胞系(MDA-MB-231,BXPC-3,NCI-H1975,DU145和786O)的药物活性的评估。通常,与作为参考的GSK2256098相比,大多数化合物在3μM的浓度范围内均表现出较强的抗FAK酶促作用(IC 50 <1 nM),并能有效抑制几种癌细胞系。其中,由于抗增殖的高敏感性,化合物4o被认为是最有效的。文化方面,4o不仅可以抑制MDA-MB-231细胞中FAK Y397的磷酸化,而且可以剂量依赖的方式触发细胞凋亡。此外,计算对接分析还表明4o和TAE-226显示出与FAK激酶结构域相似的相互作用。
