New 2-(4-(2-(dimethylamino)ethyl)-4H-1,2,4-triazol-3-yl)pyridine derivatives were synthesized and evaluated for their in vitro cytotoxicity against five cancer cell lines namely MKN-45, H460, HT-29, A549 and U87MG, as well as the normal cell line WI-38. Nearly all the compounds exhibited superior potency to sorafenib with a better selectivity towards the MKN-45, H460 and HT-29 cell lines. In addition
合成了新的2-(4-(2-(二甲基氨基)乙基)-4 H -1,2,4-三唑-3-基)吡啶衍生物并评估了它们对5种癌细胞系MKN-45的体外细胞毒性,H460,HT-29,A549和U87MG,以及正常细胞系WI-38。几乎所有化合物对索拉非尼均表现出优异的效能,并且对MKN-45,H460和HT-29细胞系具有更好的选择性。此外,酶促筛选结果表明,优化后的化合物具有有效的Raf激酶抑制作用以及良好的酶选择性。最有前途的化合物11f具有对IC 50的MKN-45,H460和HT-29细胞高水平的细胞毒性分别对应于索拉非尼针对这些细胞系的IC 50值高51、72和130 nM的值,分别比对应的IC 50值高45.5、30.4和27.8倍。结构-活性关系表明,二甲基氨基乙基对于高活性至关重要。
