Four series of N-methylpicolinamide moiety and thienopyrimidine moiety bearing pyridazinone were designed and synthesized and evaluated for the IC50 values against three cancer cell lines (A549, HepG2 and MCF-7) and some selected compounds were further evaluated for the activity against c-Met, Flt-3, VEGFR-2, c-Kit and EGFR kinases. Three compounds (35, 39 and 43) showed more active than positive control
设计并合成了带有哒嗪酮的四个系列的N-甲基吡啶甲基酰胺部分和噻吩并嘧啶部分,并评估了其对三种癌细胞系(A549,HepG2和MCF-7)的IC 50值,并进一步评估了一些所选化合物对c-的活性Met,Flt-3,VEGFR-2,c-Kit和EGFR激酶。三种化合物(35,39和43)比阳性对照Foretinib表现出更多的活性对A549,HepG2和MCF-7细胞系。最有前途的化合物43表现出对A549,HepG2和MCF-7的优异活性,其IC 50为500.58±0.15 µM,0.47±0.06 µM和0.74±0.12 µM的活性分别比福瑞替尼高3.73–5.39倍。基于酶的实验表明,有43种酶选择性抑制c-Met,IC 50值为16 nM,与Foretinib(14 nM)具有相同的活性,并且比化合物5(90 nM)更好。此外,还进行了AO和Annexin V / PI染色和对接研究。
