synthesized and evaluated for their c-Met kinase inhibition and cytotoxicity against A549, HT-29, MKN-45 and MDA-MB-231 cancer cell lines in vitro. Several potent compounds were further evaluated against three other cancer cell lines (U87MG, NCI-H460 and SMMC7721). Most of compounds tested exhibited moderate to excellent activity. The studies of SARs identified the most promising compound 28 (c-Met IC50 = 1
合成了一系列新的N 1-(3-氟-4-(6,7-二取代-喹啉-4-基氧基)苯基)-N 4-芳基半碳酰肼衍生物,并评估了它们对c- Met激酶的抑制作用和对A549的细胞毒性,HT-29,MKN-45和MDA-MB-231癌细胞系在体外。进一步针对几种其他癌细胞系(U87MG,NCI-H460和SMMC7721)评估了几种有效的化合物。所测试的大多数化合物均表现出中等至优异的活性。SAR的研究确定了最有前途的化合物28(c -Met IC 50 = 1.4 nM)作为c -Met激酶抑制剂。在这项研究中,有前途的化合物28 鉴定出,与Foretinib相比,对A549,HT-29,U87MG和NCI-H460细胞系分别显示出2.1倍,3.3倍,48.4倍和3.6倍的增长。
