compound 7e also displayed strong activity against AsPC cell line, with an IC50 of 1.66 μM, but show low activity against the normal HPDE6-C7 cells (IC50 > 20 μM), indicating its low cell cytotoxicity. Additionally, flow cytometry analysis showed that after treatment with 7e (8 μM, 72 h), both AsPC and Panc cells growth were almost totally inhibited, with a cell viability rate of 16.8% and 18.1%,
合成了一系列含磷酰胺的二苯基嘧啶类似物(PA-DPPYs)作为有效的粘着斑激酶(FAK)抑制剂。当浓度低于10.69 nM时,PA-DPPY衍生物可以显着抑制FAK的酶活性。其中,化合物7a和7e是两种活性最强的FAK抑制剂,IC 50值分别为4.25 nM和4.65 nM。特别地,化合物7e还显示出对AsPC细胞系的强活性,IC 50为1.66μM,但显示出对正常HPDE6-C7细胞的低活性(IC 50 > 20μM),表明其细胞毒性低。此外,流式细胞仪分析表明7e(8μM,72 h),AsPC和Panc细胞的生长几乎都被抑制,细胞存活率分别为16.8%和18.1%。总体而言,化合物7e可用作治疗胰腺癌的有价值的FAK抑制剂。
