In this study, we designed and synthesized a number of novel pyrido[3,4-d]pyrimidine-thiazolidine-1,2,4-oxadiazole derivatives and investigated them in vitro for their inhibitory action toward epidermal growth factor receptor (EGFR) kinases and antiproliferative activity against two different cell lines, MCF-7 and A-549. When compared to the lead chemicals, 5-fluorouracil and erlotinib, some of the compounds demonstrated acceptable activity. Among them, the most promising compounds 4d and 4e displayed potent anticancer activity against both MCF-7 and A-549 cell lines (IC50 values remaining: 1.97 ± 0.28 μM to 8.14 ± 0.52 μM, respectively); the comparative IC50 values for 5-fluorouracil and erlotinib in these cell lines were 5.56 ± 0.34 μM, 12.66 ± 0.76 μM, and 3.64 ± 0.49 μM, 9.54 ± 0.75 μM, respectively; as well as excellent kinase inhibitory activities (EGFR: IC50 = 0.34 ± 0.07 μM and 0.42 ± 0.06 μM) were more effective than the conventional drug Erlotinib (IC50 = 0.42 ± 0.02 μM).

新型吡啶并[3,4-d]嘧啶-噻唑烷-1,2,4-恶二唑的合成作为有效的EGFR靶向抗癌药物



在本研究中,我们设计并合成了许多新型吡啶并[3,4- d ]嘧啶-噻唑烷-1,2,4-恶二唑衍生物,并在体外研究了它们对表皮生长因子受体(EGFR)激酶的抑制作用以及针对两种不同细胞系 MCF-7 和 A-549 的抗增殖活性。与主要化学品 5-氟尿嘧啶和厄洛替尼相比,一些化合物表现出可接受的活性。其中,最有前途的化合物4d4e对MCF-7和A-549细胞系均表现出有效的抗癌活性(剩余IC 50值分别为:1.97±0.28μM至8.14±0.52μM); 5-氟尿嘧啶和厄洛替尼在这些细胞系中的比较 IC 50值分别为 5.56 ± 0.34 μM、12.66 ± 0.76 μM 和 3.64 ± 0.49 μM、9.54 ± 0.75 μM;以及优异的激酶抑制活性(EGFR:IC 50 = 0.34 ± 0.07 μM 和 0.42 ± 0.06 μM),比传统药物厄洛替尼(IC 50 = 0.42 ± 0.02 μM)更有效。
