Herein, we designed and synthesized of a novel series of 7,8-dihydro-5H-thiopyrano[4,3-d]pyrimidine derivatives bearing chromone moiety (10a–j, 13a–j). All the compounds were evaluated for the IC50 values against five cancer cell lines (A549, PC-3, MCF-7, Hela and HepG2). Seven of the target compounds exhibited moderate to excellent cytotoxicity. For these compounds, we tested their inhibitory activities
在这里,我们设计并合成了一系列带有色酮部分(10a – j,13a – j)的7,8-二氢-5 H-硫代吡喃并[4,3- d ]嘧啶衍生物。对所有化合物针对五种癌细胞系(A549,PC-3,MCF-7,Hela和HepG2)的IC 50值进行了评估。七种目标化合物表现出中度至优异的细胞毒性。对于这些化合物,我们测试了它们对mTOR激酶的抑制活性,其中四个进一步测试了对PI3Kα激酶的抑制活性。结果表明,优化后的化合物10j对mTOR激酶,PI3Kα激酶和5种癌细胞系表现出优异的抑制活性和细胞毒性,IC 50值分别为1.1μM,0.92μM和8.77–14.3μM。结构-活性关系(SARs)和对接研究表明,硫代吡喃并[4,3- d ]嘧啶骨架对目标化合物的抗肿瘤活性影响很小。C-6位的色酮部分被羧基取代有利于其抗肿瘤活性。
