A series of novel thieno[3,2-d]pyrimidine derivatives possessing diaryl semicarbazone scaffolds were designed, synthesized and evaluated for their anticancer activity. Most compounds displayed good to excellent potency against four tested cancer cell lines as compared with GDC-0941 and sorafenib. In this study, a promising compound 36 (PI3Kα IC50 = 0.027 μM) was identified, which showed the most potent
设计,合成并评价了一系列具有二芳基半脲酮骨架的新型噻吩并[3,2- d ]嘧啶衍生物。与GDC-0941和索拉非尼相比,大多数化合物对四种测试的癌细胞系表现出良好至极佳的效能。在这项研究中, 鉴定出了有前途的化合物36(PI3KαIC 50 = 0.027μM ),显示出最有效的抗肿瘤活性,针对H460,HT-29,IC 50值分别为0.057μM,0.039μM,0.25μM和0.23μM 。分别是MKN-45和MDA-MB-231细胞系。此外,SAR分析表明,噻吩并[3,2- d]嘧啶部分显示出比带有链氨基的化合物优越的活性。另外,在末端苯环的3-位具有单甲氧基或在3,5-位具有二甲基的化合物更具活性。SAR分析将指导我们进一步完善噻吩并[3,2- d ]嘧啶衍生物的结构,以实现最佳的抗癌活性。
