five human cancer cell lines. Preliminary structure–activity relationships of EDOT‐incorporated 2‐propenone derivatives were also established. The EDOT‐appended enones demonstrated significant cytotoxicity against human cancer cell lines. The most active analogue, (E)‐3‐(2,3‐dihydrothieno[3,4‐b][1,4]dioxin‐5‐yl)‐1‐(3,4,5‐trimethoxyphenyl)prop‐2‐en‐1‐one (3 p, GI50=110 nm), severely inhibited the clonogenic
通过缩合反应制备了一系列新的3,4-亚乙基二氧噻吩(EDOT)附加的丙烯酮,并评估了它们对五种人类癌细胞系的体外细胞毒性作用。还建立了EDOT掺入的2-丙烯酮衍生物的初步构效关系。EDOT附加的烯酮对人癌细胞具有明显的细胞毒性。活性最高的类似物(E)-3-(2,3-二氢噻吩并[3,4- b ] [1,4]二恶英-5-基)-1-(3,4,5-三甲氧基苯基)prop-2 ‐en ‐‐‐‐‐‐‐‐‐‐‐‐‐(3 p,GI 50 = 110 n m),严重抑制了癌细胞的克隆潜力,并诱导了G2 / M期的细胞周期停滞,并导致HCT116结肠癌细胞具有> 4 N DNA含量的积累。此外,3 p表现出对人类拓扑异构酶I的酶活性的弱抑制作用。分子对接研究表明,该化合物优先结合至人类检查点2激酶(Chk2)催化域的ATP结合口袋,从而鉴定出新的二芳基2丙烯酮化学型可开发有效的Chk2抑制剂。
