new antimitotic agents based on the recently reported pyrimido[4,5‐c]quinoline‐1(2H)‐one ring skeleton, we were interested in identifying structural elements that contribute to the cytotoxicity of this class of compounds. The effect of several quinoline‐ring substituents was examined and the new compounds were evaluated in vitro for cytotoxicity against three human cancer cell lines namely, lung fibrosarcoma
作为我们基于最近报道的嘧啶基 [4,5-c] 喹啉 - 1 (2H) - 单环骨架开发新型抗有丝分裂剂的持续研究工作的一部分,我们有兴趣确定有助于这种细胞毒性的结构元素类化合物。检查了几种喹啉环取代基的作用,并在体外评估了新化合物对三种人类癌细胞系的细胞毒性,即肺纤维肉瘤 HT-1080、结肠腺癌 HT-29 和乳腺癌 MDA-MB-231。大多数化合物在低微摩尔和亚微摩尔范围内显示出细胞毒活性。构效关系信息表明可能涉及电子和空间因素的组合。对 HT ‐ 1080 细胞进行的流式细胞术细胞周期分析显示,细胞毒性最强的化合物 48、
