Marine compounds with pyridoacridine skeletons are known to exhibit interesting antitumor activities. Among these compounds, meridine has already been reported as having significant antitumor activities in vitro. We synthesized 24 analogues of meridine substituted on ring A with the aim of obtaining compounds that display significantly higher in vitro antitumor activities than meridine. The 24 compounds
已知具有吡啶并r啶骨架的海洋化合物表现出令人感兴趣的抗肿瘤活性。在这些化合物中,已报道美定啶在体外具有显着的抗肿瘤活性。我们合成了在环A上取代的美利替丁的24个类似物,目的是获得比美替尼具有更高的体外抗肿瘤活性的化合物。在包括各种组织病理学类型(胶质母细胞瘤和乳腺癌,结肠癌,肺癌,前列腺癌和膀胱癌)在内的12种不同的人类癌细胞系中,以6种不同的浓度测试了24种化合物和美利替丁作为对照化合物。这25种化合物的IC(50)值(即,药物浓度将12个细胞系的平均生长值抑制了50%)超过5 log浓度,即10至0.0001 microM,其中四种化合物的体外抗肿瘤活性均比美定强。现在将对这些化合物进行进一步的药理研究,包括对常规鼠类肿瘤和移植到裸鼠上的人肿瘤的体内测试。
