4-(ethoxycarbonyl)-5-(arylamino)thiazoles and 5-(arylamino)-4-carbamoylthiazoles, respectively, is described. In vitro cytotoxicity of a large number of derivatives of these compounds has been tested against several cell lines. The highest activities observed are associated with the presence of a 2-[[(N,N-diethylamino)ethyl]amino] substituent at C-2 and a fluorine atom at the C-7 position of the tricyclic planar
通过4-(乙氧基羰基)-5-(芳基氨基)噻唑和5-(芳基氨基)-4-氨基甲酰基噻唑的环化反应合成9-羟基-和9-(烷基氨基)噻唑并[5,4-b]喹啉的新方法进行说明。这些化合物的大量衍生物的体外细胞毒性已经针对几种细胞系进行了测试。观察到的最高活性与在C-2处存在2-[[((N,N-二乙基氨基)乙基]氨基]取代基和在三环平面杂芳族骨架的C-7位置处的氟原子有关。三个结构特征似乎是抗肿瘤活性必不可少的:碳C-7处的正电荷密度,噻唑并喹啉骨架的C-2或C-9位置的侧链具有两个碱性氮和pKa值为7.5-10。最基本的中心,以及此基本侧链的构象灵活性。
