Synthesis of a series of novel cyano- and amidinobenzothiazole derivatives 3−31 is described. All studied amidino derivatives showed noticeable antiproliferative effect on several tumor cell lines. Cyano derivatives 11−17 showed considerably less pronounced activity because of their poor solubility in aqueous cell culture medium, which was confirmed by the principal components (PC) analysis.

的一系列新颖的氰基和amidinobenzothiazole衍生物的合成3 - 31进行说明。所有研究的a基衍生物对几种肿瘤细胞系均显示出显着的抗增殖作用。氰基衍生物11 - 17显示,因为它们在水溶液细胞培养基的溶解性差,这是由主要成分(PC)分析证实的显着较不显着的活性。化合物21,22,28,和29对它们对细胞周期和细胞凋亡,从而影响测试22和29具有在吡啶环的C-6位上的甲基的C3,显示出剧烈的细胞周期扰动,其与浓度和时间有关,并诱导细胞凋亡。基于物化指标和测得的生物活性的QSAR建模表明了分子极化率的相关性以及药效团在分子表面上的活性的特定分布。总之,含有异丙基d基或咪唑基的苯并噻唑将被视为进一步研究铅鉴定的起始化合物。
