New derivatives of two isomeric types of azaphenothiazines, 1,8- and 2,7-diazaphenothiazine, containing the triple bond substituents and additionally tertiary cyclic and acyclic amine groups, were synthesized and tested for their anticancer activity. The compounds exhibited differential inhibitory activities. Better results were obtained when the acetylenic group was transformed via the Mannich reaction
合成了两个异构类型的氮杂吩噻嗪的新衍生物,分别包含三键取代基以及另外的叔环状和无环胺基的1,8-和2,7-二氮杂吩噻嗪,并测试了它们的抗癌活性。该化合物表现出不同的抑制活性。当炔基经由曼尼希反应转化为二烷基氨基丁炔基时,获得了更好的结果。活性最高的是2,7-二氮杂吩噻嗪,其具有针对人导管乳腺上皮肿瘤细胞系T47D的N-甲基哌嗪-2-丁炔基取代基,比顺铂更有效。结果证明2,7-二氮杂吩噻嗪系统比同分异构的1,8-二氮杂1更具活性。对于活性最高的化合物,通过RT-QPCR方法检测TP53,CDKN1A,BCL-2和BAX基因的表达。基因表达比BACL-2 / BAX表明T47D细胞中的线粒体凋亡。合成使得获得许多具有二烷基氨基炔基取代基的新的生物活性吩噻嗪成为可能,所述二烷基氨基炔基取代基将各种叔环状和非环状胺部分插入取代基中。
