N-(4-烷基-5-苄基噻唑-2-基)氨基烷酰胺及其盐的抗肿瘤活性
1.抗肿瘤活性原理
MTT法生物活性测试又称MTT比色法,是一种检测细胞存活和生长的方法。MTT分析法以活细胞代谢物还原剂噻唑蓝[3-(4,5-二甲基-2-噻唑)-2,5-二苯基溴化四氮唑;3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide,MTT]为基础。MTT是一种能接受氢原子的染料。活细胞线粒体中与NADP相关的脱氢酶在细胞内可将黄色的MTT转化成不溶性的蓝紫色的甲瓒(formazon),而死细胞则无此功能。用DMSO溶解formazon后,在一定波长下用酶标仪测定光密度值,既可定量测出细胞的存活率。根据光密度值的变化观察样品对肿瘤细胞的抑制作用。
2.抗肿瘤活性实验
试样:N-(4-烷基-5-苄基噻唑-2-基)氨基烷酰胺和N-(4-烷基-5-苄基噻唑-2-基)卤代烷酰胺及其盐。
