With the view of developing novel apoptosis‐inducing agents against malignant cells, nicotinamide derivatives containing substituted O‐benzoyl‐tyrosine, dopamine, and norepinephrine residues were synthesized. Antiproliferative activity measurements using leukemia U937 cells revealed that the benzoyl‐tyrosine derivative having two hydroxys at C‐2 and C‐3 on the benzoyl group, and the one having a hydroxy
为了开发针对恶性细胞的新型凋亡诱导剂,合成了包含取代的O-苯甲酰基酪氨酸,多巴胺和去甲肾上腺素残基的烟酰胺衍生物。使用白血病U937细胞进行的抗增殖活性测量表明,苯甲酰基酪氨酸衍生物在C-2和C-3的苯甲酰基上有两个羟基,而在C-2羟基和C-4上有甲氧基的那个被证明是最多的。在9种烟酰胺衍生物中有效。IC 50这些化合物的值分别为0.87和3.15 µM,表明它们与表没食子儿茶素没食子酸酯相比具有显着的活性,没食子儿茶素没食子酸酯是绿茶中的儿茶素成分,以其显着的活性而闻名。琼脂糖凝胶电泳和染料染色证实细胞死亡过程是细胞凋亡的结果,表明这些化合物作为诱导细胞凋亡的抗癌剂具有很高的潜力。Drug Dev Res 72:289–297,2011.©2010 Wiley-Liss,Inc.
