A series of novel 2‐amino‐3,4,5‐trimethoxybenzophenone analogues exhibited excellent activity as tubulin polymerization inhibitors by targeting the colchicine binding site of microtubules. The lead compound 17 exhibited an IC50 value of 1.6 μM, similar to that of combretastatin A‐4 (IC50=1.9 μM). It also displayed remarkable anti‐proliferative activity, with IC50 values ranging from 7–16 nM against
通过靶向微管的秋水仙碱结合位点,一系列新颖的2-氨基-3,4,5-三甲氧基二苯甲酮类似物表现出优异的微管蛋白聚合抑制剂活性。铅化合物17表现出的IC 50为1.6值μ中号,类似于考布他汀A-4的(IC 50 = 1.9μ中号)。它还显示出显着的抗增殖活性,IC 50值范围为7–16 n M对抗多种人类癌细胞系和一种MDR(+)癌细胞系。SAR信息表明,在二苯甲酮环A的C2位置和二苯甲酮环B的C3'位置引入氨基对最大化活性起着重要作用。
