series of shikonin derivatives (1–13) that were acylated selectively by various thiophene or indol carboxylic acids at the side chain of shikonin were synthesized, and their biological activities were also evaluated as potential tubulin inhibitors. Among them, compound 3 ((R)‐1‐(5,8‐dihydroxy‐1,4‐dioxo‐1,4‐dihydronaphthalen‐2‐yl)‐4‐methylpent‐3‐enyl 3‐(1H‐indol‐3‐yl)propanoate) and compound 8 ((R)‐1‐(5,8‐dihydroxy‐1
一系列紫草素衍生物(1 - 13),其被选择性地通过各种噻吩或吲哚羧酸的紫草素的侧链酰化合成,以及它们的生物活性也进行了评价作为潜在的微管蛋白抑制剂。其中,化合物3((R)-1-(5,8-二羟基-1,4-二氧代-1,4-二氢萘-2-基)-4-甲基戊-3-烯基3-(1 H-吲哚-3-基)丙酸酯)和化合物8((R)-1-(5,8-二羟基-1,4-二氧代-1,4-二氢萘-2-基)-4-甲基戊-3-烯基2- (噻吩-3-基)乙酸甲酯)表现出良好的A875的抗增殖活性(IC 50 = 0.005±0.001μ米,0.009±0.002μ米)和HeLa(IC 50 = 11.84±0.64μ米,4.62±0.31μ米)癌细胞系在体外分别。紫草素(IC 50 = 0.46±0.002μ米,4.80±0.48μ米)和秋水仙素(IC 50 = 0.75±0.05μ米,17.79±0.76μ米)作为引
