A new class of nitrovinyl biphenyl compounds based on the structures of colchicines and allocolchicines were designed, synthesized, and shown to inhibit tubulin polymerization and cause mitotic arrest. A majority of these compounds were found to possess potent anticancer properties, with IC50 values in the range of 0.05–7 μM, and are equally potent with colchicine in HeLa and MCF‐7 cells. Compounds
设计,合成了基于秋水仙碱和二十碳五烯茶碱结构的新型一类硝基乙烯基联苯化合物,该化合物可抑制微管蛋白聚合并引起有丝分裂停滞。大多数这些化合物被发现具有有效的抗癌性质,带IC 50个中的0.05-7μ范围内的值中号,并且与在HeLa和MCF-7细胞秋水仙碱同等有效。化合物14e和14f抑制微管蛋白的组装超过60%,流式细胞仪研究表明,细胞周期的G 2 / M期细胞以浓度依赖的方式生长停滞。用14 f处理细胞导致细胞周期蛋白B1和极光激酶B mRNA水平的上调,这对应于细胞周期G 2 / M期的生长停滞(作为作用方式)。
