A series of novel 3-alkyl-1,5-diaryl-1H-pyrazoles were synthesized as combretastatin A-4 (CA-4) analogues and evaluated for antiproliferative activity against three human cancer cell lines (SGC-7901, A549 and HT-1080). Most of the target compounds displayed moderate to potent antiproliferative activity, and 7k was found to be the most potent compound. Structure-activity relationships indicated that
合成了一系列新型的3-烷基-1,5-二芳基-1H-吡唑类化合物,作为康布雷他汀A-4(CA-4)类似物,并评估了其对三种人类癌细胞系(SGC-7901,A549和HT- 1080)。大多数目标化合物都显示出中等至有效的抗增殖活性,而7k是最有效的化合物。构效关系表明,在吡唑骨架的N-1位带有三甲氧基苯基A环的化合物比在C-5位带有A环的化合物更有效。微管蛋白聚合和免疫染色实验表明,7k以类似于CA-4的方式有效抑制微管蛋白聚合并破坏微管蛋白微管动力学。
