diarylpyrazoles were designed as potential microtubule targeting agents. Twenty-eight target compounds were synthesized and exhibited potent antiproliferative activity. Compound 15e, displayed potent antiproliferative activity against SGC-7901, KB and HT-1080 cell lines, respectively, and was comparable to the positive control, CA-4. Tubulin polymerization experiments indicated that 15e effectively
设计了两个系列的二芳基吡唑类作为潜在的微管靶向剂。合成了28种目标化合物,并显示出有效的抗增殖活性。化合物15e分别显示出对SGC-7901,KB和HT-1080细胞系的有效抗增殖活性,与阳性对照CA-4相当。微管蛋白聚合实验表明15e有效抑制微管蛋白聚合,免疫染色测定表明它显着破坏了微管蛋白的微管动力学。此外,细胞周期研究表明,化合物15e在G2 / M期显着阻止了细胞周期进程,并导致微管失稳。分子建模研究表明15e 可以与微管上的秋水仙碱结合位点结合。
