via [3 + 2]-cycloaddition of pyridinium ylides to 1-chloro-2-nitrostyrenes. The synthesized molecules were evaluated for antiproliferative activities against a BE(2)-C neuroblastoma cell line with several compounds decreasing the viability of cancer cells. Indolizine 9db showed higher potency than that of all-trans-retinoic acid, an approved cancer drug. Mechanistically, it was found to inhibit tubulin
中氮茚和吡唑并[1,5- a ]吡啶是通过吡啶鎓叶立德与1-氯-2-硝基苯乙烯的[3+2]-环加成反应制备的。评估了合成分子对 BE(2)-C 神经母细胞瘤细胞系的抗增殖活性,其中几种化合物可降低癌细胞的活力。中氮茚9db显示出比全反式视黄酸(一种已批准的抗癌药物)更高的效力。从机制上讲,它被发现可以抑制微管蛋白聚合,因此提出可以利用所发现的化学物质来开发新型微管靶向抗癌剂。
