Colchicine binding site inhibitors (CBSIs) are potential microtubule targeting agents (MTAs), which can overcome multidrug resistance, improve aqueous solubility and reduce toxicity faced by most MTAs. Novel tetrahydroquinoxaline sulfonamide derivatives were designed, synthesized and evaluated for their antiproliferative activities. The MTT assay results demonstrated that some derivatives exhibited
秋水仙碱结合位点抑制剂(CBSI)是潜在的微管靶向剂(MTA),它可以克服多药耐药性,提高水溶性并降低大多数 MTA 面临的毒性。设计、合成了新型四氢喹喔啉磺酰胺衍生物并评估了其抗增殖活性。MTT测定结果表明,一些衍生物对HT-29细胞系表现出中度至强度的抑制活性。其中,化合物I-7是最活跃的化合物。此外,I-7抑制微管蛋白聚合,扰乱微管网络,破坏有丝分裂纺锤体的形成并将细胞周期阻滞在 G2/M 期。然而,I-7不诱导细胞凋亡。此外,ADME 的预测表明I-7显示出良好的理化和药代动力学特性。详细的分子对接证实I-7通过氢和疏水相互作用靶向秋水仙碱位点。
