it was significantly less cytotoxic to non-tumor cells. On acute leukemia cells, sulfonamide DFS16 activated intrinsic and extrinsic apoptosis with Bax/Bcl-2 inversion, increased FasR expression and ΔΨm loss. In K562, DFS16 induced apoptosis by caspase-3 activation, while in Jurkat, it induced AIF release and caspase-3 independent apoptosis. In multiple myeloma, DFS16 induced cell cycle arrest at the
当前可获得的针对血液系统恶性肿瘤的化学治疗药物具有多种不良反应,并且与高死亡率相关。因此,在这项研究中,我们评估了26种新的磺酰胺衍生物对急性白血病和多发性骨髓瘤细胞的细胞毒性作用,以试图发现一种可以用作新化学治疗剂原型的新的选择性和安全化合物。最具细胞毒性的化合物DFS16以浓度和时间依赖性方式降低K562,Jurkat和MM.1S细胞的细胞活力,并且对非肿瘤细胞的细胞毒性明显降低。在急性白血病细胞上,磺酰胺DFS16通过Bax / Bcl-2倒置激活FasR表达和ΔΨm丢失,从而激活内在和外在凋亡。在K562中DFS16通过激活caspase-3诱导凋亡,而在Jurkat中,它诱导AIF释放和caspase-3独立凋亡。在多发性骨髓瘤中,DFS16诱导细胞周期停滞在G2 / M期,并伴随ΔΨm丢失而凋亡。总之,结果表明,新的磺酰胺衍生物DFS16在急性白血病和多发性骨髓瘤细胞中诱导凋亡
