agents designated as N-phenyl 4-(2-oxoimidazolidin-1-yl)benzenesulfonates (PIB–SOs) and phenyl 4-(2-oxoimidazolidin-1-yl)benzenesulfonamides (PIB–SAs). Our previous structure-activity relationship studies (SAR) focused on the aromatic ring B of PIB-SOs and PIB-SAs leaving the impact of the phenylimidazolidin-2-one moiety (ring A) on the binding to the colchicine-binding site (C-BS) poorly studied. Therefore
我们最近设计并制备了新的有效抗微管剂家族,命名为N4-(2-氧代咪唑啉-1-基)苯磺酸苯酯(PIB-SOs)和4-(2-氧代咪唑啉-1-基)苯磺酰胺(PIB-SAs)。我们之前的结构活性关系研究(SAR)专注于PIB-SO和PIB-SA的芳香环B,而苯基咪唑啉二-2-酮部分(环A)对秋水仙碱结合位点的结合(C -BS)学习得不好。因此,本研究的目的是评估由吡咯烷-2-酮部分取代咪唑烷-2--2-酮(IMZ)的效果。为此,设计,制备了15种新的4-(2-氧杂吡咯烷-1-基)苯磺酸苯基酯(PYB-SO)和15种苯基4-(2-氧杂吡咯烷-1-基)苯磺酸酰胺(PYB-SA)衍生物,化学表征和生物学评估。PYB-SO和PYB-SA在低纳摩尔至低微摩尔范围内显示抗增殖活性(0。在人HT-1080,HT-29,M21和MCF7癌细胞系上分别为0087–8.6μM和0.056–21μM)。而且,它们阻断了G2
