pharmacokinetics and drug-likeness properties. Modification of the urea group by an amide group led to new PUB-SO analogs designated as N-phenyl amidobenzenesulfonates (PAB-SOs). The 2-chloroethyl moiety on ring A was also substituted by different alkyl, cycloalkyl and chloroalkyl groups. The new PAB-SOs and PUB-SOs blocking the cell cycle progression in S-phase exhibit antiproliferative activity in
N-苯基脲基苯磺酸盐(PUB-SOs)是一类新型的抗癌药物,可阻断S期细胞周期进程,诱导复制应激和DNA双链断裂(DSB)。在这项研究中,我们评估了修饰PUB-SOs环A上不同取代基的性质和位置对抗增殖活性,药理活性以及计算的理化,药代动力学和类药物性质的影响。尿素基团被酰胺基团修饰导致产生了新的PUB-SO类似物,称为N-苯基酰胺基苯磺酸盐(PAB-SOs)。环A上的2-氯乙基部分也被不同的烷基,环烷基和氯烷基取代。新的PAB-SOs和PUB-SOs在四种人类癌细胞系HT-1080,HT-29,HT-1080和HT-1080上,表现出亚微摩尔至低微摩尔范围(0.14-27μM)的抗增殖活性。 M21和MCF7。此外,选择的PUB-SO和PAB-SO衍生物可诱导M21细胞中H2AX的磷酸化,并且不表现出或仅表现出轻微的烷基化活性,如通过4-(4-硝基苄基)吡啶(NBP)分析所证实的。最后,
