indole-benzimidazole structures have recently gained considerable interest because of their anticancer properties and estrogen receptor (ER) modulatory actions. In this study, novel methylsulfonyl indole-benzimidazole derivatives have been synthesized upon substitution of respectively the first (R1) and fifth (R2) positions of benzimidazole and indole groups. Structure and activityrelationships were then studied
癌症带来了全球性的医疗保健问题,需要选择性和有效的治疗方案。为了解决这个问题,在药物化学领域中正在研究大量的治疗候选物。因此,由于吲哚-苯并咪唑的抗癌特性和雌激素受体(ER)的调节作用,近来引起了人们的极大兴趣。在这项研究中,已经分别取代了苯并咪唑和吲哚基团的第一(R 1)和第五(R 2)位,合成了新的甲基磺酰基吲哚-苯并咪唑衍生物。然后通过 1 H NMR,13 C NMR,质谱和计算机分析研究结构和活性之间的关系对接分析以及细胞活力测量。我们发现这些化合物对ERα(ERα)表现出相当高的亲和力。另外,乙基和甲基磺酰基吲哚-苯并咪唑之间的细胞毒性谱的相关性分析揭示了有效和一致的R 1和R 2取代的集合。但是,对于某些候选衍生物,其独特的细胞毒性水平和生存能力与整个研究过程中都观察到ERα亲和力相关性,这表明磺酰基侧链修饰本身也可以影响ERα结合水平。这些结果表明,我们新颖的甲基磺酰基吲哚

Several 5-(alkylsulfonyl)-1-substituted-2-(1H-pyrrol-2-yl)-1H-benzo[d]imidazole derivatives were synthesized and their antioxidant activities were investigated using lipid peroxidation (LPO) and 7-ethoxyresorufin O-deethylase (EROD) assays. Docking analysis with Human NAD[P]H-Quinone oxidoreductase 1 (NQO1) was also performed to gather thorough information about these compounds that have antioxidant activities. Moreover, their molecular descriptors and ADME properties were calculated using the SwissADME online program. As a result, most of our compounds possessed better affinity and created ample interactions with NQO1. The most potent compound 5j had LP inhibition value of 3.73 nmol/mg/min. Other compounds exhibited moderate activity on LP levels comparing to standard butylated hydroxy toluene (BHT). However, the inhibitory effect on EROD activity was not significant.
