An array of furanylarylene arylsulfonylindolesulfonamides was synthesized through multi-step synthetic protocols involving bromination, stannylation, Stille cross coupling, reduction, arylsulfonylation, chlorosulfonylation, and condensation reactions. As a preliminary evaluation, these analogs were tested for antibacterial activity against a series of bacterial strains such as Bacillus subtilis, Enterococcus faecalis, Staphylococcus aureus, Pseudomonas aeruginosa, Escherichia coli, and Klebsiella pneumoniae using a two-fold serial dilution assay. Whereas analogs possessing unsubstitution, bromosubstitution, or methyl substitution on the benzene ring of benzenesulfonyl group were less active/inactive, the methoxy and chloro substituted counterparts were demonstrated to be comparatively more active. A few of them were found to exhibit better activity than the standard, streptomycin against selective organisms.
通过涉及溴化、链烷化、Stille 交叉偶联、还原、芳基磺酰化、氯磺酰化和缩合反应的多步合成方案,合成了一系列呋喃芳基芳基磺酰基吲哚磺酰胺。作为初步评估,我们采用两倍序列稀释法测试了这些类似物对一系列细菌菌株(如枯草杆菌、粪肠球菌、金黄色葡萄球菌、铜绿假单胞菌、大肠埃希菌和肺炎克雷伯菌)的抗菌活性。苯磺酰基苯环上未取代、溴取代或甲基取代的类似物活性较低,甲氧基和氯取代的类似物活性相对较高。研究发现,与标准链霉素相比,其中一些药物对选择性生物的活性更好。
