摘要

耐多药微生物感染的出现影响了传染病的治疗。由于临床长期使用抗菌药物,微生物对临床药物产生耐药性。为了充分利用这些化学家族的潜力,采用环保的高产方法制备了几种含对甲苯磺酰胺(TPS)的噻吩衍生物。这些合成衍生物具有广泛的结构多样性,显示出结构-活性联系。在多组分反应(MCR)中,通用反应物(1mmol)在pH 7.2±0.2和温度70±1℃下反应6-8小时。该反应采用可重复使用的有机催化剂l-脯氨酸(1mol %),并通过Knoevenagel缩合途径进行反应,该缩合途径具有有效生成所述噻吩衍生物(TD)的优点。然后,进一步将TD与对甲苯磺酰胺(toyl - cl)在0℃下反应10-12 h,得到最终产物TPS。本研究提供了一种廉价和环保的TPS衍生物的方法。仔细阅读表格表明,与大肠杆菌和金黄色葡萄球菌相比,TPS衍生物对鼠伤寒沙门氏菌表现出有希望的活性。具有良好活性的化合物在酰胺氨基部分的苯甲醛苯环上含有吸电子和给电子取代基。图示:多组份杂环芳基磺胺反应的绿色可持续发展

Synthesis of sustainable heterocyclic aryl sulfonamide derivatives: computational studies, molecular docking, and antibacterial assessment

The treatment of infectious diseases is impacted by the emergence of multidrug-resistant microbiological infections. Due to the long-term usage of antibacterial clinical drugs, microbes develop resistance to clinical drugs. To take advantage of the potential of these families of chemicals, several derivatives of thiophene containing p-toluene sulfonamide (TPS) were prepared using an eco-friendly method with high yields. These synthetic derivatives had a wide range of structural diversity to demonstrate a structure–activity link. In multi-component reaction (MCR), the versatile reactants (1 mmol) react for up to 6–8 h at pH 7.2 ± 0.2 and temperature 70 ± 1 °C. The reaction involved the reusable organic catalyst l-Proline (1 mol%), and the mechanisms through a Knoevenagel condensation pathway, which has the advantage of effectively producing the described thiophene derivatives (TD). Then, further TD reacts with p-toluene sulfonamide (Tosyl-Cl) at 0 °C within 10–12 h to provide the final product TPS. The present investigation provides an inexpensive and eco-friendly method of TPS derivatives. A perusal of the tables indicates that TPS derivatives exhibited promising activity against S. typhimurium as compared to E. coli and S. aureus. The compounds having good activity contained electron-withdrawing as well as electron-donating substituent groups on the benzaldehyde benzene ring of the amino part of the amide.
