techniques. Most of the compounds exhibited promising antibacterial activity, in particular Gram-positive bacteria. The anti-inflammatory assay was evaluated against protein denaturation as well as HRBC membrane stabilization methods and compounds exhibit excellent anti-inflammatory activity in both methods. Molecular docking study has been performed for all the synthesized compounds with S. aureus dihydropteroate
已开发出一种绿色,环保,高效的方案,并通过多组分反应(MCR)合成了一系列基于香豆素的吡喃并[2,3- c ]吡唑衍生物(3)。通过化合物(3)在酸性条件下的反应,分离出意外的3-香豆基-3-吡唑基丙酸(4)。此外,化合物(4)的分子内环化导致C 4 C 4色子(9),然后使用多种技术筛选这些化合物的生物学活性。大多数化合物表现出有希望的抗菌活性,特别是革兰氏阳性细菌。评估了抗炎测定的抗蛋白质变性以及HRBC膜稳定化方法,化合物在这两种方法中均表现出出色的抗炎活性。已经用金黄色葡萄球菌二氢蝶呤合成酶(DHPS)对所有合成的化合物进行了分子对接研究,获得的结果是很有希望的。
