The antipyretic potential of viscosine, a natural product isolated from the medicinal plant , was investigated using yeast-induced pyrexia rat model, and its structure-activity relationship was investigated through molecular docking analyses with the target enzymes cyclooxygenase-1 (COX-1), cyclooxygenase-2 (COX-2), and microsomal prostaglandin E synthase-1 (mPGES-1). The in vivo antipyretic experiments showed a progressive dose-dependent reduction in body temperatures of the hyperthermic test animals when injected with viscosine. Comparison of docking analyses with target enzymes showed strongest bonding interactions (binding energy -17.34 kcal/mol) of viscosine with the active-site pocket of mPGES-1. These findings suggest that viscosine shows antipyretic properties by reducing the concentration of prostaglandin E in brain through its mPGES-1 inhibitory action and make it a potential lead compound for developing effective and safer antipyretic drugs for treating fever and related pathological conditions.
使用酵母诱导发热大鼠模型研究了从药用植物中分离出的天然产物粘菌素的解热潜力,并通过与靶酶环氧合酶-1(COX-1)、环氧合酶-2(COX-2)和微粒体前列腺素E合酶-1(mPGES-1)进行分子对接分析来研究其构效关系。体内解热实验表明,给发热实验动物注射粘菌素后,其体温呈剂量依赖性逐渐降低。与靶酶的对接分析比较显示,粘菌素与mPGES-1的活性位点口袋具有最强的结合相互作用(结合能-17.34 kcal/mol)。这些发现表明,粘菌素通过其对mPGES-1的抑制作用降低脑中前列腺素E的浓度而表现出解热特性,使其成为开发治疗发热及相关病理状况的有效且更安全的解热药物的潜在先导化合物。
