Inflammation plays a pivotal role in various pathological processes, ranging from routine injuries and infections to cancer. Cyclooxygenase-2 (COX-2) and 5-lipoxygenase (5-LOX) are two major enzymes involved in the formation of lipid mediators of inflammation, such as prostaglandins and leukotrienes, through the arachidonic acid pathway. Despite the frequent use of nonsteroidal anti-inflammatory drugs for managing inflammatory disorders by inhibiting these enzymes, there is a wide spectrum of adverse effects linked to their usage. Jeevaneeya Rasayana (JR), a polyherbal formulation traditionally used in India, is renowned for its anti-inflammatory properties. The present study aimed to identify the potential phytocompounds in JR plants against COX-2 and 5-LOX, utilizing molecular docking and dynamic simulations. Among the 429 identified phytocompounds retrieved from publicly available data sources, Terrestribisamide and 1-(9Z-octadecenoyl)-sn-glycero-3-phosphoethanolamine have shown potential binding affinity and favorable interactions with COX-2 and 5-LOX arachidonic acid binding sites. The physicochemical properties and ADMET profiles of these compounds determined their drug-likeness and pharmacokinetics features. Additional validation using molecular dynamics simulations, SASA, Rg, and MM-PBSA binding energy calculations affirmed the stability of the complex formed between those compounds with target proteins. Together, the study identified the effectual binding potential of those bioactive compounds against COX-2 and 5-LOX, providing a viable approach for the development of effective anti-inflammatory medications.
炎症在各种病理过程中起着关键作用,从常规的损伤和感染到癌症。环氧化酶-2(COX-2)和 5-脂氧合酶(5-LOX)是参与形成炎症脂质介质的两种主要酶,如前列腺素和白三烯,通过花生四烯酸途径。尽管经常使用非甾体抗炎药通过抑制这些酶来治疗炎症性疾病,但它们的使用与广泛的不良反应有关。Jeevaneeya Rasayana(JR),一种传统上在印度使用的多草药配方,以其抗炎特性而闻名。本研究旨在利用分子对接和动态模拟,鉴定 JR 植物中针对 COX-2 和 5-LOX 的潜在植物化合物。在从公开可用数据源中检索到的 429 种鉴定的植物化合物中,Terrestribisamide 和 1-(9Z-十八碳烯酰基)-sn-甘油-3-磷酸乙醇胺显示出与 COX-2 和 5-LOX 花生四烯酸结合位点的潜在结合亲和力和有利相互作用。这些化合物的物理化学性质和 ADMET 概况决定了它们的药物相似性和药代动力学特征。使用分子动力学模拟、SASA、Rg 和 MM-PBSA 结合能计算进行的额外验证证实了这些化合物与靶蛋白形成的复合物的稳定性。总之,该研究确定了这些生物活性化合物对 COX-2 和 5-LOX 的有效结合潜力,为开发有效的抗炎药物提供了可行的方法。
