Abstract

Lymphatic filariasis is one of the major diseases that belong to the category of neglected tropical illness. Filarial nematodes are the cause of the disease and are transmitted to humans via blood-feeding arthropod vectors. Drugs such as Albendazole, Ivermectin and diethylcarbamazine are administered either individually or in combination to overcome the progress of the lymphatic filariasis. These drugs have some minor side effects like temporary hair loss, dizziness, nausea etc. The filarial parasites have multifunctional proteins including the Glutathione-s-transferase (GST) enzyme. This study aims at the identification of a natural molecule that has the potential to bind with the GST enzyme, which plays a major role in detoxification of endogenous electrophilic compounds. Thus the binding interrupts the detoxification process within the filarial parasite, . A medicinal plant , owing to its anthelmintic properties was searched for the presence of potential phytocompounds. The phytocompounds were docked against the homology modeled GST enzyme using the MOE software. The results were screened and analyzed based on the Lipinski rule of 5. N-octanoate was the phytocompound obtained based on molecular docking, subjected to molecular dynamics. These results require further in vitro and in vivo validation to consider n-octanoate as a potential drug candidate for lymphatic filariasis treatment.

摘要

淋巴丝虫病是被忽视的热带疾病中的主要疾病之一。丝虫线虫是该疾病的病因,通过吸血节肢动物媒介传播给人类。阿苯达唑、伊维菌素和乙胺嗪等药物单独或联合使用,以控制淋巴丝虫病的病情发展。这些药物有一些轻微的副作用,如暂时性脱发、头晕、恶心等。丝虫寄生虫具有多种功能蛋白,包括谷胱甘肽 - S - 转移酶(GST)。本研究旨在鉴定一种天然分子,该分子有可能与GST酶结合,GST酶在内源性亲电化合物的解毒过程中起主要作用。因此,这种结合会中断丝虫寄生虫体内的解毒过程。由于其驱虫特性,研究人员在一种药用植物中寻找潜在的植物化合物。使用MOE软件将这些植物化合物与同源建模的GST酶进行对接。根据Lipinski的五规则对结果进行筛选和分析。基于分子对接获得的植物化合物正辛酸进行了分子动力学研究。这些结果需要进一步的体外和体内验证,才能将正辛酸视为治疗淋巴丝虫病的潜在候选药物。
