Dengue virus NS2/NS3 protease because of its ability to cleave viral proteins is considered as an attractive target to screen antiviral agents. Medicinal plants contain a variety of phytochemicals that can be used as drug against different diseases and infections. Therefore, this study was designed to uncover possible phytochemical of different classes (Aromatic, Carbohydrates, Lignin, Saponins, Steroids, Tannins, Terpenoids, Xanthones) that could be used as inhibitors against the NS2B/NS3 protease of DENV. With the help of molecular docking, Garcinia phytochemicals found to be bound deeply inside the active site of DENV NS2B/NS3 protease among all tested phytochemicals and had interactions with catalytic triad (His51, Asp75, Ser135). Thus, it can be concluded from the study that these Gracinia phytochemicals could serve as important inhibitors to inhibit the viral replication inside the host cell. Further in-vitro investigations require confirming their efficacy.
登革病毒NS2/NS3蛋白酶因其能够切割病毒蛋白,被认为是筛选抗病毒药物的一个有吸引力的靶点。药用植物含有多种植物化学物质,可用于对抗不同的疾病和感染。因此,本研究旨在发现不同类别(芳香族、碳水化合物、木质素、皂苷、类固醇、单宁、萜类、呫吨酮)的可能植物化学物质,这些物质可作为登革病毒NS2B/NS3蛋白酶的抑制剂。借助分子对接,在所有测试的植物化学物质中,藤黄属植物的植物化学物质被发现深深结合在登革病毒NS2B/NS3蛋白酶的活性位点内,并与催化三联体(His51、Asp75、Ser135)相互作用。因此,从该研究可以得出结论,这些藤黄属植物的植物化学物质可作为重要的抑制剂,抑制宿主细胞内的病毒复制。进一步的体外研究需要确认它们的功效。
