is famous for its addictive effect. On the other hand, this plant has good potential as an antioxidant agent, and so far, it was not explicitly explained what the most contributing compound in the leaves to that activity is. This study has been conducted using several computational methods to determine which compounds are the most active in interacting with cytochrome P450, myeloperoxidase, and NADPH oxidase proteins. First, virtual screening was carried out based on molecular docking, followed by profiling the properties of adsorption, distribution, metabolism, excretion, and toxicity (ADMET); the second one is the molecular dynamics (MD) simulations for 100 ns. The virtual screening results showed that three compounds acted as inhibitors for each protein: (-)-epicatechin, sitogluside, and corynoxeine. The ADMET profiles of the three compounds exhibit good drug ability and toxicity. The trajectories study from MD simulations predicts that the complexes of these three compounds with their respective target proteins are stable. Furthermore, these compounds identified in this computational study can be a potential guide for future experiments aimed at assessing the antioxidant properties through testing.
它以成瘾性作用而闻名。另一方面,这种植物作为抗氧化剂具有良好的潜力,到目前为止,尚未明确解释叶片中对该活性贡献最大的化合物是什么。本研究使用了几种计算方法来确定哪些化合物在与细胞色素P450、髓过氧化物酶和NADPH氧化酶蛋白相互作用时最具活性。首先,基于分子对接进行虚拟筛选,随后对吸附、分布、代谢、排泄和毒性(ADMET)特性进行分析;第二个是进行100纳秒的分子动力学(MD)模拟。虚拟筛选结果表明,三种化合物对每种蛋白质都起到抑制剂的作用:(-)-表儿茶素、谷甾糖苷和育亨宾碱。这三种化合物的ADMET谱显示出良好的药物性能和毒性。MD模拟的轨迹研究预测,这三种化合物与其各自靶蛋白的复合物是稳定的。此外,在这项计算研究中鉴定出的这些化合物可以为未来旨在通过测试评估抗氧化特性的实验提供潜在指导。
