Cardiovascular diseases (CVDs) are the leading cause of mortality worldwide. (Roxb. ex DC.) Wight & Arnot of the Combretaceae family is one of the most frequently approved and utilized medicinal trees in the traditional medicinal system, which was used for the treatment of a variety of diseases, including cardiovascular disorders. The present study aims to identify phytochemicals from , that do not exhibit any toxicity and have significant cardioprotective activity using an in-silico technique. Four different cardiovascular proteins, namely human angiotensin receptor (PDB ID: 4YAY), P38 mitogen-activated protein kinase (MAPK, PDB ID: 4DLI), 3-hydroxy-3-methylglutaryl-coenzyme A (HMG-Co A) reductase (PDB ID: 1HW9), and human C-reactive protein (PDB ID: 1B09), were used as target proteins to identify potential inhibitors using a virtual screening of the phytochemicals in revealed casuarinin as a potential inhibitor of all selected target proteins with strong binding energy. Furthermore, MD simulations for a 100 ns time scale also revealed that most of the key protein contacts of all target proteins were retained throughout the simulation trajectories. Binding free energy calculations using the MM-GBSA approach also support a strong inhibitory effect of casuarinin on target proteins. Casuarinin's effective binding to these proteins lays the groundwork for the development of broad-spectrum drugs as well as the understanding of the underlying mechanism against cardiovascular diseases through in vivo and clinical studies.
心血管疾病(CVDs)是全球范围内导致死亡的主要原因。使君子科诃子属(Roxb. ex DC.)植物是传统医学体系中最常被认可和使用的药用树木之一,用于治疗多种疾病,包括心血管疾病。本研究旨在利用计算机技术从诃子中鉴定出具有潜在心脏保护活性且无毒性的植物化学物质。我们选择了四种不同的心血管蛋白作为靶蛋白,包括人血管紧张素受体(PDB ID:4YAY)、P38 丝裂原活化蛋白激酶(MAPK,PDB ID:4DLI)、3-羟基-3-甲基戊二酰辅酶 A(HMG-CoA)还原酶(PDB ID:1HW9)和人 C 反应蛋白(PDB ID:1B09),利用植物化学物质的虚拟筛选来鉴定潜在的抑制剂。结果表明,诃子中的 CAS 可能是所有选定靶蛋白的潜在抑制剂,具有很强的结合能。此外,在 100 ns 的时间尺度上进行 MD 模拟也表明,在整个模拟轨迹中,所有靶蛋白的大多数关键蛋白接触都得到了保留。使用 MM-GBSA 方法进行的结合自由能计算也支持 CAS 对靶蛋白的强烈抑制作用。CAS 对这些蛋白的有效结合为开发广谱药物以及通过体内和临床研究了解针对心血管疾病的潜在机制奠定了基础。
