Abstract

Ganoderma lucidum is a unique form of fungus utilized in Chinese medicine for various therapies as it exhibits a wide range of pharmacological activity. In this study, the purpose is to evaluate the possible drug-like qualities of the metabolites of G. lucidium as well as the impact that these metabolites have on the pathways involved in atherosclerosis. Throughout our research, a total of 17 compounds were chosen based on their drug-like properties. These compounds were then utilized in the subsequent networking and docking simulations. According to the findings, the compound ganodone has a maximum binding energy of -7.243 Kcal/mol. In terms of the binding energy, it has been discovered that the compound cianidanol has the lowest value. Based on the findings of the molecular docking investigations, it was determined that TNF, AKT1, SRC, and STAT3 exhibited a higher affinity for the complex. To determine this, molecular dynamics simulation was performed for about 100 nanoseconds. Following the completion of the GO functional analysis, it was discovered that the target genes were involved in the processes of protein binding, ATP binding, enzyme binding, and protein tyrosine kinase activity. Overall, the study results provide a view of possible metabolites that may have an impact on disease progression.

摘要

灵芝是一种独特的真菌,在中国医学中被用于各种治疗方法,因为它具有广泛的药理活性。在这项研究中,目的是评估灵芝代谢物可能具有的类药性,以及这些代谢物对动脉粥样硬化相关途径的影响。在我们的研究过程中,总共选择了 17 种基于其类药性的化合物。然后,这些化合物被用于随后的网络和对接模拟。根据研究结果,化合物 ganodone 的最大结合能为-7.243 Kcal/mol。就结合能而言,已发现化合物 cianidanol 的值最低。根据分子对接研究的结果,确定 TNF、AKT1、SRC 和 STAT3 对该复合物具有更高的亲和力。为此,进行了约 100 纳秒的分子动力学模拟。完成 GO 功能分析后,发现靶基因参与了蛋白质结合、ATP 结合、酶结合和蛋白酪氨酸激酶活性等过程。总的来说,该研究结果提供了可能影响疾病进展的代谢物的视角。
