在这项研究中,来自灵芝的一系列次级代谢产物。针对金黄色葡萄球菌蛋白靶标进行筛选,包括磷酸转乙酰酶,结块因子A,和二氢叶酸还原酶,使用分子对接模拟。与目标蛋白的结合能最强的化学物质是灵芝三醇,LucidumolB,灵芝酸J,麦角固醇,麦角甾醇过氧化物,7-氧代蒽酸Z,灵芝酸AM1,灵芝酸D,和24R-ergosta-7,2E-二烯-3β,5α,6β-三醇。有趣的是,灵芝苷A对蛋白质凝集因子A的亲和力最大,结果通过分子动力学模拟验证。此外,三种天然灵芝。从越南中部KonKaKinh国家公园收集灵芝VNKKKK1903,灵芝灵芝VNKK1905A2和亚麻黄病VNKKK1904等菌株,并使用琼脂扩散技术评估其对金黄色葡萄球菌的抗菌活性。这些结果表明,真菌提取物和次生代谢产物可以作为抗金黄色葡萄球菌的有价值的抗生素来源。这些发现为进一步探索灵芝化合物的抗菌机制提供了重要的科学基础。在未来的研究中。
In this study, a series of secondary metabolites from Ganoderma sp. were screened against Staphylococcus aureus protein targets, including as phosphotransacetylase, clumping factor A, and dihydrofolate reductase, using molecular docking simulations. The chemicals that showed the strongest binding energy with the targeted proteins were ganodermanontriol, lucidumol B, ganoderic acid J, ergosterol, ergosterol peroxide, 7-oxoganoderic acid Z, ganoderic acid AM1, ganosinoside A, ganoderic acid D, and 24R-ergosta-7,2E-diene-3β,5α,6β-triol. Interestingly, ganosinoside A showed the greatest affinity for the protein clumping factor A, a result validated by molecular dynamic simulation. Additionally, three natural Ganoderma sp. Strains as Ganoderma lingzhi VNKKK1903, Ganoderma lingzhi VNKK1905A2, and Amauroderma subresinosum VNKKK1904 were collected from Kon Ka Kinh National Park in central land of Vietnam and evaluated for their antibacterial activity against Staphylococcus aureus using an agar well diffusion technique. These results suggest that the fungal extracts and secondary metabolites may serve as valuable sources of antibiotics against Staphylococcus aureus. These findings provided an important scientific groundwork for further exploration of the antibacterial mechanisms of compounds derived from Ganoderma sp. in future research.
