In this study, a series of secondary metabolites from Ganoderma sp. were screened against 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 24-ergosta-7,2-diene-3,5,6-triol. Interestingly, ganosinoside A showed the greatest affinity for the protein clumping factor A, a result validated by molecular dynamic simulation. Additionally, three natural sp. Strains as VNKKK1903 VNKK1905A2, and VNKKK1904 were collected from Kon Ka Kinh National Park in central land of Vietnam and evaluated for their antibacterial activity against using an agar well diffusion technique. These results suggest that the fungal extracts and secondary metabolites may serve as valuable sources of antibiotics against . These findings provided an important scientific groundwork for further exploration of the antibacterial mechanisms of compounds derived from sp. in future research.
在本研究中,利用分子对接模拟技术,对灵芝属的一系列次生代谢产物针对包括磷酸转乙酰酶、凝聚因子A和二氢叶酸还原酶在内的蛋白质靶点进行了筛选。与靶向蛋白结合能最强的化学物质有灵芝三醇、亮菌醇B、灵芝酸J、麦角甾醇、麦角甾醇过氧化物、7-氧代灵芝酸Z、灵芝酸AM1、灵芝糖苷A、灵芝酸D和24-麦角甾-7,2-二烯-3,5,6-三醇。有趣的是,灵芝糖苷A对蛋白质凝聚因子A表现出最大亲和力,这一结果通过分子动力学模拟得到了验证。此外,从越南中部的孔卡金国家公园采集了三个天然菌株VNKKK1903、VNKK1905A2和VNKKK1904,并采用琼脂孔扩散技术评估了它们对[此处原文缺失针对的对象]的抗菌活性。这些结果表明,真菌提取物和次生代谢产物可能是对抗[此处原文缺失针对的对象]的有价值抗生素来源。这些发现为未来研究中进一步探索灵芝属化合物的抗菌机制提供了重要的科学基础。
