Multidrug-resistant infections have become a major public health concern globally. Inhibition of its essential MurF protein has been proposed as a potential target for broad-spectrum drugs. This study aimed to evaluate the potential of a novel ecological niche of 374 fungus-growing termite associated Natural Products (NPs). The molecular docking and computational pharmacokinetics screened four compounds, i.e., Termstrin B, Fridamycin A, Maduralactomycin A, and Natalenamide C, as potential compounds that have higher binding affinities and favourable protein-ligand interactions. The compound Maduralactomycin A induced more stability based on its lowest average RMSD value (2.31 Å) and low standard deviation (0.35) supported by the consistent flexibility and β-factor during the protein's time-dependent motion. While hydrogen bond analysis indicated that Termstrin B has formed the strongest intra-protein interaction, solvent accessibility was in good agreement with Maduralactomycin A compactness. Maduralactomycin A has the strongest binding energy among all the compounds (-348.48 kcal/mol) followed by Termstrin B (-321.19 kcal/mol). Since these findings suggest Maduralactomycin A and Termstrin B as promising candidates for inhibition of MurF protein, the favourable binding energies of Maduralactomycin A make it a more important compound to warrant further investigation. However, experimental validation using animal models and clinical trials is recommended before reaching any final conclusions.
多重耐药感染已成为全球主要的公共卫生问题。抑制其必需的MurF蛋白已被提议作为广谱药物的潜在靶点。本研究旨在评估374种与培菌白蚁相关的天然产物(NPs)新生态位的潜力。分子对接和计算药代动力学筛选出四种化合物,即Termstrin B、弗氏霉素A、马杜拉乳霉素A和纳塔伦酰胺C,作为具有更高结合亲和力和良好蛋白-配体相互作用的潜在化合物。化合物马杜拉乳霉素A基于其最低的平均均方根偏差值(2.31 Å)和低标准偏差(0.35)诱导了更高的稳定性,这在蛋白质随时间的运动过程中由一致的柔韧性和β因子所支持。虽然氢键分析表明Termstrin B形成了最强的蛋白内相互作用,但溶剂可及性与马杜拉乳霉素A的紧密性高度一致。马杜拉乳霉素A在所有化合物中具有最强的结合能(-348.48 kcal/mol),其次是Termstrin B(-321.19 kcal/mol)。由于这些发现表明马杜拉乳霉素A和Termstrin B是抑制MurF蛋白的有前景的候选物,马杜拉乳霉素A有利的结合能使其成为更重要的化合物,值得进一步研究。然而,在得出任何最终结论之前,建议使用动物模型和临床试验进行实验验证。
