Abstract

The rise in multidrug-resistant bacteria highlights the critical need for novel antibiotics. This study explores clovibactin-like compounds as potential therapeutic agents targeting lipid II, a crucial component in bacterial cell wall synthesis, using in silico techniques. A total of 2624 clovibactin analogs were sourced from the PubChem database and screened using ProTox 3.0 software based on their ADME-Tox properties, prioritizing candidates with favorable pharmacokinetic profiles and minimal toxicity. Molecular docking protocols were then employed to assess the binding interactions of the selected compounds with lipid II. Our analysis identified Compound 22 as a particularly promising candidate, exhibiting strong binding affinity, stable complex formation, and high selectivity for the target. Binding energy analysis, conducted via molecular dynamics simulations, revealed a highly negative value of -25.50 kcal/mol for Compound 22, surpassing that of clovibactin and underscoring its potential efficacy. In addition, Compound 22 was prioritized due to its exceptional binding affinity to lipid II and its favorable ADME-Tox properties, suggesting a lower likelihood of adverse effects. These characteristics position Compound 22 as a promising candidate for further pharmacological development. While our computational results are encouraging, experimental validation is essential to confirm the efficacy and safety of these compounds. This study not only advances our understanding of clovibactin analogs but also contributes to the ongoing efforts to combat antimicrobial resistance through innovative antibiotic development.

摘要

多重耐药细菌的增加凸显了对新型抗生素的迫切需求。本研究利用计算机技术探索类氯缬菌素化合物作为靶向脂 II 的潜在治疗剂,脂 II 是细菌细胞壁合成中的关键成分。总共从 PubChem 数据库中获取了 2624 种氯缬菌素类似物,并使用 ProTox 3.0 软件根据其 ADME-Tox 属性进行筛选,优先选择具有良好药代动力学特征和最小毒性的候选物。然后采用分子对接方案评估所选化合物与脂 II 的结合相互作用。我们的分析确定化合物 22 是一个特别有前景的候选物,表现出强结合亲和力、稳定的复合物形成以及对靶标的高选择性。通过分子动力学模拟进行的结合能分析显示,化合物 22 的结合能为 -25.50 kcal/mol,为高度负值,超过了氯缬菌素,突出了其潜在疗效。此外,化合物 22 因其对脂 II 的特殊结合亲和力和良好的 ADME-Tox 属性而被优先考虑,这表明其产生不良反应的可能性较低。这些特性使化合物 22 成为进一步药理开发的有前景的候选物。虽然我们的计算结果令人鼓舞,但实验验证对于确认这些化合物的疗效和安全性至关重要。这项研究不仅增进了我们对氯缬菌素类似物的理解,也为通过创新抗生素开发对抗抗菌药物耐药性的持续努力做出了贡献。
