Complex microbial communities have been reported to be involved in endodontic infections. The microorganisms invade the dental pulp leading to pulpitis and initiating pulp inflammation. is a dominant bacterium implicated in both primary and secondary endodontic infections. Drugs targeting the molecular machinery of will minimize pulp infection. LpxA and LpxD are early acyltransferases involved in the formation of lipid A, a major component of bacterial membranes. The identification of leads which exhibit preference towards successive enzymes in a single pathway can also prevent the development of bacterial resistance. A stringent screening strategy utilizing physicochemical and pharmacokinetic parameters along with a virtual screening approach identified two compounds, Lomefloxacin and Enoxacin, with good binding affinity towards the early acyltransferases LpxA and LpxD. Lomefloxacin and Enoxacin, members of the fluoroquinolone antibiotic class, exhibit wide-ranging activity against diverse bacterial strains. Nevertheless, their effectiveness in the context of endodontic treatment requires further investigation. This study explored the potential of Lomefloxacin and Enoxacin to manage endodontic infections via computational analysis. Moreover, the compounds identified herein serve as a foundation for devising novel combinatorial libraries with enhanced efficacy for endodontic therapeutic strategies.
据报道,复杂的微生物群落与牙髓感染有关。微生物侵入牙髓,导致牙髓炎并引发牙髓炎症。[细菌名称]是一种在原发性和继发性牙髓感染中都起主要作用的细菌。针对[细菌名称]分子机制的药物将使牙髓感染降至最低。LpxA和LpxD是参与脂多糖A形成的早期酰基转移酶,脂多糖A是细菌细胞膜的主要成分。鉴定对单一途径中连续酶具有偏好性的先导化合物,也可以防止细菌耐药性的产生。一种利用物理化学和药代动力学参数以及虚拟筛选方法的严格筛选策略,确定了两种化合物,洛美沙星和依诺沙星,它们对早期酰基转移酶LpxA和LpxD具有良好的结合亲和力。洛美沙星和依诺沙星属于氟喹诺酮类抗生素,对多种细菌菌株具有广泛的活性。然而,它们在牙髓治疗中的有效性还需要进一步研究。本研究通过计算分析探索了洛美沙星和依诺沙星治疗牙髓感染的潜力。此外,本文鉴定的化合物为设计具有更高牙髓治疗策略疗效的新型组合文库奠定了基础。
