Abstract

Neprilysin (NEP) is a neutral endopeptidase with diverse physiological roles in the body. NEP's role in degradation of diverse classes of peptides such as amyloid beta, natriuretic peptide, substance P, angiotensin, endothelins, etc., is associated with pathologies of alzheimer's, kidney and heart diseases, obesity, diabetes and certain malignancies. Hence, the functional inhibition of NEP in the above systems can be a good therapeutic target. In the present study, drug repurposing approach was used to identify NEP inhibitors. Molecular docking was carried out using GLIDE tool. 2934 drugs from the ZINC12 database were screened using high throughput virtual screening (HTVS) followed by standard precision (SP) and extra precision (XP) docking. Based on the XP docking score and ligand interaction, the top 8 hits were subjected to free ligand binding energy calculation, to filter out 4 hits (ZINC000000001427, ZINC000001533877, ZINC000000601283, and ZINC000003831594). Further, induced fit docking-standard precision (IFD-SP) and molecular dynamics (MD) studies were performed. The results obtained from MD studies suggest that ZINC000000601283-NEP and ZINC000003831594-NEP complexes were most stable for 20ns simulation period as compared to ZINC000001533877-NEP and ZINC000000001427-NEP complexes. Interestingly, ZINC000000601283 and ZINC000003831594 showed similarity in binding with the reported NEP inhibitor sacubitrilat. Findings from this study suggest that ZINC000000601283 and ZINC000003831594 may act as NEP inhibitors. In future studies, the role of ZINC000000601283 and ZINC000003831594 in NEP inhibition should be tested in biological systems to evaluate therapeutic effect in NEP associated pathological conditions.

摘要

中性肽链内切酶(NEP)是一种在体内具有多种生理作用的中性内肽酶。NEP在降解多种肽类物质(如β-淀粉样蛋白、利钠肽、P物质、血管紧张素、内皮素等)方面的作用与阿尔茨海默病、肾脏疾病、心脏病、肥胖症、糖尿病和某些恶性肿瘤的病理状况相关。因此,在上述系统中对NEP进行功能抑制可能是一个良好的治疗靶点。在本研究中,采用药物重新利用方法来鉴定NEP抑制剂。使用GLIDE工具进行分子对接。使用高通量虚拟筛选(HTVS)对ZINC12数据库中的2934种药物进行筛选,随后进行标准精度(SP)和高精度(XP)对接。基于XP对接分数和配体相互作用,对排名前8的命中物进行游离配体结合能计算,以筛选出4种命中物(ZINC000000001427、ZINC000001533877、ZINC000000601283和ZINC000003831594)。此外,还进行了诱导契合对接-标准精度(IFD-SP)和分子动力学(MD)研究。MD研究获得的结果表明,与ZINC000001533877-NEP和ZINC000000001427-NEP复合物相比,ZINC000000601283-NEP和ZINC000003831594-NEP复合物在20纳秒的模拟期内最稳定。有趣的是,ZINC000000601283和ZINC000003831594在与已报道的NEP抑制剂沙库巴曲缬沙坦结合方面表现出相似性。本研究结果表明,ZINC000000601283和ZINC000003831594可能作为NEP抑制剂。在未来的研究中,应在生物系统中测试ZINC000000601283和ZINC000003831594在抑制NEP方面的作用,以评估其在NEP相关病理状况下的治疗效果。
