Cardiovascular diseases, including heart failure, stroke, and hypertension, affect 608 million people worldwide and cause 32% of deaths. Combination therapy is required in 60% of patients, involving concurrent Renin-Angiotensin-Aldosterone-System (RAAS) and Neprilysin inhibition. This study introduces a novel multi-target in-silico modeling technique (mt-QSAR) to evaluate the inhibitory potential against Neprilysin and Angiotensin-converting enzymes. Using both linear (GA-LDA) and non-linear (RF) algorithms, mt-QSAR classification models were developed using 983 chemicals to predict inhibitory effects on Neprilysin and Angiotensin-converting enzymes. The Box-Jenkins method, feature selection method, and machine learning algorithms were employed to obtain the most predictive model with ~ 90% overall accuracy. Additionally, the study employed virtual screening of designed scaffolds (Chalcone and its analogues, 1,3-Thiazole, 1,3,4-Thiadiazole) applying developed mt-QSAR models and molecular docking. The identified virtual hits underwent successive filtration steps, incorporating assessments of drug-likeness, ADMET profiles, and synthetic accessibility tools. Finally, Molecular dynamic simulations were then used to identify and rank the most favourable compounds. The data acquired from this study may provide crucial direction for the identification of new multi-targeted cardiovascular inhibitors.
心血管疾病包括心力衰竭、中风和高血压,影响全球 6.08 亿人,导致 32%的死亡。60%的患者需要联合治疗,包括同时抑制肾素-血管紧张素-醛固酮系统(RAAS)和 Neprilysin。本研究介绍了一种新的多靶点计算机模拟技术(mt-QSAR),用于评估对 Neprilysin 和血管紧张素转换酶的抑制潜力。使用线性(GA-LDA)和非线性(RF)算法,使用 983 种化学物质开发了 mt-QSAR 分类模型,以预测对 Neprilysin 和血管紧张素转换酶的抑制作用。采用 Box-Jenkins 方法、特征选择方法和机器学习算法,获得了具有约 90%整体准确性的最具预测性模型。此外,该研究还采用开发的 mt-QSAR 模型和分子对接对设计的支架(查尔酮及其类似物、1,3-噻唑、1,3,4-噻二唑)进行虚拟筛选。鉴定的虚拟命中物经历了连续的过滤步骤,包括评估药物相似性、ADMET 概况和合成可及性工具。最后,使用分子动力学模拟来识别和排名最有利的化合物。本研究获得的数据可为鉴定新的多靶点心血管抑制剂提供重要方向。
