A new and more aggressive strain of coronavirus, known as SARS-CoV-2, which is highly contagious, has rapidly spread across the planet within a short period of time. Due to its high transmission rate and the significant time-space between infection and manifestation of symptoms, the WHO recently declared this a pandemic. Because of the exponentially growing number of new cases of both infections and deaths, development of new therapeutic options to help fight this pandemic is urgently needed. The target molecules of this study were the nitro derivatives of quinoline and quinoline N-oxide. Computational design at the DFT level, docking studies, and molecular dynamics methods as a well-reasoned strategy will aid in elucidating the fundamental physicochemical properties and molecular functions of a diversity of compounds, directly accelerating the process of discovering new drugs. In this study, we discovered isomers based on the nitro derivatives of quinoline and quinoline N-oxide, which are biologically active compounds and may be low-cost alternatives for the treatment of infections induced by SARS-CoV-2.
一种新型且更具侵略性的冠状病毒,称为 SARS-CoV-2,其具有很强的传染性,在短时间内迅速在全球范围内传播。由于其高传播率以及从感染到出现症状之间的显著时空间隔,世界卫生组织(WHO)最近宣布这是一种大流行。由于感染和死亡的新病例数量呈指数级增长,因此迫切需要开发新的治疗方法来帮助对抗这种大流行。本研究的靶分子是喹啉和喹啉 N-氧化物的硝基衍生物。在 DFT 水平上进行计算设计、对接研究和分子动力学方法作为合理的策略,将有助于阐明各种化合物的基本物理化学性质和分子功能,直接加速新药发现的过程。在这项研究中,我们发现了基于喹啉和喹啉 N-氧化物的硝基衍生物的异构体,这些化合物是具有生物活性的化合物,可能是治疗由 SARS-CoV-2 引起的感染的低成本替代品。
