Predicted therapeutic targets for COVID-19 disease by inhibiting SARS-CoV-2 and its related receptors.

ABSTRACT: The SARS-CoV-2 causes severe pulmonary infectious disease with an exponential spread-ability. In the present research, we have tried to look into the molecular cause of disease, dealing with the development and spread of the coronavirus disease 2019 (COVID-19). Therefore, different approaches have investigated against disease development and infection in this research; First, We identified hsa-miR-1307-3p out of 1872 pooled microRNAs, as the best miRNA, with the highest affinity to SARS-CoV-2 genome and its related cell signaling pathways. Second, the findings presented that this miRNA had a considerable role in PI3K/Act, endocytosis, and type 2 diabetes, moreover, it may play a critical role in the prevention of GRP78 production and the virus entering, proliferation and development. Third, nearly 1033 medicinal herbal compounds were collected and docked with ACE2, TMPRSS2, GRP78, and AT1R receptors, which were the most noticeable receptors in causing the COVID-19. Among them, there were three common compounds including berbamine, hypericin, and hesperidin, which were more effective and appropriate to prevent the COVID-19 infection. Also, it was revealed some of these chemical compounds which had a greater affinity for AT1R receptor inhibitors can be suitable therapeutic targets for inhibiting AT1R and preventing the adverse side effects of this receptor. According to the result, clinical assessment of these three herbal compounds and hsa-miR-1307-3p may have significant outcomes for the prevention, control, and treatment of COVID-19 infection.

Project description:Coronavirus belongs to the family of Coronaviridae, comprising single-stranded, positive-sense RNA genome (+ ssRNA) of around 26 to 32 kilobases, and has been known to cause infection to a myriad of mammalian hosts, such as humans, cats, bats, civets, dogs, and camels with varied consequences in terms of death and debilitation. Strikingly, novel coronavirus (2019-nCoV), later renamed as severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), and found to be the causative agent of coronavirus disease-19 (COVID-19), shows 88% of sequence identity with bat-SL-CoVZC45 and bat-SL-CoVZXC21, 79% with SARS-CoV and 50% with MERS-CoV, respectively. Despite key amino acid residual variability, there is an incredible structural similarity between the receptor binding domain (RBD) of spike protein (S) of SARS-CoV-2 and SARS-CoV. During infection, spike protein of SARS-CoV-2 compared to SARS-CoV displays 10-20 times greater affinity for its cognate host cell receptor, angiotensin-converting enzyme 2 (ACE2), leading proteolytic cleavage of S protein by transmembrane protease serine 2 (TMPRSS2). Following cellular entry, the ORF-1a and ORF-1ab, located downstream to 5' end of + ssRNA genome, undergo translation, thereby forming two large polyproteins, pp1a and pp1ab. These polyproteins, following protease-induced cleavage and molecular assembly, form functional viral RNA polymerase, also referred to as replicase. Thereafter, uninterrupted orchestrated replication-transcription molecular events lead to the synthesis of multiple nested sets of subgenomic mRNAs (sgRNAs), which are finally translated to several structural and accessory proteins participating in structure formation and various molecular functions of virus, respectively. These multiple structural proteins assemble and encapsulate genomic RNA (gRNA), resulting in numerous viral progenies, which eventually exit the host cell, and spread infection to rest of the body. In this review, we primarily focus on genomic organization, structural and non-structural protein components, and potential prospective molecular targets for development of therapeutic drugs, convalescent plasm therapy, and a myriad of potential vaccines to tackle SARS-CoV-2 infection.
