Abstract

Coronavirus disease 2019 (COVID-19) is an emerging infectious disease caused by Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2). This virus infects the respiratory, digestive, and nervous systems with a rapid transmission and a fairly high mortality rate. However, there has been no specific therapy to treat COVID-19. Previous studies have shown that antisense oligonucleotide (ASO) has good efficacy in DNA and RNA viral infections. This literature review aims to investigate the potential of inhaled ASO based on gold nanoparticles (AuNp) delivery system in inhibiting the replication and transcription of SARS-CoV-2. Literature searching using several databases, such as Google Scholar, Science Direct, ResearchGate, and NCBI. Inclusion and exclusion criteria are used to eliminate the journals that does not match the criteria, thus 28 journals are obtained. The results show that ASO has the potential to inhibit the replication and transcription of the SARS-CoV-2 virus through different mechanisms by binding to the target RNA and modulating the viral protein synthesis. One form of ASO modification that is often used is LNA GapmeR. LNA GapmeR stimulates viral RNA cleavage and can be administered by inhalation with nebulized ASO solution. AuNP as an ASO delivery system through inhalation can reduce toxicity and increase ASO concentrations in reaching target cells. Therefore, ASO therapy with AuNP through inhalation needs to be considered for COVID-19 treatment. Further clinical study about the ideal delivery system and optimal dosage of ASO based AuNP via inhalation for COVID-19 are needed to investigate soon.

Abstract

COVID-19 pandemic caused by SARS-CoV-2 is a challenge for researchers to find effective drugs for this disease. Previous research had identified the role of Mpro, TMPRSS2, RdRp, and ACE2 which were useful as promising drug targets to inhibit SARS-CoV-2. This study aims to identify the potential compounds derived from Ginkgo biloba as potential SARS-CoV-2 inhibitors using a molecular docking study. A total of twenty-one compounds of Ginkgo biloba and comparative drugs were used in this study. The materials were downloaded from rcsb for protein targets and pubchem for comparative drugs and compounds. In this study, Lipinski rule of five using Swiss ADME web tool was used. Moreover, toxicity analysis using admetSAR 2.0 online test also used to predict toxicological profile of compounds. Dockings were carried out on Mpro, TMPRSS2, RdRp, and ACE2 protein targets by AutodockTools 1.5.6 and Autodock Vina. The visualization of molecular interaction was carried out by Discovery Studio v16. Nine compounds met the criteria as drug-like components and were safe. Docking results showed that ginkgolide-C and bilobetin showed strong molecular interactions to all protein targets compared to the comparative drugs and other compounds. In RdRp, ginkgolide-C showed the highest binding energy with -12.7 kcal/mol. Moreover, in TMPRSS2, ACE2 and Mpro, bilobetin also showed the highest binding energy with -12.7, -9.7 and -10 kcal/mol, respectively. Ginkgolide-C and bilobetin have the potential to be developed as SARS-CoV-2 inhibitors. Therefore, in vitro and in vivo investigations are needed to bring these compounds to the clinical setting.
