The papain-like protease (PLPro) is a highly conserved, non-structural protein that plays a crucial role in the formation of the replication-transcription complex and the processing of polyproteins in SARS-CoV-2, as well as improving the host’s antiviral immune responses against said virus. Chalcone is a common ingredient, which can be found in a multitude of natural substances, such as food and herbs. It has been proven to have various biological activities, including antiviral effects. Previous studies have identified several natural chalcone-based compounds with the ability to inhibit SARS-CoV-2 by targeting the PLPro enzyme. Based on these findings, this study investigated potential chalcone-derived PLPro inhibitors, as retrieved from Pubchem and in-house libraries. Virtual screening protocols, specifically molecular docking and molecular dynamics simulating filter, were applied to reach the desired goal. As a result, 1448 out of 1454 chalcone derivatives can effectively bind to SARS-CoV-2 via PLPro. The 5 substances with the most suitable docking score and binding mode were selected for the next step. Through MD, CID1021201513 and CID101585417 showed the greatest potential in targeting PLPro. However, further in vitro and in vivo studies must be conducted before the bio-activities of these chalcones against SARS-CoV-2 can be confirmed. Furthermore, the ligand-protein interaction mode analysed in this research can help design effective chalcone derivatives.

The main purpose of this study is to examine the impact of credit risk management on profitability of commercial banks in Vietnam. While the existing literature emphasizes the necessity for a more in-depth study and additional empirical evidence to elucidate intricate relationships between market dynamics and credit risk, particularly in the context of commercial banks in Southeast Asia, there remains a gap in comprehensive studies, with a specific focus on Vietnam. The secondary data was collected from 20 commercial banks from the country for the period of 11 years, from 2012 to 2022. The study used non-performing loans ratio (NPLR), capital adequacy ratio (CAR) as well as loan-loss provision ratio (LLPR) as proxies of credit risk while the financial performance is measured by return on equity (ROE). Moreover, the bank's characteristics, such as its size (SIZE), the macroeconomic inflation rate (INF), and a dummy variable that looks at how ownership type (OWN) affects the bank's profitability are all applied to quantify the independent variables. The model does not exhibit the multicollinearity issue, according to the mean Variance Inflation Factor (VIF) data. The regression results reveal that SIZE, CAR and INF variables have a significant positive effect on ROE, while the NPLR variable has an opposite significant effect on ROE. Nevertheless, there is no connection between the ROE-measured financial performance of commercial banks and the OWN or LLPR variables. This offers further valuable insights to bankers and policy makers in credit risk management of commercial banks in Vietnam to enhance the stability of the Vietnamese banking system.
