Researchers aimed to discover natural compounds with anti-COVID-19 properties by testing phytochemicals from a traditional medicine plant against the main proteases of the SARS-CoV-2 virus, which play a key role in replication and transcription. They used computer tools to identify the most promising compounds, and identified betulin, coclaurine, and quinic acid from the plant as showing significant binding affinity to the SARS-CoV-2 main proteases. These compounds could potentially serve as leads for developing specific anti-COVID-19 treatments.
Researchers investigated the potential use of plant compounds for treating COVID-19 using molecular docking experiments. The compounds showed high binding affinity and two were further explored. Molecular mechanics-based calculations were used to re-rank the candidates, with two compounds being confirmed as stable in association with viral protease. The compounds' geometries, electrical properties, chemical reactivity, and intermolecular interactions were also studied. These in silico discoveries have identified potential COVID-19 inhibitors and could contribute to antiviral drug discovery.
Scientists have conducted a study on AQCH tablets as a potential treatment for dengue and COVID-19 infections. The study aimed to evaluate the safety and pharmacokinetics of AQCH in healthy human subjects. AQCH has shown to have anti-viral activity in in vitro and small animal studies. With no effective vaccine or drug available for dengue, this study brings hope for a potential treatment option. The results of this study suggest that AQCH tablets are safe and well-tolerated in humans, and could be a promising solution in the fight against dengue and COVID-19.
Researchers evaluated the effectiveness and safety of purified aqueous extract of Cocculus hirsutus (AQCH) combined with standard care in hospitalized patients with moderate COVID-19. AQCH has shown strong antiviral activity in laboratory studies. There is a critical need for a safe and effective oral therapy for COVID-19.
