The molecular docking calculations have been employed to investigate the interactions a set of proteins with the repurposed anti-COVID drugs. The position of the therapeutic agents within the protein structure was dependent on a particular drug-protein system and varied from the binding cleft to the periphery of the polypeptide chain. Interactions involved in the drug-protein complexation includes predominantly hydrogen bonding and hydrophobic contacts. The obtained results may be of particular importance while developing the anti-COVID strategies as well as for deeper understanding of the drug pharmacodynamics and pharmacokinetics.

Clinical studies have demonstrated that many traditional Chinese medicines (TCM) exhibit not only antiviral effects but also efficacy in alleviating clinical symptoms of Coronavirus Disease 2019 (COVID-19). However, the pharmacologically active constituents responsible for their anti-COVID-19 efficacy remain unclear. This study aimed to establish a novel strategy for identifying active ingredients from herbs clinically used for COVID-19.

Biopharmaceuticals such as peptides and antibodies have become critical to health care. Despite their exceptional potency and specificity, biopharmaceuticals are prone to aggregation, which can limit efficacy. These therapies therefore often require low-concentration formulations as well as cold storage to maintain stability; however, high doses are required to treat many diseases.

In pharmaceutical drug development, animal tests are traditionally required to conduct comprehensive toxicity assessments before initiating human clinical trials. However, animal tests are time-consuming and can hinder the rapid development of drugs needed to combat urgent health crises, such as the COVID-19 pandemic. Therefore, faster non-animal alternatives are critical to accelerating preclinical toxicity assessments.

Ethnopharmacological Relevance: Zhengqi Tablets (ZQP), derived from the "Huoxiang Zhengqi Powder" in the Song dynasty's "Taiping Huimin Ju Fang", have been endorsed by the Expert Consensus on Traditional Chinese Medcine Diagnosis and Treatment of New Coronavirus Infection in Shanghai (Spring Edition, 2022).
Aim Of The Study: The precise mechanisms underlying the efficacy of ZQP remain incompletely elucidated. To address this gap, we utilized a comprehensive approach integrating computer-aided virtual screening and biological validation to identify the active monomer within ZQP responsible for its anti-coronavirus properties.

Real-world data play a key role in monitoring drug safety at the post-marketing stage. However, challenges on how to rapidly and continuously obtain analytical results of many outcomes for drug safety signal monitoring still remain. We aimed to establish a rapid and continuous monitoring tool for drug safety assessment based on real-world data in Japan.
