Abstract:Corona Virus Disease 2019 (COVID-19) broke out in 2019 and spread rapidly around the world. There is still no specific antiviral therapy to the current pandemic. In China, historical records show that Traditional Chinese Medicine (TCM) is effective in prevention and enhancing the resistance to pandemic with unique insights. To fight with COVID-19, National Health and Commission of PRC has recommended some TCM in the guideline, such as HuoxiangZhengqi, LianhuaQingwen ShufengJiedu and XueBijing, and actually dis… Show more
“…The previous study explained that this antioxidant might increase T-cell subsets, lymphocyte reactions to mitogen, interleukin-2 production, potentiated natural killer cell activity, and in uenza virus response compared with placebo. The use of antioxidants in the therapy process is essential to maintain physical and spiritual conditions during the quarantine period, and the healing process is quickly completed 31,32 .…”
BACKGROUND : SARS-Cov-2 causes an coronavirus disease 2019 (COVID-19), and the vaccines or drugs of this disease have not been found to inhibit this replication of the virus. Researchers are engaged in all fields of study to discover new potential inhibitors. This study aimed to compute the binding energy (BE) and interactions between the new potential inhibitors and the SARS-Cov-2 Mainprotease (Mpro).METHODS: In this study, we docked between twenty-seven patented drugs and the Mpro receptor (PDB ID: 6W63). The molecular docking calculation was performed using AutoDock Tools 1.5.6. software. Moreover, the information about the biological activity of ligands was calculated using the PASS online server. The result of the calculation was then analyzed and visualized using Biovia Discovery Studio Visualizer. Further calculation, such as the ligand-protein interaction using STITCH database and Lipinski’s rule five were employed in this research.RESULTS: The molecular docking calculation results showed that nelfinavir was strongly bound to Mpro with BE of -9,51 kcal/mol, followed by lopinavir, vitamin D, ritonavir, and dexamethasone. From these ligands, we considered dexamethasone because this ligand works as an anti-inflammatory agent. CONCLUSIONS: Following the calculation, nelfinavir, lopinavir, and dexamethasone are proposed as a potential inhibitor of the Mpro receptor, but there is a need for further investigation.

“…Traditional Chinese medicines (TCM) are widely used in China and some Chinese communities outside China, with characteristics of low cost, good curative effect, short duration of treatment, and multiple targets. Numerous facts prove that it is feasible to treat human and animal diseases with TCM, which can effectively relieve symptoms, reduce the development from mild to moderate or severe, improve the cure rate, reduce mortality rate, and promote the recovery of patient by means of "multi-component, multi-target, multi-pathway" (Cantwell, 2010;Huang et al, 2020;Luo et al, 2020;Tong et al, 2020;Yuan et al, 2016).…”
The Coronavirus Disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has rapidly become a global pandemic. Up to now, numerous medicines have been applied or approved for the prevention and control of the virus infection. However, the efficiency of each medicine or combination is completely different or still unknown. In this review, we discuss the types, characteristics, antiviral mechanisms, and shortcomings of recommended candidate medicines for SARS-CoV-2 infection, as well as perspectives of the drugs for the disease treatment, which may provide a theoretical basis for drug screening and application.
“…In addition to the above mentioned, Lianhua Qingwen can regulate the imbalance of ACE-Ang-II and ACE2-Ang-(1-7), which can lead to overwhelming pro-inflammatory cytokines with cytokine storm. And regulating immune-related signal pathway (MAPK, NF-κB, PI3K-AKT, ect) to protect organ damage [ 145 ]. Fig.…”

Scutellaria baicalensis Georgi. (SB) is a common heat-clearing medicine in traditional Chinese medicine (TCM). It has been used for thousands of years in China and its neighboring countries. Clinically, it is mostly used to treat diseases such as cold and cough. SB has different harvesting periods and processed products for different clinical symptoms. Botanical researches proved that SB included in the Chinese Pharmacopoeia (1st, 2020) was consistent with the medicinal SB described in ancient books. Modern phytochemical analysis had found that SB contains hundreds of active ingredients, of which flavonoids are its major components. These chemical components are the material basis for SB to exert pharmacological effects. Pharmacological studies had shown that SB has a wide range of pharmacological activities such as antiinflammatory, antibacterial, antiviral, anticancer, liver protection, etc. The active ingredients of SB were mostly distributed in liver and kidney, and couldn't be absorbed into brain via oral absorption. SB’s toxicity was mostly manifested in liver fibrosis and allergic reactions, mainly caused by baicalin. The non-medicinal application prospects of SB were broad, such as antibacterial plastics, UV-resistant silk, animal feed, etc. In response to the Coronavirus Disease In 2019 (COVID-19), based on the network pharmacology research, SB’s active ingredients may have potential therapeutic effects, such as baicalin and baicalein. Therefore, the exact therapeutic effects are still need to be determined in clinical trials. SB has been reviewed in the past 2 years, but the content of these articles were not comprehensive and accurate. In view of the above, we made a comprehensive overview of the research progress of SB, and expect to provide ideas for the follow-up study of SB.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
