COVID-19 Chemicals

Antiviral agents and compound libraries for COVID-19 research

To date, treatment of patients with severe COVID-19 is limited, since potential therapies are still in the trial phases. Researchers look for antiviral drugs, inhibiting infection or replication of the coronavirus, as well as immunomodulatory compounds. The latter is relevant because many patients experience an overwhelming and sometimes deadly production of proinflammatory cytokines, known as the cytokine storm. Bio-Connect offers several compounds that can potentially alter the immune response in COVID-19 patients, such as Tocilizumab, which is a monoclonal antibody blocking the IL-6 receptor. We also offer promising agents relevant to antiviral research, such as Remdesivir (GS-5734), Camostat mesylate (TMPRSS2) and Favipiravir (T-705). These compounds are investigated for their interference with SARS-CoV-2 and closely related viruses in the human body. On this page, you will also find compounds that are more distantly related to infectious diseases and have the potential to be effective in SARS-CoV-2 infection. Many of these compounds have already been approved for treatment of other diseases and therefore provide a strong advantage over new compounds, which would have to go through thorough safety testing. Finally, we offer an Anti-COVID-19 Compound Library (HY-L052) from MedChemExpress. If you want to order, please send your request to: orders(at)bio-connect.nl
