Researchers have developed a new compound that can prevent long COVID symptoms in mice that could lead to a future drug for the debilitating condition in humans. Developed by researchers at the Walter and Eliza Hall Institute of Medical Research (WEHI) in Melbourne, the world-first study found mice treated with the antiviral compound were protected from long-term brain and lung dysfunction, which are key symptoms of long COVID.
Yeda Research and Development Co. Ltd. has divulged broad-spectrum coronavirus entry inhibitors reported to be useful for the treatment of SARS-CoV-2 infection (COVID-19), SARS-CoV infection and Middle East respiratory syndrome coronavirus (MERS-CoV) infection.

Work at Vir Biotechnology Inc. has led to the identification of 3C-like proteinase (3CLpro; Mpro; nsp5) (SARS-CoV-2; COVID-19 virus) inhibitors reported to be useful for the treatment of SARS-CoV-2 infections (COVID-19).

Multisystem inflammatory syndrome in children (MIS-C), a serious disorder that develops after SARS-CoV-2 infection, could arise from latent infection of another pathogen, the Epstein-Barr virus (EBV). Researchers at Charité – Universitätsmedizin Berlin and the German Rheumatology Research Center (DRFZ) have linked the inflammatory effect of this co-infection with transforming growth factor β (TGF-β), ruling out the possibility that MIS-C is caused by an autoimmune reaction, or persistence of the coronavirus in the body.
Although several vaccines and drugs are available against SARS-CoV-2, the search for effective therapeutic agents for COVID-19 and future zoonotic coronaviruses continues. The RNA-dependent RNA polymerase (RdRp) is a relevant drug target in several RNA viral infections, such as SARS-CoV-2 (targeted by the approved drugs remdesivir and molnupiravir), hepatitis C, influenza and dengue viruses.
Although safe and effective vaccines for SARS-CoV-2 have been successfully developed, there are currently no therapeutic approaches available for treating acute infection, particularly for individuals at high risk of severe disease progression, and for preparedness against a potential new coronavirus pandemic.
