Review Description

The COVID-19 pandemic caused by SARS-Cov-2 demands rapid, safe and effective therapeutic options. In the last decades, the endogenous gasotransmitter hydrogen sulfide (HS) has emerged as modulator of several biological functions and its deficiency has been associated with different disorders. Therefore, many HS-releasing agents have been developed as potential therapeutic tools for diseases related with impaired HS production and/or activity. Some of these compounds are in advanced clinical trials. Presently, the pivotal role of HS in modulating the inflammatory response and pro-inflammatory cytokine cascade is well recognized, and the usefulness of some HS-donors for the treatment of acute lung inflammation has been reported. Recent data is elucidating several mechanisms of action, which may account for antiviral effects of HS. Noteworthy, some preliminary clinical results suggest an inverse relationship between endogenous HS levels and severity of COVID-19. Therefore, repurposing of HS-releasing drugs may be a potential therapeutic opportunity for treatment of COVID-19.
