Abstract: The COVID-19 pandemic due to severe acute respiratory syndrome coronavirus
2 (SARS-COV-2) poses a major menace to economic and public health worldwide.
Angiotensin-converting enzyme 2 (ACE2) and transmembrane protease serine 2
(TMPRSS2) are two host proteins that play an essential function in the entry of SARS--
COV-2 into host cells. Hydrogen sulfide (H2S), a new gasotransmitter, has been shown to
protect the lungs from potential damage through its anti-inflammatory, antioxidant, antiviral,
and anti-aging effects. It is well known that H2S is crucial in controlling the inflammatory
reaction and the pro-inflammatory cytokine storm. Therefore, it has been suggested
that some H2S donors may help treat acute lung inflammation. Furthermore, recent research
illuminates a number of mechanisms of action that may explain the antiviral properties
of H2S. Some early clinical findings indicate a negative correlation between endogenous
H2S concentrations and COVID-19 intensity. Therefore, reusing H2S-releasing
drugs could represent a curative option for COVID-19 therapy.
