Due to the bell-shaped/biphasic pharmacological character of H2S, pharmacological inhibitors of H2S biosynthesis (via the removal of the stimulatory effects of endogenously produced, CBS, CSE or 3-MST-derived H2S) as well as exogenous, pharmacological H2S donor compounds (via stimulation of multiple cytostatic and cytotoxic mechanisms) can exert anticancer effects.
