    Thioglycine and l-thiovaline are stable under acidic and basic conditions but in the presence of bicarbonate they liberate the gasotransmitter H 2S. In cells both thioamino acids were proven to enhance cGMP formation and promote vasorelaxation in mouse aortic rings. Given that H 2S is known to lower arterial hypertension, reduce oxidative stress and exhibit cardioprotective effects in preclinical models, H 2S donors hold promise as novel treatments for cardiovascular diseases.
