Abstract: Research in the last two decades has transformed the way hydrogen sulphide (H2S) is perceived from a noxious gas to a gaso-transmitter with a vast potential in pharmacotherapy. H2S is synthesized in various body-systems using the enzymes cystathionine beta-synthase and cystathionine gamma-lyase; either of these being the predominat enzyme in a particular system. H2S may be one of the physiological modulators of blood pressure in humans. The gas relaxes the vascular smooth muscle cells by opening up KATP channels. Moreover, it suppresses the proliferation of vascular smooth muscle cells. H2S may also be contributing in the protection afforded by ischaemia-preconditioning. Testosterone is thought to be responsible for the higher central nervous system level of H2S in males. In the central nervous system, H2S is implicated in Alzheimer’s disease, epilepsy, stroke and Down’s syndrome. Insulin secretion is associated with a decrease in the H2S levels. Raised H2S is detrimental in acute pancreatitis as well as in septic shock. Recently, H2S-releasing derivatives of certain drugs have shown promise in protection against gastric ulcer and in inflammatory bowel disease. The beneficial effects of certain sulphur containing herbs like ginseng and garlic may be mediated via H2S. In future, development of specific drugs modulating H2S levels may prove beneficial in varied disorders.
