S-methylisothiourea

S-methylisothiourea is a small molecule compound primarily used as a chemical intermediate in the synthesis of guanidine derivatives and various pharmaceuticals. It acts as an inhibitor of inducible nitric oxide synthase (iNOS), thereby reducing the production of nitric oxide in biological systems. This mechanism has made it useful in research settings for studying inflammatory processes and related pathologies. In industry, it serves as an intermediate for synthesizing fungicides (such as dimethomorph), insecticides (such as pyrimidinoxyphos), and pharmaceutical agents including guanethidine salts and hydrocortisone sodium phosphate[8][1]. It is not approved or marketed as a therapeutic drug but is widely used in chemical synthesis.
