Molsidomine is an orally active, long acting vasodilating drug. Molsidomine is metabolized in the liver to the active metabolite linsidomine. Linsidomine is an unstable compound that releases nitric oxide (NO) upon decay as the actual vasodilating compound.

Molsidomine as well as linsidomine are sydnone imines, a class of mesoionic heterocyclic aromatic chemical compounds.

A mesoionic sydnone is active as an antianginal agent.

Its synthesis starts by reacting 1-aminomorpholine with formaldehyde and hydrogen cyanide to give 2. Nitrosation gives the N-nitroso analog (3) which cyclizes to the sydnone (4) on treatment with anhydrous acid. Formation of the ethyl urethane is then made possible by reacting Linsidomine with Ethyl chloroformate.
