Stannsoporfin ( SnMP), also known as Tin mesoporphyrin, is a porphyrin-Sn(IV) complex, is also a potent heme oxygenase inhibitor, that inhibits HO-1–mediated heme catabolism with potential medicinal application for the treatment of both neonatal jaundice and inherited hyperbilirubinemia syndromes. It was developed to possess unique structural and photophysical properties that make it a particularly potent and bioavailable in vivo inhibitor suitable for clinical use in newborns and studies to date have revealed a very favorable therapeutic profile with no significant adverse side effects.
