Imisopasem manganese

Imisopasem manganese (M40403) is a stable non-peptidyl mimetic of manganese superoxide MnSOD. In Vitro: Imisopasem manganese is a small molecule, synthetic manganese containing superoxide dismutase mimetic (SODm) that removes superoxide anions without interfering with other reactive species known to be involved in inflammatory responses (e.g. nitric oxide, NO and peroxynitrite, ONOO-)^[1]. In Vivo: Imisopasem manganese is a small-molecule superoxide dismutase mimetic that has shown efficacy in animal model disease states in which superoxide anions are thought to play a key role. Imisopasem manganese inhibits the inflammatory response following the intrapleural injection of carrageenan in rats. All parameters of inflammation are attenuated by Imisopasem manganese except for NOx, PGE2 and IL-10 which remains unaltered^[1]. Decreased apoptosis of the large and particularly the small bowel and marked recovery of both lymphoid and hematopoietic tissues occurs in the Imisopasem manganese pre-treated mice. Imisopasem manganese is effective in reducing TBI-induced tissue destruction and has potential as a new radioprotective agent^[2].
