Dimethyloxaloylglycine

DMOG is an antagonist of α-ketoglutarate cofactor and inhibitor for HIF prolyl hydroxylase. (In Vitro) :DMOG efficiently suppresses hydroxyproline synthesis in intact cells, but shows only weakly active in the microsomal system. DMOG reduces FGF-2-induced proliferation and cyclin A expression by inhibiting prolyl hydroxylase activity in HPASMC. (In Vivo) :DMOG inhibits endogenous HIF inactivation, and induces angiogenesis in ischaemic skeletal muscles of mice. Up-regulation of hypoxia-inducible factor-1α by DMOG enhances the cardioprotective effects of ischemic postconditioning in hyperlipidemic rats.
