The hypoxia-inducible factor (HIF) pathway alters gene expression in response to low oxygen tension. Under normoxic conditions, HIF-specific prolyl hydroxylases (HIF-PHs) initiate the degradation of oxygen-sensitive HIF isoforms. As 2-oxoglutarate (2-OG) is a required co-factor for HIF-PH activity, analogs of 2-OG may inhibit HIF-PH and prevent HIF turnover. FG-4592 is an analog of 2-OG that has been developed as an inhibitor of HIF-PHs. While little has been published regarding the actions of this compound, similar HIF-PH inhibitors suppress HIF degradation and in this way induce erythropoietin expression, promoting erythropoiesis or preventing anemia in vivo.
