FG-4592 (ASP1517)
FG-4592 (ASP1517, Roxadustat; CAS 808118-40-3) is a small molecule inhibitor of hypoxia-inducible factor prolyl hydroxylase (HIF-PH), an enzyme responsible for regulating endogenous erythropoietin (EPO) expression. Inhibition of HIF-PH by FG-4592 results in stabilization and accumulation of hypoxia-inducible factor (HIF), thereby promoting EPO synthesis and stimulating erythropoiesis. Currently, clinical research is focusing on investigating orally administered FG-4592 as a treatment for anemia associated with chronic kidney disease (CKD), particularly in patients both dependent and independent of dialysis.
