API FG-4592 Roxadustat Hair Growth Peptide CAS 808118-40-3 FG4592

FG-4592 (also known as ASP1517), 2-(4-hydroxy-1-methyl-7-phenoxyisoquinoline-3-carboxamido)acetic acid,

is a potent small molecule inhibitor of hypoxia-inducible factor prolyl hydroxylase (HIF-PH),
an enzyme up-regulating the expression of endogenous human erythropoietin (Epo).
It is currently being investigated as an oral treatment for anemia associated with chronic kidney disease (CKD).

Unlike other anemia treating agents, erythropoiesis-stimulating agents (ESAs),

FG-4592 inhibits HIF, through a distinctive mechanism, by stabilization of HIF. According to previous studies,

FG-4592 is capable of correcting and maintaining hemoglobin levels in CKD patients not
receiving dialysis and in patients of end-stage renal disease

who receives dialysis but do not need intravenous iron supplement.
