What is FG 2216?

Description

FG-2216 is an inhibitor of hypoxia-inducible factor prolyl hydroxylase 2 (HIF-PH2; IC₅₀ = 3.9 micromolar). It has been shown to reversibly stimulate erythropoietin secretion at 100 μM in vitro and to increase hematocrit, red blood cell count, and hemoglobin levels at 50 mg/kg in mice.

The Uses of FG 2216

FG 2216 is an erythropoietic agent which is orally active prolyl-hydroxylase inhibitor which increases erythropoietin production in end-stage kidney disease.

Biochem/physiol Actions

BIQ (FG-2216) is an orally available and potent inhibitor of prolyl-hydroxylase (PHD). BIQ induces significant and reversible plasma erythropoietin (EPO) levels in vitro and in hemodialysis patients.
