The family of HIF-PH (HIF prolyl hydroxylase) enzymes are the main molecular to regulate HIF activity through hydroxylation at 2 proline residues and cause the degradation of HIF, thus leading to inhibition on accumulation of functional HIF under normoxia. FG-2216 is the PHD inhibitor with IC50 value of 3.9μM for PHD2 (measure by SAR study). Treatment with FG-2216 for 24h can stabilize HIF-1α and HIF-2α in Hep3B cells. Significant increase of EPO, as well as obvious band of HIF-1α and HIF-2α can be observed in Hep3B cells treated with 100μM FG-2216 for 24h[1]. Pre-treatment with FG-2216 at dose of 25 or 50mg/kg, b.w., i.p., 6h prior to initiation of ischaemia, caused HIF-1α and HIF-2α accumulation in kidney of rats, accompanied with increased transcriptional level of HIF targeted gene EPO and Glut-1[2]. FG-2216 increased hemoglobin in healthy volunteers and hemodialysis patients with CKD in a phase IIa study. Thus, it was regarded as the lead drug candidate for the treatment of CKD-related anaemia[3].
作用机制
FG-2216 can bind with the catalytically active domain of human PHD2 and fill the empty spaces with hydrophobic functional groups.[1]
