MK-8617 (C007B-231062)

InformationMK-8617 is an pan-inhibitor of Hypoxia-inducible factor prolyl hydroxylase 1−3 (HIF PHD1−3), inhibiting PHD1 , 2 , 3 with IC50s of 1.0, 1.0 and 14 nM, respectively.TargetsPHD1 (Cell-free assay); PHD2 (Cell-free assay); PHD3 (Cell-free assay) 1 nM; 1 nM; 14 nMIn vitroMK-8617 is not a significant inhibitor of the cytochrome p450 enzymes in vitro (IC50), CYP1A2, 3A4, 2B6, 2C9, 2C19, or 2D6, >60 μM, and is a moderate reversible inhibitor of CYP2C8 at 1.6 μM in vitro. MK-8617 is inactive when screened at 10 μM against a general panel of 171 radioligand binding and enzymatic assays.In vivoTritiated MK-8617 exhibits minimal metabolic turnover in liver microsomes (+NADPH) from rat, dog, and monkey (<10% turover) but significant turnover in human liver microsomes (34% turnover) after 60 min (10 μM compound, 1 mg/mL microsomal protein). In terms of its pharmacokinetic profile, MK-8617 shows good oral bioavailability across species (36−71%), with low clearance and volume of distribution. The compound still has a relatively long elimination half-life across preclinical species. In mice (C57Bl/6), single doses of 5 and 15 mpk po (n = 3) causes increases in circulating reticulocytes measured on both 3 and 4 days postcompound challenge. In rat (Sprague−Dawley), a single dose titration of 1.5, 5, and 15 mpk po (n = 5) causes a large increase in serum erythropoietin(EPO) levels of 1.7-, 8-, and 204-fold relative to vehicle, respectively. Increases in circulating reticulocytes are observed at 5 and 15 mg/kg 3 days after challenge and, with the 15 mg dose, at 4 days after challenge.
