Description

MK-8617 is an orally active pan-inhibitor of hypoxia-inducible factor prolyl hydroxylase 1-3 (HIF PHD1-3) with an IC50 of 1 nM for PHD2.

IC50 & Target

IC50: 1 nM (PHD2)[1]

In Vitro

MK-8617 is an orally active pan-inhibitor of hypoxia-inducible factor prolyl hydroxylase 1-3 (HIF PHD1-3) with an IC50 of 1 nM for PHD2. MK-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. The IC50 of MK-8617 is determined for factor inhibiting HIF (FIH) to be 18 μM[1].

In Vivo

Tritiated MK-8617 exhibits minimal metabolic turnover in liver microsomes from rat, dog, and monkey (<10% turover) but significant turnover in human liver microsomes (34% turnover) after 60 min (10 μM MK-8617, 1 mg/mL microsomal protein). In terms of its pharmacokinetic profile, MK-8617 shows good oral bioavailability across species (36 to 71%), with low clearance and volume of distribution. After 48 h treatment of MK-8617, postdose recovery of the radioactivity is about 26% bile, 12% urine, and 38% in feces, indicating that ~38% of the MK-8617 is absorbed and eliminated into bile and urine which is consistent with the oral bioavailability (~36%) observed in the rat study. MK-8617 also elicits an increase in erythropoietin (EPO) levels with a mouse MED of 1.5 mpk when dosed iv[1].

Kinase Assay
[1]

The catalytic activity assays for the HIF-PHD isoforms are performed at subsaturating levels of 2-oxoglutarate. To each well of a 96-well plate are added 1 μL of MK-8617 in DMSO and 20 μL of assay buffer containing 0.15 μg/mL FLAG-tagged full length HIF-PHD isoform expressed in and purified from baculovirus-infected Sf9 cells. After a 30 min preincubation at room temperature, the enzymatic reactions are initiated by the addition of 4 μL of substrates. After 2 h at room temperature, the reactions are terminated and signals are developed by the addition of a 25 μL quench/detection mix to a final concentration of 1 mM ortho-phenanthroline, 0.1 mM EDTA, 0.5 nM anti-(His)6 LANCE reagent, 100 nM AF647-labeled streptavidin, and 2 μg/mL (His)6-VHL complex. The ratio of time-resolved fluorescence signals at 665 and 620 nm is determined, and percent inhibition is calculated relative to an uninhibited control sample run in parallel[1].

Animal Administration
[1]

Male Sprague-Dawley rats (approximately 300 g each, n=15/arm) are dosed once daily for 28 days with vehicle (25:75 v/v PEG200/water+1 mol equiv of NaOH) or MK-8617 (1.5 or 15 mg/kg in vehicle). A group of age-matched, untreated controls (n=15) are included in the experiment. On study days 3, 14, and 28, blood samples (~0.25 mL) are obtained via jugular venipuncture and on study day 36 by cardiocentesis for hematological and MK-8617 level analyses[1].
