MK-8245 is a potent and liver-selective inhibitor of stearoyl-CoA desaturase (SCD) with IC50 value of 1nM [1].
SCD1 represents a therapeutic target for the treatment of type II diabetes, dyslipidemia, obesity, and metabolic diseases. As an inhibitor of SCD1, MK-8245 shows potency in both the rat enzyme and hepatocyte assay. There are no significant differences in potencies between the rat, mouse, and human SCD1. MK-8245 is developed as a liver-targeting SCD inhibitor. It demonstrates a liver-targeted tissue distribution profile resulting from a substrate recognition by organic anionic transporter proteins (OATPs) [1, 2].
MK-8245 is effective at lowering glucose level. It can improve glucose clearance dose-dependently with ED50 value of 7mg/kg. In the chronic eDIO mouse study, MK-8245 shows prevention of body weight gain with the maximally efficacious dose of 20 mg/kg bid based on body weight and liver triglyceride reduction [1].

SCD1 enzyme activity assay |
The potency of MK-8245 against the stearoyl-CoA desaturase was determined by measuring the conversion of radiolabeled stearoyl-CoA to oleoyl-CoA using rat liver microsome or human SCDl (hSCD-1). Liver microsome was prepared from male Wistar or Spraque Dawley rats on a high carbohydrate diet for 3 days. The livers were homogenized (1:10 w/v) in a buffer containing 250 mM sucrose, 1 mM EDTA, 5 mM DTT and 50 mM Tris-HCl (pH 7.5). After a 100,000 × g centrifugation for 60 mins, the liver microsome pellet was suspended in a buffer containing 100 mM sodium phosphate, 20% glycerol, 2 mM DTT and stored at -78 °C. The human SCDl desaturase system was reconstituted using human SCDl from a baculovirus/Sf9 expression system, cytochrome B5 and cytochrome B5 reductase. Typically, different concentrations of MK-8245 in 2 μL DMSO was incubated for 15 mins at room temperature with 180 μL of the SCD enzyme in a buffer containing 100 mM Tris-HCl (pH 7.5), ATP (5 mM), Coenzyme-A (0.1 mM), Triton X-100 (0.5 mM) and NADH (2 mM). The reaction was initiated by the addition of 20 μL of [3H]-stearoyl-CoA (final concentration = 2 μM, radioactivity concentration = 1 μCi/mL). After 10 mins, the reaction mixture (80 μL) was mixed with a calcium chloride/charcoal aqueous suspension (100 μL charcoal (10% w/v) plus 25 μL CaCl2 (2N)). After centrifugation to precipitate the radioactive fatty acid species, tritiated water released from 9,10-[3H]-stearoyl-CoA by the SCD enzyme was quantified on a scintillation counter. |
