PF-04620110
PF-04620110 is a potent, selective and orally-bioavailable inhibitor of diacylglycerol acyltransferase 1 (DGAT-1), an enzyme catalyzing the final committed step in the biosynthesis of triglycerides, that inhibits DGAT-1 with values of 50% inhibition concentration IC50 of 19 nM and 8 nM in human and HT-29 cells respectively. PF-04620110 displays a highly selective, more than 100 fold, inhibition against DGAT-1 rather than a range of lipid processing enzymes, including human DGAT-2, human acyl-CoA:cholesterol acyltransferase 1, human acyl-CoA:wax alcohol acyltransferase 1, human acyl-CoA:wax alcohol acyltransferase 2, human acyl-CoA:monacylglycerol acyltransferase 2, human acyl-CoA:monacylglycerol acyltransferase 3 and mouse MGAT 1.

In Vitro Assay for DGAT-1 Enzyme Inhibition: |
Human full-length diacylglycerol:acylCoA acyltransferase 1 (DGAT-1) was expressed in Sf9 insect cells which are then lysed and a crude membrane fraction (105, 000 x g pellet) was prepared. DGAT-1 activity was measured in 384-well format in a total assay volume of 25 μl that contained, Hepes buffer (50 mM, pH7.5), MgCl2 (10 mM), bovine serum albumin (0.6 mg/ml), [14C]decanoylCoA (20 μM, 58 Ci/mol) and membranes (25 μg/ml) into which 1,2 dioleoyl-sn-glycerol (75 μM) in acetone has already been incorporated. Inhibitors in DMSO were pre-incubated with membranes before initiating the DGAT-1 reaction by the addition of decanoylCoA.The reactions were allowed to proceed for 1.5 h at room temperature and then terminated by the addition of 10 μl of HCl (0.5 M). Reaction mixtures were neutralized by the addition of 15 μl of tris(hydroxy-methyl)aminomethane (1M, pH 8.0) and then mixed by trituration with 37.5 μl of Microscint-E . Plates contents were allowed to partition for 15 to 30 min before 14C was measured in a scintillation spectrometer. Percent inhibition of test compounds was computed as 100-(DPM DMSO uninhibited- DPM test compound)/(DPM DMSO uninhibited). |

|
Applications |
PF-04620110 (IC50 39 nM) inhibits the incorporation of 3H-glycerol into TG. |
| Animal experiment [2]: | |
|
Animal models |
C57BL/6J and B6.129S4-Dgat1tm1Far (DGAT1 knockout mice) male mice (7–12 wk of age) |
|
Dosage form |
Oral dose of 1, 0.3, 0.1, and 0.01 mg/kg (TG/retinyl palmitate tolerance test) |
|
Applications |
Administration of a single dose of a DGAT1 inhibitor, PF-04620110, reduces postprandial plasma TG and retinyl palmitate excursions in mice. |
|
Other notes |
Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal. |
