- Assay description: Measurement of Human MGAT2 Inhibitory Activity: A full-length human MGAT2 gene to which a Flag-tag had been added at the N-terminal was inserted into pFastBac (from Invitrogen). A recombinant baculovirus was produced in accordance with the protocol for a Bac-to-Bac baculovirus expression system (produced by Invitrogen), and Sf-9 cells were infected therewith. The cells were collected and sonicated, and then the membrane fraction was collected through centrifugation. Western blotting analysis with an anti-Flag antibody was performed for the membrane fraction to confirm expression, and the membrane fraction was used as a recombinant human MGAT2 enzyme solution. Solutions of the compounds of the present invention in DMSO were each aliquoted into 0.2-μL portions in a 384-well polystyrene microplate produced by Corning Incorporated, and 5 μL of an enzyme solution prepared with an assay buffer (100 mmol/L phosphate buffer (pH 7.4) containing 2 mmol/L DTT) and 5 μL of a substrate solution (100 mmol/L phosphate buffer (pH 7.4), 30 μmol/L 2-Oleoylglycerol, 10 μmol/L Oleoyl-CoA) were added thereto, and the resultant was stirred and centrifuged, and incubated in a moist chamber at room temperature for 1 hour. After enzymatic reaction, 50 μL of a quenching solution (containing 0.2 μmol/L Diolein-d5, 0.4% formic acid, and 50% isopropanol) containing Internal Standard (IS) was added to terminate the reaction, and the resultant was sealed in a plate produced by Shimadzu GLC Ltd., and then stirred and centrifuged, and measurement was performed by using an electrospray ionization method with a RapidFire360 and Agilent 6550 Q-TOF mass spectrometer. Diolein as a reaction product (P) of 2-Oleoylglycerol as the substrate and an ammonium adduct ion of the IS were detected, and the peak intensity ratio, P/IS, was calculated from the peak heights to evaluate the inhibitory activity. Inhibitory activities with/without addition of enzyme were defined as Control (+)/Control (−), respectively, and the respective % inhibitions were defined as 0% inhibition and 100% inhibition. The inhibitory activity was calculated from the formula below with TIBCO Spotfire (produced by TIBCO Software Inc.):Inhibitory activity (%)=[1−{Sample−Control(−)}/{Control(+)−Control(−))}]*100where Sample indicates a peak intensity ratio: P/IS, when the compound of the present invention was added.
