(Test method)
Transfection The PPAR activation effect of the test compound was measured as follows. Receptor expression plasmid (pSG5-GAL4-hPPARα or γ or δ LBD), luciferase expression plasmid (pUC8-MH100 × 4-TK-Luc) and β-galactosidase (ATCC (American type culture collection)) pCMX-β-GAL) expression plasmid (Kliewer, SA et al., (1992) Nature, 358: 771-774) was introduced. After gene transfer using the transfection reagent Lipofectamine 2000 (Invitrogen), the cells were cultured in the presence of the test compound for 40 hours. Solubilized cells were used for measuring luciferase activity and β-GAL activity. Luciferase activity was corrected with β-GAL activity, and the luciferase activity value of cells treated with GW-590735 (PPARα selective agonist), Rosiglitazole (PPARγ selective agonist), GW-501516 (PPARδ selective agonist) was taken as 100%. , Relative ligand activity was calculated.
