    TAK-875 increases (p<0.05) the membrane expression of FFAR1 compared to the untreated control by 97%.

    Fasiglifam purchased from MedChemExpress. Usage Cited in: J Cell Biochem. 2017 May;118(5):1249-1261.  [Abstract]

    Free fatty acid receptor 1 (FFAR1) agonist induces LOX-1 upregulation in cultured vascular smooth muscle cells (VSMCs). Cultured VSMCs are treated with synthetic agonists for either FFAR1 (TAK-875) or FFAR4 (TUG-891) at indicated doses for 24 hours. Both FFAR1 and FFAR4 are known responsible for long chain fatty acids. 0.1% DMSO is used as solvent control (SC). Western blotting detection indicates that treatment with agonistic action of FFAR1, but not FFAR4, remarkably upregulated LOX-1 expressi

    Description

    Fasiglifam (TAK-875) is a potent, selective and orally bioavailable GPR40 agonist with EC50 of 72 nM.

    IC50 & Target

    EC50: 72 nM (GPR40)

    In Vitro

    Fasiglifam (TAK-875) (0.01-10 μM) produces a concentration-dependent increase in intracellular IP production in CHO-hGPR40, with EC50 of 0.072 μM. Fasiglifam (TAK-875) (0.1-10 μM) dose-dependently augments intracellular IP production in CHO cells[1]. Fasiglifam (TAK-875) (3-30 μM) concentration-dependently augments [Ca2+]i. In the presence of 10 mM glucose, TAK-875 (0.001-10 μM) dose-dependently stimulats insulin secretion from INS-1 833/15 cells[2].

    MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

    In Vivo

    Fasiglifam (TAK-875) (10 mg/kg, p.o.) increases plasma insulin levels in ZDF rats. Fasiglifam (TAK-875) (30 mg/kg, p.o.) improves fasting hyperglycemia without affecting fasting normoglycemia. Fasiglifam (TAK-875) at 30 mg/kg, which is a 3- to 10-fold higher dose compared with the dose that improved glucose tolerance in diabetic rats, does not alter fasting glucose levels in SD rats with normal glucose homeostasis. Likewise, Fasiglifam (TAK-875) does not significantly alter insulin secretion in SD rats with normal fasting glucose levels [1].

    In Vivo:

    Select the appropriate dissolution method based on your experimental animal and administration route.

    For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
    To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for in vivo experiments, it is recommended to prepare freshly and use it on the same day.
    The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

    • Protocol 1

      Add each solvent one by one:  10% DMSO    40% PEG300    5% Tween-80    45% Saline

      Solubility: ≥ 2.5 mg/mL (4.77 mM); Clear solution

      This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).

    Cell Assay
    [1]

    INS-1 832/13 cells are suspended in RPMI medium and seeded in a 96-well plate at a density of 2×104 cells/well; 1% BSA and 0.1% DMSO alone (control), palmitic acid (10, 100, and 1000 μM), oleic acid (10, 100, and 1000 μM), or Fasiglifam (TAK-875: 1, 10, and 100 μM) is added to the plate. After 72-h culture, medium is discarded, and cells are preincubated for 2 h with KRBH containing 1 mM glucose and 0.2% BSA at 37°C. After discarding of the preincubation buffer, KRBH containing 1 or 20 mM glucose and 0.2% BSA is added, and the plate is further incubated for 2 h. The insulin concentration in the supernatant is measured as described above. To measure intracellular insulin content, INS-1 832/13 cells are exposed to 1% BSA and 0.1% DMSO alone (control), palmitic acid (1000 μM), oleic acid (1000 μM), or Fasiglifam (TAK-875) (100 μM) with 1% BSA and 0.1% DMSO. After incubation, cells are washed once with phosphate-buffered saline, and acid-ethanol solution is added to each well, followed by sonication on ice. Intracellular insulin is extracted by overnight incubation at −30°C, followed by separation of supernatant by centrifugation at 12,000 rpm×5 min at 4°C.

    Animal Administration
    [1]

    At 18 weeks of age, the N-STZ-1.5 rats are fasted overnight and orally given vehicle (0.5% methylcellulose) or Fasiglifam (TAK-8751, 3, and 10 mg/kg). Sixty minutes later, all animals receive an oral glucose load (1 g/kg). Blood samples are collected from the tail vein before drug administration, before glucose load (time 0), and 10, 30, 60, and 120 min after the glucose load. Plasma glucose and insulin levels are measured with an AutoAnalyzer 7080 and radioimmunoassay, respectively. To see the effects of Fasiglifam (TAK-875) on fasting normoglycemia and hyperglycemia, SD rats (8 weeks old) or ZDF and ZL rats (12 weeks old) are fasted overnight and orally given vehicle (0.5% methylcellulose), Fasiglifam (TAK-875) (10 or 30 mg/kg), nateglinide (50 mg/kg), or glibenclamide (10 mg/kg). Blood samples are collected from the tail vein before drug administration (time 0) and 0.5, 1, 2, and 3 h (SD rats) and 0.5, 1, 2, 4, and 6 h (ZDF and ZL rats) after drug administration, and plasma glucose and insulin levels are measured as described above.

    • Do most proteins show cross-species activity?

      Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
