TAK-875_DataSheet_MedChemExpress
Inhibitors, Agonists, Screening Libraries Data SheetBIOLOGICAL ACTIVITY:TAK–875 is a potent, selective and orally bioavailable GPR40 agonist with EC 50 of 72 nM.IC50 & Target: EC50: 72 nM (GPR40)In Vitro: TAK–875 (0.01–10 μM) produces a concentration–dependent increase in intracellular IP production in CHO–hGPR40, with EC 50of 0.072 μM. TAK–875 (0.1–10 μM) dose–dependently augments intracellular IP production in CHO cells [1]. TAK–875 (3–30 μM)concentration–dependently augments [Ca 2+]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].In Vivo: TAK–875 (10 mg/kg, p.o.) increases plasma insulin levels in ZDF rats. TAK–875 (30 mg/kg, p.o.) improves fasting hyperglycemia without affecting fasting normoglycemia. 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,TAK–875 does not significantly alter insulin secretion in SD rats with normal fasting glucose levels [1].PROTOCOL (Extracted from published papers and Only for reference)Kinase Assay:[1]INS–1 832/13 cells are suspended in RPMI medium containing 11 mM glucose and the supplementsdescribed above. These cells are seeded at a density of 2×104 cells/well in a 96–well black plate coated with poly–D–lysine, and 1%BSA and 0.1% DMSO alone (control), palmitic acid (62.5, 125, 250, 500, and 1000 μM), oleic acid (62.5, 125, 250, 500, and 1000 μM), or TAK–875 (6.25, 12.5, 25, 50, and 100 μM) is added to the plate with 1% BSA and 0.1% DMSO, followed by culture for 72 h. After the culture, caspase 3/7 activity is measured with the Apo–one homogeneous caspase 3/7 assay according to the manufacturer's instructions. Fluorescence intensity is measured at an excitation of 485 nm and an emission at 535 nm.Cell Assay: TAK–875 is dissolved in 1% BSA and 0.1% DMSO. [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 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 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: TAK–875 is formulated in 0.5% methylcellulose.[1]At 18 weeks of age, the N–STZ–1.5 rats are fasted overnight and orally given vehicle (0.5% methylcellulose) or TAK–875 (1, 3, and 10 mg/kg). Sixty minutes later, all animals receive an oral glucoseProduct Name:TAK–875Cat. No.:HY-10480CAS No.:1000413-72-8Molecular Formula:C 29H 32O 7S Molecular Weight:524.63Target:GPR40Pathway:GPCR/G Protein Solubility:DMSO: ≥ 128 mg/mLload (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 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), 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.References:[1].
