Fasiglifam (formerly known as TAK-875; TAK875) is a novel, long-acting, selective and orally bioavailable GPR40 agonist with anti-diabetic activity. It activates GPR40 with EC50 of 14 nM in human GPR40 expressing CHO cell line, and is 400-fold more potent than oleic acid. Takeda terminated the development activities for fasiglifam (TAK-875) as a treatment modality for type 2 diabetes due to concerns about liver safety. TAK-875 has a favorable pharmacokinetic profile which enables long-acting drug efficacy. TAK-875 exhibited potent agonistic activity and high binding affinity to the human GPR40 receptor. In addition, TAK-875 showed excellent agonist potency and selectivity for GPR40 receptor over other members of the FFA receptor family (e.g. EC50>10 μM for others).
| ln Vitro |
In CHO-hGPR40, fasiglifam (TAK-875) (0.01-10 μM) increases intracellular IP synthesis in a concentration-dependent manner with an EC50 of 0.072 μM. In CHO cells, facilifam (TAK-875) (0.1–10 μM) dose-dependently increases intracellular IP production[1]. [Ca2+]i increases concentration-dependently with facoldifam (TAK-875) (3-30 μM). TAK-875 (0.001-10 μM) dose-dependently increases insulin production from INS-1 833/15 cells in the presence of 10 mM glucose[2].

| ln Vivo |
In ZDF rats, fasiglifam (TAK-875) (10 mg/kg, po) raises plasma insulin levels. Without changing fasting normoglycemia, facsiglifam (TAK-875) (30 mg/kg, po) reduces hyperglycemia while fasting. doses that increase glucose tolerance in diabetic rats by three to ten times are found to be at 30 mg/kg, which has no effect on fasting glucose levels in SD rats with normal glucose homeostasis. In SD rats with normal fasting glucose levels, Fasiglifam (TAK-875) does not significantly change insulin secretion [1].

| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.5 mg/mL (4.77 mM) (saturation unknown) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution. Solubility in Formulation 2: ≥ 2.5 mg/mL (4.77 mM) (saturation unknown) in 10% DMSO + 90% (20% SBE-β-CD in Saline) (add these co-solvents sequentially from left to right, and one by one), clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 900 μL of 20% SBE-β-CD physiological saline solution and mix evenly. Preparation of 20% SBE-β-CD in Saline (4°C，1 week): Dissolve 2 g SBE-β-CD in 10 mL saline to obtain a clear solution. View More

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
