TUG-770 (TUG770) is a novel, highly potent agonist of free fatty acid receptor 1 (FFA1/GPR40) with EC50 of 6 nM for hFFA1. TUG-770 possesses the ability to treat Type 2 Diabetes. GPR40, also known as free fatty acid receptor 1, is a new target for the treatment of type 2 diabetes because it increases the amount of insulin secreted from pancreatic β-cells in response to glucose stimulation.

| ln Vitro |
TUG-770 (Compound 22) displays excellent physicochemical and in vitro ADME properties, with good aqueous solubility, good chemical stability, low lipophilicity, and decreased plasma protein binding (PPB). In the Caco-2 cell assay, TUG-770 demonstrates good permeability and excellent stability toward human liver microsomes (HLM)[1]. TUG-770 demonstrates reduced potency when tested on the rodent orthologs (rFFA1, pEC50 = 6.49; mFFA1, pEC50 = 6.83)[1]. TUG-770 considerably boosts insulin secretion in the rat INS-1E cell line at high glucose concentrations (12.4 mM) (10.75% of total content with 10 μM 22 vs. 8.74 with vehicle) and has no effect at low glucose concentrations (2.8 mM) (4.14% of total content with 10 μM 22 vs. 4.02 with vehicle)[1]. |
| ln Vivo | TUG-770 (Compound 22; 20 mg/kg; oral administration; daily; for 28 days) treatment improves glucose tolerance significantly while having no effect on food intake, body weight, body composition, or plasma leptin concentration. The insulin sensitivity index (plasma glucose x plasma insulin) is likewise markedly enhanced by TUG-770 [1]. |
| Animal Protocol |
C56B1/6 male mice (5-6 weeks of age) fed on the 60% fat diet D12492 20 mg/kg Oral administration; daily; for 28 days |

Solubility Data
| Solubility (In Vitro) | DMSO: ≥ 100 mg/mL (~325.4 mM) |
| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.5 mg/mL (8.13 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 (8.13 mM) (saturation unknown) in 10% DMSO + 90% Corn Oil (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 corn oil and mix evenly.  (Please use freshly prepared in vivo formulations for optimal results.) |
