TGR5 Receptor Agonist is a novel, potent and synthetic small molecule agonist of TGR5 (G-protein coupled receptor19, GPCR19), it showed improved potency in the U2-OS cell assay with pEC50 of 6.8 and in melanophore cells with pEC50 of 7.5. TGR5 Receptor Agonist is a novel, potent small molecule agonist of the human TGR5 G-protein coupled receptor. It is described as a 3-aryl-4-isoxazolecarboxamide analog found through a high-throughput screening campaign. TGR5 Receptor Agonist demonstrated improved GLP-1 secretion in vivo via an intracolonic dose coadministered with glucose challenge in a canine model. Treatments for metabolic diseases like type II diabetes and its aftereffects may benefit from targeting G-protein coupled receptors.

| Enzyme Assay |
TGR5 Receptor Agonist was tested in over 100 internal and external 7TM, ion channel, enzyme, transporter, and nuclear hormone receptor selectivity assays, including FXR, another bile acid receptor. It only demonstrated a statistically significant response in the pro-inflammatory cytokine TNFalpha secretion (pIC50 = 6.8) in human primary monocytes after stimulation with lipopolysaccharide (LPS). TGR5 Receptor Agonist additionally exhibits favorable physicochemical characteristics and exhibits no detectable activity against hERG dofetilide binding (pIC50<4.3) or any of the three common cytochrome P450 (CYP450) isoforms, 1A2, 2C9, and 2D6.

| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 10 mg/mL (27.68 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 100.0 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: ≥ 10 mg/mL (27.68 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 100.0 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.) |

| 10 mM | 0.2768 mL | 1.3842 mL | 2.7684 mL |
*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.
Calculation results
Working concentration： mg/mL；
Method for preparing DMSO stock solution： mg drug pre-dissolved in μL DMSO (stock solution concentration mg/mL). Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug.
Method for preparing in vivo formulation:：Take μL DMSO stock solution, next add μL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O，mix and clarify.
(1) Please be sure that the solution is clear before the addition of next solvent. Dissolution methods like vortex, ultrasound or warming and heat may be used to aid dissolving.
(2) Be sure to add the solvent(s) in order.
