GW-1100 is a novel, potent and selective GPR40 antagonist with a pIC50 of 6.9. GPR40 has been reported to be activated by long-chain fatty acids, such as docosahexaenoic acid (DHA). Unfortunately, there aren't many studies looking into GPR40's functional role in the brain.

| ln Vitro |
GW-1100 (GW1100) dose-inhibitively inhibits the Ca2+ rise mediated by GPR40 stimulated by GW9508 and linoleic acid (pIC50 values of 5.99±0.03 and 5.99±0.06, respectively). GW-1100 at a concentration of 1 μM increased GW9508's There was a significant right shift in the concentration-response curve (pEC50=7.17±0.08 in the absence and pEC50=6.79±0.09 in the presence of 1 μM GW-1100; P<0.05; n=3). At GW-1100 concentrations of 3 μM or higher, a significant decrease in the maximum response was observed and a sustained drift in the pEC50 response [2] was observed. GW-1100 (GW1100) reduces intracellular FFAR1 ligand induction in CHO-K1/bFFAR1 cells and neutrophils CHO-K1/bFFAR1 cells were treated with 10 μM GW1100 or vehicle (0.1% DMSO) for 15 min followed by vehicle , oleic acid, linoleic acid or GW9508 stimulation. GW-1100 was significantly reduced by 300 μM oleic acid (AUC) (60-150 s), p<0.05), 100 μM linoleic acid (AUC (60-150 s), p<0.05) and 10 μM GW9508 (AUC (60-150 s), p<0.05)[3].

| ln Vivo |
Intracerebroventricular injection of DHA (50 μg) and GW9508 (1.0 μg), a GPR40-selective hemostatic agent, significantly reduced mechanical allodynia and thermal hyperalgesia on day 7 after CFA injection, but not GW on day 1. Intraventricular quiescence with -1100 (10 μg), a GPR40 antagonist, inhibits these effects [4].

| Cell Assay |
CHO-K1/pcDNA3 or CHO-K1/bFFAR1.In a recording buffer (10 mM HEPES, 140 mM NaCl, 2 mM CaCl2, 21 mM MgCl2, 25 mM KCl, 10 mM glucose, pH 7.4), 1 cell (2×106 cells/2 mL) is loaded with 2.5 μM Fura-2AM fluorescent indicator dye and left for 30 minutes. The cells are then rinsed three times with the recording buffer and put back into the incubator for 10, minutes. Propionic acid (1, 10 and 30 mM), oleic acid (0-500 μM), linoleic acid (0-200 μM), GW9508 (0-100 μM), ionomycin (2 μM), thapsigargin (2 μM), and vehicle (0.1% DMSO) are all incubated with the cells. The fatty acid concentrations utilized in each experiment fall within the range of what healthy, peripartum cows would normally have. In an additional series of tests, after 15 minutes of incubation with either 10 μM GW-1100, 3 minutes with 2 μM U73122, or 15 minutes with vehicle (0.1% DMSO), cells are stimulated with 300 μM oleic acid, 100 μM linoleic acid, or 10 μM GW9508. With a 340/380 nm dual wavelength excitation, cellular fluorescence (Ca2+) is measured at 509 nm emission using an LS55 spectrofluorimeter. Cuvettes are stirred continuously to maintain a temperature of 37°C[3].

| Animal Protocol |
Mice: Male ddY mice, four weeks of age, are kept in cages at 23–24°C with a 12-hour light–dark cycle (lights on from 8 am to 8 pm), as well as unlimited access to food and drink. Before conducting the von Frey test (with a final concentration of 1% DMSO), the following substances are dissolved in 1% DMSO: DHA (50 µg/mouse), the selective GPR40-agonist GW9508 (1.0-25 µg/mouse), and the GPR40 antagonist GW1100 (1-10 µg/mouse). The dosages of GW9508 are determined by our earlier publication, while the selection of GW-1100 is based on our preliminary experiments and earlier reports. DHA and GW9508 are given intracerebroventricular (i.c.v.) 10 minutes prior to CFA injection, and GW1100 is given via the same route 10 minutes prior to GW9508 injection in a non-anesthetized state. After CFA treatment, mice receive intraperitoneal injections of flavopiridol (5 and 15 nmol/mouse), a cyclin-dependent kinase inhibitor, twice daily (at 9:00 and 19:00) into their left lateral ventricle.

*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.
