    Description

    GW-1100 is a selective GPR40 antagonist with a pIC50 of 6.9.

    IC50 & Target

    pIC50: 6.9 (GPR40)[1]
    In Vitro

    GW-1100 (GW1100) dose dependently inhibits GPR40-mediated Ca2+ elevations 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 produces a significant rightward shift in the concentration-response curve to GW9508 (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 concentrations of GW-1100 of 3 μM and higher a significant decrease in the maximal response is observed with a continuing rightward shift in the pEC50 response[2]. GW-1100 (GW1100) reduces FFAR1 ligand-induced intracellular calcium in CHO-K1/bFFAR1 cells and neutrophils. CHO-K1/bFFAR1 cells are incubated for 15 min with 10 μM GW1100 or vehicle (0.1% DMSO) and then stimulated with vehicle, oleic acid, linoleic acid or GW9508. GW-1100 significantly reduces the increase in intracellular calcium induced 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].

    In Vivo

    The intracerebroventricular injection of DHA (50 μg) and GW9508 (1.0 μg), a GPR40-selective agonist, significantly reduces mechanical allodynia and thermal hyperalgesia at day 7, but not at day 1, after CFA injection. These effects are inhibited by intracerebroventricular pretreatment with GW-1100 (10 μg), a GPR40 antagonist[4].

    In Vivo:

    Select the appropriate dissolution method based on your experimental animal and administration route.

    For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
    To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for in vivo experiments, it is recommended to prepare freshly and use it on the same day.
    The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

    • Protocol 1

      Add each solvent one by one:  10% DMSO    40% PEG300    50% PBS

      Solubility: 5 mg/mL (9.60 mM); Suspended solution; Need ultrasonic

    • Protocol 2

      Add each solvent one by one:  10% DMSO    90% Corn Oil

      Solubility: ≥ 2.5 mg/mL (4.80 mM); Clear solution

      This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown). If the continuous dosing period exceeds half a month, please choose this protocol carefully.

      Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL Corn oil, and mix evenly.

    Cell Assay
    [3]

    CHO-K1/bFFAR1 or CHO-K1/pcDNA3.1 cells (2×106 cells/2 mL) are loaded with 2.5 μM Fura-2AM fluorescent indicator dye in recording buffer (10 mM HEPES, 140 mM NaCl, 2 mM CaCl2, 21 mM MgCl2, 25 mM KCl, 10 mM glucose, pH 7.4) for 30 min, washed three times with recording buffer, and returned to the incubator for 10 min. Cells are incubated with different concentrations of 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) or vehicle (0.1% DMSO). The fatty acid concentrations used in all experiments are in the range of concentrations of healthy and peripartum cows. In another set of experiments, cells are incubated with either 10 μM GW-1100 for 15 min, 2 μM U73122 for 3 min or vehicle (0.1% DMSO) for 15 min and then stimulated with either 300 μM oleic acid, 100 μM linoleic acid or 10 μM GW9508. Cellular fluorescence (Ca2+) is measured at 509 nm emission with 340/380 nm dual wavelength excitation using a LS55 spectrofluorimeter. Cuvette temperatures are maintained at 37°C with constant stirring[3].

    Animal Administration
    [4]

    Mice[4]
    Male ddY mice (age, 4 weeks) are housed in cages at 23-24°C with a 12-h light-dark cycle (lights from 8 am to 8 pm) and food and waterad libitum. DHA (50 µg/mouse), the selective GPR40-agonist GW9508 (1.0-25 µg/mouse) and the GPR40 antagonist GW1100 (1-10 µg/mouse) are dissolved in 1% DMSO and the solution is diluted with saline before von Frey testing (1% DMSO final concentration). The doses of GW9508 are chosen based upon our previous publication, whereas GW-1100 is selected on the basis of previous reports and our preliminary experiments. Under a non-anesthetized state, DHA and GW9508 are administered via the intracerebroventricular (i.c.v.) route 10 min before CFA injection, and GW1100 is administered via the i.c.v. route 10 min before GW9508 injection. Flavopiridol (5 and 15 nmol/mouse), a cyclin-dependent kinase inhibitor, is administered by i.c.v. injection into the left lateral ventricle of the mice twice a day (at 9:00 and 19:00) after CFA treatment.

    Help & FAQs
    • Do most proteins show cross-species activity?

      Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
