DC260126 is a potent antagonist of GPR40 (FFAR1). DC260126 dose-dependently inhibits GPR40-mediated Ca2+ elevations stimulated by linoleic acid, oleic acid, palmitoleic acid and lauric acid (IC50: 6.28, 5.96, 7.07, 4.58 μM, respectively). DC260126 could protect MIN6 β cells from palmitate-induced ER stress and apoptosis.

Description

DC260126 is a potent antagonist of GPR40 (FFAR1). DC260126 dose-dependently inhibits GPR40-mediated Ca2+ elevations stimulated by linoleic acid, oleic acid, palmitoleic acid and lauric acid (IC50: 6.28, 5.96, 7.07, 4.58 μM, respectively)[1]. DC260126 could protect MIN6 β cells from palmitate-induced ER stress and apoptosis[2].

In Vitro

DC260126 reduces GTP-loading and ERK1/2 phosphorylation stimulated by linoleic acid in GPR40-CHO cells, suppresses palmitic acid potentiated glucose-stimulated insulin secretion, and negatively regulates GPR40 mRNA expression induced by oleic acid in Min6 cells[1].

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    5% Tween-80    45% Saline

    Solubility: ≥ 2.5 mg/mL (8.13 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.

    Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
  • Protocol 2

    Add each solvent one by one:  10% DMSO    90% (20% SBE-β-CD in Saline)

    Solubility: ≥ 2.5 mg/mL (8.13 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.

    Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.

Mice[1]
Male C57BL/KsJ-Lepdb (db/db) are maintained in a 12 h light-dark cycle at a temperature of 23°C with free access to water and regular chow diet. To investigate the dose-dependent effect of DC260126, nine-week-old db/db male mice are divided into four groups (n=6/group). Mice are give vehicle (5% DMSO in PBS) or DC260126 (3, 10, 30 mg/kg) once daily by tail vein injection for 5 days. At day 5, each group of mice are fasted for 6 h and blood samples are collected from orbital venous plexus and centrifuged for serum separation. Then the concentration of serum insulin level is measured by ELISA kit. For long term experiments, six-week-old obese db/db male mice are divided into two groups (n=8/group) and given vehicle (5% DMSO in PBS) or DC260126 (10 mg/kg) once daily by tail vein injection for 24 days, respectively.
Rats[2]
Female obese (fa/fa) Zucker rats are maintained in a 12:12 light-dark cycle with free access to water and a high-fat diet containing 15% fat, 1% cholesterol, 0.5% sodium cholate and 15% sucrose, except when fasted before some experiments. Rats at 8 weeks of age are divided into two groups (n=6/group) on the basis of body weight. Rats are injected intraperitoneally once daily with vehicle (propylene glycol) or DC260126 (6 mg/kg) for 8 weeks. Food intake and body weight are monitored periodically. At the end of the experimental period, mice are fasted for 12 h and then blood is collected. Liver, renal, adipose tissues are rapidly excised and weighed. Liver samples are snap frozen in liquid nitrogen and stored at -80°C for western blotting analysis.

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.
