Based on 3 publication(s) in Google Scholar
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.

Protocolo
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.
