Description: DS-1558 is a potent and orally available GPR40 agonist.DS-1558 was found to have potent glucose lowering effects during an oral glucose tolerance test in ZDF rats. DS-1558 significantly and dose-dependently improved hyperglycemia and increased insulin secretion during the oral glucose tolerance test in Zucker fatty rats, the model of insulin resistance and glucose intolerance. DS-1558 not only increased the glucose-stimulated insulin secretion by GLP-1 but also potentiated the maximum insulinogenic effects of GLP-1 after an intravenous glucose injection in normal Sprague Dawley rats.
