I1-imidazoline receptor activation by moxonidine has potent antigastric secretory and gastroprotective effects in rats. We therefore tested whether an imidazoline receptor antagonist, efaroxan, would influence gastric secretion and block the antisecretory and antiulcer effects of moxonidine. When given intracerebroventricularly (i.c.v.)

The properties of ATP-sensitive K+ (K(ATP)) channels were explored in the electrofusion-derived, glucose-responsive, insulin-secreting cell line BRIN-BD11 using patch-clamp techniques. In intact cells, K(ATP) channels were inhibited by glucose, the sulfonylurea tolbutamide, and the imidazoline compounds efaroxan and phentolamine. Each

An insufficient number of insulin-producing beta-cells is a major cause of defective control of blood glucose in both type 1 and type 2 diabetes. The aim of this study was to clarify whether the insulinotropic imidazolines can affect the survival

The potentiation of oxycodone antinociception by BMS182874 (endothelin-A (ET(A)) receptor antagonist) and agmatine (imidazoline receptor/α(2)-adrenoceptor agonist) is well-documented. It is also known that imidazoline receptors but not α(2)-adrenoceptors are involved in potentiation of oxycodone antinociception by agmatine and BMS182874 in

Agmatine, an endogenous ligand for imidazoline receptor, has been shown to prevent opioid dependence, but not much is known about the mechanisms of the effect of agmatine. In the present study, we investigated the function of I1 imidazoline receptor and
