BU 226 hydrochloride is a selective ligand of imidazoline2 receptor [1].
Imidazoline receptor is the primary receptor for clonidine and other imidazolines. Imidazoline2 receptor (I2 receptor) is an allosteric binding site of monoamine oxidase and plays an important role in neuroprotection and pain modulation.
BU 226 hydrochloride is a selective ligand of I2 receptor. BU226 exhibited high affinity for I2 receptor with Ki value of 1.4 nM and displayed 380-fold selectivity against I1 receptor. Also, BU226 showed low affinity for α2-adrenoceptor. In rat brain or kidney membranes, BU226 showed affinity for I1, I2 receptors and α2-adrenoceptor with IC50 value of 534.5 nM and Ki values of 2.7 and 6700 nM, respectively [1]. In pig brain, BU226 displaced of 2BFI with Ki value of 44.7 nM, which suggested the presence of imidazoline I2 binding site [2].
In male Hooded Lister rats, BU226(1.6-7.0 mg/kg) potently substituted for 2-BFI with ED50 value of 3.2 mg/kg in a dose-dependent way [3].
