Target: I1 imidazoline receptor, I2 imidazoline receptor
IC50: 35 nM, 47 nM
BU 239 hydrochloride is an imidazoline receptors-selective antagonist. BU239 displayed high affinity for both I1 imidazoline and I2 imidazoline receptors in competition binding experiments with IC50 values of 35 nM and 47 nM, respectively [1]. The imidazoline receptors involved in circulatory system are classified in two groups: the I1 type and the I2 type. I1 type is sensitive to idazoxan and clonidine, an antagonist with an imidazoline structure. I2 type displays a high affinity for idazoxan, cirazoline, guanabenz and a medium-tolow affinity for clonidine. In particular, Imidazoline I1 receptors play a critical role in the central regulation of blood pressure [2].
In vitro: BU239 (1 μM) reversed α2 agonists-mediated inhibition of arginine vasopressin (AVP)-stimulated water permeability in the rat inner medullary collecting duct (IMCD) [3]. In addition, BU239 significantly reversed agmatine-induced inhibition of AVP-stimulated urea permeability (Pu) in IMCD [4]. BU239 produced positive inotropic activity with the maximum effect observed at 117.4 % [2].
In vivo: N/A
