    Product Description

    Prazobind is an α1-adrenergic receptor (AR) antagonist.1 It inhibits binding of the α1-AR ligand, BE-2254, in rat hippocampus and liver, which highly express α1A- and α1B-ARs, respectively (IC50 = 1 nM for both).2 It decreases norepinephrine-induced contraction of isolated guinea pig aorta when used at a concentration of 1 nM.3

    WARNING This product is not for human or veterinary use.
