    Product Description

    L-748,337 is a β3-adrenergic receptor antagonist that displays selectivity over β1 and β2 receptors (Kis = 4, 390, and 204 nM, respectively).1 It has been shown to couple with Gi to activate MAPK signaling.2 L-748,337 can inhibit agonist-stimulated lipolysis in rhesus monkey adipocytes, as well as agonist-induced relaxation of smooth muscle.1

    WARNING This product is not for human or veterinary use.
