CGP 12177 hydrochloride is a partial agonist of β3-adrenoceptor and an antagonist of β1- and β2-adrenoceptors with Ki values of 0.9, 4 and 88 nM for β1-, β2- and β3-adrenoceptors, respectively.
β3-adrenoceptor is exists mainly in adipose tissue and plays an important role in the regulation of thermogenesis and lipolysis.
CGP 12177 hydrochloride is a partial agonist of β3-adrenoceptor and an antagonist of β1- and β2-adrenoceptors. In human ventricular myocytes (HVMs), CGP12177 slightly activated L-type Ca2+ current (ICa,L) [1].
In sympathectomized (SX) interscapular brown adipose tissue (BAT) isolated from rats, CGP-12177 restored normal thyroxine (T4) deiodination, which suggested that CGP-12177 activated 5’-deiodinase type II through β3-adrenoceptor [2]. In spontaneously hypertensive rats (SHR) and normotensive rats, CGP12177 induced vasorelaxant effects and decreased hindquarters
perfusion pressure in a dose-dependent way induced by 5-hydroxytryptamine (5-HT), which was inhibited by bupranolol, a β1LA-adrenoceptor antagonist. These results suggested that CGP12177 induced vasorelaxant effects through activation of β1LA-adrenoceptor [3].
