The vascular symptoms of hand-arm vibration syndrome, including cold-induced vasospasm, are in part mediated by increased sensitivity of cutaneous arteries to sympathetic stimulation. The goal of the present study was to use a rat tail model to analyze the effects...

alpha 2-Adrenergic receptor agonists are widely used in veterinary medicine as sedative/hypnotic agents. Four pharmacological subtypes of the alpha 2-adrenergic receptor (A, B, C and D) have been identified based primarily on differences in affinity for several drugs. The purpose...

Alpha-2 adrenergic receptors (alpha2 AR) mediate incorporation of guanosine 5'-O-(gamma-thio)triphosphate ([35S]GTPgammaS) into isolated membranes via receptor-catalyzed exchange of [35S]GTPgammaS for GDP. In the current study, we used [35S]GTPgammaS incorporation to characterize the intrinsic activity and potency of agonists and antagonists...

To evaluate in vivo brain penetration of α(2C)-adrenoceptor (α(2C)-AR) antagonists as a therapeutic agent, we synthesized two new (11)C-labeled selective α(2C)-AR antagonists 4-(6,7-dimethoxy-1,2,3,4-tetrahydroisoquinolin-2-yl)methyl-2-aryl-7-methoxybenzofuran ([(11)C]MBF) and acridin-9-yl-[4-(4-methylpiperazin-1-yl)phenyl]amine ([(11)C]JP-1302) as α(2C)-AR-selective positron emission tomography (PET) probes. The radiochemical yield, specific activity, and...
