Biological Activity
Adrenergic receptor[1]
The formation of high-affinity Guanoxabenz binding seems to be inhibited by a series of N-hydroxyguanidine analogs to Guanoxabenz, as well as by a series of metabolic inhibitors that included allopurinol, 1-chloro-2,4-dinitrobenzene, 5,59-dithiobis-(2-nitrobenzoic acid), cibacron blue, phenyl-p-benzoquinone, didox, and trimidox. The formation of Guanoxabenz high-affinity binding is also inhibited in a time- and concentration-dependent fashion by preincubating the membranes with the LW03 N-hydroxyguanidine analogue of Guanoxabenz[1]. The spleen cytosolic fraction mediates the reduction of Guanoxabenz to guanabenz, the latter having an almost 100-fold higher affinity for rat alpha2A-adrenoceptors than Guanoxabenz itself[2].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
Guanoxabenz (0.1-3 mg/kg, i.p.) causes a dose-related reduction in locomotor activity; a dose of 1 mg/kg is selected since this induces a pronounced and sustained behavioural hypoactivity[4].

Animal Model:Rats[4].
-
Dosage:0.5 mg/kg (RX 781094 or saline vehicle was injected intravenously (tail vein) at the time of peak effect of the agonist (20min for clonidine and 30 min for Guanoxabenz).
-
Administration:IP.
-
Result:RX 781094 (0.1-1.0 mg/kg, i.v.) produces a rapid (< 5 set) and complete antagonism of the EEG and behavioural effects induced by clonidine and Guanoxabenz.
