Biological Activity
GSK334429 is a potent, selective histamine H3 receptor (H3R) antagonist with pKi of 9.49 and 9.12 for human and rat H3 receptors respectively.
GSK334429 is a potent functional antagonist (pA(2)= 8.84) versus H(3) agonist-induced changes in cAMP) and exhibits inverse agonist properties (pIC50=8.59 versus basal GTPgammaS binding).
GSK334429 potently inhibited cortical ex vivo [(3)H]-R-alpha-methylhistamine binding (ED(50)=0.35 mg/kg).
GSK334429 (3 and 10 mg/kg p.o.) significantly reversed amnesia induced by the cholinergic antagonist scopolamine in a passive avoidance paradigm.
