Histamine H3 receptor inverse agonists are known to enhance the activity of histaminergic neurons in brain and thereby promote vigilance and cognition. 1-{3-[3-(4-Chlorophenyl)propoxy]propyl}piperidine, hydrochloride (BF2.649) is a novel, potent, and selective nonimidazole inverse agonist at the recombinant human H3 receptor. On the stimulation of guanosine(More)
BF2.649, a high affinity and selective non-imidazole histamine H(3)-receptor antagonist/inverse agonist, was found to easily enter the brain after oral administration to mice: it displayed a ratio of brain/plasma levels of about 25 when considering either C(max) or AUC values. At low oral doses (2.5-20mg/kg), it elicited in mice a dose-dependent wakening(More)
