Substituted phenoxypropyl-(R)-2-methylpyrrolidine aminomethyl ketones as histamine-3 receptor inverse agonists
Optimization of a series of aminomethyl ketone diamine H3R antagonists to reduce the brain exposure by lowering the pKa, led to molecules with improved pharmacokinetic properties. Compounds 9, 19, and 25 had high affinity for human H3R and demonstrated in vivo H3R functional activity in the rat dipsogenia model. Compound 9 displayed modest wake-promoting activity in the rat EEG/EMG model.
