Optimization of the R2 and R6 positions of (5-4-[3-(R)-2-methylpyrrolin-1-yl-propoxy]phenyl}-2H-pyridazin-3-one) 2a with constrained phenoxypiperidines led to the identification of 5-[4-(cyclobutyl-piperidin-4-yloxy)-phenyl]-6-methyl-2H-pyridazin-3-one 8b as a potent, selectivehistamineH3receptor antagonist with favorable pharmacokinetic properties. Compound 8b had an excellent safety genotoxocity

pyridazin-3-one histamineH3receptor (H3R) antagonists/inverse agonists identified 6-4-[3-(R)-2-methylpyrrolidin-1-yl)propoxy]phenyl}-2H-pyridazin-3-one (8a, CEP-26401; irdabisant) as a lead candidate for potential use in the treatment of attentional and cognitive disorders. 8a had high affinity for both human (Ki = 2.0 nM) and rat (Ki = 7.2 nM) H3Rs with greater than 1000-fold selectivity over the hH1R

A novel series of 4-pyridazin-3-one and 5-pyridazin-3-one analogues were designed and synthesized as H3R antagonists. Structure-activity relationship revealed the 5-pyridazin-3-ones 8a and S-methyl 8b had excellent human and rat H3R affinities, and acceptable pharmacokinetic properties. In vivo evaluation of 8a showed potent activity in the rat dipsogenia model and robust wake-promoting activity in the rat EEG/EMG model. (C) 2012 Elsevier Ltd. All rights reserved.
