  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.

  6-4-[3-(R)-2-Methylpyrrolidin-1-yl) propoxy]-phenyl}-2H-pyridazin-3-one 6 (Irdabisant; CEP-26401) was recently reported as a potent H3R antagonist with excellent drug-like properties and in vivo activity that advanced into clinical evaluation. A series of pyridone analogs of 6 was synthesized and evaluated as H3R antagonists. Structure-activity relationships revealed that the 5-pyridone regiomer was optimal for H3R affinity. N-Methyl 9b showed excellent H3R affinity, acceptable pharmacokinetics and pharmaceutical properties. In vivo evaluation of 9b showed potent activity in the rat dipsogenia model and robust wake-promoting activity in the rat EEG model. (C) 2011 Elsevier Ltd. All rights reserved.
