  Synthesis and evaluation of pyridazinone–phenethylamine derivatives as selective and orally bioavailable histamine H3 receptor antagonists with robust wake-promoting activity

  摘要：

  A series of pyridazinone-phenethylamine derivatives with moderate to low nanomolar affinity for rat and human H3R are described. These analogs exhibited excellent selectivity and metabolic stability, with acceptable rat pharmacokinetic properties. In vivo, 7 and 11 demonstrated potent H3R functional antagonism in the rat dipsogenia model and robust wake-promoting activity in the rat electroencephalogram/electromyography (EEG/EMG) model.
