We identified (5'S)-10'-fluoro-6'-methyl-5',6'-dihydro-3'H-spiro[cyclopropane-1,4'-[2,6]diaza[2,5]methano [2,6]benzodiazonin]-7'(1'H)-one, 22b (DS34942424) with a unique and original bicyclic skeleton. 22b showed an orally potent analgesic in the acetic acid-induced writhing test and formalin test in ddY mice without sedation. Moreover, 22b did not exhibit mu opioid receptor agonist activity.
