  • Cyclic amine derivative and pharmaceutical use thereof
    Patent number: 9505740
    Abstract: A compound exerts a strong analgesic effect against pain, in particular, neuropathic pain and/or fibromyalgia syndrome. The cyclic amine derivative is represented by formula, a prodrug thereof or a pharmacologically acceptable salt thereof: wherein A represents a group represented by Formula (IIa), (IIb) or (IIc): wherein R3 represents a hydrogen atom or an alkyl group having 1 to 6 carbon atoms, R4 represents a hydrogen atom or an alkylcarbonyl group having 2 to 6 carbon atoms or an alkyl group having 1 to 6 carbon atoms and optionally substituted with an alkylcarbonylamino group having 2 to 6 carbon atoms and n represents 1 or 2, in which when R3 and R4 each independently represent an alkyl group having 1 to 6 carbon atoms, R1 represents an alkyl group having 1 to 6 carbon atoms and substituted with a hydroxyl group, an amino group or a carboxyl group.
