PROBLEM TO BE SOLVED: To provide a cation channel inhibitor usable for suppression/regulation of sensation or reduction in nervous sensation or unpleasant sensation sensed in daily life.SOLUTION: A cation channel inhibitor includes a compound represented by formula (1) as an active ingredient. In the formula: R1 is a hydrocarbon group which may have a substituent, or a hydrogen atom R2-R6 are the same or different mutually and are each a hydrogen atom, a halogen atom, or a hydrocarbon group which may have a substituent optionally selected two of R2-R6 may form a ring and R2-R6 are not simultaneously hydrogen atoms when R1 is a hydrogen atom or a methyl group.COPYRIGHT: (C)2013,JPO&INPIT【課題】感覚の抑制又は調整、あるいは日常感じる過敏な感覚又は不快な感覚の低減に利用することができる、カチオンチャネル阻害剤の提供。【解決手段】下記式(1)(式中、R1は置換基を有していてもよい炭化水素基又は水素原子を表し、R2~R6はそれぞれ同一又は異なって、水素原子、ハロゲン原子、又は置換基を有していてもよい炭化水素基を表す。R2~R6は、これらの中から選ばれる任意の2つで環を形成してもよい。但し、R1が水素原子又はメチル基の場合、R2~R6がすべて水素原子であるものを除く。)で示される化合物を有効成分とすることを特徴とするカチオンチャネル阻害剤。【選択図】なし
