ただし、X31が単結合であり、R31が置換基を有していてもよい複素環式アミノ基である場合は、当該単結合は当該複素環式アミノ基の窒素原子以外の原子と結合している(この規定は、−X31−R31が、後述するような「R33およびR34はそれらが単結合であるX33およびX34を介して結合している窒素原子と共に一体となって置換基を有していてもよい複素環式アミノ基を表す」場合の−N(−X33−R33)(−X34−R34)と重複することを避けるためのものである)。
海馬硬化症モデルマウスの作製と測定 (図1〜図3):海馬硬化症モデルマウスの作製は、過去の文献に従って行った (非特許文献15)。6-7週令のICRマウスを実験に用いた。マウスをケタミン (100 mg/kg) とキシラジン (20 mg/kg) 混合液によって十分に麻酔をかけた後、脳定位固定装置にセットした。頭部の海馬上方から微小ガラス電極とハミルトンシリンジを用いて、てんかん誘発のために微量のカイニン酸 (0.8 nmol, 40 nL) を背側海馬(ブレグマの後方に 1.6 mm, 中心線から側方に 1.6 mm, 脳表面から深さ 1.4 mm)に注入し、次にてんかん脳波記録のための金属電極(200 μm径)をカイニン酸注入部位付近に埋め込んだ。さらに、in vivo 電気測定に必要な頭部固定のために、小型のプラスチック製U字枠も頭部に取り付けた。手術から2週間以上経過後、海馬におけるてんかん波を測定した。頭部は、U字枠を介して固定し、てんかん波は増幅され、バンドパスフィルター (0.5-30 Hz) を介して測定し、ADコンバータを用いてコンピュータに取り込んだ。ベースライン脳波を30分間測定後、スチリペントール (300 mg/kg)、イソサフロール (100-300 mg/kg)、オキサミド酸ナトリウム (250-500 mg/kg)、もしくは生理食塩水を腹腔内投与し、1時間記録した。オキサミド酸ナトリウムは水に溶かし、スチリペントールとイソサフロールはカルボキシルメチルセルロースナトリウム (1%) に溶かして腹腔内投与した。データ解析において、0.5 mV 以上の振幅を持つ高振幅のてんかん波を投与前30分間と投与後30分間でそれぞれカウントし、投与前のてんかん波の数で規格化することにより薬効を評価した。海馬硬化症による形態変化の観察では、脳を 300 μmでスライスした後、10% ホルマリンで固定し、0.05% のクレシルバイオレットで染色した。
海馬硬化症を伴う内側側頭葉てんかんは、成人の代表的な難治性てんかん (既存の薬が効かないてんかん) である。まず、過去の文献 (非特許文献15) に従い、微量のカイニン酸を海馬に投与し、海馬硬化症モデルマウスを作製した (図1A)。カイニン酸投与から2週間以上経つと、海馬では形態的変化が観察され、ピラミダル神経細胞層は細くなり (図1B; CA1)、歯状回領域は肥大化した (図1B; DG)。これは、既に報告されている海馬硬化症モデルマウスと同じ所見であり (非特許文献15)、ヒト海馬硬化症で見られる症状に類似している (非特許文献16)。また、その海馬から記録を行うと、自発的に生じる高振幅のてんかん波が観察された (図1C; 矢尻)。すなわち、この海馬硬化症モデルマウスは、従来研究での報告通り慢性てんかんモデルである。
