化合物A.
運動性の測定のために準備したイヌに埋め込んだフォーストランスデューサーからの信号を処理して消化管運動性を評価した。すなわち、イヌをイソフルランで麻酔し、無菌条件下で腹腔を開腹した。フォーストランスデューサー(F−12IS、スターメディカル社、東京)を胃前庭部、胃体部、十二指腸、及び近位結腸の管腔外の漿膜側に縫着した。手術後、イヌに保護服を着せ、個別ケージに収容した。実験の前に一晩絶食したイヌを、遮蔽室に入れた。遠隔測定システム(GTS−800、スターメディカル社、東京)を用いて運動性を測定し、データ収集ソフトウェア(Eight Star、Star Medical、Tokyo)を備えたパーソナルコンピュータでデータを収集した。空腹期伝播性収縮(interdigestive migrating complex;IMC)を確認した後、試験薬を経口投与した。その後、5時間以上にわたって消化管運動を記録した。胃運動を定量的に評価するために、収縮面積を運動指数として算出した。フォーストランスデューサーからの信号をパーソナルコンピュータに収集し、処理ソフトウェア(Analyzer II;スターメディカル社)で分析した。空腹状態において、基準線と収縮曲線で囲まれた面積を投与後2時間ごとに測定した。標準化のために、算出した面積を投与前のIMCピーク高で割り、その結果を運動指数(MI)として用いた。結果は、平均値±標準誤差(S.E.M.、N=4−5)として示した。グラフパッドプリズム(GraphPad Software、グラフパッドプリズム社)を用いてダネットの多重比較試験法により統計学的分析を行った。
結果:
イヌにおいて、化合物Aは用量依存的(0.1〜10μg/kg)に胃前庭部運動を増加させた(図1)。化合物Aを経口投与した後の0〜2時間において、MIの変化は1μg/kgで統計学的に有意であったため、この値を本モデルにおける最低有効量とした。シサプリドは1mg/kgの用量で胃前庭部運動を顕著に増加させ(図2)、モサプリドは3mg/kgで前庭部運動を増加させる傾向があった(図3)。消化管運動実験におけるこれらのデータは、既に刊行された文献(Mikami T. et al.,J. Phrmacol. Exp. Ther.,325、190−199,2008;Mine Y. et al.,J. Phrmacol. Exp. Ther.,283、100−1008,1997)のデータと一致する。化合物Aは、胃前庭部運動の亢進の点で、シサプリドの約1000倍強い効能を示した。近位結腸においては、1μg/kgの化合物Aによって収縮の振幅及び頻度を増加させた(図4)。また、化合物Aは、投与後の伝播性大収縮の発生を促進した。一方、プルカロプリド(0.1mg/kg)を経口投与した結果、胃前庭部運動を亢進したが、この用量では近位結腸の収縮には全く影響を与えなかった。プルカロプリドは、高用量(0.3mg/kg)の治療においてのみ大腸運動を亢進させたが、この用量では過度の胃十二指腸収縮を誘発した(図5)。
機能性腸疾患の患者の多数が、消化管の上部および下部のいずれにも影響を及ぼす重複症状をしばしば呈している。例えば、過敏性腸症候群患者の多くは、胃食道逆流症も併発している。化合物Aは、最も高活性かつ高選択的な5−HT4作動物質の1つであり、同一用量で胃前庭部運動及び大腸運動を刺激する効果を発揮し、消化管における組職特異的活性はない。このような性質から、化合物Aは、上腹部不定愁訴または胸やけなどの上部消化管症状を伴う機能性便秘及び便秘型過敏性腸症候群の患者において、他の消化管運動促進剤の代わりとなる有用かつ実用性の高い代替剤であることが分かる。
プルカロプリドは最近、慢性便秘治療用として欧州医薬品庁から承認された。イヌを被験体とした本研究において、プルカロプリドは、近位結腸運動を亢進させる用量において過度な胃十二指腸収縮を誘発し、組職特異的活性が示唆される。一般的に、幽門輪や十二指腸の過度な収縮は、胃の内容物の排出には繋がらない。
