結果を以下に示す。
(1)膀胱排尿筋の収縮作用の測定
<摘出標本の作製>
ラットをペントバルビタールで麻酔し、腹部を切開して、膀胱および尿道を摘出した。膀胱は体部を縦方向に切断し、約10×3 mmの短冊状の標本を作製した。また、尿道についても約10×3 mmの標本を作製した。作製した標本は、95%O2、5%CO2混合ガスで通気したクレブス緩衝液(37℃、5 mL)中に懸垂した。標本の張力は、等尺性トランスデューサーおよびアンプを装備したマグヌス装置システムを用い、データ収集システムを介してコンピューター上に記録した。
<膀胱に対する作用測定>
標本を約0.5 gの負荷で懸垂し、1時間以上経過した後、塩化カリウム(100 mmol/L)を添加し、最大収縮反応を観察した。クレブス緩衝液で洗浄後、標本を約0.5gの負荷で懸垂し、安定化させた。その後に、塩化カリウム溶液(7.5 mmol/L)を添加し、収縮を惹起した。惹起反応が安定した後に、被験化合物を累積添加し、薬物処置前後の反応を測定した。塩化カリウム溶液添加による惹起収縮(mg)を100%とした時の被験化合物の各濃度における張力変化率(%)を算出した。
<結果>
結果を以下に示す。
製剤例1
化合物18の結晶形C(5.0 g)、カルボキシメチルセルロース カルシウム(20 g)、ステアリン酸マグネシウム(10 g)および微結晶セルロース(920 g)を常法により混合したのち、打錠して、1錠中に0.5 mgの活性成分を含有する錠剤1万錠を得た。
製剤例2
化合物18の結晶形A(2.0 g)、マンニット(500 g)および蒸留水(10 L)を常法により混合したのち、溶液を常法により滅菌し、1 mLずつバイアルに充填し、常法により凍結乾燥し、1バイアル中0.2 mgの活性成分を含有するバイアル1万本を得た。
また、本発明化合物は、膀胱排尿筋の収縮および尿道括約筋の弛緩作用を有するので、膀胱収縮障害および/または尿道弛緩障害を改善し、低活動膀胱予防および/または治療剤として有効である。また、低活動膀胱における種々の症状の改善剤としても有効である。そこで、安定な結晶である本発明化合物を原薬として用い、長期投与するための経口剤を製造すれば、非常に有効な低活動膀胱治療剤となり得る。
