【従来の技術】
尿道内圧低下作用を有する排尿困難治療剤として塩酸プラゾシン(塩酸1−(4−アミノ−6,7−ジメトキシ−2−キナゾリニル)−4−(2−フロイル)ピペラジン)が市販されているが、塩酸プラゾシンは同時に血圧低下作用も有するため、例えば、起立性低血圧を惹起するという副作用が報告されており、患者、特に老人には慎重な服用が要求される等の使用上の問題点が指摘されている。それ故、尿道内圧低下作用を主薬効とする排尿困難治療剤の有する副作用である血圧低下作用を軽減するため、選択的に尿道平滑筋の収縮を抑制し、強い血圧低下作用または起立性低血圧を惹起することのない新しいタイプの排尿困難治療剤の開発が強く嘱望されていた。

このようにして得られた前記一般式(II)の化合物は、ウサギの尿道を用いたin vitroの試験において、概ね5×10−11〜4×10−8Mの濃度で10−5Mのフェニレフリンによる収縮を50%抑制する活性を示した。例えば、(R)−1−ブチリル−5−〔2−〔2−〔2−(2,2,2−トリフルオロエトキシ)フェノキシ〕エチルアミノ〕プロピル〕インドリン−7−カルボキサミドは3.1×10−9Mの濃度で50%抑制活性を示した。また、北田真一郎らの試験(J.Smooth Muscle Res.,27(4),254(1991))に準拠した方法で実施した、ラットを用いたin vivoの試験において、前記一般式(II)の化合物は概ね0.5〜60μg/kgの用量でフェニレフリン(30μg/kg)により生じる尿道内圧の上昇を50%阻害する活性を示した。例えば、(R)−1−ブチリル−5−〔2−〔2−〔2−(2,2,2−トリフルオロエトキシ)フェノキシ〕エチルアミノ〕プロピル〕インドリン−7−カルボキサミドは1.3μg/kgで、(R)−1−(3−ヒドロキシプロピル)−5−〔2−〔2−〔2−(2,2,2−トリフルオロエトキシ)フェノキシ〕エチルアミノ〕プロピル〕インドリン−7−カルボキサミドは1.3μg/kgで50%阻害活性を示した。同様にして、現在排尿困難症の治療に使用されている塩酸プラゾシンについて試験を行った結果、4.0μg/kgで同様の効果が確認された。
【0052】
また、被検化合物を大腿静脈から静脈内投与したラットにおける通常行われるin vivoでの血圧測定試験において、塩酸プラゾシンが2μg/kg程度で10%血圧降下作用を示したのに対し、前記一般式(II)の化合物は約10〜100μg/kgで10%血圧降下作用を示した。例えば、(R)−1−ブチリル−5−〔2−〔2−〔2−(2,2,2−トリフルオロエトキシ)フェノキシ〕エチルアミノ〕プロピル〕インドリン−7−カルボキサミドは34μg/kg程度で、また(R)−1−(3−ヒドロキシプロピル)−5−〔2−〔2−〔2−(2,2,2−トリフルオロエトキシ)フェノキシ〕エチルアミノ〕プロピル〕インドリン−7−カルボキサミドは26μg/kg程度で同様の作用を示した。このように、本発明の化合物は、強力な尿道平滑筋収縮抑制作用を有し、一般的に尿道内圧を低下させる作用に比して、血圧降下に及ぼす影響が軽微であり、尿道平滑筋収縮抑制作用を発現する投与量での血圧低下作用は極めて緩和である。例えば、塩酸プラゾシンと比較した場合、尿道平滑筋に対する作用は血管に対して数倍以上の良好な選択性を示し、中には10倍ないし100倍以上の卓越した選択性を示す化合物もあり、強力な血圧低下または起立性低血圧を惹起することのない排尿困難治療剤として非常に有用な化合物である。
【0053】
前記一般式(II)の化合物は少なくとも1個の不斉炭素を有しており、それぞれの不斉炭素において(R)配置および(S)配置の2つの立体配置が存在するが、いずれの配置の化合物も使用でき、またそれらの混合物も使用できる。前記一般式(II)の化合物の中、不飽和結合を有するものには、EおよびZの幾何学異性が存在するが、いずれの化合物も使用できる。これらの化合物において、尿道内圧低下作用に比して血圧低下作用が緩和である、すなわち、尿道平滑筋に対する選択性の高い化合物が好ましい。
【0054】
また、前記一般式(II)の化合物は3つの置換基を有しており、置換基R1においては置換基としてカルボキシ基を有していてもよい脂肪族アシル基、ヒドロキシアルキル基、脂肪族アシルオキシアルキル基、置換基として低級アルコキシ基,カルボキシ基,低級アルコキシカルボニル基またはアリール置換低級アルコキシカルボニル基を有していてもよい低級アルキル基が好ましく、置換基R2においてはカルバモイル基が好ましく、具体的には、1−アセチル−5−〔2−〔2−〔2−(2,2,2−トリフルオロエトキシ)フェノキシ〕エチルアミノ〕プロピル〕インドリン−7−カルボキサミド、1−ブチリル−5−〔2−〔2−〔2−(2,2,2−トリフルオロエトキシ)フェノキシ〕エチルアミノ〕プロピル〕インドリン−7−カルボキサミド、1−(3−エトキシカルボニルプロピル)−5−〔2−〔2−〔2−(2,2,2−トリフルオロエトキシ)フェノキシ〕エチルアミノ〕プロピル〕インドリン−7−カルボキサミド、4−〔5−〔2−〔2−〔2−(2,2,2−トリフルオロエトキシ)フェノキシ〕エチルアミノ〕プロピル〕−7−カルバモイルインドリン−1−イル〕酪酸、1−(3−メトキシプロピル)−5−〔2−〔2−〔2−(2,2,2−トリフルオロエトキシ)フェノキシ〕エチルアミノ〕プロピル〕インドリン−7−カルボキサミド、1−(4−ヒドロキシブチル)−5−〔2−〔2−〔2−(2,2,2−トリフルオロエトキシ)フェノキシ〕エチルアミノ〕プロピル〕インドリン−7−カルボキサミド、1−(3−ヒドロキシプロピル)−5−〔2−〔2−〔2−(2,2,2−トリフルオロエトキシ)フェノキシ〕エチルアミノ〕プロピル〕インドリン−7−カルボキサミド等をあげることができる。
【0055】
また、特に好ましい化合物として、例えば、1−ブチリル−5−〔2−〔2−〔2−(2,2,2−トリフルオロエトキシ)フェノキシ〕エチルアミノ〕プロピル〕インドリン−7−カルボキサミド、1−(3−エトキシカルボニルプロピル)−5−〔2−〔2−〔2−(2,2,2−トリフルオロエトキシ)フェノキシ〕エチルアミノ〕プロピル〕インドリン−7−カルボキサミド、1−(3−メトキシプロピル)−5−〔2−〔2−〔2−(2,2,2−トリフルオロエトキシ)フェノキシ〕エチルアミノ〕プロピル〕インドリン−7−カルボキサミド、1−(3−ヒドロキシプロピル)−5−〔2−〔2−〔2−(2,2,2−トリフルオロエトキシ)フェノキシ〕エチルアミノ〕プロピル〕インドリン−7−カルボキサミド、(R)−1−ブチリル−5−〔2−〔2−〔2−(2,2,2−トリフルオロエトキシ)フェノキシ〕エチルアミノ〕プロピル〕インドリン−7−カルボキサミド、(R)−1−(3−エトキシカルボニルプロピル)−5−〔2−〔2−〔2−(2,2,2−トリフルオロエトキシ)フェノキシ〕エチルアミノ〕プロピル〕インドリン−7−カルボキサミド、(R)−1−(3−メトキシプロピル)−5−〔2−〔2−〔2−(2,2,2−トリフルオロエトキシ)フェノキシ〕エチルアミノ〕プロピル〕インドリン−7−カルボキサミド、および(R)−1−(3−ヒドロキシプロピル)−5−〔2−〔2−〔2−(2,2,2−トリフルオロエトキシ)フェノキシ〕エチルアミノ〕プロピル〕インドリン−7−カルボキサミドをあげることができる。
