Description

【0001】
【産業上の利用分野】
本発明は抗潰瘍作用を有するプロスタグランジンE1類縁体に関する。
【0002】
【従来の技術】
プロスタグランジン(以下、PGと略称する。)は微量で種々の重要な生理作用を発揮することから、従来より医薬への応用を意図して天然PG及び夥しい数のその誘導体の合成と生物活性の検討が行なわれている。
その中でもPGE1は、細胞保護作用、酸分泌抑制作用などの特徴ある作用を有していることが知られており、このため多数のPGE1類縁体が消化性潰瘍治療薬として検討されてきた。
このうち、本発明化合物に最も構造が近いものとしては特開平7−25847号公報に記載の、(2E)−16−フェノキシ−17,18,19,20−テトラノル−2,3,13,14−テトラデヒドロ−PGE1のメチルエステル、t−ブチルエステルなどの低級アルキルエステルが知られている。これらの化合物は、EP受容体において、EP3受容体に選択的に作用するため、下痢をはじめとする副作用を生じず、かつ優れた抗潰瘍作用を有する化合物として期待されていた。
【0003】
【発明が解決しようとする課題】
しかしながら、上記化合物は経口投与した場合に、エステル部分が加水分解を受けて容易にフリー体に変化してしまう。このフリー体は、EP3受容体に選択的な作用を持たないため、副作用を有し、十分な効果を挙げることができないという欠点があった。
本発明の目的は、従来知られているPGE1類縁体よりも副作用が少なく、かつ強力で持続性に優れた抗潰瘍作用を有する新規なPGE1類縁体を提供することにある。
【0004】
【課題を解決するための手段】
本発明者らは鋭意研究を進めた結果、13,14位に3重結合を有し、かつω鎖の末端位にフェノキシ基を有し、さらに1位のカルボキシル基の代わりに他の置換基を有するある特定のPGE1類縁体が前記課題を解決できることを見いだし、本発明を完成した。

(第1行程)
まず、佐藤らの方法[ジャーナル・オブ・オーガニック・ケミストリー(J.Org.Chem.),第53巻,第5590ページ(1988年)]により公知の式(II)の化合物に、式(III)で示される有機アルミニウム化合物約0.8〜約2.0当量を約−10〜約30℃、好ましくは約0〜約10℃で不活性溶媒(例えばベンゼン、トルエン、テトラヒドロフラン、ジエチルエーテル、塩化メチレン、n−ヘキサンなど)中で反応させることにより立体特異的に式(IV)の化合物が得られる。
原料として使用される上記式(III)の有機アルミニウム化合物は、特開平8−47398号公報記載の方法により調製することができる。
【0017】
(第2行程)第1行程で得られる式(IV)の化合物を、式(V)で表される化合物約0.5〜約4当量とラジカル発生剤(例えばアゾビスイソブチロニトリル、アゾビスシクロヘキサンカルボニトリル、過酸化ベンゾイル、トリエチルボランなど)約0.55〜約2当量、さらにラジカル性還元剤(例えば水素化トリブチルスズ、水素化トリフェニルスズ、水素化ジブチルスズ、水素化ジフェニルスズなど)約1〜約5当量を不活性溶媒(例えばベンゼン、トルエン、キシレン、n−ヘキサン、n−ペンタンなど)中、約−78〜約100℃で反応させ、式(VI)の化合物とする。
【0018】

第2行程で得られる式(VI)の化合物の水酸基の保護基であるt−ブチルジメチルシリル基をプロスタグランジン化学の分野における通常の方法を用いて脱保護し、式(I)の化合物を得る。
上記各工程の生成物は、必要に応じて、それ自体既知の方法により、例えば、シリカゲルカラムクロマトグラフィーなどの方法により反応混合物から分離、精製することができる。

【発明の効果】
本発明の式(I)の化合物は、強い細胞保護作用、酸分泌抑制作用を有し、しかもその持続性に優れている。また、下記試験例より明らかなように、EP受容体に対してEP3受容体に極めて選択的に作用する。そのため、下痢などの副作用を発現せず抗潰瘍作用を選択的に発現させるので、消化性潰瘍を治療する医薬として有用である。
以下、本発明の効果を試験例により具体的に説明する。
【0021】
試験例[EP受容体に対する選択性の検討試験]
EP受容体に対する選択性の検討試験は下記の方法に従って行った(EP1およびEP4受容体は下痢に関係することが報告されており、また、EP3受容体は胃酸分泌作用に関係していることも報告されている。)。
【0022】
マウスEP1,EP2,EP3,EP4の遺伝子を、pdKCR−dhfrと共にpcDNAIにinsertし、α−modification of minimal essential medium (α-MEM) containing 10% FBS,100 mg/l ストレプトマイシン,10.000 U/l ペニシリンG を培地に用いてselection をかけ培養した。subculture は trypsin 処理して細胞を剥がしPBSを加え反応を停止し 1000 r.p.m.,5min, 4℃で遠心した。得られた細胞にα-MEM を加え subculture した。膜調整は、細胞をラバーポリスマンで集め homogenize buffer ( 20mM Tris/HCl pH 7.5 containing 10mM MgCl2, 1 mM EGTA, 0.25 M sucrose, 0.2mM PMSF and 20 μM indomethacin )で Potter-Elvehjem homogenizer を用いてホモジナイスした。これを 800×g, 5min で遠心し、得られたペレットを同 buffer に懸濁した。この上清を先の上清と合わせ 25,000×g, 20 min 超遠心した。ペレットを binding buffer ( 10mM MES/NaOH pH 6.0 containing 1 mM EDTA and 10mM MgCl2 )で再懸濁し膜標本とした。[3H]PGE2 結合は 96 穴 micro well に 25μMの膜蛋白質を含んだ buffer, 検体, [3H]PGE2 を加え 30℃,60 min インキュベートした (EP1 の assay のみ 10 min インキュベート)。反応終了後、CELL HARVESTER を使い Green Mat 11739 上で B/F 分離を行った。リガンド濃度は 5 nM ( EP1 ),2 nM ( EP3 ),4 nM ( EP2,4 ),非特異的結合量は 10μM PGE2 存在下での結合とした。表1 に EP1,EP2,EP3,EP4 受容体発現細胞を用いた置換実験における各薬物の IC50値(nM)を示した。 これらの結果より、比較化合物2はEP1,EP2,EP3,EP4受容体にすべて作用するが、本発明化合物はEP3のみ作用し、他には作用しないことが示された。

[Industrial application fields]
The present invention relates to prostaglandin E having anti-ulcer activity.1Related to analogs.
[0002]
[Prior art]
Since prostaglandins (hereinafter abbreviated as PG) exhibit various important physiological functions in a trace amount, synthesis and biological activity of natural PG and a large number of derivatives thereof have been conventionally intended for pharmaceutical applications. Is being studied.
Among them, PGE1Is known to have distinctive actions such as cytoprotective action, acid secretion inhibitory action, etc.1Analogs have been investigated as therapeutic agents for peptic ulcers.
Among these, the one closest in structure to the compound of the present invention is (2E) -16-phenoxy-17,18,19,20-tetranor-2,3,13,14 described in JP-A-7-25847. -Tetradehydro-PGE1Lower alkyl esters such as methyl ester and t-butyl ester are known. These compounds are EP receptorsThreeSince it acts selectively on the receptor, it has been expected as a compound that does not cause side effects such as diarrhea and has an excellent anti-ulcer action.
[0003]
[Problems to be solved by the invention]
However, when the above compound is administered orally, the ester moiety undergoes hydrolysis and easily changes to a free form. This free body is EPThreeSince it does not have a selective action on the receptor, there is a drawback that it has side effects and a sufficient effect cannot be obtained.
The object of the present invention is to provide a conventional PGE.1Novel PGE having anti-ulcer action with less side effects than analogs, and strong and durable1It is to provide an analog.
[0004]
[Means for Solving the Problems]
As a result of diligent research, the inventors have a triple bond at the 13th and 14th positions, a phenoxy group at the terminal position of the ω chain, and other substituents instead of the carboxyl group at the 1st position. Certain PGE with1The present invention has been completed by finding that an analog can solve the above-mentioned problems.

[0012]
In the present invention, the alkyl group having 1 to 4 carbon atoms refers to a linear or branched alkyl group such as a methyl group, an ethyl group, an n-propyl group, an isopropyl group, an n-butyl group, An isobutyl group, t-butyl group, etc. are mentioned. A cycloalkyl group having 3 to 8 carbon atoms is a cyclopropyl group, a cyclobutyl group, a cyclopentyl group, a cyclohexyl group, a cycloheptyl group, or a cyclooctyl group. A C1-C4 alkoxy group is a methoxy group, an ethoxy group, an isopropoxy group, a t-butoxy group, or the like. The C3-C8 cycloalkoxy group includes a cyclopropoxy group, a cyclopentyloxy group, a cyclohexyloxy group, and the like. Examples of the hydroxyalkyl group having 1 to 4 carbon atoms include a hydroxymethyl group, a hydroxyethyl group, a hydroxybutyl group, and the like. An acyloxy group having 2 to 8 carbon atoms is an acetyloxy group, a propionyloxy group, a cyclohexanecarbonyloxy group, a benzoyloxy group, or the like. Examples of the alkylthio group having 1 to 4 carbon atoms include a methylthio group and an ethylthio group. The alkylsulfinyl group having 1 to 4 carbon atoms includes a methylsulfinyl group, an ethylsulfinyl group, a t-butylsulfinyl group, and the like.
