Description

【0001】
【発明の属する技術分野】
本発明は、線溶促進作用を有し、血栓溶解剤、抗血栓剤として有用なピリミジン誘導体及びそれを有効成分として含む医薬組成物に関する。
【0002】
【従来の技術】
血栓を溶解するためには、プラスミノーゲンアクチベータ(PA)類を投与する療法、すなわち血栓溶解療法(線溶療法)が、現在広く実施されている。線溶系の活性化は、血液線溶系調節因子の前駆体であるプラスミノーゲンをPAがプラスミンに活性化することによって開始され、生じたプラスミンが酵素作用を発現して血栓の構成成分であるフィブリンを分解することによって血栓溶解が進行する。
現在、この線溶療法に使用される血栓溶解剤として、ウロキナーゼ(UK)、組織プラスミノーゲンアクチベータ(t−PA)などの生体内物質、ストレプトキナーゼ(SK)、スタフィロキナーゼ(SAK)などの菌体産生物質及びそれらの遺伝子組換え体等が知られている。しかし、これら既存の血栓溶解薬は全てタンパク製剤であるため、血中半減期が短く、速やかに肝臓で代謝され、又、生体内に阻害因子が存在するため、血栓の生じている局所において血栓溶解作用を発現させるためには大量投与を必要とする。臨床において、投与量が多いほど再灌流率が高いことが報告されているが、このような血栓溶解剤の一過性の大量投与は、全身的に血栓溶解活性を著しく高め、血栓塞栓部位を開通させることが期待される一方、副作用として重篤な出血症状が認められる。これらの血栓溶解剤の投与により、一時的に塞栓部位を開通させても、再閉塞を生じ易いことが大きな問題となっている。
最近PAの強力なインヒビターであるタイプ1プラスミノーゲンアクチベータインヒビター(PAI−1)の活性を阻害するベンゾチオフェン誘導体(特許文献1)、ジケトピペラジン誘導体(特許文献2)やPAI−1の生産を抑制するプロスタグランジン化合物(特許文献3)、2,5−ピロリジンジオン誘導体(特許文献4)、3−ブテン酸誘導体(特許文献5)等が開発され、血栓に関連して起こる疾患の予防、もしくは治療薬としての研究が行われているが、未だ開発途上である。また、これらの公知化合物には本発明化合物の特徴の一つであるフェニル置換ピリミジン骨格を有するものはない。

本発明の前記式(1)で表される化合物は、いずれも公知の方法により合成することができる。以下に、本発明の前記式(1)で表される化合物の代表的製造方法を示す。但し、これらは例であり、その他の既知の方法を用いることもできる。
ピリミジン誘導体の一般的な合成法として、G.W.Kenner,”Pyrimidine and Its Derivatives”,in R.C.Elderfield,”Heterocyclic compound”,6,234.,JohnWilley (1957)などの文献に記載されている方法があり、これらの方法に基づき本発明の化合物の合成法は、下記スキームAにより示すことができる。

[式中、Aは本発明の前記した置換基a自体を、或いはaに変換でき
得る置換基であることを意味する。Rは低級アルキル基を意味する。]
式(5)で示されるアミン化合物とシアナミドとの反応(特開昭57−179146号公報,米国特許3406185号公報参照)によって得られる式(7)で示されるグアニジン若しくはそれらの酸付加塩と、式(8)で示されるベンゾイル酢酸エステル、或いはそれらの等価体を溶媒中、或いは無溶媒で適当な塩基の存在下、室温から150℃で反応させることにより、式(9)で示されるピリミジン誘導体を製造することができる。溶媒として、例えばメタノール、エタノール、或いはアセトニトリルなどが挙げられる。塩基として、ナトリウム、アルコキシアルカリ金属(例えばナトリウムメトキシド)、或いは炭酸カリウム、炭酸ナトリウム、水酸化ナトリウムなどの無機塩基、或いはトリエチルアミン、ピリジン、ピペリジンなどの有機塩基が挙げられる。
式(9)で示される化合物はピリミジノール体として表記されているが、このものはピリミジノン体と互変異性体の関係にあり、特に断らない限り本発明において、互変異性体の両方を示し、いずれの異性体も本発明の範囲に含まれる。

前記した式(9)で示される化合物のピリミジン環上及び、側鎖A中の水酸基はそれぞれ下記スキームBに従って他の官能基に変換することができる。

式(9−1)で示される化合物をDMF等の非プロトン性の極性溶媒中、炭酸アルカリ等の塩基の存在下、式(10)で示されるハロゲン化体を室温下、或いは加熱下で反応させ、式(11)で示されるピリミジン環上の水酸基が変換された化合物に誘導することができる。式(12)で示される化合物を用い、側鎖A中の水酸基の変換も同様にして成されるが、式(13)で示される化合物のAlk−B1基がベンジル基の場合、ピリミジン環上の水酸基の保護基として扱うことができ、脱保護(還元)することにより、側鎖A中の水酸基のみが変換された式(14)で示される化合物の合成が可能である。更に、式(15)で示されるハロゲン化体を反応させ、式(16)で示される化合物への変換もできる。
保護基の導入及び脱離は、例えば、T.W.Green,”Protective Groups in Organic Synthesis,2nd Ed.”,John Willey & Sons,1991に記載さており、これらの常法に従って行われる。

式(9−2)で示される化合物の水酸基をベンジル基等で保護した後、加水分解することで得られる式(19)で示される化合物のカルボキシ基はアミンと縮合させることができる。即ち、式(19)で示される化合物に適当な溶媒中、4−ジメチルアミノピリジン(DMAP)、1−ヒドロキシベンゾトリアゾール・一水和物(HOBt)、p−ニトロフェノール、トリエチルアミンなどの添加剤存在下若しくは非存在下、1−(3−ジメチルアミノプロピル)−3−エチルカルボジイミド・塩酸塩(WSC・HCl)、N,N’−ジシクロヘキシルカルボジイミド(DCC)、ベンゾトリアゾール−1−イル−オキシ−トリス−(ジメチルアミノ)ホスホニウム ヘキサフルオロホスフェート(BOP試薬)、ヨウ化 2−クロロ−1−メチルピリジニウム、ジフェニルホスホリルアジドなどの縮合剤、及び式(20)で示されるアミノ誘導体と反応させることにより式(21)で示されるアミド化合物に変換できる。或いは、適当な溶媒中若しくは無溶媒で、トリエチルアミン、ピリジンなどの塩基存在下若しくは非存在下、塩化チオニル、塩化ホスホリルなどのハロゲン化剤と反応させて酸ハロゲン化誘導体とした後、アミン誘導体と反応させることにより対応するアミドに変換することができる。

前記式(1)で示される化合物の置換基a又はb中に存在するカルボン酸エステルは常法に従い、アルカリ加水分解等により、カルボン酸のアルカリ塩に、若しくは生成したアルカリ塩を酸析することで遊離カルボン酸に変換することができる。前記式(1)で示される化合物中に低級アルコキシカルボニル基がある場合、それ自体本発明の医薬組成物を構成する一つの形態であるが、このようにして、本発明のもう一つの形態である対応するカルボン酸、及びそのアルカリ塩に変換することもできる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a pyrimidine derivative having a fibrinolysis-promoting action and useful as a thrombolytic agent and an antithrombotic agent, and a pharmaceutical composition containing the same as an active ingredient.
[0002]
[Prior art]
In order to dissolve thrombus, a therapy for administering plasminogen activators (PAs), that is, thrombolytic therapy (fibrinolytic therapy) is currently widely practiced. Activation of the fibrinolytic system is initiated by the activation of plasminogen, a precursor of a blood fibrinolytic regulatory factor, by PA to plasmin. Decomposes to promote thrombolysis.
At present, thrombolytic agents used in this fibrinolytic therapy include in vivo substances such as urokinase (UK) and tissue plasminogen activator (t-PA), streptokinase (SK) and staphylokinase (SAK). Bacterial cell-producing substances and their genetically modified products are known. However, since these existing thrombolytic drugs are all protein preparations, they have a short half-life in blood and are rapidly metabolized in the liver. In order to exert a lytic effect, a large amount of administration is required. In clinical practice, it has been reported that the higher the dose, the higher the reperfusion rate.However, such a transient large dose of a thrombolytic agent markedly enhances the thrombolytic activity systemically and reduces the thromboembolic site. While it is expected to be opened, severe side effects of bleeding are observed. A major problem is that re-occlusion is likely to occur even when the embolization site is temporarily opened by administration of these thrombolytic agents.
Recently, production of benzothiophene derivatives (Patent Document 1), diketopiperazine derivatives (Patent Document 2) and PAI-1 which inhibit the activity of type 1 plasminogen activator inhibitor (PAI-1), which is a potent inhibitor of PA, Prostaglandin compounds (Patent Literature 3), 2,5-pyrrolidinedione derivatives (Patent Literature 4), 3-butenoic acid derivatives (Patent Literature 5), and the like have been developed to prevent diseases associated with thrombus, Or research is being conducted as a therapeutic agent, but it is still under development. Further, none of these known compounds has a phenyl-substituted pyrimidine skeleton which is one of the characteristics of the compound of the present invention.
