Description

本発明は新規なペニシラミンアミド誘導体に関する。より詳しくは、蛋白分解酵素阻害活性、特に、抗トロンビン作用を有するペニシラミンアミド誘導体及びその塩、並びにそれらを有効成分とする蛋白分解酵素阻害剤に関する。 The present invention relates to a novel penicillamine amide derivative. More specifically, the present invention relates to a proteolytic enzyme inhibitory activity, particularly a penicillamine amide derivative having an antithrombin action and a salt thereof, and a proteolytic enzyme inhibitor containing them as an active ingredient.

生体内に種々の蛋白分解酵素が存在していることは周知のとおりである。例えば、トロンビン、Xa因子、IXa因子、VII a因子、トリプシン、プラスミン、組織プラスミノーゲンアクチベーター、カリクレイン、補体中のC1酵素あるいはC3/C5コンベルターゼ、トリプターゼなどの一群のセリンプロテアーゼの存在が知られている。また、これらの蛋白分解酵素が何らかの理由によって異常に活性化されると種々の疾患が引き起こされることも知られている。従って、これらの蛋白分解酵素に対して阻害活性を示す物質は医薬として有用であることが期待される。  It is well known that various proteolytic enzymes exist in the living body. For example, the presence of a group of serine proteases such as thrombin, factor Xa, factor IXa, factor VIIa, trypsin, plasmin, tissue plasminogen activator, kallikrein, complement C1 enzyme or C3 / C5 convertase, tryptase, etc. It has been. It is also known that various diseases are caused when these proteolytic enzymes are activated abnormally for some reason. Therefore, it is expected that substances showing inhibitory activity against these proteolytic enzymes are useful as pharmaceuticals.

例えば、抗トロンビン剤が血栓症の治療剤として有効であることが知られており、抗トロンビン作用を有する蛋白分解酵素阻害剤の開発が進められている。しかしながら、この阻害剤は、生体内での安定性、トロンビン同族のセリンプロテアーゼとの間の選択性、経口投与時の抗トロンビン活性の低下などいくつかの点で問題があり、医薬品として実用に供するには十分ではない。 For example, it is known that an antithrombin agent is effective as a therapeutic agent for thrombosis, and a proteolytic enzyme inhibitor having an antithrombin action is being developed. However, this inhibitor has problems in several respects, such as in vivo stability, selectivity with a serine protease of the thrombin family, and reduction of antithrombin activity upon oral administration, and is used as a pharmaceutical product. Is not enough.

また、蛋白分解酵素阻害剤としてアルギニン誘導体を含むトリペプチド誘導体が知られている。例えば、D−フェニルアラニル−L−プロリル−L−アルギナールがトロンビン阻害剤として知られている(たとえば非特許文献1)。しかしながら、この化合物は生体内では比較的不安定である(非特許文献2)。同様に、アルギナール誘導体(特許文献1,2)、アミジノフェニルアラニン誘導体(非特許文献3)、アルギニンケトアミド誘導体(特許文献3)、及びホウ素化合物誘導体(たとえば非特許文献4、特許文献4、5、6)などの報告があるが、トロンビン同族セリンプロテアーゼ、特にトリプシンとの間での酵素選択性が低いという問題を有している。トロンビン選択的な阻害剤としてグアニジン誘導体(特許文献7)や4置換シクロヘキシルアミン誘導体(特許文献8)が報告されているが、いずれも経口投与で有効性を示すものではない。

Further, tripeptide derivatives containing arginine derivatives are known as protease inhibitors. For example, D-phenylalanyl-L-prolyl-L-arginal is known as a thrombin inhibitor (for example, Non-Patent Document 1). However, this compound is relatively unstable in vivo (Non-patent Document 2). Similarly, arginal derivatives (Patent Documents 1 and 2), amidinophenylalanine derivatives (Non-Patent Document 3), arginine ketoamide derivatives (Patent Document 3), and boron compound derivatives (for example, Non-Patent Document 4, Patent Documents 4 and 5, 6) and the like, but has a problem that the enzyme selectivity with thrombin homologous serine protease, particularly trypsin is low. Although guanidine derivatives (Patent Document 7) and 4-substituted cyclohexylamine derivatives (Patent Document 8) have been reported as thrombin-selective inhibitors, none of them shows efficacy by oral administration.
