環状アデノシン 3', 5' —一リン酸 (以下 c一 AMPと略記する。 ) は、 生体 内のセカンドメッセンジャーとして細胞機能、 細胞増殖及び細胞分化に関与して いる。 この c—AMPを分解してアデノシン 5, 一一リン酸 (以下 5' -AMP と略記する。 ) に変換する酵素が、 環状アデノシン 3 ', 5' —一リン酸フォスフ ォジエステラーゼ (以下フォスフォジエステラーゼと略記する。 ) である。 この 酵素の活性を阻害する物質は、 細胞内の c一 AMP及び c—GMPの量を増加さ せ、 細胞応答を制御する作用を有する。 具体的には、 このようなフォスフオジェ ステラーゼ阻害剤は、 平滑筋の弛緩作用、 白血球の細胞活性化の抑制作用等を示 すことが一般的に知られている。 Cyclic adenosine 3 ', 5'-monophosphate (hereinafter abbreviated as c-AMP) is involved in cell function, cell proliferation and cell differentiation as a second messenger in vivo. An enzyme that degrades c-AMP to adenosine 5, monophosphate (hereinafter abbreviated as 5'-AMP) is a cyclic adenosine 3 ', 5'-monophosphate phosphodiesterase (hereinafter referred to as phospho-adenosine). It is abbreviated as fodiesterase. Substances that inhibit the activity of this enzyme increase the amount of c-AMP and c-GMP in cells. It has the effect of controlling the cellular response. Specifically, it is generally known that such a phosphogesterase inhibitor exhibits a smooth muscle relaxing action, a leukocyte cell activation suppressing action, and the like.
これらの作用は、 種々の細胞および組織に分布するフォスフォジエステラーゼ アイソザィムの個々の抑制に起因することが一般的に知られている。  It is generally known that these effects result from individual suppression of phosphodiesterase isozymes distributed in various cells and tissues.
従来のフォスフォジエステラーゼ阻害剤は、 その阻害活性が満足すべきもので なかったり、 あるいはアイソザィムに対する選択性が低いため実際の使用にあた つて副作用の面で満足すべきものではなかった。 したがって、 低濃度でもフォス フォジエステラーゼ阻害活性が強く、 好ましくはさらにアイソザィムに対する選 択性の高いフォスフォジエステラーゼ阻害剤の開発が望まれている。  Conventional phosphodiesterase inhibitors have either been unsatisfactory in their inhibitory activity or have low selectivity for isozymes, so that they have not been satisfactory in terms of side effects in actual use. Therefore, it is desired to develop a phosphodiesterase inhibitor which has a strong phosphodiesterase inhibitory activity even at a low concentration and preferably has a high selectivity for isozymes.
