【産業上の利用分野】
本発明は、一般式
【化7】
(式中、R1、R2、R3、R4、R5及びR6は水素原子又はアルキル基であり、R1〜R6が同時に水素原子とはならない。又、R1とR2及びR4とR5は一体となり、環状アルキル基を形成することもできる。R7はアルキル基である。Arは無置換又は−R8で置換されたアリール基であり、R8はアルコキシル基、−OSi(R9R10R11)又はリン酸塩基で表される基であり、R9、R10及びR11はアルキル基である。)で表される1,2−ジオキセタン誘導体及びその中間体に関する。前記一般式(I)で表される1,2−ジオキセタン誘導体は化学発光を誘導できる化合物であり、例えば免疫測定等の基質として利用することができる。
【0002】
【従来の技術】
旧来より、1,2−ジオキセタン誘導体が種々合成されたが殊に3位にスピロアダマンチル基が結合した化合物は化学発光基質として有用であることが知られている(例えば、特公平5−21918号公報明細書及び特公平5−45590号公報明細書参照)。
【0003】
【発明が解決しようとする課題】
しかしながら、従来の化合物は、安定性、あるいは発光持続性に対して充分な効果があるとは言えず、その改良が望まれていた。
【0004】
【課題を解決するための手段】
本発明者は、従来の化合物の持つ欠点を克服すべく検討した結果、前記一般式(I)で表される1,2−ジオキセタン誘導体を見出し本発明を完成したものである。
【0005】
本発明の前記一般式(I)で表される1,2−ジオキセタン誘導体は以下の反応式に従い製造することができる。
【化8】
(式中、R1〜R7及びArは前記と同じである。R12及びR13はアルキル基又は一体となり環状アルキル基を形成し得る。)
【0006】
以下、本発明を詳細に説明するにあたって、本発明で「アルキル基」とは、置換基を有していてもよい炭素数1〜20個の直鎖状又は分枝鎖状のアルキル基をいい、そのアルキル基は、メチル、エチル、プロピル、ブチル、ペンチン、ヘキシル、ヘプチル、オクチル、ノニル、デシル、ウンデシル、ドデシル、テトラデシル、ペンタデシル、ヘキサデシル、ヘプタデシル、オクタデシル、ノナデシル、イコデシルの直鎖の基及び前記のアルキル基が適宜分枝状に結合した基をいう。前記置換していてもよい基とは、例えば、ヒドロキシル基、アルコキシル基、アリール基、複素環基等である。そのアルコキシル基としては、例えばメトキシ、エトキシ、プロポキシ、ブトキシ、ペンチルオキシ、ヘキシルオキシ、メトキシエトキシ、メトキシプロポキシ、エトキシエトキシ、エトキシプロポキシ、メトキシエトキシエトキシ基等であり、またそのアリール基としては、例えば、フェニル、ナフチル基等であり、その複素環基としては、フリル、チエニル、ピリジル基等である。
【0007】
また、本発明で「アルコキシル基」とは、前記したアルキル基に置換してもよいアルコキシル基と同じであり、更に本発明で「アリール基」とは、フェニル、ナフチル基等の芳香族炭化水素基及び環内に窒素、酸素あるいは硫黄原子を有するヘテロアリール基を指すものである。
【0008】
(第1−1工程)
本工程は、一般式(II)で表される芳香族カルボン酸エステルと一般式(III)で表されるケトンとを反応させ、一般式(V)で表されるエノールエーテル誘導体を製造するものである。
【0009】
ここで、一般式(II)中に示した置換基について言及する。まず、Arは前記した如くアリール基を表し、そのアリール基は−R8で表される基により置換されているものである。R8で表される基としては、前記した如く、アルコキシル基、−OSi(R9R10R11)を挙げることができる。R9、R10及びR11は同一或いは異なっていてもよく、前記したアルキル基を例示することができる。
【0010】
前記一般式(II)で表される芳香族カルボン酸エステルの−R8が置換した化合物のうち、−OSi(R9R10R11)の置換した化合物は、
【化9】
(式中、R7)は前記と同じである。)を原料とすることにより対応するシリル化剤より容易に製造できる(参考例参照)。又、R8がアルキル基を持つ化合物は工業的に入手容易な化合物である。
【0011】
一方、一般式(III)で表されるケトンも入手容易な化合物である。
【0012】
反応はチタンの存在下に行うことを必須の要件とするものである。
【0013】
通常、チタンは塩化チタン等のハロゲン化チタンを水素化リチウムアルミニウム等の還元剤及びトリエチルアミン等の塩基を用いて還元状態を形成させ、反応に供することが好ましい。
【0014】
反応を行うにあたってはテトラヒドロフラン(THF)等の有機エーテル中で行うことができる。
【0015】
反応は0〜100℃で進行するが、THFの還流下に行うことが操作及び反応性の観点から好ましい。
【0016】
(第1−2工程)
本工程は一般式(IV)で表されるアリールメチルホスホネートと前記一般式(III)で表されるケトンとを反応させ前記一般式(V)で表されるエノールエーテル誘導体を製造するものである。
【0017】
前記一般式(IV)で表されるアリールメチルホスホネートは前記特公平5−45590号に記載の方法に従い容易に製造することができる化合物である。
【0018】
尚、前記一般式(V)においてArに置換したR8が低級アルコキシル基の場合には水酸基に置換し、次いでシリル化あるいはリン酸化反応を行い第2工程の原料とすることもできる。
【0019】
(第2工程)
本工程は一般式(V)で表されるエノールエーテル誘導体に一重項酸素を反応させ前記一般式(I)で表される1,2−ジオキセタン誘導体を製造するものである。
【0020】
一重項酸素との反応は、前記一般式(V)で表されるエノールエーテル誘導体をジクロロメタン、ジクロロエタン、四塩化炭素、アルコール等の溶媒に溶解し、メチレンブルー、ローズベンガル、テトラフェニルポルフィン等の光増感剤の共存下、酸素雰囲気の下で可視光照射を行うことにより達成される。尚、反応は−80℃〜0℃で行うものである。

[Test Example 1]
3-isopropoxy-4,4-diisopropyl-3- [3 ′-(phosphoryloxy) phenyl] -1,2-dioxetane disodium salt (compound [40]) obtained in Example 26 was added at 0.2 mg / After dissolving in 0.1 M diethanolamine-hydrochloric acid buffer (pH 10.0) containing 1 mM magnesium chloride and 0.05% sodium azide so as to have a concentration of ml, 300 μl of this solution was added to the assay cartridge. And incubated (90 minutes). After incubation, an alkaline phosphatase solution for EIA (Boehringer Mannheim) (3 mg / 0.3 ml) was added to 50 mM containing 0.15 M sodium chloride, 1 mM magnesium chloride, 0.1 mM zinc chloride and 0.1% sodium azide. After 154-fold dilution with Tris / Cl buffer (pH 7.2), an additional 10Five20 μl of enzyme solution prepared by doubling dilution was added, and after stirring, the amount of luminescence was measured over time at 37 ° C.
[0188]
For comparison, the amount of luminescence of commercially available AMPPD was measured under the same conditions. The result is shown in FIG.
[0189]
[Test Example 2]
1 mg of 3-isopropoxy-4,4-diisopropyl-3- [3 ′-(phosphoryloxy) phenyl] -1,2-dioxetane disodium salt (compound [40]) obtained in Example 26 was dissolved in methanol d.Four(0.35 ml) was dissolved and heated in a constant temperature bath at 60 ° C. Every 2-3 hours1HNMR was measured. As a result, the half-life of 3-isopropoxy-4,4-diisopropyl-3- [3 ′-(phosphoryloxy) phenyl] -1,2-dioxetane disodium salt (compound [40]) at 60 ° C. was 14 . Estimated 3 hours.
[0190]
Commercially available AMPPD (3- (2′-spiroadamantane) -4-methoxy-4- (3 ″ -phosphoryloxy) phenyl-1,2-dioxetane disodium salt) was also measured in the same manner, and was halved at 60 ° C. The period was estimated to be 5.5 hours.

【The invention's effect】
The 1,2-dioxetane derivative of the present invention is characterized by excellent thermal stability and high emission persistence. In other words, there is no need for freezing storage or the like for storage, and it is possible to save troubles such as adjustment or temperature management when starting light emission. Furthermore, since stable light emission continues after the start of light emission, the obtained data is stable and reproducibility is high. Further, when measuring the amount of luminescence, it is not necessary to use a highly sensitive measuring device, and it can be measured using an inexpensive device.
[0192]
The 1,2-dioxetane derivative of the present invention can be synthesized from a readily available compound, and the synthesis method is generally widely used. Therefore, a large amount of production is easy and can be supplied at low cost.
[Brief description of the drawings]
FIG. 1 shows light emission using 3-isopropoxy-4,4-diisopropyl-3- [3 ′-(phosphoryloxy) phenyl] -1,2-dioxetane disodium salt (compound [40]) and alkaline phosphatase. It is a figure which shows the relationship of the emitted light intensity at the time of time, and time. The results of AMPPD are also shown in the comparison.
