Description

【0001】
【発明の属する技術分野】
本発明は、三環性1,2−ジオキセタン誘導体に関する。本発明の三環性1,2−ジオキセタン誘導体は化学発光を誘導することができる化合物であり、例えば免疫測定等の基質として使用することができる。
【0002】
【従来の技術】
1,2−ジオキセタン誘導体は、従来より種々合成されており、特に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、特許文献1、特許文献2参照)。また、本発明者らが既に製造したものとして、各種の化合物が知られている(例えば、特許文献3〜6参照)。これらの1,2−ジオキセタン誘導体は、リン酸エステル基などの酵素認識部位を有しており、酵素によってトリガリングされることにより発光する。これら一連の化合物は、免疫反応後に固相に吸着している抗原または抗体に標識された酵素の活性を化学発光反応で検出する方法に用いられる。この方法に用いられる1,2−ジオキセタン誘導体は一般に発光半減期が長く、短時間・高感度測定する上で問題となっていた。

【発明が解決しようとする課題】
1,2−ジオキセタン誘導体に関しては前記のように様々な検討がなされ、種々の化合物が創出されている。しかしながら、臨床検査等の分野で応用するためには化合物自体が安定で取扱いが容易であり、短時間・高感度化のために、発光収率が良いばかりではなく、発光半減期の短い化合物つまり、短時間で発光飽和する性能が要求され、従来の化合物よりもさらに優れた化合物の創出が望まれていた。
【0005】
【課題を解決するための手段】
本願発明者らは、前記のような状況の下、従来化合物よりもさらに優れた化合物を創出するために鋭意検討した結果、安定な骨格を有しており、かつ発光収率も高く、さらに発光半減期が短い三環性1,2−ジオキセタン誘導体を合成し、本発明を完成したものである。

BACKGROUND OF THE INVENTION
The present invention relates to tricyclic 1,2-dioxetane derivatives. The tricyclic 1,2-dioxetane derivative of the present invention is a compound capable of inducing chemiluminescence, and can be used as a substrate for immunoassay, for example.
[0002]
[Prior art]
Various 1,2-dioxetane derivatives have been conventionally synthesized, and it is known that a compound having a spiroadamantyl group bonded to the 3-position is particularly useful as a chemiluminescent substrate (for example, Patent Document 1, Patent Document) 2). Moreover, various compounds are known as what the present inventors already manufactured (for example, refer patent documents 3-6). These 1,2-dioxetane derivatives have an enzyme recognition site such as a phosphate group, and emit light when triggered by the enzyme. These series of compounds are used in a method for detecting the activity of an enzyme labeled with an antigen or antibody adsorbed on a solid phase after an immune reaction by a chemiluminescence reaction. The 1,2-dioxetane derivatives used in this method generally have a long luminescence half-life, which has been a problem for short-time, high-sensitivity measurements.

[Problems to be solved by the invention]
As described above, various studies have been made on 1,2-dioxetane derivatives, and various compounds have been created. However, the compound itself is stable and easy to handle for application in the field of clinical tests, etc. In addition to a good luminescence yield for short time and high sensitivity, Therefore, the ability to saturate light emission in a short time is required, and the creation of a compound superior to conventional compounds has been desired.
[0005]
[Means for Solving the Problems]
The inventors of the present application have made extensive studies in order to create a compound superior to the conventional compounds under the above-mentioned circumstances. As a result, the inventors have a stable skeleton and a high emission yield, and further emit light. A tricyclic 1,2-dioxetane derivative having a short half-life was synthesized and the present invention was completed.
