Description

本発明は、医薬品、食品、飼料、化粧品等の様々な分野で使用することが可能な新規抗炎症剤に関する。更に詳細には、アスコピロンを含有する抗炎症剤に関する。   The present invention relates to a novel anti-inflammatory agent that can be used in various fields such as pharmaceuticals, foods, feeds, and cosmetics. More specifically, the present invention relates to an anti-inflammatory agent containing ascopyrone.

アスコピロンは1,5−D−アンヒドロフルクトースを出発物質として酵素反応により調製できることが報告されている(特許文献1、特許文献2および特許文献3参照)。元来、アスコピロンはある種の子嚢菌により生合成されることが知られており(非特許文献1参照)、Pezizales目(例えば、Picaria leiocarpaおよびAnthracobia melaloma)ならびにTuberales目(例えば、Tuber melanosporum)の菌体抽出液を1,5−D−アンヒドロフルクトースに作用させ調製できることも報告されている。また、菌の種類により生合成されるアスコピロンの構造も異なる。
アスコピロンの一つであるアスコピロンP(2−Hydroxymethyl−5−hydroxy−2,3−dihydro−4H−pyran−4−one)は、1978年および1981年に、米国の科学者のグループによって、アミロペクチン、アミロース、及びセルロースの熱分解で合成されることが報告され、有機合成の出発物質として使用された。(非特許文献2および非特許文献3参照)。
アスコピロンPは抗酸化活性(特許文献4参照)、抗菌活性を有することが報告されている(特許文献5および特許文献6参照)。
It has been reported that ascopyrone can be prepared by enzymatic reaction using 1,5-D-anhydrofructose as a starting material (see Patent Document 1, Patent Document 2 and Patent Document 3). Originally, it is known that ascopyrone is biosynthesized by certain ascomycetes (see Non-Patent Document 1), and the order of Pezzales (eg, Picaria leiocarpa and Anthracobiala meloma) and Tuberales (eg, Tuber melanosporum). It has also been reported that the bacterial cell extract can be prepared by acting on 1,5-D-anhydrofructose. In addition, the structure of ascopyrone that is biosynthesized depends on the type of fungus.
Ascopyrone P (2-Hydroxymethyl-5-hydroxy-2,3-dihydro-4H-pyran-4-one), which is one of the ascopyrones, was introduced by a group of American scientists in 1978 and 1981 by the group of amylopectin, It was reported to be synthesized by pyrolysis of amylose and cellulose and used as a starting material for organic synthesis. (See Non-Patent Document 2 and Non-Patent Document 3).
Ascopyrone P has been reported to have antioxidant activity (see Patent Document 4) and antibacterial activity (see Patent Document 5 and Patent Document 6).

現在、各種疾患によって誘起される炎症の治療には、抗炎症剤としてステロイド剤および非ステロイド系抗炎症剤が使用されている。前者は各種疾患における諸症状を顕著に改善するが、投与し続けるにつれその効果は次第に低減し、また、様々な副作用を誘発する危険性があるなど、多くの問題点を有している。また、後者においては、炎症症状を一時的に抑制する程度ものである。従って、確実に炎症症状を抑制でき、且つ、安全な抗炎症剤が切望されている。

Currently, steroids and nonsteroidal anti-inflammatory agents are used as anti-inflammatory agents in the treatment of inflammation induced by various diseases. The former significantly improves various symptoms in various diseases, but the effect gradually decreases as the administration continues, and there are many problems such as risk of inducing various side effects. In the latter case, the inflammatory symptoms are temporarily suppressed. Therefore, a safe anti-inflammatory agent that can surely suppress inflammatory symptoms and is desired is desired.

実施例1[アスコピロンPの抗炎症作用]
マウスの耳介皮膚に化学物質を直接塗布すると、急性炎症により耳介の浮腫が誘発されることが知られていることから、このモデルマウスを用いて抗炎症効果を評価した。
マウス(BALB/c、6週齢、メス、n=6)の耳にクロトンオイルを塗布し、その後PBS、アスコピロンP(20mg/ml)をそれぞれ腹腔内投与(250μl)した。24時間後、耳介を測定しその浮腫の程度から抗炎症効果を評価した(図1)。なお、図中では、クロトンオイルを塗布していない無処理のマウス(control)の耳介の厚さと比較した耳介の膨張度を示している。
クロトンオイルを塗布して24時間後の耳介の腫脹は、PBS投与群に対し、アスコピロンP投与群のほうが明らかに抑えられていた。
Example 1 [Anti-inflammatory action of Ascopilone P]
Since it is known that when a chemical substance is directly applied to the auricle skin of a mouse, the edema of the auricle is induced by acute inflammation, the anti-inflammatory effect was evaluated using this model mouse.
Croton oil was applied to the ears of mice (BALB / c, 6 weeks old, female, n = 6), and PBS and Ascopyrone P (20 mg / ml) were then administered intraperitoneally (250 μl). After 24 hours, the auricle was measured and the anti-inflammatory effect was evaluated from the degree of edema (FIG. 1). In the figure, the degree of expansion of the auricle is shown in comparison with the thickness of the auricle of an untreated mouse (control) not coated with croton oil.
The swelling of the pinna 24 hours after application of croton oil was clearly suppressed in the Ascopirone P administration group compared to the PBS administration group.
