薬理試験例1:全身性エリテマトーデスモデル動物MRL lpr/lprマウスに対する作用
全身性エリテマトーデスのモデルとして、MRL lpr/lprマウスを用い、リンパ腫脹を指標にして、本発明の自己免疫疾患の予防・治療剤の自己免疫疾患抑制作用を評価した。
メスのMRL lpr/lprマウスを1群10匹として用いた。11週齢から、溶媒(10%ジメチルスルフォキシド及び40%ポリエチレングリコール#400含有生理食塩水)にα-C-GalCer又はα-S-GalCerを溶解して、100μg/体重kgの割合で1週間に2回(火曜日と金曜日)、21日間腹腔内投与した。また、対照には同量の上記溶媒を投与した。投与開始後、1週間に2回腋窩部リンパ節を触診し、リンパ節腫脹進展を経時的に観察した。なお、リンパ節の腫脹の程度は、0、1、2、3の4段階のスコア−化によって評価し、左右腋窩部のスコア−の合計をリンパ節腫脹インデックスとして示した。
【0021】
各群のリンパ腫脹インデックスの経時変化を図1に示した。溶媒投与群では投与開始直後から経時的にリンパ節が腫脹した。α-C-GalCer投与群及びα-S-GalCer投与群は、溶媒投与群に比し腫脹が抑制された。この結果より、α-C-GalCer及びα-S-GalCerはMRL lpr/lprのリンパ節腫脹を抑制することが判明した。自己免疫異常動物であるMRL lpr/lprマウスは、ヒト全身性エリテマトーデスのモデル動物である(Clin.Immunol.,28, 1558-,1996)ことから、α-C-GalCer及びα-S-GalCerは全身性エリテマトーデスの治療に有効であると考えられる。
【0022】
薬理試験例2:デキストラン硫酸ナトリウムDSS誘発潰瘍性大腸炎に対する作用
潰瘍性大腸炎のモデルとして、4% DSS飲水投与による大腸炎モデルを用い、生存率及び体重変化を指標にして、本発明の自己免疫疾患の予防・治療剤の自己免疫疾患抑制作用を評価した。
CDF1マウスを1群10匹として用いた。6週齢から飲料水に4%(W/V)となるようにDSSを溶解して自由摂水させた。4%DSS溶液を与え始めた翌日から1週間に2回、上記の薬理試験例1で用いた溶媒又はα-C-GalCer又はα-S-GalCerを、100μg/体重kgの割合で腹腔内投与し、28日後までの生存率を観察した。
【0023】
各群の生存率の経時推移を図2に示した。α-C-GalCer投与群及びα-S-GalCer投与群では、無処置群に比べ、有意な生存期間の延長が認められた。デキストラン硫酸ナトリウム誘発潰瘍性大腸炎モデルはヒト潰瘍性大腸炎のモデルとして汎用されている(Gastroenterology,109,1344-,1995)。従って、α-C-GalCer及びα-S-GalCerは潰瘍性大腸炎の治療に有効であると考えられる。
【0024】
薬理試験例3:多発性硬化症モデルであるマウス実験的自己免疫性脳脊髄炎に対する作用
多発性硬化症のモデルとして、実験的自己免疫性脳脊髄炎モデルマウスの生存率及び体重変化を指標にして、本発明の自己免疫疾患の予防・治療剤の自己免疫疾患抑制作用を評価した。
SJLマウス(日本SLC(株))を1群10匹として用いた。6週齢でミエリン塩基性タンパク質200μgと結核菌(Mycobacterium tuberculosisi)H37Raを不完全フロイントアジュバントに加えてエマルジョンを作製し、第0日目と第7日目に各マウスに皮下注射することで免疫した。さらに、第0日目と第2日目に500ngの百日咳毒素(pertussis toxin)を腹腔内投与して、マウスに自己免疫性脳脊髄炎を誘導した。溶媒又はα-S-GalCerを、100μg/体重kgの割合で1週間に2回腹腔内投与し、各マウスの発症の程度を毎日観察した。
【0025】
溶媒投与群においては10例中4例の発症が認められたが、α-S-GalCer処置群では10例中で1例発症したのみであった。α-S-GalCerは、マウスにおける実験的自己免疫性脳脊髄炎の発症を抑制することが判明した。このモデルはヒト多発性硬化症のモデルである(Acadenic Press Inc.,1,1-,1994)。従って、多発性硬化症の治療に有効であることを示す。
【0026】
【発明の効果】
本発明の自己免疫疾患の予防・治療剤は、優れた自己免疫疾患の抑制作用又は免疫抑制作用を有し、またグコシダーゼ代謝、酸・塩基に安定で、且つ室温で長期保存できる利点を有する。

[0016]
[Formula 4]
Figure 0004410996
[0017]
That is, the compound (A) and the compound (B) were subjected to Wittig reaction to obtain a compound (C). The obtained compound (C) was allowed to act on palladium-carbon under a hydrogen stream to simultaneously reduce the double bond portion and remove Bn group to obtain α-C-GalCer.
Moreover, said α-S-GalCer was produced by the following process.
[0018]
[Chemical formula 5]
Figure 0004410996
[0019]
That is, the compound (D) and the compound (E) were reacted in the presence of a base to obtain a compound (F). The obtained compound (F) is reacted with palladium-carbon in a hydrogen stream in the presence of an acid catalyst to simultaneously deprotect the Bn group and the Boc group, and then further reacted with a base to be deAc converted into a compound. (G) was obtained. Compound (G) and compound (H) were condensed with a condensing agent to obtain α-S-GalCer.
[0020]
Pharmacological test example 1: Action on systemic lupus erythematosus model animal MRL lpr / lpr mouse As a model of systemic lupus erythematosus, MRL lpr / lpr mouse is used as an index of lymph swelling and the preventive / therapeutic agent for autoimmune disease of the present invention The autoimmune disease inhibitory action of was evaluated.
Female MRL lpr / lpr mice were used as 10 per group. From 11 weeks of age, α-C-GalCer or α-S-GalCer is dissolved in a solvent (saline containing 10% dimethyl sulfoxide and 40% polyethylene glycol # 400), and the rate is 100 μg / kg body weight. It was administered intraperitoneally twice a week (Tuesday and Friday) for 21 days. In addition, the same amount of the above solvent was administered to the control. After the start of administration, the axillary lymph nodes were palpated twice a week and the progression of lymphadenopathy was observed over time. The degree of lymph node swelling was evaluated by scoring in four stages of 0, 1, 2, and 3, and the total of the left and right axillary scores was shown as a lymphadenopathy index.
[0021]
The time course of the lymph swelling index of each group is shown in FIG. In the solvent administration group, lymph nodes swelled over time immediately after the start of administration. In the α-C-GalCer administration group and the α-S-GalCer administration group, swelling was suppressed as compared to the solvent administration group. From these results, it was found that α-C-GalCer and α-S-GalCer suppress MRL lpr / lpr lymphadenopathy. MRL lpr / lpr mice, which are autoimmune abnormal animals, are model animals of human systemic lupus erythematosus (Clin. Immunol., 28, 1558-, 1996), so α-C-GalCer and α-S-GalCer are It is considered effective in the treatment of systemic lupus erythematosus.
[0022]
Pharmacological test example 2: Effect on sodium dextran sulfate DSS-induced ulcerative colitis As a model of ulcerative colitis, a colitis model with 4% DSS drinking water was used, and survival rate and weight change were used as indices, and the self of the present invention. The inhibitory action of autoimmune diseases of preventive and therapeutic agents for immune diseases was evaluated.
CDF1 mice were used as 10 mice per group. From 6 weeks of age, DSS was dissolved in drinking water so as to be 4% (W / V) and allowed to drink freely. The intraperitoneal administration of the solvent or α-C-GalCer or α-S-GalCer used in the above pharmacological test example 1 at a rate of 100 μg / kg body weight twice a week from the day after starting to give the 4% DSS solution The survival rate up to 28 days later was observed.
[0023]
The time course of the survival rate of each group is shown in FIG. In the α-C-GalCer-administered group and the α-S-GalCer-administered group, a significant increase in survival time was observed compared to the untreated group. The dextran sulfate sodium-induced ulcerative colitis model is widely used as a model of human ulcerative colitis (Gastroenterology, 109, 1344-, 1995). Therefore, α-C-GalCer and α-S-GalCer are considered effective for the treatment of ulcerative colitis.
[0024]
Pharmacological test example 3: Effects on experimental autoimmune encephalomyelitis in mice as a model for multiple sclerosis As a model for multiple sclerosis, the survival rate and weight changes of experimental autoimmune encephalomyelitis model mice were used as indicators. Thus, the autoimmune disease suppressing action of the autoimmune disease preventive / therapeutic agent of the present invention was evaluated.
SJL mice (Japan SLC Co., Ltd.) were used as 10 mice per group. At 6 weeks of age, 200 µg myelin basic protein and Mycobacterium tuberculosisi H37Ra were added to incomplete Freund's adjuvant to make an emulsion, and immunized by subcutaneous injection on each day on day 0 and day 7. . In addition, 500 ng pertussis toxin was administered intraperitoneally on day 0 and day 2 to induce autoimmune encephalomyelitis in mice. Solvent or α-S-GalCer was intraperitoneally administered twice a week at a rate of 100 μg / kg body weight, and the degree of onset of each mouse was observed daily.
[0025]
In the solvent administration group, 4 out of 10 cases were observed, but in the α-S-GalCer treatment group, only 1 out of 10 cases developed. α-S-GalCer was found to suppress the development of experimental autoimmune encephalomyelitis in mice. This model is a model of human multiple sclerosis (Acadenic Press Inc., 1,1-, 1994). Therefore, it shows that it is effective in the treatment of multiple sclerosis.
[0026]
