Description
自己免疫疾患の従来の治療法は、グルココルチコイドや免疫抑制剤といった"非特異的な免疫抑制療法"が主体である。"非特異的な免疫抑制療法"とは、免疫細胞の持つ多くの生物学的機能を、特に選定せずに、無差別に抑制するような治療法である。これらの治療法は、したがって、病気を誘導・増悪させるような生物反応を抑制すると同時に、生体に必要な反応をも抑制する(副作用)。そこで、より特異的な免疫抑制剤(病気を誘導・増悪させるような生物反応のみを抑制する薬剤)の開発が切望されてきた。近年、この目標にそって、自己抗原のペプチド療法が試みられたが、ペプチドは個々人によっても異なる、主要組織適合遺伝子複合体(MHC)分子によって提示されるために、個人ごとに効力の差が著しく、またアレルギー反応も問題になってくる。
R3は−CH2−、−CH(OH)−CH2−又は−CH=CH−を表すが、好ましくは−CH2−又は−CH(OH)−CH2−であり、最も好ましくは−CH(OH)−CH2−である。
R4は水素原子又はCH3を表すが、好ましくは水素原子である。
xは0〜35、好ましくは0〜26であり、より好ましくは11〜26、更に好ましくは11〜23、最も好ましくは18〜23である。
本発明の糖脂質は、IL−4が抑制的に働くような自己免疫疾患であれば、ただちにその治療薬として応用できる。また、IL−4は抗体産生を高める作用を持つので、ワクチン療法の補助剤として応用可能である。更に、肝炎ウイルスワクチンなどで、なかなか抗体価の上がらない患者に併用すると効果があると考えられる。更に、NKT細胞の機能低下を来すような疾患に応用できる。
NKT細胞は、a)抗腫瘍活性(腫瘍細胞殺傷効果)、b)IFN−γ産生、c)IL−4産生などの生理機能を発揮し、産生されたIFN−γによりd)NK細胞の活性増強やe)マクロファージ活性化が誘導される。すなわちa)b)c)はNKT細胞の直接作用、d)e)はb)を介して誘導される間接作用である。

上記の合成化合物の生物活性を以下の方法で評価した。
まず、合成糖脂質(化合物25及びα-GC(化合物36))を用いて、実験的自己免疫性脳脊髄炎(EAE)の抑制の検討を行った。
6−8週齢の雌C57BL6J(B6)マウスにミエリン・オリゴデンドロサイト糖蛋白(MOG)の35−55残基に相当するペプチド(配列番号1)100μgを結核死菌(H37Ra)を併用下にエマルジョンとして尾根部に免疫した。同日に百日咳毒素200ngを尾静脈より、48時間後に百日咳毒素200ngを経腹腔的に投与してEAEを誘導し、臨床症状を観察するとともに、病理学的検討を行った。合成糖脂質は、経口投与(400ng/kg)を行った。コントロールにはDMSO(ジメチルスルホキシド)のみ投与した。
その結果を表1に示す。評価には下記の臨床スコア及び病理スコアを用いた。
臨床スコア 0:正常、1:尾のトーヌス低下、2:尾の下垂・歩行不安定、3:中等度後肢脱力、4:後肢完全脱力、5:四肢麻痺、6:死亡
病理スコア 0:正常、1:軟膜・軟膜下細胞浸潤、2:中等度血管周囲細胞浸潤、3:高度血管周囲細胞浸潤、4:脳実質細胞浸潤
次に、上記自己免疫性脳脊髄炎(EAE)の抑制試験に記載の方法でEAEを誘導し、化合物25(100μg/kg)経腹腔投与によるEAE抑制効果を検討した。その結果を図3に示す。経腹腔投与でも経口投与と同様にEAE抑制効果がみられた。
次に、合成糖脂質(化合物25及びα−GC)及びDMSOを用いて、実験的自己免疫性能脊髄炎(EAE)の抑制の機序の検討を行った。
A)6−8週齢の雄C57BL6マウスにトリType IIコラーゲン100μgを結核死菌(H37Ra)を併用下にエマルジョンとして尾根部に免疫した。21日めに同様のエマルジョンを尾根部に追加免疫し、臨床症状を観察した。合成糖脂質は、追加免疫時から週2回経腹腔投与(500μg/kg)を行った。コントロールはDMSOのみ投与した。
臨床スコア 0:症状なし、1:四肢の指など小関節が1本のみ腫脹発赤、2:小関節2本以上、あるいは手首や足首などの比較的大きな関節が腫脹発赤、3:1本の手や足全体が腫脹発赤、4:1本の手や足の全体的腫脹が最大限に達していると判断したとき、とし、両手、両足の合計を点数とする。
B6マウスにおけるコラーゲン関節炎において化合物25投与で、疾患抑制効果がみられた。
症状出現後のコラーゲン関節炎において化合物25の投与で、疾患抑制効果がみられた。
従来の報告通り、α−GC投与ではINF−γとが優位に産生されるが、化合物25投与ではIL−4が優位に産生されることがわかった。
