アミノ酸配列−(L)n−DMARD
[式中、アミノ酸配列はQKRAAYDQYGHAAFE−NH2(配列番号1)を含み、Lはリンカー単位であり、−は共有結合であり、nは0又は1である]を有する化合物を提供する。
式Iの化合物を製造するために、種々の合成スキームを計画することができる。化合物II及び化合物III〜Vの合成スキームを図1及び図2Aにそれぞれ示す。これらのスキームは、従来の固相合成、Boc保護HCQ又はp−ニトロ−フェノールエステルBoc保護HCQの調製、並びに従来の共役及び他の官能基の側鎖の脱保護等の後の、最終化合物の調製のためのこれらの使用を含む。これらの方法、又は所望により他の同様の合成プロセスを当業者が計画し、実行することができる。化合物V〜VIIIの合成スキームを、図2Bに示す。まず、リンカー1,4−ベンゼンジメタノールを1,1’−カルボニルジイミダゾール(CDI)によって活性化して、化合物2(1H−イミダゾール−1−カルボン酸、1,4フェニレンビス(メチレン)エステル Cas番号107845−94−3)を最初に得る。化合物2とHCQの縮合により、化合物3(4−((((2−((4−((7−クロロキノリン−4−イル)アミノ)ペンチル)(エチル)アミノ)エトキシ)カルボニル)オキシ)メチル)ベンジル1H−イミダゾール−1−カルボキシラート Cas番号未指定)を生成する。同時に、配列番号1(ペプチド)を、リジン、アスパラギン酸及びグルタミン酸のヒドラジンで除去可能な保護基を用いて調製する。化合物3と保護した配列番号1の反応により、共役した4が生じ、この複合体4を、脱保護ステップに供して最終複合体5を生成する。HCQのアミノ基及び/又はアルギニンのグアニジル基を保護/脱保護する追加ステップを、必要に応じて行って最終生成物を得る。化合物IX、X及びXIの合成は、化合物V〜VIIIの合成スキームと同様である。
これらの結果により、ヒト自己免疫疾患の治療のためのこの方法を、さらに発展させる機構原理を提供する。この試験はまた、インビボ及びインビトロで誘導性であり、免疫寛容の誘導を検出するにおいて、及び細胞免疫療法において有望なツールである、Tregのサブセットを同定する。
