Description

【0001】
【発明の属する技術分野】
本発明は、免疫抑制剤として有用なアミノジオール誘導体とその付加塩並びにその水和物に関する。
【0002】
【従来の技術】
【特許文献1】WO94/08943号パンフレット
【特許文献2】特開平9−2579602号公報
【特許文献3】WO02/06268号パンフレット
【特許文献4】特開平2002−53575号公報

免疫抑制剤は関節リウマチ、腎炎、変形性膝関節炎、全身性エリテマトーデス等の自己免疫疾患や炎症性腸疾患などの慢性炎症性疾患、喘息、皮膚炎などのアレルギー疾患の治療薬として多方面に利用されている。特に、医療技術の進歩に伴い、組織や臓器等の移植手術が数多く実施されるようになってきた近年の医療現場においては、移植後の拒絶反応をいかにうまくコントロールすることができるかが移植の成否を握っており、この領域においても免疫抑制剤は大変重要な役割を果たしている。
【0004】
臓器移植においては、アザチオプリンやミコフェノール酸モフェチルに代表される代謝拮抗剤、シクロスポリンAやタクロリムスに代表されるカルシニューリン阻害剤、プレドニゾロンに代表される副腎皮質ホルモン剤が用いられている。しかしながら、これらの薬剤は効果が不十分であったり、また腎障害などの重篤な副作用を回避するために薬物の血中濃度モニタリングが必須とされているものもあり、その効果や副作用の点で必ずしも満足のできるものではない。
【0005】
さらに、免疫抑制剤の副作用を軽減し十分な免疫抑制作用を得るために、作用機序の異なる複数の薬剤を使用する多剤併用療法が一般的であり、前述した免疫抑制剤とは異なる作用機序を持つ新しいタイプの薬剤の開発も望まれている。
【0006】
本発明者らはこのような課題を解決するために、アミノジオール誘導体に着目し、新しいタイプの免疫抑制剤の探索を行った。
【0007】
免疫抑制剤として、アミノジオール誘導体が
【特許文献1】、
【特許文献2】に開示されているが、本発明の特徴であるメタ位に置換基を有するベンゼン環とアミノジオール側鎖を有する芳香環とをスペーサーを介して連結させた誘導体が優れた免疫抑制効果を示すことは知られていなかった。また、
【特許文献3】、
【0008】
【特許文献4】、
【特許文献5】、
【特許文献6】に免疫抑制剤としてアミノモノアルコール誘導体が開示されているが、本出願化合物とは構造を異にするものである。
【0009】
【発明が解決しようとする課題】
本発明は、優れた免疫抑制作用を有し、かつ副作用の少ないアミノジオール誘導体を提供することにある。
【0010】
【課題を解決するための手段】
本発明者らは、代謝拮抗剤やカルシニューリン阻害剤とは作用機序を異にする免疫抑制剤について鋭意研究を重ねた結果、これまでに知られている免疫抑制剤とは構造を異にした新規なアミノジオール誘導体、特にメタ位に置換基を有するベンゼン環とアミノジオール側鎖を有する芳香環とをスペーサーを介して連結させた誘導体が強力な免疫抑制作用を有することを見出し、本発明を完成した。

[0003]
Immunosuppressants are widely used for the treatment of autoimmune diseases such as rheumatoid arthritis, nephritis, knee osteoarthritis, systemic lupus erythematosus, chronic inflammatory diseases such as inflammatory bowel disease, and allergic diseases such as asthma and dermatitis. Have been. In particular, in recent medical practice where transplantation of tissues and organs has been performed with the advancement of medical technology, how well rejection after transplantation can be controlled depends on how well transplantation can be controlled. We know the success and the immunosuppressants also play a very important role in this area.
[0004]
In organ transplantation, antimetabolites represented by azathioprine and mycophenolate mofetil, calcineurin inhibitors represented by cyclosporin A and tacrolimus, and corticosteroids represented by prednisolone are used. However, some of these drugs are inadequately effective, and some require monitoring of blood levels of the drug in order to avoid serious side effects such as renal impairment. Is not always satisfactory.
[0005]
Furthermore, in order to reduce the side effects of immunosuppressive drugs and obtain sufficient immunosuppressive action, multidrug combination therapy using multiple drugs with different mechanisms of action is common, and the effect differs from that of the aforementioned immunosuppressants. The development of new types of drugs with a mechanism is also desired.
[0006]
In order to solve such a problem, the present inventors focused on aminodiol derivatives and searched for a new type of immunosuppressant.
[0007]
Aminodiol derivatives as immunosuppressants
[Patent Document 1],
Although disclosed in Patent Document 2, a derivative obtained by linking a benzene ring having a substituent at the meta position and an aromatic ring having an aminodiol side chain via a spacer, which is a feature of the present invention, is excellent in immunity. It was not known to exhibit an inhibitory effect. Also,

[0009]
[Problems to be solved by the invention]
An object of the present invention is to provide an aminodiol derivative which has an excellent immunosuppressive action and has few side effects.
[0010]
[Means for Solving the Problems]
The present inventors have conducted intensive studies on immunosuppressive agents having a different mechanism of action from antimetabolites and calcineurin inhibitors, and as a result, they differed in structure from previously known immunosuppressants. The present inventors have found that novel aminodiol derivatives, particularly derivatives in which a benzene ring having a substituent at the meta-position and an aromatic ring having an aminodiol side chain are linked via a spacer have a strong immunosuppressive effect, and the present invention completed.

<Experimental example> Inhibitory effect of test compound on mouse host versus graft rejection
Transplantation, Vol. 55, No. 3, pp. 578-591, 1993. The procedure was carried out with reference to the method described in (1). Spleens were collected from BALB / c male mice 7-9 weeks old (Charles River Japan, Clea Japan, SLC Japan). The spleen is taken out in PBS (-) (Nissui Pharmaceutical) or RPMI-1640 medium (Gibco, Iwaki Glass), crushed with two slide glasses, and passed through a cell strainer (70 micron, Falcon) to give a spleen cell suspension. I made it. After removing the supernatant by centrifugation of the spleen cell suspension, ammonium chloride-tris isotonic buffer was added to lyse erythrocytes. After washing three times with RPMI-1640 medium by centrifugation, the cells were suspended in RPMI-1640 medium. To this was added mitomycin C (Kyowa Hakko) so that the final concentration was 25 μg / mL, and the mixture was added at 37 ° C. and 5% CO 2. 2 Incubated for 30 minutes under. After three times of centrifugal washing with RPMI-1640 medium, 2.5 × 10 8 Cells / mL, and this was used as a stimulating cell suspension. 20 μL of the stimulated cell suspension (5 × 10 6 Were injected subcutaneously into the right hind footpad of a C3H / HeN male mouse 7-9 weeks old (CLEA Japan, LLC) using a 27G needle and a microsyringe (Hamilton). The normal control group was injected with RPMI-1640 medium only. Four days later, the lymph node below the right knee was excised and weighed using a METTLER AT201 electronic balance (METTLER TOLEDO). The test compound was intraperitoneally administered once a day for a total of four times a day from the day of stimulator cell injection to three days later. The control group received a solvent having the same composition as that used for preparing the test compound. Table 7 shows the results.
