Description
不安、鬱病、運動障害などの多くの中枢神経系疾患は、神経伝達物質5-ヒドロキシトリプトアミン(5-HT)またはセロトニンの乱れが関与していると考えられている。セロトニンは、中枢および末梢神経系に集中しており、およびとりわけ精神医学的障害、運動活動、摂食行動、性行動、および神経内分泌調節を含む多くのタイプの疾患に影響を及ぼすことが知られている。セロトニンの効果は、種々の5-HTレセプターサブタイプにより調節される。公知の5-HTレセプターには、5-HT1ファミリー(例えば、5−HT1A)、5-HT2ファミリー(例えば、5−HT2A)、5-HT3、5-HT4、5-HT5、5-HT6、および5-HT7サブタイプが含まれる。
5-HT6レセプターに関連するもしくはそれにより影響を受ける中枢神経系疾患の治療に有用な治療法および医薬組成物を提供することが、本発明のさらなる目的である。
本発明のこれらおよび他の目的および態様は、以下に示す詳細な記載により、より明らかとなろう。
本発明により、式:
Wは、SO2、CO、CONH、CSNHまたは(CH2)x;
Xは、O、SOnまたはNR11;
Yは、CR12またはN;
Zは、CR13またはN、ただし、YがNの時ZはCR13でなければならない;

の化合物またはその立体異性体または医薬上許容されるその塩が提供される。
本発明によりさらに、式Iの化合物の調製のための方法およびそれに有用な化合物が提供される。
5-ヒドロキシトリプトアミン−6(5−HT6)レセプターは、分子クローニングにより同定された最も新しいレセプターの一つである。精神医学に用いられる広範囲の治療化合物と結合するその能力は、脳におけるその固有の分布と合わせて、該レセプターと相互作用することができるもしくはそれに影響を及ぼすことができる新規化合物に関するかなりの関心を刺激した。現在、公知の完全に選択的なアゴニストは存在しない。精神医学、認識障害、運動機能および調節、記憶、気分などにおける5−HT6レセプターの潜在的な役割を理解するのにかなりの努力がなされている。この目的のために、5−TH6レセプターに対して結合アフィニティを示す化合物が、5−HT6レセプターの試験における補助として、および中枢神経系障害の治療における潜在的な治療薬として、強く求められている。

試験化合物の5−HT6結合アフィニティの比較評価
セロトニン5−HT6レセプターに対する試験化合物のアフィニティを以下の方法で評価する。ヒトクローン化5−HT6レセプターを発現している培養ヒーラー細胞を回収し、次いで低速(1,000×g)にて10.0分間遠心分離し、培養培地を除去する。回収した細胞を、半分の容積の新鮮な生理的リン酸緩衝塩水溶液中に懸濁し、次いで同じ速度で再度遠心分離する。この操作を反復する。回収した細胞を次いで10倍の50mMトリス.HCL(pH7.4)および0.5mMのEDTA中に均質化する。ホモジェネートを40,000×gにて30.0分間遠心分離し、次いで沈殿を回収する。得られたペレットを10倍量のトリス.HCLバッファーに再懸濁し、次いで同じスピードで再度遠心分離する。最終ペレットを少容積のトリス.HCLバッファーに懸濁し、次いで組織タンパク質含量を10−25μ1の容積の部分標本にて測定する。ウシ血清アルブミンを、1owry et a1., J. Bio1. Cheml93: 265 (1951)に記載されている方法に従いタンパク質の測定における基準として用いた。懸濁した細胞膜の体積を、1.0mg/mlの懸濁液の組織タンパク質濃度を得るべく調整する。調整した膜懸濁液(10倍の濃縮)を1.0ml容積に等分し、次いで−70℃にて、次なる結合実験に用いるまで貯蔵する。
Ki=IC50/(1+L/KD)
(ここで、Lは用いた放射能活性リガンドの濃度であり、およびKDは、レセプターに対するリガンドの解離定数である)に基き決定し、共にnMにて示す。
