Research Abstract

今年度に達成されたの主な具体的成果を箇条書きにした。
(1)分子プローブ設計グループ
神経突起伸展促進および細胞死抑制作用を示す新規エノン型プロスタグランジン(PG)の創製に成功した。これらの作用にはPGによるHO-1の誘導やJNKの活性化抑制が関与していることを明らかにした。核内受容体RXRヘテロダイマーのアンタゴニストHX531およびPA452を創製した。HX531はPPARγ-RXRの機能を阻害し、マウスにおいて抗糖尿病、抗肥満効果を示した。糖部をN型およびS型に強く束縛した新規核酸アナログを合成し、これらを組み込んだ修飾型オリゴヌクレオチドの創製に成功した。4'-チオリボヌクレオシドの立体選択的大量合成法を確立し、これらを組み込んだ4'-チオRNAオリゴマーの合成に成功した。生細胞可視化プローブに関して、フルオレスセイン類の構造と蛍光特性との関係を明らかにした。グルタミン酸トランスポーターブロッカーL-TBOAの構造を基に、グルタミン酸受容体作用が無く、より親和性の高い誘導体TFB-TBOAおよび光感受性のcaged-TBOAの創製に成功した。カップリング反応によるダントロレン誘導体の一般的合成法を確立し、生理的Ca^<2+>放出やCa^<2+>によるCa^<2+>放出機構に特異的に作用する探索分子の創製に成功した。
(2)分子機能解析グループ
ABCトランスポーター基質特異性解析のハイスループット化をめざし、ヒトP-糖タンパク質(ABCBl)の昆虫細胞での発現方法の確立と、96wellプレートを用いたATPase活性測定高速スクリーニング系の構築に成功した。これを用いて医薬品約50種をスクリーニングし、構造-輸送活性相関データベースを構築した。
(3)生体機能評価グループ
Shc、N-Shc、Sckのリン酸化チロシン受容ドメイン、SH2ドメインでのペプチドリガンドとの結合様式を分子モデリング手法を使って解析した。ベンゾチアゾール系化合物TG003がSRタンパク質リン酸化酵素のClk/StylおよびClk/Sty4を阻害することで選択的スプライシングのパターンに影響を与えることを見いだした。プロスタグランジンE受容体サブタイプEP3に共役するGタンパク質G12ファミリーに結合するエフェクター分子としてセリン・スレオニンホスファターゼPP5のクローニングに成功した。
(4)分子イメージンググループ
低酸素腫瘍に特異的に集積するPETトレーサーCu-ATSMの創製に成功した。[^<18>F]FDGと[^<64>Cu]ATSMを用いた担癌ウサギにおけるPET画像の比較から、両者に特徴的な集積が観測され、腫瘍画像診断における相補的検査手法となる可能性を示した。バイオラジオグラフィー法において時間解像度を改善するためPositron Emission Photon Imaging(PEPI)法を開発し、2分ごとの脳スライスイメージングを可能にした。
