Outline of Annual Research Achievements

前々年度、および前年度、用いた各種天然化合物の中でグラブリジンが最も4量体安定化能を発揮し、昨年度はグラブリジン、および製品化されているグラボノイド(グラブリジンが主成分であるが、いつくかのポリフェノールが含有されているサプリメント)を用いて、in vivoにおける研究を主体に展開したところ以下の結果を得た。
1.[マウスを用いた検討]wild type マウスおよびトランスジェニックマウス(FAP ATTR Val30Met)にin vitroで最もTTR 安定化能が得られた化合物を投与し、 TTR 濃度の上昇および投与前後でTTRの安定化能を検証したところ、有意な4量体安定化能が確認できた。さらに、得られた血液から抗TTR 抗 体を用いてTTR-薬剤複合体を捕捉後、逆相HPLC を用いた測定により天然化合物がTTR に選択的に結合していることを明らかにした。
2.[ヒトを用いた検討]健常者に最も有望であったグラボノイド(グラブリジンよりグラボノイドが有用であった)を投与し、経時的に採血しTTR の血中濃度を測定し上昇しているか調べるとともに、Semi-denaturing Western blot でTTR 安定化能の変化を検証したところ、良好な安定化が得られることが判明した。さらに、得られた血液から抗TTR 抗体を用いてTTR-薬剤複合体を捕捉後、逆相HPLC を用いた測定により天然化合物がTTR に選択的に結合していることが明らかになった。
3.実験2においては投与期間中、および投与後、全くside effectは確認されなかった。以上の結果をもとに、循環器科と共同研究を行い、老人性全身性アミロイドーシス患者にグラボノイド投与を行い、アミロイドーシスの進展がどうなるか、現在プロトコールを作成中である。
