Outline of Annual Research Achievements |
糖尿病血管合併症の発症進展にはadvanced glycation end-products (AGE)とその膜型受容体receptor for AGE (RAGE)の相互作用が関わる。しかし、RAGEにはRNAスプライシングによって産生される内在性分泌型RAGE(endogenous secretory RAGE, esRAGE)も存在し、膜型RAGEも細胞外領域切断酵素(ectodomain sheddases)によって可溶型RAGE(soluble RAGE, sRAGE)になりうる。このような可溶型RAGEはデコイ受容体として病態の発症進展に抑制的に働く。従って、shedding機構を増強し、膜型RAGEを減らしsRAGE量を上昇させることは糖尿病血管合併症に対して抑制的に働くと考えられる。本研究ではRAGE shedding誘導の薬剤・化合物のスクリーニングをScreen-Well@FDA Approved Drug Library (2 mg/mL) BML-2841J Version 1.6Jを用いて行った。1次スクリーニングにおいて約640種類のうち102種類の薬剤・化合物に絞り込んだ。続いて、濃度依存性をみる2次スクリーニングにおいて46種類、さらにsRAGEの測定において最終的に6種類にまで絞りこむことができた。動物実験において、比較的短時間で効果が評価できる炎症性腸疾患モデルを用いて検証を行った結果、1つの化合物でsRAGE産生の亢進と膜型RAGE 発現の低下、炎症性サイトカイであるTNFaとMCP-1の低下、病理学的な炎症像の改善を認めた。
