シノビオリン蛋白質のユビキチン化活性阻害剤である。
シノビオリンは,E3ユビキチンリガーゼであり,自己ユビキチン化活性を有していることが知られている(国際公開第02/052007号パンフレット)。そこで,シノビオリンのインビボ(in vivo)での機能も自己ユビキチン化活性に依存していると考え,シノビオリンの自己ユビキチン化活性を阻害する物質を探索した。
MgCl2, 2mM ATP, 1 mM DTT, 0.1% NP−40, 800ng ubiquitin−FLAG, 15ng His−E1 (human), 250 ng E2 (His−UBE2G2), 100ng GST−SYNOΔTM, total 15μL)に任意の濃度の希釈系列で添加し,37度で60分間反応を行った。反応液中のタンパク質を7.5%SDS−PAGEで分離後,PVDF膜に転写し,抗FLAG抗体を用いてウエスタンブロットを行った。結果を表1及び図1に示す。なお,表1中の数値はユビキチン化活性のIC50値である。
関節リウマチ患者から得た滑膜細胞(RASC)を96 well plate に播種し,1日間培養したRASCの培養液中に任意の濃度の希釈系列で表1に記載された化合物を添加し,72時間後に細胞数をCell counting kit(WST-8)にて測定した。結果を表1に示す。なお,表1中の数値はRASCの増殖抑制活性のIC50値を示す。
3T3−L1細胞を10%FBS含有DMEM(High Glucose)でconfluentに達した後3日間培養した。500μM IBMX,1μM Dexamethasone,5 μg/mL Insulinを添加し分化を誘導した。同時に10μMのシノビオリンのユビキチン化活性阻害剤(表1に記載の各化合物)又は対照としてDMSOを添加した。3日間培養後,4μg/mL Insulinを含む培地に置換し10μMの前記各化合物又は対照としてDMSOを添加した。3日間培養後,DMEM(10%FBS,High Glucose)に置換し3日間培養した。
野生型マウス及び肥満モデルマウスを用いて,恒常的に高脂肪食を摂取させる条件下で本発明の化合物の投与がこれらのマウスの体重減少を誘導するか否かを検証した。
肥満モデルマウスとしては,代表的な肥満モデルマウスであるob/ob(レプチン遺伝子の異常)マウス,及びdb/db(レプチン受容体遺伝子の異常)マウス(いずれも中枢性に摂食が効かなくなり過食となり肥満,糖尿病,メタボリック症候群などのモデルとして汎用)を用いた。
また、前記試験において試験終了時のマウスを解剖し、脂肪組織の状態を観察した。348を投与した野生型マウスの写真を図3Cに示す。
