FT671はユビキチン特異性のプロテアーゼ7(USP7)の有力で選択性の阻害剤であり、IC50値は52nMである[1]。USP7はMDM2を脱ユビキチン化でき、その結果、p53の細胞内レベルを減らした[2]。FT671は抗腫瘍活性を持つ[3]。
体外では、A549細胞をFT671 (0-24µM)で4時間事前処理した結果、細胞内SP1とβ-カテニンタンパク質の分解を著しく促進した[4]。FT671 (10µM)で大腸癌GCT116細胞を5分間処理した結果、USP7ノックダウンの条件下で、細胞内タンパク質のユビキチン化を著しく軽減した[5]。
体内では、FT671 (100, 200mg/kg)でMM.1S細胞異種移植マウスに経口投与した結果、マウスの腫瘍成長を用量依存的に著しく阻害し、忍耐性も良かった[6]。

| 細胞実験[1]: | |
細胞株 | A549細胞 |
準備方法 | A549細胞をFT671(0, 2, 4, 8, 16, 24µM)で4時間事前処理し、その後は50μg/mLのcycloheximide (CHX)で0-24時間処理し、ウエスタンブロット分析にタンパク質を使った。 |
反応条件 | 0, 2, 4, 8, 16, 24µM;4時間 |
アプリケーション | FT671は、A549癌細胞で、SP1とβ-カテニンの両方の分解を著しく促進した。 |
| 動物実験 [2]: | |
動物モデル | 非肥満性糖尿病重症複合免疫不全(NOD-SCID)マウス |
準備方法 | 6から8週齢の雌NOD SCIDマウスを、Co60照射源で照射(2Gγ)した。その24時間後に、RPMI-1640とMatrigelの1:1の混合で、5×106 MM.1S腫瘍細胞を皮下接種した。腫瘍が159mm3の平均体積に達した時、効率研究を始めた。腫瘍を負うマウスをランダムに処理群に分け、よって各処理群には同じ平均腫瘍体積になるようにした。マウスに、25mg/kgのFT671を導入投与し、その24時間後に、100または200mg/kgのFT671(一日に一回、経口投与)の投与を始めた。10% DMA/90% PEG400は溶媒対照物として使われた。処理群の間の腫瘍体積の差の統計分析について、繰り返された測定の2元ANOVAを実行し、その後、統計仮設テスト(Tukey)を使い、複数の比較の補正を行った。 |
投与形態 | 100, 200mg/kg/日;経口 |
アプリケーション | FT671でマウスを処理した結果、用量依存的に腫瘍成長を阻害した。高い用量でも、FT671は忍耐性が良く、実験中にこれと言った体重の減少も悪液質も観察されなかった。 |
