Bufotalinは天然の強心ステロイドであり、ヒキガエルの分泌液から由来する[1]。BufotalinはNa⁺/K⁺-ATPaseを阻害し、癌細胞のアポトーシスを誘発する[2]。Bufotalinは抗腫瘍と強心作用を持っている[3-4]。
R-HepG2細胞で、比較的に低い濃度のBufotalin (0.05μM, 0.125μM;24時間、48時間)の処理は、著しいG2/M停止を誘発した[5]。A375細胞で、Bufotalin (10-80ng/mL;24時間)は細胞の増殖を阻害した[6]。MDA-MB-231細胞で、Bufotalin (1-10μM;72時間)は用量依存的に細胞の増殖を阻害する[7]。
ブレオマイシン誘発の肺線維症マウスモデルで、Bufotalin (1mg/kg, 2mg/kg;腹腔内;7日間)は肺損傷、炎症と線維症を減らし、肺の機能を保護する[8]。シェーグレン症候群(ESS)マウスモデルで、Bufotalin (10μg/kg;静脈内;7週間、週に二回)はTh17分極、サイトカインIL-17とIFN-γの分泌を阻害する[9]。U251細胞異種移植を持つマウスで、Bufotalin (1mg/kg, 2mg/kg, 5mg/kg;腹腔内注射;14日間)の処理の結果、腫瘍の体積と重量を用量依存的に著しく減らした[10]。

| 細胞実験[1]: | |
細胞株 | R-HepG2細胞 |
準備方法 | Bufotalin処理後、R-HepG2細胞の細胞周期分布をフローサイトメトリーで検出した。手短に言えば、R-HepG2細胞(約6 × 105/ウェル)を採取し、4℃で70%のエタノールで一晩中固定した。分析の前に、細胞を2500rpmで3分間遠心分離し、エタノールを除去した。その後、37℃、暗所で、0.02mg/mL propidium iodide (PI)と0.1mg/mL Ribonuclease A (RNase A)を含有する500mLのリン酸緩衝の生理食塩水(PBS)で、細胞を30分間懸濁した。PI-DNA複合体からの蛍光をEpics XLフローサイトメトリーで測定した。 |
反応条件 | 0.05μM, 0.125μM;24時間、48時間 |
アプリケーション | 細胞周期分析の結果、R-HepG2細胞で、比較的に低い濃度のBufotalinの処理は、著しいG2/M停止を誘発した。 |
| 動物実験 [2]: | |
動物モデル | Bleomycin (BLM)誘発の肺線維症マウスモデル |
準備方法 | 雄のC57BL/6マウス(6週齢、平均体重は約22g)を、12時間の昼夜循環、22-25℃、40–60%の湿度で、水と飼料を自由に摂取させる標準環境で飼育した。BLM誘発の肺線維症モデルを行った。まず、計35匹のマウスをランダムに5つのグループに分けた:(i)模擬対照群;(ii)溶媒群;(iii) Bufotalin (1mg/kg)群;(iv) Bufotalin (2mg/kg)群;(v)陽性対照[pirfenidone (PFD, 30mg/kg)]群。その後、マウスに1%のpentobarbital sodium (50mg/kg)を腹腔内注射しマウスを麻酔し、50μLの無菌生理食塩水の中の3mg/kg BLMを気管内投与した。マウスには模擬対照群と同量の無菌生理食塩水を投与した。BLM投与後の7日目から、マウスにBufotalin、PFDまたは溶媒(15% PEG400と15% tween 80生理食塩水溶液)を14日間連続、毎日腹腔内注射した。最後に、マウスをBLMチャレンジの21日後に殺処分した。 |
投与形態 | 1mg/kg, 2mg/kg;腹腔内注射;7日間 |
アプリケーション | Bufotalinは肺損傷、炎症と線維症を減らし、肺の機能を保護する。 |
