コンカナマイシンA(Concanamycin A)は、液胞型ATPアーゼ(V-ATPアーゼ)の特異的阻害剤であり、IC50値は10 nMである。
液胞型 ATPase(V-ATPase)は、男性の生殖能力に不可欠な精巣上体の内腔を酸性化するために明細胞によって発現される。さらに、細胞外培地へのプロトンの排出を誘導し、酸性の微小環境下で細胞内 pH を維持するのに寄与する。V-ATPaseは、固形腫瘍の周囲/内部の微小環境を酸性化するプロセスに関与し、いくつかの悪性腫瘍で腫瘍浸潤/多剤耐性を誘導することも報告されている。
コンカナマイシンA(CMA)は特異的なV-ATPase阻害剤であり、報告されているV-ATPase阻害剤SS33410とは異なる。口腔扁平上皮癌(OSCC)のOSCC細胞株(MISK81-5、SAS、HSC-4)では、低濃度のCMA処理により腫瘍細胞のアポトーシスが誘導された。大腸がん細胞株をコンカナマイシンAで前処理すると、V-ATPaseによるエンドソームの酸性化を阻害することで、腫瘍壊死因子(TNF)関連アポトーシス誘導リガンド(TRAIL)によるアポトーシスを有意に増強することができた。前立腺癌細胞株C4-2Bを用いて試験したところ、コンカナマイシンAによるV-ATPアーゼの阻害は、in vitroで80%の浸潤を減少させた。
コンカナマイシンAはまた、パーフォリンを介した細胞傷害経路を介したCTL細胞傷害性の強力な阻害剤としても報告されている。

細胞実験[1,2]: | |
細胞株 | HCT-116、DLD-1、Colo206F、HeLa細胞、アンドロゲン依存性細胞(LNCaP)およびアンドロゲン非依存性細胞(C4-2B) |
準備方法 | この化合物はDMSOに限定溶解する。高濃度を得るための一般的なヒント:チューブを37℃で10分間温めるか、超音波バスでしばらく振ってください。ストック液は-20℃以下で数ヶ月保存可能。 |
反応条件 | 20nM、60分 |
アプリケーション | CCAは、TRAIL感受性の大腸癌細胞株において、TRAILによるカスパーゼの活性化を効果的に抑制した。CCAで処理したColo206F細胞では、M30陽性アポトーシス細胞数が徐々に増加し、TRAIL添加後3~4時間で未処理細胞で見られた割合にほぼ達した。CCAで処理すると、TRAILで90分間インキュベートしたDLD-1細胞ではアポトーシスに関連したクロマチン凝縮が見られなかった。ナノモル濃度のコンカナマイシンAによる処理は、LNCaPおよびC4-2B細胞型におけるin vitro浸潤を80%減少させた。 その他の注意事項: すべての化合物の溶解度は屋内でテストしてください。実際の溶解度は理論値と若干異なる場合があります。これは実験システムのエラーによるもので、正常です。 |
