Bortezomib (PS-341)は抗腫瘍活性を備えたジペプチドボロン酸ポロテアソーム阻害剤としてスレオニン残基を標的とすることにより、0.6 nmのKiで20Sポロテアソームを強力に阻害できる[1]。
体外では、Bortezomibは細胞質にNF-kappabを保持し、22.5 nmのIC50値で細胞増殖を阻害できる[2]。BortezomibはIC50値が3.4-5.0 nmであるPEL(原発性滲出リンパ腫)の細胞株の成長を阻害でき、アポトーシスを誘発できる[3]。
体外では、1 µmol/l-10 nmol/lBortezomibはSRC-3の増加(ステロイド受容体子アクチベーター-3)を介してAkt経路を活性化できる[4]。体外では、20 nmのBortezomibはアポトーシスを誘発でき、G0/G1の期間停止を促進できる[5]。
体内ではBALB/c鼠を1 mg/kgのBortezomib腹腔内で1週間に1回二週間処理し、JNK(C-JUN N末端キナーゼ)および脊髄の細胞外シグナル調節プロテインキナーゼ(ERK)のリン酸化をぞうかさせる[6]。
体内では、鼠を毎週4週間、1日目と4日目にBortezomib(2 mg/kg,i.v.)で治療する。Bortezomibが処理した鼠は機械的な痛覚過敏の増強、尾神経伝導の減少および坐骨神経脱髄を示す[7]。

細胞実験[1]: | |
細胞株 | 骨髄(BM)細胞 |
準備方法 | 骨髄(BM)細胞におけるDCの増殖阻害分析を、それぞれ10 nm -50 nMBortezomibで24時間、48時間、72時間で処理する。 |
反応条件 | 10 nm -50 nm; 24時間、48時間72時間 |
アプリケーション | DCSの増殖は、コントロール細胞と比較して、10 nmのBortezomibで24時間治療する場合、有意に阻害される。この阻害は、Bortezomibの濃度が高いことで有意に増強される。未処理の細胞と比較して、40%未満の細胞が50 nmで24時間処理した場合に検出されました。BortezomibのDCSへの阻害は、用量依存と時間依存の両方である。 |
動物実験 [2]: | |
動物モデル | 6週齢のBALB/Cの雌アシミカルヌード鼠 |
準備方法 | HCS-2/8およびOUMS-27細胞をヌードBALB/C鼠の右脇の下に皮下注射した5日後、鼠をランダムに2つのグループに分割し、30日間、0.5 mg/kgの用量でDMSOまたはボテゾミブを腹腔内投与する。異種移植片の体積は、5日ごとに測定される(腫瘍体積=(長さ×幅2)/2)。 |
投与形態 | 0.5 mg/kg; S.C. |
アプリケーション | Bortezomibの投与は、治療の過程でin vivoでの腫瘍の成長を阻害するのに非常に効果的であり、腫瘍サイズの減少をもたらす。 |
