Description
実施例1:mcの合成
m/z:309.2[M+H]+。1HNMR(400Mz,CDCl3):1~2(m,6H,CCH2CH2CH2C)、2.68(t,2H,CH2CO),2.95(s,4H,COCH2CH2CO)、3.68(t,2H,CH2N)、6.81(s,2H,CH=CH)。
FreestyleTM 293-F(Invitrogen)懸濁細胞を用いて2A1-HC-Cys254ins抗体を発現した。トランスフェクションの前日、6×105個/mLの密度で細胞を300mLのF17完全培地(FreestyleTM F17発現培地、Gibco社)を含む1L振盪フラスコに接種し、37℃、5%CO2、120rpmの条件下で細胞培養用シェーカーで一晩培養した。翌日にPEIで抗体発現プラスミドのトランスフェクションを行った(プラスミド:PEI=2:1)。トランスフェクションの翌日に、2.5%(v/v)でTN1フィード培地を加え、引き続き4日間培養した後、遠心分離し、上清を収集した。
この方法で得られた2A1-HC-Cys254ins抗体の濃度は2mg/mlであり、目的抗体モノマー(POI%)は90%を超えた。次の実験に用いた。
細胞で発現した2A1-HC-Cys357ins(配列番号:34)抗体をMabselect Sureにより精製し、低pHで溶離した直後、Tris溶液を加えて中和し、pH7.5のTris-HCl緩衝液に交換した。化合物mc-vc-PAB-MMAEは白色粉末であり、DMAに溶解して使用まで保存した。変異システイン残基上のマスキング基を除去するために、抗体を還元する必要がある。40倍の分子比で1MのDTT水溶液を2A1-HC-Cys357ins抗体溶液に加え、均一に混合した後、20℃で2時間反応させた。その後、サンプルのpHを5.0に調整し、SP Sepharose F.F.陽イオン交換クロマトグラフィーによりサンプル中のDTT及びマスキング基を除去した。その後、20倍の分子比でDHAA溶液をサンプルに加え、25℃で暗所で4時間反応させ、抗体鎖間ジスルフィド結合を再結合させた。そして、mc-vc-PAB-MMAE溶液を加え、mc-vc-PAB-MMAEと抗体変異システインを結合させ、均一に混合した後、25℃で2時間反応させた。反応終了後にSP Sepharose F.F.陽イオン交換クロマトグラフィーにより抗体分子に結合されていないmc-vc-PAB-MMAEを除去し、2A1-HC-Cys357ins-mc-vc-PAB-MMAE TDCサンプルを得た。
高速液体疎水クロマトグラフィー方法によりTDCサンプルを分析し、対応するピーク面積に基づいてDARを計算した。具体的な方法は以下の通りである。
カラム:Proteomix(登録商標)HICBu‐NP5(5μm,4.6x35mm)
移動相:A:2M硫酸アンモニウム,0.025M、pH7のリン酸緩衝液;B:0.025M、pH7のリン酸緩衝液;C:100%イソプロパノール
緩衝液Aで平衡化し、緩衝液Bと緩衝液Cでグラジエント溶離し、25℃、214nmで検出した。
TDC抗体骨格サンプルを37℃で保存し、0、7、14、21日目にそれぞれSEC-HPLCによりその凝集状況を分析した。具体的な方法は以下の通りである。
カラム:TSKgel SuperSW mAb HR(7.8mm×30cm)
移動相:0.1M硫酸ナトリウム;0.1M、pH6.7のリン酸緩衝液
25℃、280nmで検出した。
間接ELISA法により2A1-LC-Cys110ins-mc-vc-PAB-MMAE TDC、2A1-LC-Cys111ins-mc-vc-PAB-MMAE TDC、2A1-LC-Cys142ins-mc-vc-PAB-MMAE TDC和2A1-HC-Cys254ins-mc-vc-PAB-MMAE TDC、2A1-HC-Cys255ins-mc-vc-PAB-MMAE TDC、2A1-HC-Cys258ins-mc-vc-PAB-MMAE TDC、2A1-HC-Cys259ins-mc-vc-PAB-MMAE TDC、2A1-HC-Cys354ins-mc-vc-PAB-MMAE TDC、2A1-HC-Cys355ins-mc-vc-PAB-MMAE TDC、2A1-HC-Cys357ins-mc-vc-PAB-MMAE TDC、2A1-HC-Cys378ins-mc-vc-PAB-MMAE TDC、2A1-HC-Cys379ins-mc-vc-PAB-MMAE TDC、2A1-HC-Cys386ins-mc-vc-PAB-MMAE TDC、2A1-HC-Cys387ins-mc-vc-PAB-MMAE TDC、2A1-HC-Cys410ins-mc-vc-PAB-MMAE TDC及び2A1のEGFRvIIIに対する相対親和力を比較した。具体的な手順は以下の通りである。
表4:変異抗体の親和力の測定
以下の実験によりTDC細胞毒性活性を測定する。
TDCをEGFR過剰発現又はEGFRVIII発現のヒト腫瘍細胞培地に加え、細胞を72時間培養した後、細胞生存率を測定した。細胞のインビトロ実験により細胞生存率、細胞毒性及び本発明のTDC誘発性プログラム細胞死を測定した。
細胞増殖試験により抗体-毒素複合体のインビトロ薬効を測定した。CellTiter 96(登録商標)AqueousOne Solution Cell Proliferation Assayは市販品である(Promega Corp.,Madison,WI)。CellTiter 96(登録商標) AQueous One Solution Cell Proliferation Assay(a)は、比色法により細胞増殖及び細胞毒性実験における生細胞の数を測定する試薬である。この試薬は、新型のテトラゾール化合物[3-(4,5-dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfophenyl)-2H-tetrazolium,inner salt;MTS]及び電子カップリング剤(phenazine ethosulfate;PES)を含む。PESは、増強された化学安定性を有するため、MTSと混合して安定した溶液を形成することができる。このような便利な「単一溶液」の形態は、第一世代CellTiter 96(登録商標)AQueous Assayをもとに改良したものである。CellTiter 96(登録商標)AQueous Assayに用いる電子カップリング剤PMSとMTS溶液は別々に提供される。MTS(Owen's reagent)は、細胞により着色されたフォルマザン生成物に生物学的に還元され、そのまま培地に溶解することができる(図1)。この変換は、代謝が活発な細胞における脱水素酵素により生成したNADPH又はNADHの作用下で達成される可能性がある。検出の際に、少量のCellTiter 96(登録商標)AQueous One Solution Reagentを培養プレートウェルの培地にそのまま加え、1-4時間インキュベートした後、マイクロプレートリーダーで490nmでの吸光度値を読み取ればよい。
所定量のTDCサンプルをヒトIgGが除去されたヒト血漿に加え、各TDCについて3チューブずつ準備し、37℃の水浴でインキュベートし、それぞれ0時間、24時間、96時間インキュベートした後、TDCサンプルを取り出し、各チューブにProteinA(MabSelect SuReTM LX Lot:#10221479 GE、PBS洗浄済み)100ulを加え、縦型混合器で2時間振盪しながら吸着させ、洗浄、溶離した後、インキュベートされたTDCを得た。所定時間インキュベートされたTDCサンプルをHIC-HPLC及びRP-HPLCにより検出し、サンプルの血漿安定性を判定した。
表6:TDC血漿安定性の検出結果
ヒト膵臓腺がん細胞BxPC3のヌードマウス皮下移植腫瘍モデルを構築し、2A1-HC-Cys357ins-mc-vc-PAB-MMAE等のTDC結合薬物のインビボ薬効を評価した。5×106でA431細胞を4~6週齢のBALB/cヌードマウスの背中に皮下注射し、マウス腫瘍の平均サイズが約150~200mm3まで増殖した後、6匹/群でランダムに群分けした。1日目に、2A1-HC-Cys357ins-mc-vc-PAB-MMAE(2A1-HC-Cys357ins TDC)、2A1-HC-Cys410ins-mc-vc-PAB-MMAE(2A1-HC-Cys410ins TDC、2A1-HC-Cys387ins-mc-vc-PAB-MMAE(2A1-HC-Cys387insTDC)、2A1-HC-Cys378ins-mc-vc-PAB-MMAE(2A1-HC-Cys378insTDC)を5mg/kgの用量で尾静脈に単回投与した(図6)。テータは、測定時の腫瘍平均体積±SEを示す。
