ペプチド
実験において、ペプチドPXL01 (SEQ ID NO:56)を使用した。
塩化ナトリウム溶液に溶解したPXL01を、2.5% ヒアルロン酸ナトリウム溶液に、2/5 PXL01溶液および3/5 ヒアルロン酸ナトリウム溶液の体積比で加え、1.5% ヒアルロン酸ナトリウム中の1.5または6 mg/ml PXL01を得た。混合物を直径2.1 mmの針を通して何度か引っ張って下ろす(draw)ことにより、溶液をホモジナイズした。
PXL01の濃度およびヒアルロン酸ナトリウムにおける均一性は、UV検出器を有する高速液体クロマトグラフィー (Agilent model 1100) を用いて、220 nmにおいて決定した。使用した分析カラムは、Vydac 218TP (C18, 5 μm, 250 × 4.6 mm)であった。使用した移動相(1% アセトニトリルを含む水中の0.1% TFA (溶媒 A) およびアセトニトリル中の0.1% TFA (溶媒 B))を、勾配をつけて、流速1.0 ml/minで流した。希釈したPXL01標準を適用し、検量線を作成した。
0.25 mlの配合生成物を、組織培養プレート(24-Flat Well Tissue Culture Plate, Techno Plastic Products AG)のウェルに入れ、約1.3 mmの薄膜とした。プレートをサーモスタット (37℃) に1時間入れ、生成物の温度を37℃にした。37℃で再平衡化した0.5 mlの放出媒質 (PBS, pH 7.4)を用いて、ゲルの表面上に慎重に層を作製し、組織培養プレートを恒温振とう器(60 rpm, 37℃)に移した。予め決められた時間間隔で、10 μl アリコートの水溶液を、放出媒質から取り出した。放出されたPXL01の濃度を、分光光度的な測定を用いて、230 nmの波長でモニターした。230 nmにおける吸収の測定は、ペプチドならびに放出媒質中に溶解したヒアルロン酸ナトリウムを検出することができるため、いずれのPXL01も含まない同量のヒアルロン酸ナトリウムを有する対照の放出媒質を使用して、薬物を含むヒアルロン酸ナトリウムと比較した。
雌のSD系ラット (200-250g, Charles River Laboratories, Sulzfeldt, Germany) を、12時間の明暗サイクルに供し、実験動物の保護のための規制に従って世話をした。実験は、地域の倫理委員会から事前に承認を受けた後に行った。
雌のSD系ラット (200-250 g, Charles River Laboratories, Sulzfeldt, Germany) を、12時間の明暗サイクルに供し、実験動物の保護のための規制に従って世話をした。実験は、地域の倫理委員会から事前に承認を受けた後に行った。麻酔は、イソフルラン(Isoba(登録商標)vet, Shering-Plough Animal Health, Farum, Denmark)で行い、ラットは、手術後の鎮痛剤としてブプレノルフィン (48 μg/kg; Temgesic, Shering-Plough, Brussels)の筋肉内注射を受け、手術の前にビモトリム(Bimotrim)(80 mg/kg; Bimeda, UK,)の皮下注射を受けた。
ヒアルロン酸ナトリウム中のPXL01の放出挙動
塩化ナトリウム溶液に溶解したPXL01をヒアルロン酸ナトリウム溶液と混合することにより、均一なPXL01含有ヒドロゲルを得た。インビトロ放出実験は、ヒアルロン酸ナトリウムゲル製剤からのPXL01の突発的な放出を明らかにし、1時間以内に約70%のPXL01が放出された(図1)。初期の破裂により特徴づけられる放出挙動は、ヒアルロン酸ナトリウム中に配合された他の可溶性化合物についても既に示されている(Sherwood et al. 1992. Controlled antibody delivery systems. Biotechnology (N Y) 10, 1446-1449)。これは、薬物送達の間の初期の用量を提供し、遅延期間を最小化するために機能的に使用され得る。重要なことは、3つの独立した状況で調製された配合生成物からのPXL01の放出プロフィールの大部分が重複していることであり、これは、PXL01が負荷されたヒアルロン酸ナトリウムゲルの調製が再現性に優れていることを意味する(図1)。
側壁を欠損した盲腸擦過ラットモデル(上述したArnold et al.)を使用して、PXL01の抗癒着効果を明らかにした。このモデルは、処置されない場合に2つの傷害された表面の間に確実且つ安定した癒着を生じ、対照群のラットの85%が、直接の盲腸−腹膜壁の癒着を生じた(図2A)。3 mgのPXL01を含む水溶液を手術に関連して単一用量で投与した場合、癒着形成における有意な減少は観察されなかった(図2A−D)。しかしながら、1 mgのPXL01を含む水溶液を3回投与して動物を処置した場合、対照群のラットと比較して、癒着形成が著しく減少した(図2A、C)。これらの結果は、手術領域におけるPXL01のゆっくりとした放出が、ペプチド水溶液で1回だけ処置した場合と比較して有益であることを示す。
