Description
[化学式1]
[化学式2]
濃度が0.016w/v%である化合物4(NOCCL)のエタノール水溶液10μlおよび20w/v%アクリルアミド水溶液10μlを使用した以外は、すべての過程を実施例1と同様にし、ナノサイズのNORゲルナノ粒子を製造した。その粒度分布および走査型電子顕微鏡画像を図9に図示した。
1)ガス状の一酸化窒素に対する感応の実験
また、実施例1(NORゲル)および比較例1(CTLゲル)を一酸化窒素またはアルゴンガスに直接露出し、一酸化窒素反応性を評価した。
先ず、一酸化窒素溶液は既存に報告された方法にしたがって準備した。詳細には、40mlバイアルに蒸留水10mlを入れて窒素ガスで30分間バブリングした後、一酸化窒素装置に移した。一酸化窒素溶液をアルゴンガスで洗浄して酸素を除去した後、1.36atmの圧力で窒素ガスを30分間循環させた。飽和一酸化窒素溶液は、20℃で1.88mMの濃度を有するものと確認され、すべての一酸化窒素溶液は、実験の直前に新鮮にして準備した。
走査型電子顕微鏡(SEM、JSM 7410 F、JEOL社製)を使用して一酸化窒素溶液(1570μM)と反応させた前後に実施例1の形態を観察した。25℃で24時間一酸化窒素溶液と反応させた後、ゲルを−80℃で一晩中凍結乾燥し、断面を切り出し、白金(Pt)でコーティングした後、SEM画像を測定した。
一酸化窒素の影響を定量的に分析するために、レオロジーパラメータ、弾性係数(G´)および損失係数(G´´)を分析し、ヒドロゲルの粘弾性挙動を研究した。試験は、固定された温度、変形率および可変周波数の条件下で行われた。
NORゲルを一酸化窒素反応性薬物伝達プラットフォームとして適用することができるか調査するために、放出実験のためのモデルタンパク質としてFITC(fluorescein isothiocyanate)で標識されたBSA(bovine serum albumin)を使用した。詳細には、BSA(100μl、2mg/ml、in 4w/v%NaHCO3水溶液)をFITC(10μl、1mg/ml、in H2O)と混合して一晩中撹拌した。この溶液を水に対して、透析膜(MWCO3.5k)で透析を行い、未反応のFITCを除去した後、−80℃で凍結乾燥し、FITCで標識されたBSA(BSA‐FITC)を製造した。
体外で培養された細胞から分泌された一酸化窒素と反応することによるヒドロゲルの膨潤挙動を分析した。このために、RAW 264.7細胞およびNIH/3T3細胞を使用し、RAW 264.7細胞は、糖脂質(LPS、lipopolysaccharides)によって刺激される時に一酸化窒素を生成するラットマクロファージの1タイプであり、LPS処理をしなかったときには、約14μMの一酸化窒素が生成されるが、LPS処理をしたときには、約38μMの一酸化窒素が生成される。また、NIH/3T3細胞は、線維芽細胞であり、LPSに刺激されても一酸化窒素を生成しない細胞である。
