Description
シランカップリング剤において有機材料と反応する官能基は種々開発されているが、有機化合物の分野で最も代表的な官能基であるヒドロキシ基やカルボキシ基を持つシランカップリング剤の合成は難しく、従来、Sagivらが報告したように、薬品による化学反応による変換によりこれら官能基を導入する手法が考えられている(非特許文献1)。
このようなバイオセンサーチップの開発において、ガラスなどの基板にタンパク質を固定化する際に、その架橋剤としてシランカップリング剤が使用される。
これら両方の特徴をあわせ持つようなカップリング剤が合成されれば、生体分子のパターニングが可能となり、
表面に固定化した生体分子を光照射により脱離、回収することが可能となる。
また、マレイミドを含むシランカップリング剤は、マレイミド化合物がチオール分子と塩基を必要とせずに中性条件で反応し、しかもその反応が速いことから、バイオセンサーチップとして有用である。
さらに、親水性連鎖と疎水性連鎖からなる両親媒性ブロックコポリマーは、その親水性連鎖、疎水性連鎖の組み合わせや調整する溶液によって、低分子の両親媒性物質と同様に様々な会合状態を形成することが知られており、この両親媒性ブロックコポリマーでベシクル構造が形成されることが知られて以来、低分子ベシクルに比較した高分子ベシクル(ポリマーソーム、polymersome)についてさまざまな研究がなされている。このポリマーソームは内部に空孔を有するナノカプセルであり、高分子ミセルと同様に薬物送達用キャリヤーとしての利用が期待できる。
表面に固定化した生体分子を光照射により脱離、回収することが可能となる。
また、連結部(スペーサ)に光分解性基を有しているので、表面に固定化した生体分子を光照射により容易に脱離、回収することが可能になる。
このようなカップリング剤は、マレイミド基がチオール分子と塩基を必要とせずに中性条件で反応し、しかもその反応が速いことから、図2に示されるように、無機材料表面に修飾した直後にチオール分子の固定が可能であり、その後、光照射によって切り離し回収が可能である。
修飾したシリコンウェハとガラス基板を使い、光照射後、化学修飾を行い、親水性と疎水性でのパターニング、蛍光試薬を用いたパターニングを行った。チオールを含む蛍光色素は販売されていないので、マレイミドをcysteamine によって末端をアミノ基に変換し、その後、活性エステルを含む蛍光色素と反応させパターンを蛍光顕微鏡によって観察した。
また、前記ステップ1〜3によって得られた4−ヒドロキシ−5−メトキシ−2−ニトロアセトフェノンを用い、100 mL二口ナスフラスコに4−ヒドロキシ−5−メトキシ−2−ニトロアセトフェノン 3.80 g ( 18.0 mmol )、乾燥-DMF 25 mL、ポタシウムカルボネート 4.98 g ( 36.0 mmol )を加え懸濁させた後に、1,2−ジブロモメタン13.5 g ( 72.0 mmol )を加え窒素雰囲気下70 ℃で終夜撹拌した。これに水 50 mLを加え、エチルアセテート 50 mL ( 3 times )で抽出した。これをsat.NaCl aq 100 mL ( 5 times )で洗浄した後に、無水 MgSO4で乾燥した。これを濃縮し、カラムクロマトグラフィー( ヘキサン : エチルアセテート = 2 : 1 )で精製し濃縮後、真空乾燥をして白色固体の目的物(4−(2−ブロモ)エチル−5− メトキシ−2−ニトロアセトフェノン)を3.06 g得た(化33:ステップ21)。
