Description
以下、本発明の好ましい実施形態を記載する。下記の実施形態は本発明をより明確に表現するための目的として記載されるだけであり、本発明の内容が下記の実施形態に限定されるのではない。
下記の<数2>と表示されることにより、グリコールキトサンから本発明に従うグリコールキトサン誘導体を製造した。
グリコールキトサン、実施形態1乃至6のグリコールキトサン誘導体の蒸留水、DMSO、フォルムアマイド、DMF、メタノール、及びTHFに対する溶解度を確認した。
本発明に従うキトサン誘導体の生分解性は、ライソザイムの存在下に高分子溶液の粘度減少程度によって評価した。ライソザイムは人間の体液(血漿、唾、涙等)に多様に存在するため、種々の酵素の中で生分解挙動を評価するためにたくさん使われている。
自己集合したキトサン誘導体のナノ粒子の形態を走査電子顕微鏡(FESEM ; JSM-7000F ; JEOL、Japan)を用いて15kVで観察した。自己集合したキトサン誘導体を含む蒸留水1滴をシリコンウエーハの表面に置いて、4分の間20mAの金でスパッタリングしてコーティングした後、観察した。
本発明に従うキトサン誘導体のゾル−ゲル転移温度をテストチューブインバーティング(test tube inverting)法により確認した。
Claims (2)
- 下記の<化1>の構造を有し、アセチル化度は70乃至80%であることを特徴とする温度感応性グリコールキトサン誘導体:
(前記の<化1>で、上記nは10乃至10000の整数である。) - 請求項1のキトサン誘導体を含むことを特徴とする、薬物伝達体。
