ことにより、相異なる性質を有する二つの層からなる多孔質ポリマー粒子を二相系中で製造することを含んでなる方法である。
図1は、粒子の表面にあるアリル基の酸化のために使用される、本発明に係る二相系の略図である。さらに具体的には、トルエンからなる第一の内部相及び酸化された表面を有するアリル化粒子が、Dextran(商標)T500(Amersham Biosciences AB、スウェーデン国ウプサラ)、KMnO4、NaOH及びH2O2からなる水性相中に示されている。
以下、実施例によって本発明を説明しよう。しかし、これらの実施例はもっぱら例示目的のために示すものであり、特許請求の範囲で定義される本発明を限定するものと解すべきでない。本明細書中の下記及びその他の箇所に示すすべての参考文献の開示内容は、援用によって本明細書の内容の一部をなす。
典型的な合成法では、機械攪拌機を備えた1L三つ口丸底フラスコに、NaOH水溶液(50%)(200g)、NaBH4(0.2g)及びNa2SO4(8g)を添加した。Streamline(商標)A300(Amersham Biosciences AB、スウェーデン国ウプサラ)ゲル(200g)を蒸留水で洗い、ガラスフィルター上で水切りした。続いて、撹拌下でビーズを三つ口丸底フラスコに添加し、反応混合物を50℃まで加熱し、この温度で撹拌を1時間続けた。次いで、アリルグリシジルエーテル(AGE)(300mL)を反応混合物に添加し、撹拌を50℃で18時間続けた。次いで、反応混合物を室温に冷却し、濃酢酸の添加でpH6〜7にした。次いで、ゲルをガラスフィルター上で濾過し、順次に蒸留水(5*200mL)、EtOH(99.5%)(5*200mL)、最後に蒸留水(5*200mL)で洗った。まず1mLのアリル化ビーズを臭素と反応させ、次いで得られたビーズを硝酸銀で滴定することにより、アリル含有量を測定した。一般に、アリル含有量は200〜250μmol/mLゲルの範囲内にあった。
アリル化したStreamline(商標)A300(Amersham Biosciences AB、スウェーデン国ウプサラ)(50mL)を、ガラスフィルター上でまずEtOH(99.5%)(4*50mL)で洗い、次いでトルエン(99%)(4*50mL)で洗った。最後のトルエン洗いでは、ビーズから部分的に液分を除去した。蒸留水(100mL)及びDextran T500(Amersham Biosciences AB、スウェーデン国ウプサラ)溶液(水中10%、100mL)を1L三つ口丸底フラスコに添加した。溶液に機械撹拌を施した。部分的に液分を除去したゲルをフラスコに添加し、蒸留水(50mL)及びDextran T500溶液(水中10%、50mL)をフラスコに添加した。溶液中における粒子の均質懸濁液を得、撹拌を15分間続けた。連続撹拌下で、過マンガン酸カリウム(KMnO4)(0.81g、5.12mmol、初期アリル基に対して0.5eq)をフラスコに添加した。反応混合物は紫色になり、反応を15分間進行させた。次いで、NaOH(水中50%、20mL)をフラスコに添加すると同時に、反応混合物は褐色になり、二酸化マンガン凝集体の生成を表した。反応を室温で1時間進行させた。次いで、pHが5に等しくなるまで、濃酢酸(約10mL)を混合物に添加した。H2O2水溶液(水中30%)(2mL)を混合物に注意深く添加したところ、混合物は灰色になった。次いで、ゲルをガラスフィルター上で濾過し、蒸留水(5*50mL)、EtOH(99.5%)(5*50mL)、最後に蒸留水(5*50mL)で洗った。実施例1に記載した手順に従ってアリル含有量を測定した。一般に、アリル含有量は初期アリル含有量に比べて5〜20%減少した。
部分酸化したStreamline(商標)A300(Amersham Biosciences AB、スウェーデン国ウプサラ)の残留アリル基の臭素化を以下のようにして行った。機械攪拌機を備えた250mL三つ口丸底フラスコ内で、酢酸ナトリウム(0.1g)を蒸留水(10mL)に溶解した。次いで、部分酸化ゲル(40mL、水切り済み)及び蒸留水(40mL)をフラスコに添加し、混合物を室温で15分間急速撹拌した。次いで、黄色が持続するようになるまで反応器に臭素を滴下した(約2mLのBr2)。撹拌を15分間続けた。次いで、黄色が消失するまでギ酸ナトリウムを添加した。続いて、ガラスフィルター上でゲルを蒸留水(5*50mL)で洗った。この臭素化ゲルを陰イオン交換体への誘導体化のために直接使用した(表1)。
実施例4−1:ジエチルアミン(ANX)のカップリング
様々なプロトタイプに関して細胞吸着測定を行った。結果を表2に報告する。結果は、様々なNaCl濃度における通過画分(FT)中及び溶離画分(E)中の細胞の百分率として示されている。REF.ANX及びREF.EDAとして示したゲルは、Streamline(商標)A300(Amersham Biosciences AB、スウェーデン国ウプサラ)のアリル化、臭素化、及び対応する陰イオン交換体のカップリングによる標準的な方法(即ち、原則として上述の通りであるが、外層の部分酸化を含まない方法)に従って製造したゲルに対応している。
