Description
本願は、2008年1月24日に出願された米国仮特許出願第61/023,173号明細書に基づく優先権を主張する。本願は、その教示内容のすべてに対して、その全体が参照により本明細書に援用される。
(a)少なくとも1種のポリカチオン、少なくとも1種のポリアニオン、および少なくとも1種の多価カチオンを混合するステップを含み、ここで少なくとも1種のポリカチオンまたはポリアニオンは合成化合物であり、かつポリカチオンおよび/またはポリアニオンは、互いに架橋することが可能な少なくとも1つの基を含む、高分子電解質複合体を調製するステップと、
(b)高分子電解質複合体のpH、少なくとも1種の多価カチオンの濃度、またはこれらの組み合わせを調整し、接着複合コアセルベートを生成するステップと、
を含むプロセスによって生成されうる。
Pc3類似体。DOPA類似モノマー(ドーパミンメタクリルアミド、DMA)を、公開された手順を少し改良することで調製した(Lee B.P.、Huang K.、Nunalee FN.、Shull KR.、Messersmith PB. 「Synthesis of 3,4−dihydroxyphenylalanine(DOPA) containing monomers and their co−polymerization with PEG−diacrylate to form hydrogels.」 J Biomater Sci Polym編、2004年;15(4):449−464頁)。つまり、ホウ酸塩−ドーパミン複合体を、pH>9で塩化メタクリロイルと反応させた。酸性化によってホウ酸塩−カテコール結合を破壊した後、生成物を酢酸エチルで洗浄し、ヘキサンから再結晶化し、1H NMR(400MHz、DMSO−TMS):d8.8−8.58(2H,(OH)2−Ar−)、7.92(1H,−C(=O)−NH−)、6.64−6.57(2H,C6HH2(OH)2−)、6.42(1H,C6H2H(OH)2−)、5.61(1H,−C(=O)−C(−CH3)=CHH)、5.30(1H,−C(=O)−C(−CH3)=CHH)、3.21(2H,C6H3(OH)2−CH2−CH2(NH)−C(=O)−)、2.55(2H,C6H3(OH)2−CH2−CH2(NH)−C(=O)−)、1.84(3H,−C(=O)−C(−CH3)=CH2)によって検証した。
