Abstract
[課題]本發明之課題為提供一種可使用於矽烷偶合劑之新穎有機矽化合物。[解決手段]解決課題之技術手段為提供一種下述式(1)：□(式中，A-表示為下述式(2)或式(3)：□，E表示為下述式(4)或式(5)：□，R1及R2各自獨立表示為碳原子數1至5之烷基，R3表示為氫原子或甲基，R4及R5各自獨立表示為碳原子數1至5之烷基，m、n及p各自獨立表示為1至5之整數，q表示為1至3之整數)所代表之有機矽化合物。
Description
本發明係關於藉由對矽、玻璃等之無機物質、或聚乙烯等之樹脂進行表面處理，可抑制蛋白質等之生物體物質、血小板等之細胞的附著，一分子內具有安定之正負雙電荷之甜菜鹼型或磺基甜菜鹼型有機矽化合物。
生物體系統與人工材料等外在物相接觸時，因為人體會將該人工材料認作為異物，伴隨時間經過而引起血栓形成、免疫反應、炎症反應等各種之異物反應。因此，使用人工臟器等之醫療用器具時，不得不併用如肝素等之抗凝血劑、免疫抑制劑之類的藥劑。
然而，使用上述抗凝血劑等的情況時，擔心會產生肝臟損害、過敏性反應等之各式各樣的副作用。
因此，為了解決這些問題，有提案使用在高分子鏈之側鏈上具有與生物體膜相同之兩性型磷脂之磷醯膽鹼之聚(2-甲基丙烯醯氧乙基磷醯膽鹼)(以下，在本說明書稱為MPC聚合物的醫療用材料(例如，參照專利文獻1及專利文獻2)。
又，有提案使用N-甲基丙烯醯氧乙基-N,N-二甲基銨-α-N-甲基羧基甜菜鹼之高分子量體(以下，在本說明書稱為CMB聚合物)之醫療用材料(例如，參照專利文獻3、專利文獻4及專利文獻5)。
藉由將MPC聚合物或CMB聚合物被覆於材料表面，即使不使用抗凝血劑的情況下亦可抑制血液凝固。

[專利文獻2]日本特開2000-279512號公報
[專利文獻3]日本特開2007-130194號公報
[專利文獻4]日本特開2008-274151號公報
[專利文獻5]日本特開2010-57745號公報
然而，從MPC聚合物及CMB聚合物之合成，進一步到製造含有該聚合物溶液之步驟有耗費時間的問題。本發明之課題，在於由製造溶液，可直接被覆於基材之表面上，然而可提供顯示與以往之MPC聚合物及CMB聚合物同等效果之非聚合物。
本發明者們，為解決上述課題，不附著蛋白質等之生物體物質、血小板等之細胞，發現於一分子內具有安定正負雙電荷之甜菜鹼型或磺基甜菜鹼型有機矽化合物。
亦即，本發明態樣之一種係如下述式(1)：
(式中，A-表示為下述式(2)或式(3)：
，E表示為下述式(4)或式(5)：
，前述式(4)及式(5)中之羰基表示為與鍵結R3之碳原子鍵結，R1及R2各自獨立表示為碳原子數1至5之烷基，R3表示為氫原子或甲基，R4及R5各自獨立表示為碳原子數1至5之烷基，m、n及p各自獨立表示為1至5之整數，q表示為1至3之整數)所代表之有機矽化合物。
本發明之其他態樣，係含有前述有機矽化合物、極性有機溶劑及水之矽烷偶合劑(表面處理劑)。
進而本發明之其他態樣，係由前述矽烷偶合劑所構成之生物體物質或細胞之黏著抑制劑。
又，本發明之其他態樣，係含有將前述矽烷偶合劑塗
佈於基材或將基材浸漬於該矽烷偶合劑中之步驟的矽烷偶合劑固定化方法。
藉由使用含有本發明之有機矽化合物之矽烷偶合劑(表面處理劑)，使矽、玻璃等之無機物質或聚乙烯等之樹脂(以下，在本說明書稱為基材)的表面處理變為可能，該表面被覆以一分子內具有安定之正負雙電荷之甜菜鹼或磺基甜菜鹼。因此，未使用如MPC聚合物、CMB聚合物之類的聚合物，蛋白質等之生物體物質、血小板等之細胞可不附著於上述無機物質或樹脂表面上。
前述式(1)所代表之有機矽化合物，例如可藉由使其與甜菜鹼及氫硫基矽烷反應而合成。
作為前述式(1)所代表之有機矽化合物之原料的甜菜鹼，例如以N-甲基丙烯醯氧乙基-N,N-二甲基銨-α-N-甲基羧基甜菜鹼、N-甲基丙烯醯氧乙基-N,N-二甲基銨-α-N-丙基亞碸基甜菜鹼、N-甲基丙烯醯基胺基丙基-N,N-二甲基銨-α-N-丙基亞碸基甜菜鹼為佳。
又，作為前述式(1)所代表之有機矽化合物之另一個原料的氫硫基矽烷，例如以3-氫硫基丙基三甲氧基矽烷、3-氫硫基丙基三乙氧基矽烷、3-氫硫基丙基甲基二甲氧基矽烷、(氫硫基甲基)二甲氧基矽烷、(氫硫基甲基
)二甲基乙氧基矽烷及氫硫基甲基三甲氧基矽烷為佳。
將上述有機矽化合物用於作為基材之無機物質的表面處理時，該無機物質並未特別限制。例如可列舉矽、銅、鐵、鋁、鎳或該等之合金、玻璃、二氧化矽、氧化鋁、氫氧化鋁、氧化鎂。
將上述有機矽化合物用於作為基材之樹脂的表面處理時，該樹脂並未特別限制。例如可列舉聚乙烯、聚丙烯、聚苯乙烯、聚氯乙烯、尼龍、聚胺基甲酸乙酯、聚脲、聚乳酸、聚乙醇酸、聚乙烯醇、聚乙酸乙烯酯、聚(甲基)丙烯酸、聚(甲基)丙烯酸衍生物、聚丙烯腈、聚(甲基)丙烯醯胺、聚(甲基)丙烯醯胺衍生物、聚碸、聚碳酸酯、纖維素、纖維素衍生物。
上述有機矽化合物，係可用於醫藥品、醫藥部外品、醫療用器具等之表面處理。作為前述醫療用器具之例子可列舉藥物傳送系統材料、成型輔助材料、包裝材、人工血管、血液透析膜、導管、保護線、隱形眼鏡、血液過濾器、儲血包、內視鏡、人工臟器、生物體晶片、細胞培養薄片、糖鏈合成機器，該醫療用器具並未特別限制。
