The present invention provides phosphoryl choline derivatives of general formula (I), which are suitable to be immobilized on a solid support to provide a separation material, which bind with both high affinity and high specificity to a protein, more specifically to C-reactive protein and anti-phosphoryl choline antibodies. Said separation materials are particularly useful in the extracorporeal removal of C-reactive protein and anti-phosphoryl choline antibodies from a biological fluid of a patient for prophylaxis and/or treatment of immune dysfunctions and cardiovascular diseases. Also claimed is a device containing a column that comprises separation material made from formula (I)
wherein
L is a linker as defined in the claims;
X is selected from: -SH, -NHR3, -C=CH, -CH=CH2, -N3, -CHO.
Also claimed is a separation material of general formula (II):
wherein
A is a solid support;
Y is a group obtainable from the reactive group X.
本发明提供了一般式(I)的磷酸胆碱衍生物,适合固定在固体支架上,以提供分离材料,其具有与蛋白质高亲和力和高特异性结合的能力,更具体地结合到C-反应蛋白和抗磷酸胆碱抗体。该分离材料在从患者的生物液中外体清除C-反应蛋白和抗磷酸胆碱抗体,以预防和/或治疗免疫功能障碍和心血管疾病方面特别有用。还声明了一种包含由公式(I)制成的分离材料的柱子的装置,其中L是如权利要求中定义的连接剂;X选自:-SH,-NHR3,-C = CH,-CH = CH2,-N3,-CHO。还声明了一种一般式(II)的分离材料:其中A是固体支架; Y是从反应基团X获得的基团。
