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 of general formula (II), 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 provided is a column that comprises the separation material of general formula (II), as well as a device containing the column. Formula (I), wherein variable X is selected from: -SH, -NHR3, -C=CH, -CH=CH2, -N3and -CHO; the other variables are as defined in the claims: Formula (II), wherein variable "A" represents a solid support. "A" as well as the other variables are defined in detail in the claims.

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.
A novelpolyamine toxin, named MG30, was isolated from the venom of the spider, Macrothele gigas, and its structure was elucidated by two-dimensional NMR and mass analysis. In addition, the enantioselective synthesis of MG30 was achieved to assign its absolute stereochemistry.
