Abstract

Compounds of the general formula (I): in which inter alia Q 1 represents —NR 1 R 3 , —OR 1 or —SR 1 and Q 2 represents —NR 2 R 4 , —OR 2 or —SR 2 , and A represents the point of attachment to a support matrix, are useful as protein binding ligands when (a) at least one of R 1 , R 2 , R 3 and R 4 includes an alkyl group —C n H 2n+1 in which n is greater than or equal to 7; (b) at least two of R 1 , R 2 , R 3 and R 4 independently include an alkyl group —C n H 2n+1 or a cycloalkyl group —C n H 2n−1 in which n is greater than or equal to 4; or (c) at least three of R 1 , R 2 , R 3 and R 4 independently include a C 1-12 alkyl group substituted by —NR 5 R 6 or aryl.

Claims (21)

1. A compound of the formula (I)

wherein

Q 1 represents —NR 1 R 3 ; and

Q 2 represents —NR 2 R 4 ;

in which

R 1 and R 2 which may be the same or different, independently represent

an alkyl group selected from the group consisting of hexyl, 1-methylpentyl, 2-methylpentyl, 3-methylpentyl, 4-methylpentyl, 2-ethylbutyl, 1,1-dimethylbutyl, 1,2-dimethylbutyl, 1, 3-dimethylbutyl, heptyl, 1,4-dimethylpentyl, 2,4-dimethylpentyl, octyl, nonyl, decyl, undecyl, and dodecyl;

R 3 and R 4 both represent methyl; and

A represents the point of attachment to a support matrix, optionally through a spacer linkage interposed between the matrix and the compound of formula (I).

2. A compound as claimed in claim 1 , which has the structure

3. A compound as claimed in claim 1 , which is attached at the point A to a support matrix in the form of optionally activated polysaccharide, agarose, cellulose, chitin, dextran, methacrylate, hydroxyalkylmethacrylate, styrenedivinylbenzene or polyvinylalcohol.

4. A method for the synthesis of a compound of formula (I), as defined in claim 1 , which method comprises:

reacting a compound of formula (II)

with an amine-containing support matrix to form the compound of formula (I), wherein Q 1 and Q 2 in the compound of formula (II) are as defined in claim 1 .

5. A method for the synthesis of a compound of formula (I), as defined in claim 1 , which method comprises:

reacting a compound of formula (XI)

with an amine-containing support matrix to form a compound of formula (XII)

reacting the compound of formula (XII) with a compound of formula H-Q 2 ;

wherein Q 1 , and A in the compounds of formulae (XI) and (XII) are as defined in claim 1 , and Q 2 in the compound of formula H-Q 2 is as defined in claim 1 .

6. A library of related compounds of formula (I), as defined in claim 1 , said compounds being attached via the point A to a common support matrix.

7. A process for the separation, purification or discovery of a proteinaceous material, which process comprises contacting a sample containing the proteinaceous material with a compound of formula (I), as defined in claim 1 .
