1. A compound of formula (I) below:in which:
n, o and p, independently of each other, are integers ranging from 0 to 4; A1 represents a function —COOR1 in which R1 is a hydrogen atom or an alkali metal cation; or a group A2; A2 represents a group —P(O)(OCH2CH3)(OR2) or —P(O)(OR2)2 in which R2 represents a hydrogen atom or an alkali metal cation; each of the groups Y1 and Y2 represents a hydrogen atom or alternatively Y1 and Y2 together form a diradical forming one or more aromatic or heteroaromatic rings with the two carbon atoms that bear them, said aromatic rings optionally bearing one or more substituents chosen from a hydrogen atom, an amino group and a thiol group, X represents a bond segment having a group selected from the groups consisting of an amide function —C(O)—NH— and a triple bond —C≡C—; Z is:
NH2, a halogen, a phosphate,a group COOR3 in which R3 is H, an alkali metal cation, a quaternary ammonium group N(R4)4′ in which R4 is H or a linear alkyl chain preferably containing from 1 to 4 carbon atoms, a succinimide group —N—(CO—CH2—CH2—CO)— or a pentafluorophenyl group —C6F5;a biotin function (—CO—(CH2)4—C5H7N2OS), a polyheteroaromatic group or a crown ether,an organic or mineral silyl cluster;a macroscopic support. |
