The present invention relates to a compound of formula (IIa) of following general formulae:
in which:
R1, R2 and R3 represent, independently of one another, -COOH, -P(O)(OH)2 or -R6-P(O)-OH in which R6 represents an H atom or a C1-C3 alkyl group;
X1, X2 and X3 represent, independently of one another, L-Y in which L represents a C1-C3 alkyl group,
Y represents -NR7-CO-R8, in which R7 represents H or a C1-C6 alkyl group or a C1-C6 hydroxyalkyl group, and R8 represents a C1-C6 alkyl or C1-C6 hydroxyalkyl group, provided that at least R7 or R8 represents a C1-C6 hydroxyalkyl group;
D represents CH or N;
E represents CH or N;
F1 represents CH or N;
K1 to K12 each independently represent H, -(CH2)j-CH3 or -(CH2)i-OH, in which j = 0 to 3 and i = 1 to 3, or K3 or K4 with K5 or K6, and/or K7 or K8 with K9 or K10, form a ring having 3 to 6 carbon atoms;
or an isomer, an enantiomer or a diastereoisomer of these or their mixtures.
