Abstract:
A compound of formula (I): wherein:A is a polyfurictional substrate selected from the following; Z is a bile acid residue or a conjugate with taurine and glycine; Y1 and Y2, which can be the same or different, are selected from the following: residue a residue b residue c residue d residue e residue fL1, L2 and L3, which can be the same or different, are a single bond between the functional groups of Y1 and A, Y2 and A and/or Z and A, or a spacer chain with at most 20 carbon atoms; as well as a complex chelate thereof with the ions of metal elements having atomic numbers ranging between 20 and 31, 39, 42, 43, 44, 49, and between 57 and 83, and a salt thereof with an organic base selected from primary, secondary, tertiary amines or basic amino acids, or with an inorganic base the cations of which are sodium, potassium, magnesium, calciuiin or mixtures thereof, or with anions of physiologically acceptable organic or inorganic acids; wherein linking between A and Y1 and Y2 is between a functionalized amino group present on Y1 and Y2 and a carboxylic residue present on A or between a carboxylic residue of Y1 and Y2 and an amino residue of A to form an amide and wherein linking between A and the bile acid residue Z is by formation of an amido bond.
