Patent ID: 7816388

Claim:
A compound of formula (I): where: A is CH 2 or CO; B is H, CHO or COOH; with the proviso that: when A is CH 2 , Q is a —(CH 2 ) n — group, in which n is an integer from 4 to 12, in which case R is absent; when A is CO, Q is selected from the group consisting of —(CH 2 ) a —CH(R—)—(CH 2 ) b —, where a and b are, independently, integers from 0 to n−1 and R is defined as below; W is a C 1 -C 12 alkylene or C 2 -C 12 alkenylene linear chain or a functionalized polyethylene glycol; or a C 6 -C 10 aromatic residue; or a glycofuranose residue; or W, alone or together with the nitrogen atom supporting the —(CH 2 ) c —NHR′ and —(CH 2 ) d —NHR″ chains, is a heterocyclic group with 5 or 6 members containing one or more heteroatoms selected from O, N, S; when W is an aromatic residue, an heterocyclic group or a sugar moiety, the nitrogen atom supporting the —(CH 2 ) c —NHR′ and —(CH 2 ) d —NHR″ chains is optionally absent and the —(CH 2 ) c —NHR′ and —(CH 2 ) d —NHR″ chains are directly and independently bonded to the carbon or nitrogen atoms of the aromatic and heterocyclic rings or to oxygen atoms of the glycofuranose residue; c and d independently are integers from 3 to 10; R′ and R″ are, independently, −Λ, where −Λ is a formula (II) macrocycle: where Y are the same or different and are selected from the group consisting of hydrogen, straight or branched C 1 -C 4 alkyl, —(CH 2 ) m —COOH, where m is an integer from 1 to 3; X is hydrogen, or the —CH 2 —U group, where U is selected from methyl, ethyl, p-aminophenyl, or X is the —(CHJ) 0 -Z group, where o is an integer from 1 to 5, J is hydrogen, methyl or ethyl, Z is a heterocyclic group with 5 or 6 members containing one or more heteroatoms selected from O, N—R 1 , R 1 being a hydrogen atom or a linear or branched C 1 -C 4 alkyl group, and S; or Z is selected from —NH 2 , —NH—C(═NH—)—NH 2 , or —S—R 2 where R 2 is a linear or branched C 1 -C 4 alkyl group; p is the integer 2 or 3; R is selected from the group consisting of linear or branched C 1 -C 4 alkyl, cycloalkyl, heterocycle or —(CH 2 ) q -T, where T is selected from the group consisting of S—CH 3 , —OH, or —COOH, and q is 0, 1 or 2.
