Patent ID: 7728000

Claim:
A compound of formula (I) G 1 -L-G 2 (I) or a pharmaceutically acceptable salt thereof, wherein: -G 1 is a radical (II) wherein —R′ is an electron pair or a (C 1 -C 3 )-alkyl radical; with the condition that (i) when —R′ is an electron pair, a is a N═C double bond and the fused ring is the biradical thus radical (II) is (IIa′), and (ii) when —R′ is a (C 1 -C 3 )-alkyl radical, a is a N—C single bond and the fused ring is the triradical thus radical (II) is (IIa″); wherein —R 1 to —R 12 represent radicals, same or different, selected from the group consisting of H, (C 1 -C 4 )-alkyl, (C 1 -C 4 )-alkoxy, (C 1 -C 4 )-alkylamino, phenyl, F, Cl, Br, amino, hydroxy, and nitro; and wherein —B— is a biradical selected from the group consisting of —CONH—, —NR 13 —, —O—, —(CH 2 ) n NH—, and —(CH 2 ) n O—; wherein —R 13 is selected from the group consisting of H, (C 1 -C 4 )-alkyl, (C 1 -C 4 )-alkoxy and (C 1 -C 4 )-alkylamino; and n is an integer from 1 to 3; -L- is a covalent linking biradical selected from the following ones; —(CH 2 ) r NR′″(CH 2 ) s — —(CH 2 ) r NR′″(CH 2 ) s NR″″(CH 2 ) t — wherein —R′″ and —R″″ are radicals, same or different, selected from the group consisting of H and (C 1 -C 3 )-alkyl; r is an integer from 1 to 3; s is an integer from 1 to 3; t is an integer from 1 to 3; and -G 2 is a radical selected from a radical of formula (II), the N-radical of 1,8-naphthalimide, the C4-radical of 2-phenylquinoline, and the C9-radical of acridine.
