Disclosed herein are novel bifunctional compounds and their uses for the treatment and/or prophylaxis of cancers. The bifunctional compound disclosed herein has the structure of formula (I).
1,4-Bis(alkylamino)benzo[g]phthalazines able to form dinuclear complexes of Cu(II) which as free ligands behave as SOD inhibitors and show efficient in vitro activity against Trypanosoma cruzi
complexation. However, the substitution of nitrogen by oxygen in 3 leads to a tripodal dinuclear complex in which the sidechains are not involved. The in vitro antiparasitic activity on Trypanosoma cruzi epimastigotes and amastigotes and the SOD activity inhibition have been evaluated for compounds 1-3, and, as expected, 1 and 2 show in all cases relevant results, whereas 3 is always the less active

4-bis[(aminoalkyl)amino]-benzo[g]phthalazine-5,10-diones (BPDs) 1 which are related to the antitumor agents ametantrone and mitoxantrone. Derivatives 1 were prepared by chromic acid oxidation of acylated benzo[g]phthalazines 5 followed by acid hydrolysis or by silylation-amination of 5,10-dihydroxybenzo[g]phthalazine-1,4-dione (8). The 1-[(aminoalkyl)amino]-4-amino congeners 2 were isolated in low yields
Compounds of formula I are described, ##STR1## wherein: R.sub.1 and R.sub.2, that can be the same or different, are hydrogen or acyl groups; R.sub.3 and R.sub.4, that can be the same or different, are hydrogen or optionally substituted alkyl groups. The compounds of formula I are prepared by oxydation of the compounds of formula II: ##STR2## wherein the groups R'.sub.1, R'.sub.2, R'.sub.3 and R'.sub.4 have the same meanings as R.sub.1, R.sub.2, R.sub.3 and R.sub.4 or groups convertible to the latter. The compounds of formula I have remarkable antitumor activity.

The synthesis of new 1,4-bisalkylamino (2–4) and 1-alkylamino-4-chloro (5–6) substituted benzo[g]phthalazines is reported. Compounds 2–4 and 6 were prepared both in the free and heteroaromaticring protonated forms. Bifunctional 6 contains the 1,4-bisaminopropylpiperazine chain as a linker between the two heteroaromatic units, whereas 5 is its monofunctional analogue. The in vitro antitumour activity
