9-Anilinoacridines substituted with a bromine atom in the 2-position of the anilino group or the 1-position of the acridine moiety can be cyclised with tributyltin hydride–AIBN to penta- or hexacyclic acridines. Of the polycyclic systems 13,14-dihydropyrrolo[3′,2′,1′:8,1]quino[4,3,2-kl]acridine 14a is the most potent cytotoxic agent displaying a mean GI50 concentration against a panel of 60 human tumour
The present invention relates to novel acridine derivatives of formula (I), or pharmaceutically acceptable salts thereof, which are inhibitors of the telomerase enzyme function. These compounds are useful for the treatment cellular proliferation disorders, such as cancer.
