Synthesis and cytotoxic evaluation of N-1,N-m-bis[(tetrahydrobenzo[a]acridin-12-yl)phenyl]alkanediamides and N-1,N-m-bis[(tetrahydrobenzo[c]acridin-7-yl)phenyl]-alkanediamides

Abstract

The title compounds were synthesized in four steps from 5,5-dimethyl-1, 3-cyclohexanedione as starting material. These compounds were evaluated against 60 tumoral cell lines, whereas the N-I,N-m-bis[benzo[c]acridin-7-yl]phenyl] alkanediamides displaying significant cytotoxic activity, the corresponding N-I,N-m-bis[benzo[a]acridin-12-yl]phenyl]alkanediamides derivatives were found to be less cytotoxic.
