Synthesis and biological evaluation of novel benzodioxinocarbazoles (BDCZs) as potential anticancer agents.

We report the efficient synthesis and biological evaluation of new benzodioxinoindolocarbazoles heterocycles (BDCZs) designed as potential anticancer agents. Indolic substitution and maleimide variations were performed to design a new library of BDCZs and their cytotoxicity were evaluated on two representative cancer cell lines. Several derivatives have shown a marked cytotoxicity with IC(50) values in the nanomolar range. Results are reported in this Letter.
