Abstract: The present invention relates to new heterocyclic compounds containing nitrogen atoms or pharmaceutically acceptable salts thereof, a process for the preparation thereof, and a pharmaceutical composition comprising the same for treatment of cancer. The compounds according to the present invention induce DNA damage due to reactive oxygen species to activate c-abl and p53, induce RhoB to generate apoptosis, and induce cell death by down-regulating Bcl2 involved in cell survival, which is generated by dysregulated signals via the mitochondria pathway, thereby inhibiting tumor cell growth and inducing apoptosis. Accordingly, the composition according to the present invention can be used to treat cancer.
