The synthesis and cytotoxic activity studies of a new series of cyclic amine containing benzoxazole and benzoxazolone derivatives are described. The 2-cyclic amine-1,3-benzoxazoles 5a-k, 5-chloro-3-(3-chloropropyl)- 1,3-benzoxazol-2(3H)-one 8 and 3-[3-(cyclic amino)- propyl]-1,3-benzoxazol-2(3H) -ones 9a-f were synthesized. The newly synthesized compounds with the influence of the presence of cyclic amine moiety in the benzoxazole scaffold have been evaluated with respect to their cytotoxic effect toward four human cancer cell lines. The new compounds were evaluated to see whether substitution at the second and third position of the benzoxazole motif influence their cytotoxic effect toward cancer cells.
