research project on the synthesis of a number of pyrido[1,2-a]benzimidazolederivatives with possible antineoplastic activity, and as a result of the interesting antineoplastic activity recorded for one such compound (NSC 649900), somenew cycloalkylpyrido[1,2-a]benzimidazoles were prepared and evaluated for such activity. Compound (7c, NSC 682011) exhibited a good in vitro antineoplastic activity especially
