title: Benzimidazole condensed ring systems 10 (1). Synthesis and cytotoxic activity of some pyrido[1,2-a]benzimidazoles.
abstract: As a part of research project on the synthesis of a number of pyrido[1,2-a]benzimidazole derivatives with possible antineoplastic activity and as a result of the interesting antineoplastic activity recorded for one such compounds (NSC 649900), some new pyrido[1,2-a]benzimidazoles were prepared and evaluated for such activity. Compound (11, NSC 660334) exhibited a moderate in vitro antineoplastic activity especially against most of the leukemia cell lines, while compound (10, VM30309) showed a good cytotoxic activity against Artina salina larvae (IC50 = 1.75 micrograms/ml).
