title: Synthesis and in vitro antitumor activity of 2-alkyl, 2-aryl, and 2-piperazinyl benzimidazole-4,7-dione derivatives.
abstract: A series of 2-alkyl, 2-aryl, and 2-piperazinyl benzimidazole-4,7-dione derivatives (7a-h) and 16m-o) were prepared, and their cytotoxicities were tested against three cancer cell lines (mouse lymphocytic leukemia cell line P388, and human gastric carcinoma cell lines SNU-1 and SNU-16). These compounds showed potent cytotoxicity against all of three cell lines tested, and especially SNU-16 was sensitive to them. 2-Aryl (7g,h) and 2-piperazinyl benzimidazole-4,7-dione derivative (16 m) were more potent than mitomycin C against P388 and SNU-16. Among benzimidazole-4,7-dione derivatives with alkyl group at position 2, 7a had the most potent cytotoxicity against all of the cell lines tested.
