Abstract

The syntheses of a series of dipyrrolo [3, 4-a: 3, 4-c] carbazole-1, 3, 4, 6-tetraones, substituted in 10-position with saturated and unsaturated side chains, via palladium catalyzed cross-coupling reactions, are described. These compounds can be considered as granulatimide bis-imide analogues. Their inhibitory activity toward Chk1 kinase and their antiproliferative activities in vitro in four tumor cell lines are reported.
