New N-1,N-10 bridged pyrrolo[2,3-a]carbazole-3-carbaldehyde: synthesis and biological activities.
Résumé
The synthesis of new pyrrolocarbazoles substituted at N-1/N-10 positions is described. All the compounds tested demonstrated moderate to high Pim-1/Pim-3 kinase inhibitory potency. The most active inhibitors identified in this series (3, 17) have an alkyl chain bridging the N-1 and N-10 positions. These compounds (3, 17) exhibited apoptosis–inducing activity toward acute myeloid leukemia IPC-81 cells, but not toward normal fibroblasts.
