In the course of a study of 6-N-amino-substituted analogues of NB-506 (1), a more potent anticancer drag, J-109,404 (2), in which the formyl group of NB-506 was replaced with a 1,3-dihydroxypropane group, was reported. A study of further modification in the positions of two hydroxyl groups at the indole rings of 2 resulted in the discovery of a 2,10-dihydroxy analogue, J- 107,088 (3), which is a promising anticancer agent with a broader therapeutic window than J-109,404.

A novel method for the synthesis of N-glycosylated dissymmetric indolo[2,3-a]pyrrolo-[3,4-c]carbazole derivatives was developed by applying the Mitsunobu reaction to the N-glycosylation reaction of substituted indole substrates.
