1. AT2433-A1, AT2433-A2, AT2433-B1 and AT2433-B2 novel antitumor compounds produced by Actinomadura melliaura. II. Structure determination
J Golik, T W Doyle, B Krishnan, G Dubay, J A Matson J Antibiot (Tokyo). 1989 Dec;42(12):1784-9. doi: 10.7164/antibiotics.42.1784.
The chemical structures of AT2433-A1 (2), AT2433-A2 (3), AT2433-B1 (4) and AT2433-B2 (5) were elucidated by degradation and spectroscopic studies. Compounds 2-5 are disaccharides closely related to rebeccamycin. The aglycone in 2 and 3 was determined to be 6-N-methyl-11-chloro-5H-indolo[2,3-a]pyrolo[3,4-c]carbazole and in 4 and 5 it was determined to be 6-N-methyl-5H-indolo[2,3-a]pyrolo[3,4-c]carbazole. Compounds 2 and 4 are 4-N"-methyl analogs of 3 and 5.

Compounds AT2433-A1 (A1), AT2433-A2 (A2), AT2433-B1 (B1), and AT2433-B2 (B2) were isolated from the cultured broth of Actinomadura melliaura sp. nov. (SCC 1655). Structurally these materials are closely related to rebeccamycin (1), an indolocarbazole antitumor antibiotic. A1, A2, B1, and B2 were active against Staphylococcus aureus A9537, Streptococcus faecalis A20688, Streptococcus faecium (ATCC 9790), Micrococcus lutea (ATCC 9341), Bacillus subtilis (ATCC 6633). A1 and B1 were active against P388 leukemia in mice.
