K. Irie et al., NEW TELEOCIDIN-RELATED METABOLITES, (-)-7-GERANYLINDOLACTAM-V AND BLASTMYCETIN-F, FROM STREPTOVERTICILLIUM-BLASTMYCETICUM, Journal of natural products, 57(3), 1994, pp. 363-368
Two new teleocidin-related metabolites, (-)-7-geranylindolactam-V [2]
and blastmycetin F [3], were isolated from fermentation broths of the
actinomycete Streptoverticillium blastmyceticum NA34-17, and their str
uctures were determined by spectroscopic methods. Compound 2 bound str
ongly to phorbol ester receptors in a mouse epidermal particulate frac
tion, suggesting that it is a potent in vivo rumor promoter comparable
to teleocidins A-1 [4] and B-4 [5].
