Abstract
A freshwater cyanobacterium, Nostoc spongiaeforme TISTR 8169, produced and excreted a novel violet pigment, nostocine A (1), which had broad -spectrum of growth inhibitory activity. The chemical structure of 1 w as determined as 6-methyl-1,3,6,7,8-pentaazabicyclo[4.3.0] nonan-1,3,5 (7)-trien-9-one on the bases of physicochemical evidence and an X-ray crystallographic analysis.
