Blasticidin A is a high molecular weight tetramic acid isolated from S. resistomycificus in 1955.  It has broad-spectrum antifungal and antibacterial activity.  Like many tetramic acids, Blasticidin A is isolated as the stable calcium salt/complex. Blasticidin A and closely related Aflastatin A are specific inhibitors of the production of the aflatoxin produced  by the fungus Aspergillus parasiticus.

 Blasticidin A is soluble in DMF, DMSO and methanol and is moderately soluble in water and ethanol.
