Nocardamine is a ferrioxamine siderophore that has been found in Streptomyces and has diverse biological activities.1,2,3,4 It chelates iron in a chrome azurol S assay (IC50 = 9.9 µM).1 Nocardamine inhibits M. smegmatis and M. bovis biofilm formation (MIC = 10 µM for both), an effect that can be reversed by iron.2 It is cytotoxic to T47D, SK-MEL-5, SK-MEL-28, and RPMI-7951 cancer cells (IC50s = 6, 18, 12, and 14 µM, respectively).3 Nocardamine also induces morphological changes in BM-N4 insect cells.4
