Hitachimycin

Hitachimycin, also known as stubomycin, is a cyclic polypeptide produced by Streptomyces that acts as an antibiotic. It exhibits cytotoxic activity against mammalian cells, Gram-positive bacteria, yeast, and fungi, as well as hemolytic activity; this is mediated by changes at the cell membrane and subsequent lysis.[1] Owing to its cytotoxic activity against mammalian cells and tumors, it was first proposed as an antitumor antibiotic.[2]
