An antitumour isolate from the culture filtrate of the f-41 variant of streptomyces carzinostaticus. It is a protein of known amino acid sequence with a molecular weight of approximately 11,500 and possessing a regulatory function on the metabolism of DNA. In this process, that is first an inhibition of DNA biosynthesis followed by the degradation of DNA, zinostatin functions in a manner analogous to that of the much higher molecular weight antibiotic mitomycin c. Zinostatin is also a potent cytostatic agent active against gram-positive organisms.
