摘要: The specification describes novel antibiotic NCS-C and its free acid salts. Their antimicrobial effects are at least comparative with neocarzinostatin, and, against some microorganisms, superior. The novel antibiotic NCS-C or its free acid salt is prepared either by culturing an NCS-C yielding microorganism belonging to the Streptomyces family in a culture medium, separating the culture medium into bacterial bodies and culture filtrate, and extracting the culture filtrate with a water-immiscible polar organic solvent under acidic conditions, or by decomposing neocarzinostatin under acidic conditions and extracting resultant free acid salt with a polar organic solvent.

摘要: Neocarzinostatin derivatives having the formula; ##STR1## wherein N represents a neocarzinostatin residue, and R.sub.1 +R.sub.2 represents a residue of polystyrene-maleic acid copolymer having a molecular weight of 2,500 to 80,000. These neocarzinostatin derivatives are prepared by reacting neocarzinostatin with a polystyrene-maleic acid copolymer containing at least one maleic anhydride residue per molecule.The neocarzinostatin derivatives exhibit anticarcinogenic activity.
