MedKoo CAT#: 100755

CAS#: 801-52-5

Description: Porfiromycin is a n N-methyl derivative of the antineoplastic antibiotic mitomycin C isolated from the bacterium Streptomyces ardus and other Streptomyces bacterial species. Bioreduced porfiromycin generates oxygen radicals and alkylates DNA, producing interstrand cross-links and single-strand breaks, thereby inhibiting DNA synthesis. Porfiromycin is preferentially toxic to hypoxic cells.
