Porfiromycin is a n N-methyl analogue of the antineoplastic antibiotic mitomycin C extracted 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. References: Haffty BG, Wilson LD, Son YH, Cho EI, Papac RJ, Fischer DB, Rockwell S, Sartorelli AC, Ross DA, Sasaki CT, Fischer JJ.
