Porfiromycin

**Semantic type:** Amino Acid, Peptide, or Protein|Antibiotic|Pharmacologic Substance

**Definition:** An 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. (NCI04)
