Porfiromycin

Porfiromycin, an N-methyl derivative of mitomycin C, is a bioreductive antibiotic that alkylates DNA and generates oxygen radicals, causing interstrand cross-links and single-strand breaks to inhibit DNA synthesis. Its selective toxicity toward hypoxic cells makes it a valuable tool for researching tumor hypoxia, DNA damage mechanisms, and combination therapies in both in vitro and in vivo cancer models.
