Resistoflavine is a rare, boat-shaped, pentacyclic polyketide isolated from several species of Streptomyces, often co-produced with resistomycin. Resistoflavine exhibits weak antibiacterial activity against Gram postive and Gram negative bacteria and exhibits potent cytotoxic activity against tumor cell lines in vitro. Resistoflavine inhibits growth, nucleic acid and protein synthesis in Bacillus subtilis.
