Description
Novobiocin is an aminocoumarin antibiotic that inhibits the ATPase activity of the B subunit of bacterial DNA gyrase. Novobiocin is most often used in the treatment of methicillin-resistant Staphylococcus aureus (MRSA) infections. In addition to its antibacterial activity, novobiocin also displays anticancer chemotherapeutic and anti-angiogenic properties. Novoboicin inhibits HIF-1α binding to transcriptional coactivator p300/CBP in tumor models and analogs of this compound are in development as HSP90 inhibitors.
