Description	Novobiocin is an orally active and potent antibiotic.Novobiocin is a DNA gyrase inhibitor and heat shock protein 90 (Hsp90) antagonist with inhibitory effects on gyrase and Hsp90. Novobiocin has anti-positive activity and can be used to study highly resistant pneumococcal infections.
In vitro	Novobiocin (1 mM) competitively hinders the binding of ATP to gyrase B, disrupting nucleotide binding, and impairs the interaction between the co-chaperones Hsc70 and p23 with Hsp90.[1] Novobiocin (200 µM; 24 h) results in the inhibition of the repair rate of DNA interstrand cross-links induced by both cisplatin (cis-DDP) and BCNU. This is accompanied by a corresponding reduction in the clonogenic survival of human glioblastoma multiforme cells.[2] Novobiocin (0.3 mM; 48 hours) triggers caspase-3/7 enzyme-dependent apoptosis assays, resulting in an approximate three- to fivefold increase in the number of apoptotic cells in K562, HL60, and Mutz-2.[5]
In vivo	Novobiocin (25, 50, 100, 200 mg/kg; s.c.; 4 times at 1, 5, 24, and 48 h after infection; Adult female Swiss mice (30g) with sepsis induced by the penicillin-susceptible strain (AR33118)) shows anti-infection activity in mice infected with amoxicillin-resistant Streptococcus pneumoniae.[3]
