General description

Chemical structure: coumarin-glycoside

Application

Novobiocin is used to study heat shock protein inhibition and to produce positively supercoiled plasmid DNA. It is an inhibitor of bacterial DNA gyrase and eukaryotic DNA topoisomerase. It also is an inhibitor of retrovirus RNA-dependent DNA-polymerase.
For the production of positively supercoiled plasmid DNA. Inhibitor of bacterial DNA gyrase and eukaryotic DNA topoisomerase. Inhibitor of retrovirus RNA-dependent DNA-polymerase.

Biochem/physiol Actions

Novobiocin inhibits DNA synthesis by inhibiting bacterial DNA gyrase targeting the GyrB subunit of the enzyme involved in energy transduction. Novobiocin acts as a competitive inhibitors of the ATPase reaction catalysed by GyrB . It is also a Hsp90 inhibitor . Antimicrobial spectrum: Gram-positive bacterial.
Mode of Action: Inhibits DNA synthesis by inhibiting the enzyme Topoisomerase II.
Antimicrobial spectrum: Gram-positive bacterial.

Negative supercoiling of bacterial DNA by DNA gyrase influences all metabolic processes involving DNA and is essential for replication. Gyrase supercoils DNA by a mechanism called sign inversion, whereby a positive supercoil is directly inverted to a negative one by

Multi-drug-resistant infections caused by Gram-negative pathogens are rapidly increasing, highlighting the need for new chemotherapies. Unlike Gram-positive bacteria, where many different chemical classes of antibiotics show efficacy, Gram-negatives are intrinsically insensitive to many antimicrobials including the macrolides, rifamycins, and aminocoumarins
