Novobiocin, also known as albamycin, is an aminocoumarin antibiotic that is produced by the actinomycete Streptomyces niveus, which has recently been identified as a subjective synonym for S. spheroides [1] a member of the class Actinomycetia.

2005年6月13日 · Novobiocin is an antibiotic compound derived from Streptomyces niveus. It has a chemical structure similar to coumarin. Novobiocin binds to DNA gyrase and blocks adenosine triphosphatase (ATPase) activity.

Novobiocin is an orally active antibiotic that inhibits DNA gyrase by binding the ATP-binding site in the ATPase subunit. Although effective against Gram-positive pathogens, novobiocin has limited activity against Gram-negative organisms due to the ...

Novobiocin is a coumarin -derived antibiotic obtained from Streptomyces niveus. It has a role as an antibacterial agent, an EC 5.99.1.3 [DNA topoisomerase (ATP -hydrolysing)] inhibitor, an antimicrobial agent, an Escherichia coli metabolite and a hepatoprotective agent.

2021年7月27日 · The antibiotic novobiocin showed promise as a treatment for cancers with BRCA mutations that have become resistant to PARP inhibitors. It will soon be tested in NCI-supported clinical trials. The drug inhibits a protein called Pol theta.

Novobiocin is an antimicrobial drug that is structurally related to the coumarins. It is active against Gram-positive bacteria, such as Staphylococcus aureus (including meticillin-resistant strains) and other staphylococci; the enterococci are usually resistant.
