Cathocin - General Information

An antibiotic compound derived from Streptomyces niveus. It has a chemical structure similar to coumarin. Cathocin binds to DNA gyrase, and blocks adenosine triphosphatase (ATPase) activity. (From Reynolds, Martindale The Extra Pharmacopoeia, 30th ed, p189) [PubChem]


Pharmacology of Cathocin

Cathocin is an aminocoumarin antibiotic that was produced by the actinomycete Streptomyces niveus. Cathocin binds to DNA gyrase, and blocks adenosine triphosphatase (ATPase) activity. Other antibiotics in the aminocoumarin class include coumermycin A1 and clorobiocin.


Additional information about Cathocin

Cathocin Indication: For the treatment of infections due to staphylococci and other susceptible organisms
Mechanism Of Action: Cathocin is an aminocoumarin. Aminocoumarins are very potent inhibitors of bacterial DNA gyrase and work by targeting the GyrB subunit of the enzyme involved in energy tranduction. Cathocin as well as the other aminocoumarin antibiotics act as competitive inhibitors of the ATPase reaction catalysed by GyrB.
