General description

Chemical structure: diphenyl ether derivative

Packaging

5, 25 g in poly bottle

Application

A component of cefsulodin-irgasan-novobiocin selection medium for Yersinia, a human pathogen that may contaminate animal-source food products. Because of its low antigenicity, irgasan is also a component of many antibacterial consumer products.

Biochem/physiol Actions

Irgasan is a broad spectrum antimicrobial agent. It is an inhibitor of the enoyl-ACP (acyl-carrier protein) reductase component of type II fatty acid synthase (FAS-II) in bacteria and Plasmodium. It also inhibits mammalian fatty acid synthase (FASN), and may have anticarcinogenic activity.

Other Notes
