Description

General description

Chemical structure: diphenyl ether derivative

Application

A component of cefsulodin-irgasan-novobiocin selection medium for Yersinia, a human pathogen that may contaminate animal-source food products.

Biochem/physiol Actions

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.
