Application

Carbadox has been used to suppress aldosterone production, to study the spread of shiga toxin-producing Escherichia coli (STEC) strains, and to compare different antimicrobial activities.

Biochem/physiol Actions

Carbadox is a quinoxaline-di-N-oxide antibiotic that is generally used in feed to swine to prevent dysentery and improve feed efficiency. It inhibits bacteria by intercalation and induction of mutations in bacterial genome.

Quinoxaline-1,4-dioxides (QdNOs) are the potent heterocyclic N-oxides with interesting biological properties such as antibacterial, anticandida, antitubercular, anticancer and antiprotozoal activities. Here, we tested and compared the mequindox (MEQ) for mutagenic abilities in a battery of different short term tests according
