Abstract
Abstract Imines of 2-formylquinoxaline-3-carboxylic acid-1,4-dioxides and their salts are obtained through treatment of the lactone or a salt of 2-dihydroxymethylquinoxaline-N,N-dioxide-3-carboxylic acid with a reactant bearing a free primary amino group. The resultant compounds and their non-toxic salts are antibacterial agents and can be incorporated in pharmaceutical compositions and feedstuffs for this use. A typical embodiment is 2(carbomethoxyhydrazonomethyl)-quinoxaline-3-carboxylic acid-1,4dioxide.
