Abstract
The invention relates to novel chemical compounds which have useful antibacterial properties and are also of value in promoting animal growth and improving animal feed efficiency. More specifically, these new chemical compounds are certain sulfonylhydrazones of 1,4-dioxoquinoxaline-2-carboxaldehyde, 4-oxoquinoxaline-2-carboxaldehyde and certain derivatives thereof of formula (I): ##STR1## wherein A is N or N .fwdarw. O; R is a member selected from the group consisting of alkyl having from one to five carbon atoms, trifluoromethyl, phenyl, npahthyl, benzyl, styryl and phenyl substituted by up to two members selected from the group consisting of Cl, F, Br, CH.sub.3, CH.sub.3 O and NO.sub.2 ; R.sup.1 is hydrogen or methyl; R.sup.2 is hydrogen or methyl; R.sup.3 is a 6- or 7-position substituent and is selected from the group H, Cl, CH.sub.3, CH.sub.3 O, SO.sub.2 NH.sub.2, SO.sub.2 NHCH.sub.3 and SO.sub.2 N(CH.sub.3).sub.2 ; R.sup.4 is a 7- or 6-position substituent and is selected from the group H, Cl and CH.sub.3 ; with the proviso that when R.sup.4 is Cl or CH.sub.3, R.sup.3 and R.sup.4 are the same.
