.alpha.-Hydrazinocarboxamide and .alpha.-(.alpha.'-acylhydrazino)-carboxamide derivatives of formula I ##STR1## in which R.sup.1 and R.sup.2 each are lower alkyl or R.sup.1 and R.sup.2 together with the nitrogen atom to which they are joined form a piperidino or morpholino radical; R.sup.3 is hydrogen, lower alkanoyl, benzoyl, p-nitrobenzoyl, p-aminobenzoyl, p-chlorobenzoyl, isocyanoacetyl, or protected amino acyl radicals, for example, N-formylglycyl or ##STR2## (N-carbobenzoxyglycylglycyl); R.sup.4 is lower alkyl, CHR.sup.7 COOR.sup.8 or CH.sub.2 CH.sub.2 COOR.sup.8 wherein R.sup.7 is hydrogen or phenyl and R.sup.8 is hydrogen or lower alkyl; R.sup.5 is hydrogen or lower alkyl; or R.sup.4 and R.sup.5 together with the carbon atom to which they are joined form a cyclohexylidene radical; and R.sup.6 is a cyclohexyl or CHR.sup.9 COY wherein R.sup.9 is hydrogen or benzyl and Y is hydroxyl, lower alkoxy or amine, with the provisos that when Y is hydroxyl then R.sup.8 is hydrogen, that when Y is lower alkoxy than R.sup.8 is lower alkyl and that when Y is amino R.sup.4 is lower alkyl, are disclosed herein along with the related .alpha.-hydrazino-carboxamide and .alpha.-(.alpha.'-acylhydrazino)carboxamide compounds of formula III ##STR3## in which R.sup.1, R.sup.2, R.sup.3 , R.sup.5 and R.sup.7 are as defind above and Y is lower alkoxy. These compounds possess antibacterial activity. Methods for their preparation and use are disclosed also.
