.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.
.alpha.-Hydrazinocarboxamide和.alpha.-(.alpha.'-acylhydrazino)-carboxamide的衍生物具有以下结构式I的公式##STR1##其中R.sup.1和R.sup.2分别是较低的烷基或R.sup.1和R.sup.2与它们连接的氮原子形成吡啶基或吗啉基; R.sup.3是氢、较低的烷酰基、苯甲酰基、对硝基苯甲酰基、对氨基苯甲酰基、对氯苯甲酰基、异氰基乙酰基或保护的氨基酰基,例如,N-甲酰基甘氨酰基或##STR2##(N-羧苄氧甘氨酰甘氨酰基); R.sup.4是较低的烷基、CHR.sup.7 COOR.sup.8或CH.sub.2 CH.sub.2 COOR.sup.8,其中R.sup.7是氢或苯基,R.sup.8是氢或较低的烷基; R.sup.5是氢或较低的烷基;或R.sup.4和R.sup.5与它们连接的碳原子形成环己烯基; R.sup.6是环己基或CHR.sup.9 COY,其中R.sup.9是氢或苄基,Y是羟基、较低的烷氧基或胺基,但是如果Y是羟基,则R.sup.8是氢,如果Y是较低的烷氧基,则R.sup.8是较低的烷基,如果Y是氨基,则R.sup.4是较低的烷基。此外,还披露了与相关的α-水合肼基-羧酰胺和α-(α'-酰基水合肼基)羧酰胺化合物的公式III##STR3##其中R.sup.1、R.sup.2、R.sup.3、R.sup.5和R.sup.7如上所述,Y是较低的烷氧基。这些化合物具有抗菌活性。还公开了它们的制备和使用方法。
