1. A series of N-acylsarcolysine hydrazides has been obtained by condensing N-acyl derivatives of sarcolysine with hydrazine hydrate in the presence of 1, 3-dicyclohexylcarbodiimide. 2. 1-(Sarcolysyl)-2-p-[di-(s-chloroethyl)amino]phenacetylhydrazine was obtained by the reduction of 1-(N-carbobenzoxysarcolysyl)-2-p-[p-(2-chloroethyl)amino]

Maleic Hydrazide and Isonicotinyl Hydrazide as Carbonyl Reagents
Physiologia Plantarum, 1966Abstract The effects of maleic hydrazide (MH) and isonicotinyl hydrazide (INH) on the reactions catalyzed by pea cotyledon amine oxidase, carrot root l‐glutamic decarboxylase, and wheat seedling transaminase have been studied. The activity of amine oxidase is inhibited if it is incubated with MH or INH before the addition of substrate, and it is also ...

Journal of Structural Chemistry, 2009
Results of studies performed under the guidance of A. E. Shvelashvili and continued after his decease are analyzed. We consider the coordination compounds containing both mono- and dihydrazides of carbonic acids; in particular, monohydrazides of monobasic benzoic and m-hydroxy benzoic acids (BH=C6H5C(O)NHNH2, m-HBH=HOC6H5C(O)NHNH2) and dihydrazides ...

Infrared Absorption Spectra of Hydrazides. II. Sodium Hydrazides
Bulletin of the Chemical Society of Japan, 1962Abstract The infrared absorption spectra of HCONH·NCOH· Na, CH3CONHNCOCH3· Na, CH3CON·HNCOC6H5· Na, and C6H5CONHNCOC6H5· Na and their N-deuterated derivatives have been examined in the rock salt region. The characteristic frequencies of the ions (RCON·HNCOR′)- have been obtained, and the influence of an electronic charge on the amide ...
