Abstract:

The hydrolysis of isatin aldazine4a–dafforded the unexpected 3,3′-(hydrazine-1,2-diylidene)bis(indolin-2-one) (5) and 1,2-di(arylidene)hydrazines6a–dthrough dual hydrolysis of4a–d. A mechanism to explain the formation of5and6a–dwas proposed. In addition, the hydrazinolysis of4a–dyielded 3-hydrazonoindolin-2-one (2) and 1,2-di(arylidene)hydrazines6a–dinstead of hydrazones17a–d, while hydrazinolysis of isatin ketazine5gave the expected 3-hydrazonoindolin-2-one (2). These results indicated the ability of the title compounds for unusual hydrolysis and hydrazinolysis reactions.

Abstract:

Background: N-phthalimide amino acid hydrazide is a class of compounds that have the potential therapeutic use. In general, hydrazinolysis of N-substituted amino acid(s) ester removes the ester group and yields the corresponding hydrazide. However, in case if N-substitution group is phthalimide, phthalimide group is cleaved and not the ester group. The resulted compound, therefore, is amino acid ester rather than Nphthalimide amino acid hydrazide. The above class of compounds, because of susceptibility of phthalimide group to hydrazinolysis, has previously been synthesized by a lengthy three-step procedure. Objective: N-phthaloylglycyl hydrazide was synthesized by using new efficient, simplified, one step process. Hydrazone derivatives from substituted benzaldehydes, and substituted furaldehyde were also synthesized. Method: N-phthaloylglycyl hydrazide was synthesized from the corresponding carboxylic acid using 1-Ethyl- 3-(3-dimethylaminopropyl)carbodiimide (EDC) as a coupling agent and hydroxybenzotriazole (HOBt) as an activator. Hydrazone derivatives were synthesized by condensation of N-phthaloylglycyl hydrazide with substituted benzaldehyde/substituted furaldehydes. All the compounds were characterized by IR, 1H-NMR, 13CNMR, mass spectroscopy and elemental analysis. Results: The presence of EDC/HOBt resulted in hydrazinolysis of the carboxylic acid group and not the phthalimide group. N-phthaloylglycyl hydrazide was synthesized in good yield. Conclusion: We report the improved process of the synthesis of N-phthaloylglycyl hydrazide. This is the first report where stability of phthaloyl amino acid compound to hydrazine is demonstrated. The reaction may be explored for the reaction schemes where stability of phthalimide group to hydrazinolysis is required.

Full text

Abstract:

The resilient of Methanothrix soehngenii strain FE was isolated. It contained carbohydrates (7%), mainly rhamnose, ribose, and fucose, which could be specifically liberated by alkaline hydrolysis or hydrazinolysis. Four oligosaccharide-containing fractions were separated; the two major fractions corresponded to large glycans composed of 15–30 residues. The whole sheath preparation was soluble in anhydrous hydrazine. A mild hydrazinolysis treatment led to a water-soluble glycoprotein fraction, which represented 60% of the starting material and contained 100% of the carbohydrates. These high molecular mass (> 500 kDa) glycoproteins were sensitive to pronase. Fast atom bombardment mass spectrometry analysis of the major glycopeptide fraction obtained after hydrogen fluoride treatment was in accordance with the presence of asparaginyl-rhamnose linkages on a Asn-X-Ser glycosylation site. This type of glycosidic linkage has been described previously in the surface layer of Bacillus stearothermophilus. Key words: Methanothrix soehngenii, Methanosaeta concilii, archaebacteria, bacterial glycoprotein, proteic sheath, asparaginyl-rhamnose.

Abstract:

Certain Biginelli pyrimidines with ester substitution in C5 were subjected to unexpected ring opening upon solvent-free reaction with hydrazine hydrate to give three products: pyrazole, arylidenehydrazines, and urea/thiourea, respectively. The nonisolable carbohydrazide intermediates are formed firstly followed by the intermolecular nucleophilic attack of terminal amino group of hydrazide function on sp2 C6 rather than the sp3 C4 to give the ring adduct which was produced as a final product.

Abstract:

In this work, the reaction of hydrazinolysis of higher fatty acid in the presence of an ionite catalyst is considered for the first time. Synthetic commodity anion exchange resin AB-17-8 was used as a catalyst. Before use, the anionite was converted to OH-form and its exchange capacity was determined. The experiments were made in the static conditions in a glass reactor with mixing of the reaction mixture.The reaction of palmitic acid with hydrazine yielded the corresponding hydrazide. The influence of various factors (quantity of hydrazine hydrate, catalyst, butyl alcohol, temperature, reaction duration) on the formation of palmitic acid hydrazide was studied. It is shown that with an increase in the amount of hydrazine hydrate in the initial mixture from 2.0 to 2.52 g per gram of palmitic acid, the yield of hydrazide increases, and further increase in the concentration of this reagent leads to a decrease in the selectivity of the process, due to the occurrence of side condensation reactions. Increasing the amount of catalyst from 2 to 3 g per gram of palmitic acid leads to an increase in the yield of hydrazide. It reveals optimum conditions of synthesis under which the most palmitic hydrazide yield made 90%. The analysis of the initial substances and the reaction product was carried out using the photocolorimetric method. As a result, the IR spectroscopic researches of the mechanism of hydrazinolysis reaction of the palmitic acid with active centers of anion-exchange. It is shown that the reaction proceeds with the formation of transition complexes on the surface of the anion exchange resin. The practical value of this work is to develop an effective method of palmitic acid hydrazide preparation. Keywords: palmitic acid, hydrazine, hydrazide, catalyst.

This work demonstrates that (N-acetyl[14C]glucosamine)2 is transferred from dolichyl pyrophosphate – (N-acetyl[14C]glucosamine)2 to endogenous nuclear glycoproteins. The (N-acetyl[l4C]gIucosamine)2 moiety is N-linked, since it can be released from the tryptic glycopeptides by N-glycosidase F and by hydrazinolysis, but not by β-elimination. The biological significance of this direct transfer of N, N′-diacetylchitobiose to nuclear proteins remains to be elucidated.Key words: nucleus, nuclear glycoproteins, nuclear N-acetylglucosaminyltransferase, N,N′ -diacetylchitobiose.

Abstract:

This paper describes the structures of the asparagine-linked oligosaccharides of two forms of guinea-pig Factor B of the alternative complement pathway with different Mr values. Oligosaccharides were quantitatively liberated from both glycoproteins by hydrazinolysis, fractionated by paper electrophoresis and Bio-Gel P-4 column chromatography, and their structures determined by sequential exoglycosidase digestions in conjunction with methylation analysis. Both glycoproteins were shown to have the same biantennary complex-type oligosaccharides but it is suggested that they contain different numbers of oligosaccharide chains.
