hydrazide การใช้

• Also the amide analogs exhibited higher affinity than hydrazide analogs.
• A related hydrazide auxiliary can also be used for similar DABCO-catalyzed MBH reaction.
• The carbonyl group is probed using typically hydrazide-or alkoxy amine-functionalized dyes or other compounds.
• A related species is the monoformyl analog, called formic hydrazide ( HCON 2 H 3, ).
• 21 analogs possessing either an alkyl amide or an alkyl hydrazide of variant lengths in position 3 were synthesized.
• All analogs except the carboxylic acid and hydrazide analogs were derivatized from isolated bottromycin A2 using an activated azide ester.
• The compound consists of a 1, 2, 4-triazole heterocycle with three functional groups : amine, thioamide, hydrazide.
• "' Biotin hydrazide "'is a biotinyl derivative that can be used as a probe for the determination of protein carbonylation.
• It was shown that the percentage of chromosomal aberrations induced by maleic hydrazide ( 0.01 % ) declined significantly with 24-epibrassinolide treatment.
• The general structure for a hydrazide is E ( = O )-NR-NR 2, where the R's are frequently hydrogens.
• Azide has been used traditionally as an MPO inhibitor, but 4-aminobenzoic acid hydrazide ( 4-ABH ) is a more specific inhibitor of MPO.
• Correa ( Rutaceae ), was further evaluated for the antigenotoxicity against maleic hydrazide ( MH )-induced genotoxicity in " Allium cepa " chromosomal aberration assay.
• Isoniazid ( isonicotinic acid hydrazide ), ethionamide, triclosan [ 5-chloro-2-( 2, 4-dichlorophenoxy )-phenol ] and TLM are known to specifically inhibit mycolic acid biosynthesis.
• After 4 hours at 110 癈, the indole ring structure has been broken into ( 2-amino-5-fluoro-phenyl )-acetic acid hydrazide with reduction of the ketone at the 3-position.
• Benard " et al " ( 2004 ) synthesized INIs with a quinoline subunit and an ancillary aromatic ring linked by functionalized spacers such as amide, hydrazide, urea and hydroxyprop-1-en-3-one moiety.
• Since there already is an array of aldehyde-speci
  鹀 reagents commercially available ( such as aminooxy or hydrazide reagents ), possible applications are diverse and include the conjugation of fluorophores, glycans, PEG ( polyethylene glycol ) chains or reactive groups for further synthesis ( see applications ).
• The aforementioned conversion to acyl azide has been carried out multifariously; Bergmann utilized methyl ester and hydrazide, whereas more recent attempts have designed methods such as : nitrosylation of N-formylaminoacyl hydrazide and subsequent substitution by sodium azide, and reaction between TMS azide and the anhydride of an amino acid.

• Mycobacterium ulcerans ", IS2404 and IS2606, were detected by PCR . These isolates could be differentiated from other slowly growing pigmented mycobacteria by their inability to grow at 37 癈, production of niacin and urease, absence of nitrate reductase, negative Tween 80 hydrolysis and resistance to isoniazid ( 1 礸 ml 1 ), p-nitrobenzoic acid, thiacetazone and thiophene-2-carboxylic hydrazide.
• Another active area are studies of electroreduction and electrooxidation of some organic compounds, such as aromatic nitrocompounds, various pesticides including maleic hydrazide, 1, 3, 5-and 1, 2, 4-triazines, selenous acid, mitomycin C, phenols, etc . Structure-reactivity relationships are investigated, for example the transfer of electronic effects through an N-N single bond, ring formation of some 2-amino-1, 4-benzoquinones, or interactions between two reducible groups in a molecule.
