What's the difference between glyoxime and oxime?

Glyoxime


Definition:

  • (n.) A white, crystalline, nitrogenous substance, produced by the action of hydroxylamine on glyoxal, and belonging to the class of oximes; also, any one of a group of substances resembling glyoxime proper, and of which it is a type. See Oxime.

Example Sentences:

  • (1) The chelators EGTA, NTA, bipyridine, dimethyl glyoxime, salicylate, and Desferal were ineffective at preventing autooxidation.
  • (2) Prill and Hammer's method (4) for microdetermination of diacetyl was modified by several authors (1-3, 7), but retaining the same principle: diacetyl is converted into dimethylglyoxime by reaction with hydroxylamine; the oxime is subsequently converted into a pink ammonoferrous glyoximate and its colour is measured by absorbance at 530 nm.
  • (3) Among the compounds tested, interesting structures are those of oximes bearing a thioether substituent [RA 49 (Table 1) and RA 59 (Table 2)] chloro derivative of MINA [RA 55 (Table 2)] and dipyridyl glyoxime methiodide RA 56 (Table 1).

Oxime


Definition:

  • (n.) One of a series of isonitroso derivatives obtained by the action of hydroxylamine on aldehydes or ketones.

Example Sentences:

  • (1) The chemistry involved reaction rate constant measurements of MSF hydrolysis and for reactions with phenolic, amine, oxime, hydroxamic acid, phenyl N-hydroxycarbamate, and hydroxylamine compounds and cupric imidazole and bipyridyl complexes.

  • (3) Because of the suspicion that the oximino steroids were acting postcoitally, 17-beta-acetoxy-19-norandrost-4-en-3-one oxime was studied for its postcoital activity in rats.
  • (4) A radioiodinated derivative of estriol (6-ketoestriol-6(o-carboxymethyl)oxime-[125I]tyrosine methyl ester) is added to the column, followed by a limiting amount of antiserum.

  • (6) The syntheses of the secondary hydroxylamines of nor1chlorpromazine and nor1promazine via their corresponding primary hydroxylamines and oximes are described.

  • (8) A new radiopharmaceutical, 99Tcm-hexamethylpropyleneamine oxime (99Tcm-HM-PAO) has shown considerable promise for single photon emission tomographic (SPECT) imaging of the brain.
  • (9) In addition, a preliminary pharmacokinetic study of the imidazolium oxime in rabbits was carried out using this method.
  • (10) As revealed by comparison of the prophylactic effects of HI-6 and the non-oxime bispyridinium compound SAD-128, competitive inhibition of AChE plays a minor role as a protective mechanism.
  • (11) In atropine-protected, soman-poisoned mice HLö 7 was three times more potent than HI 6 (protective ratio 5 versus 2.5), and in sarin-poisoned mice HLö 7 was 10 times more potent than HI 6 (protective ratio 8 for both oximes).
  • (12) We have prepared four new oximes, 1b-e, which conform to the general structure RCH2COCH = NOH where R = CH3S, CH3SO, CH3SO2, and (CH3)2S+, respectively, and have the same E configuration as the parent 2-oxopropanal oxime 1a (R = H, MINA).
  • (13) The pharmacokinetics, pharmacodynamics, and toxicity of the oxime HGG 12 were studied in conscious and anesthetized dogs.
  • (14) To study the pathophysiological mechanisms of hyperventilation-induced EEG showing, i.e., the so-called 'buildup' phenomenon, changes in regional cerebral blood flow (rCBF) were investigated before and during the phenomenon in a 16-year-old woman with headache, thought to be of neurotic origin, by subtraction technique of brain images with single photon emission computed tomography using technetium-99m hexamethyl-propyleneamine oxime (99mTc-HMPAO).
  • (15) The properties of oxime derivatives of mitochondrial aspartate aminotransferase with hydroxylamine and 6 compounds H2NOR were studied by absorption spectroscopy and circular dichroism in solution and by linear dichroism in crystals.

  • (17) Since the antisera (with the exception of that for thromboxane B2) do not recognise the underivatised PG or the oxime (=NOH) form, oxime formation can be carried out in parallel with methyl oxime formation and the oximated portion of the sample can act as a "reference" for the methyl oximated portion, which will allow non specific interference to be recognised.
  • (18) To find antiviral agents, various sulfonamidobenzophenone oximes (II) were synthesized from the appropriate m-sulfonamidobenzophenones by hydroxylamine reaction.
