Disease relevance of NSC62343


Psychiatry related information on NSC62343

  • Holeboard maze-learning deficits and brain monoaminergic neurotransmitter concentrations in rats after intracerebroventricular injection of 3-bromopyruvate [6].
  • Because comparable changes of PDHc and muscarinic receptors are found in dementia of Alzhemier type, the model of bromopyruvate inhibition of PDHc in rats is suggested to be useful for experimental dementia research [7].

High impact information on NSC62343

  • Covalent modification of an active site residue, Cys 191, by the inhibitor 3-bromopyruvate traps the enzyme in a catalytic conformation with the active site completely inaccessible to solvent [8].
  • Although glucose metabolism was preserved, indicating that the neuronal activities were enhanced, cerebral blood flow increase during cortical neuronal activation was abolished by bromopyruvate injection into only the cerebral cortex and not other cholinergic systems [9].
  • In extending these studies, 3-bromopyruvate was found to be over 20 times less effective in inhibiting glyceraldehyde-3-phosphate dehydrogenase in intact erythrocytes than in trypanosomal cells [10].
  • 2. Moreover the dependence of the reactivity of Cys-47 toward bromopyruvate and iodoacetamide with pH resembles that found for the functional sulfhydryls of thiol proteases, which have very low pKa values and exist mainly as a mercaptide-imidazole ion pair [11].
  • The phenylalanine-sensitive isozyme of 3-deoxy-D-arabino-heptulosonate-7-phosphate synthase from Escherichia coli was inactivated by the sulfhydryl modifying reagents 5,5-dithiobis-(2-nitrobenzoate), bromopyruvate, and N-ethylmaleimide and protected from inactivation by the presence of its metal activator, Mn2+, and substrate, phosphoenolpyruvate [12].

Associations of NSC62343 with other chemical compounds

  • The Cys-294----Ser mutant enzyme is virtually identical to the wild type with respect to pyridoxal phosphate binding (KCO = 2 microM), cofactor absorption spectrum (lambda max = 420 and 337 nm) and pH dependence (pK alpha = 7.3), pH profile for catalysis, and rate of bromopyruvic acid inactivation [20].
  • A possible impact of this observation with respect to the different responses of isocitrate lyases and PrpB upon treatment with the common inhibitor 3-bromopyruvate is discussed [21].
  • In both types of inhibition of E1, reaction of 1 mol of bromopyruvate/mol of E1 chain is required for complete inactivation, and all the evidence is consistent with reaction taking place at or near the pyruvate binding site [22].
  • It is based on reaction of bromine with enolpyruvate in acid, derivatization of formed bromopyruvate with thionitrobenzoate, and resolution by reversed-phase HPLC of the thioether derivative [23].
  • Malic enzyme from pigeon liver is alkylated by the substrate analogue bromopyruvate, resulting in the concomitant loss of its oxidative decarboxylase and oxalacetate decarboxylase activities, but not its ability to reduce alpha-keto acids [17].

Gene context of NSC62343


Analytical, diagnostic and therapeutic context of NSC62343

  • Based on these observations and a report that KDO 8-P synthase is inactivated in a time-dependent manner with 3-bromopyruvate and that the substrate PEP protects against this inactivation, all four cysteines (38, 166, 206, and 249) were individually mutated to alanines via a modified PCR methodology [28].
