Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system. Compound: 2-Amino-4,5-dihydrothiazole-4-carboxylic acid, is researched, Molecular C4H6N2O2S, CAS is 2150-55-2, about Seizures and selective CA-1 hippocampal lesions induced by an excitotoxic cyanide metabolite, 2-iminothiazolidine-4-carboxylic acid.Related Products of 2150-55-2.
Excitatory amino acid (EAA)-like and excitotoxic properties of the secondary metabolite of cyanide, 2-iminothiazolidine-4-carboxylic acid (2-ICA), were evaluated because of its possible role in cyanide-induced neurotoxicity. Intracerebroventricular (i.c.v.) injections of 2-ICA in mice produced wild-running seizures that were qual. and quant. similar to seizures observed with glutamate. 2-ICA, kainate, and proline seizures were prevented by both the NMDA and non-NMDA antagonists, MK-801 and CNQX, resp. In contrast, NMDA-induced seizures were prevented by MK-801, but not CNQX. When infused i.c.v. in rats over a 7-day period, 2-ICA produced extensive and selective loss of CA-1 pyramidal neurons of the hippocampus. In hippocampal slices preloaded with D-[3H]aspartate, 2-ICA superfusion did not evoke release nor significantly augment potassium-stimulated release of the radiolabeled transmitter. These findings indicate 2-ICA has excitotoxic properties and its role in cyanide neurotoxicity deserves further study.
