Carboxymethoxylamine hemihydrochloride Chemical Properties,Uses,Production
Chemical Properties
white to off-white crystalline powder or crystals
Uses
Carboxymethoxylamine hemihydrochloride is a bifunctional linking reagent that undergoes condensation with aldehydes and ketones to form oximes. It can also be used as a potent inhibitor of (pyridoxal 5’-phosphate) PLP-dependent β-lyases.
Definition
ChEBI: (aminooxy)acetic acid hemihydrochloride is the hemihydrochloride salt of (aminooxy)acetic acid. It is a malate-aspartate shuttle (MAS) inhibitor which also inhibits the GABA degradating enzyme 4-aminobutyrate aminotransferase and cystathionine beta-synthetase. It contains an (aminooxy)acetate.
Preparation
Carboxymethylhydroxylamine hemihydrochloride is obtained by reacting O-carboxymethylacetone oxime with hydrochloric acid.
in vivo
The accumulation of GABA in cerebellum and whole brain is initially very rapid, being significantly increased already 5 min after the injection of Aminooxyacetic acid hemihydrochloride (AOAA). The rapid initial accumulation becomes gradually slower and maximal levels (400 to 600 % of the control levels) are reached 2 to 6 h after Aminooxyacetic acid hemihydrochloride. Still 24 h after Aminooxyacetic acid hemihydrochloride the GABA levels are elevated by about 250%. From 2 to 6 h after Aminooxyacetic acid hemihydrochloride the convulsions are completely blocked. Twenty four hours after Aminooxyacetic acid hemihydrochloride the convulsions are almost identical to the controls[2].
