L-2-AMINO-4-SULFOBUTYRIC ACID Chemical Properties,Usage,Production

Uses

L-Homocysteic acid has been used to study hydrogen peroxide-mediated changes in physiological and pathological conditions in the nervous system.

Definition

ChEBI: A homocysteic acid with L-configuration.

Biochem/physiol Actions

L-Homocysteic acid (L-HCA) is an endogenous neurotransmitter ligand of NMDA (N-methyl-D-aspartate) receptors. It is an analog of glutamate and competitively suppresses glutamate-cystine (xc-) antiporter function in neurons, causing decrease in cysteine uptake.

in vivo

L-Homocysteic acid (intraperitoneal injection, 4-11 mmol/kg) elicits seizures in rats during early postnatal development[4].
L-Homocysteic acid (intraperitoneal injection, 100-1500 mg/kg) partially substitutes for NMDA, producing maximum values of 61-67% NMDA-lever responding at doses of 1000 and 560 mg/kg, respectively in Sprague-Dawley rats[5].

Animal Model:Male albino rats of the Wistar strain[4]
Dosage:4, 5.5, 8, 11 mM/kg
Administration:Intraperitoneal injection, daily for 14 days
Result:Induced flexion seizures at 4 mmol/kg.
Led to intense tail flicking, pivoting, and locomotion.
Decreased ECoG (electrocorticograms) activity for 5-9 min.

IC 50

NMDA Receptor: 14 μM (EC50)
