Description

L-Homocysteic acid (L-HCA) is an endogenous excitatory amino acid that acts as a NMDA receptor agonist (EC50: 14 μM). L-Homocysteic acid is neurotoxic, and can be used in the research of neurological disorders[1][2][3].

IC50 & Target[1]

NMDA Receptor

14 μM (EC50)

In Vitro

L-Homocysteic acid activates NMDA receptor with an EC50 value of 14 μM[1].
L-Homocysteic acid (100 μM) induces large currents (1.8 nA) that is insensitive to the NMDA receptor-antagonist mixture in Purkinje cells[1].
L-Homocysteic acid (250 μM, 30 min) potently induces an acute excitotoxic reaction in ex vivo chick embryo retina[2].
L-Homocysteic acid (0-2 mM, 48 h) induces a concentration-dependent neurotoxic effect in rat primary neurons[3].

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].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
