Application

Dihydrokainic acid has been used as a glutamate transporter (GLT-1) inhibitor in the glutamate uptake assay of astrocytes and glial cells. It may be used as a GLT-1 inhibitor in Lateral habenula (LHb).

Biochem/physiol Actions

Dihydrokainic acid is a selective inhibitor of the GLT-1 glutamate transporter. At higher concentrations, dihydrokainate is a weak inhibitor of AMPA/kainate glutamic acid receptors.
Dihydrokainic favors neuronal cell death. It modulates anxiety and depression behaviors.

Glutamate transporter subtype 1 (GLT-1) activation is a promising - and understudied - approach for managing aspects of morphine tolerance caused by increased glutamatergic transmission. Identification of beta-lactam antibiotics as pharmaceuticals which activate GLT-1 transporters prompted us to hypothesize that

Mood disorders are associated with regional brain abnormalities, including reductions in glial cell and neuron number, glutamatergic irregularities, and differential patterns of brain activation. Because astrocytes are modulators of neuronal activity and are important in trafficking the excitatory neurotransmitter glutamate

Major depression is associated with both dysregulated glutamatergic neurotransmission and fewer astrocytes in limbic areas including the prefrontal cortex (PFC). These deficits may be functionally related. Notably, astrocytes regulate glutamate levels by removing glutamate from the synapse via the glutamate

Neuron-secreted factors induce astrocytic expression of the glutamate transporter, GLT-1 (excitatory amino acid transporter 2). In addition to their elaborate anatomic relationships with neurons, astrocytes also have processes that extend to and envelop the vasculature. Although previous studies have demonstrated
