Acciones bioquímicas o fisiológicas

Dihydrokainic favors neuronal cell death. It modulates anxiety and depression behaviors.
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.

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...

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...

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...

Isoflurane is a widely used anesthetic which safely and reversibly induces deep coma and associated burst suppression (BS) electroencephalographic patterns. Here we investigate possible underlying causes for the state of cortical hyperexcitability which was recently shown to be one of...
