Zastosowanie
(1,2,5,6-Tetrahydropyridin-4-yl)methylphosphinic acid hydrate has also been used as γ-aminobutyric acid C (GABAc) blocker in retinal ganglion cells.
TPMA has been used as a GABAC receptor antagonist to study the role of inner retinal inhibition in midget ganglion cells. TPMPA has also been used to study the role of GABAC receptor antagonists in suppressing orientation selectivity in ganglion cells.
Działania biochem./fizjol.
TPMPA is a hybrid of isoguvacine and 3-APMPA designed to retain affinity for GABAC receptors but not to interact with GABAA or GABAB receptors. Electrical assays show that TPMPA is a competitive antagonist of cloned human mu 1 GABAC receptors expressed in Xenopus laevis oocytes (Kb approx. 2 μM). TPMPA is >100-fold weaker as an inhibitor of rat brain GABAA receptors expressed in oocytes (Kb approx. 320 μM) and has only weak agonist activity on GABAB receptors assayed in rat hippocampal slices (EC50 approx. 500 μM). TPMPA may be used to investigate GABAC receptor function in the outer retina and in any other areas of the nervous system in which these types of receptor are present.

The inhibitory neurotransmitter, GABA, activates a variety of receptors in all areas of the CNS. Two major subtypes of GABA receptors are well known: (1) GABAA receptors are ligand-gated Cl- channels that consist of a heteromeric mixture of protein subunits

In mammals, receptors for the inhibitory neurotransmitter gamma-aminobutyric acid (GABA) are divided into three pharmacological classes, which are denoted GABAA, GABAB, and GABAC. GABAC receptors are defined by their insensitivity to the GABAA receptor antagonist bicuculline and the GABAB receptor

Myopia (short-sightedness), usually caused by excessive elongation of the eye during development, has reached epidemic proportions worldwide. In animal systems including the chicken model, several treatments have been shown to inhibit ocular elongation and experimental myopia. Although diverse in their

We examined the contribution of the sodium channel isoform Nav1.8 to retinal function using the specific blocker A803467. We found that A803467 has little influence on the electroretinogram (ERG) a- and b-waves, but significantly reduces the oscillatory potentials (OPs) to
