Descrizione

Applicazioni

(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.[1]

TPMA has been used as a GABA_C receptor antagonist to study the role of inner retinal inhibition in midget ganglion cells[2]. TPMPA has also been used to study the role of GABA_C receptor antagonists in suppressing orientation selectivity in ganglion cells[3].

Azioni biochim/fisiol

TPMPA is a hybrid of isoguvacine and 3-APMPA designed to retain affinity for GABA_C receptors but not to interact with GABA_A or GABA_B receptors. Electrical assays show that TPMPA is a competitive antagonist of cloned human mu 1 GABA_C receptors expressed in Xenopus laevis oocytes (Kb approx. 2 μM). TPMPA is >100-fold weaker as an inhibitor of rat brain GABA_A receptors expressed in oocytes (Kb approx. 320 μM) and has only weak agonist activity on GABA_B receptors assayed in rat hippocampal slices (EC₅₀ approx. 500 μM). TPMP_A may be used to investigate GABA_C receptor function in the outer retina and in any other areas of the nervous system in which these types of receptor are present.
