Description

(1,2,5,6-tetrahydropyridine-4-yl)methylphosphinic acid (TPMPA) is a competitive antagonist of gamma-aminobutyric acid (GABA)C receptors.

CNS Activity

CNS Active
4002
Curator's Comment: Centrally administered TPMPA is CNS active in animals. However, TPMPA does not cross the blood-brain barrier because no central effects upon systemic administration have been reported to date. No human data available.

Sample Use Guides

In Vivo Use Guide
TPMPA (100 μmol/rat) was administered intracerebroventricularly (ICV)
Route of Administration: Other
In Vitro Use Guide
Muscimol (100 μM) caused a transient increase of the [Ca(2+)]i in RPE cells regardless of whether Ca(2+) was added to the buffer. Muscimol-induced increases in the [Ca(2+)]i were inhibited by pretreatment with picrotoxin (300 μM) or TPMPA (500 μM).
