Usage

Description

THIP HYDROCHLORIDE, also known as Gaboxadol HCl, is a GABA-A receptor agonist with the chemical formula (64603-91-4). It is primarily recognized for its hypnotic properties and is used as a therapeutic agent in the treatment of various conditions.

Uses

Used in Pharmaceutical Industry:
THIP HYDROCHLORIDE is used as a GABAa agonist for its hypnotic properties, helping in the treatment of sleep disorders and other related conditions. Its agonistic action on GABA-A receptors promotes relaxation and sedation, making it a valuable compound in the development of medications for insomnia and other sleep-related issues.
Used in Neurological Research:
In addition to its pharmaceutical applications, THIP HYDROCHLORIDE is also used as a GABAc antagonist in neurological research. This dual functionality allows scientists to study the effects of GABA-A and GABA-c receptors separately, leading to a better understanding of their roles in the central nervous system and the development of targeted therapies for neurological disorders.

Biological Activity

Systemically active GABA A receptor agonist and GABA C receptor antagonist. Displays antinociceptive, anticonvulsant and sedative effects. Hypnotic agent that enhances delta activity within non-REM sleep in rats.
