L-655,708 Chemical Properties,Usage,Production

Uses

L-655,708 has been used as an α5 GABAA receptor inverse agonist to inhibit the discriminative stimulus of propofol in a dose-dependent manner.

Biological Activity

Potent, selective inverse agonist for the benzodiazepine site of GABA A receptors containing the α 5 subunit (K i = 0.45 nM). Displays 50-100-fold selectivity over GABA A receptors containing α 1, α 2, α 3 or α 6 subunits in combination with β 3 and γ 2. Enhances LTP in? a mouse hippocampal slice model and increases spatial learning, without displaying proconvulsant activity.

Biochem/physiol Actions

L-655,708 is an inverse agonist of the α5 γ-Aminobutyric acid type A (GABAA) receptor. It has an ability to increase cognition in rats.

in vivo

L-655708 at 0.7 mg/kg, administered intraperitoneally, would result in 60-70% occupancy of α5 GABAA receptors with limited binding to α1, α2, and α3 subunit-containing GABAA receptors and no significant off-target behavioral effects, such as sedation and motor impairment.
