Key Product Details
Description
Positive allosteric modulator of GABAA receptors; displays subunit selectivity
Product Description
DS2 is a positive allosteric modulator of GABAA receptors. Potentiates GABA-evoked currents mediated by α4β3δ receptors (EC50 = 142 nM, in vitro). Displays complex selectivity profile, with selectivity for δ-containing receptors (α4/6βxδ > α1βxδ >> γ2 > α4β3 GABAA receptors). Enhances tonic currents of thalamocortical neurons in wild-type mice.Product Specifications
