Biological Activity for SR 95531 hydrobromide

SR 95531 hydrobromide is a selective, competitive GABAA receptor antagonist and allosteric inhibitor (IC50 = 200 nM). SR 95531 displaces [3H]-GABA from rat brain membranes with a Ki of 150 nM. Unlike Bicuculline (Cat. No. 0130), SR 95531 selectively antagonizes GABA-induced Cl- currents with little action on Pentobarbitone-induced currents (Cat. No. 4579). SR 95531 can act as an agonist at high concentrations (>100 μM) and is a weak agonist at GABAA receptors with α1β2(Y157S)γ2L subunits. SR 95531 also acts as a competitive antagonist of recombinant glycine receptors and exhibits greater potency at glycine receptors containing β subunits.

Addiction Poster

The key feature of drug addiction is the inability to stop using a drug despite clear evidence of harm. This poster describes the brain circuits associated with addiction, and provides an overview of the main classes of addictive drugs and the neurotransmitter systems that they target.
