Biological Activity

Benzodiazepine inverse agonist. Binds with high affinity to both diazepam-sensitive (DS) and diazepam-insensitive (DI) GABAA receptors (Ki values are ~ 0.2 and ~ 2.6 nM for DS and DI receptors respectively). Antagonizes effects of ethanol on locomotor behavior and suppresses ethanol intake in alcohol-preferring rats.

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.

Pain

Pain Poster

Peripheral sensitization is the reduction in the threshold of excitability of sensory neurons that results in an augmented response to a given external stimulus. This poster outlines the excitatory and inhibitory signaling pathways involved in modulation of peripheral sensitization. The role of ion channels, GPCRs, neurotrophins, and cytokines in sensory neurons are also described.
