Biological Activity for TP 003

TP 003 is a GABAA receptor partial agonist that demonstrates affinity for the benzodiazepine site. Potentiates GABAA α3 response with high efficacy. Produces anxiolytic-like effects in rodent elevated plus maze via action at GABAA α2 subtype receptors. Also evokes GABAA α1 mediated sedation and GABAA α3 mediated muscle relaxation in mice.
