Catalog Number: 0505
Biological Activity
A complex of closely related alkaloid salts. Binds with high affinity to the GABAA receptor Cl- channel, producing an allosteric interaction with the benzodiazepine site. Also interacts with central dopaminergic, serotonergic and adrenergic (α1) receptors. Displays antiproliferative activity in vitro (IC50 = 18 - 38 μM in prostate cancer cells) and exhibits cognition-enhancing, anticonvulsant and sedative activity in vivo. Orally active.
