Dihydroergotoxine mesylate_product_DataBase

Bioactivity	Dihydroergotoxine mesylate is 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.IC50 value:Target: Dihydroergotoxine mesylate also interacts with central dopaminergic, serotonergic and adrenergic (α1) receptors. Dihydroergotoxine mesylate displays antiproliferative activity in vitro (IC50 = 18 - 38 μM in prostate cancer cells) and exhibits cognition-enhancing, anticonvulsant and sedative activity in vivo.
