SMILES: O[C@@]([C@@](CCC1)([H])N1C2=O)(O[C@](NC([C@@H](CN(C)[C@]3([H])C4)C[C@]3([H])C5=C6C4=CNC6=CC=C5)=O)(C)C7=O)N7[C@H]2CC8=CC=CC=C8.CS(=O)(O)=O
Biological Activity: Dihydroergotamine mesylate is a blood-brain barrier-permeable semi-synthetic ergot alkaloid, acting as a full agonist of 5-HT1B/1D receptors (Ki values of 0.3 nM and 2.5 nM, respectively; functional IC50 values of 2 nM and 2.2 nM, respectively). Dihydroergotamine mesylate inhibits Forskolin (HY-15371)-stimulated cAMP accumulation, possesses α-adrenergic receptor antagonistic activity and weak dopaminergic agonistic activity. It mediates intracranial cerebrovascular contraction, inhibits the release of neuropeptides such as CGRP/substance P, and suppresses neurogenic inflammation by activating 5-HT1B/1D receptors in the trigeminovascular system. Dihydroergotamine mesylate binds to the catalytic site of Trypanosoma cruzi trypanothione reductase and exhibits trypanocidal activity in vitro. Dihydroergotamine mesylate can be used in studies related to migraine and trypanosome infections[1][2][3][4].
