5-HT1 Receptor
5-HT1 receptors are serotonin-activated GPCRs within the 5-HT receptor family, excluding ionotropic 5-HT3 receptors[1]. Mechanistically, 5-HT1D receptors inhibit glutamate release, while 5-HT1A receptors inhibit NMDA/AMPA-linked cGMP responses in rat cerebellum[2]. In antidepressant research, presynaptic 5-HT1A and 5-HT1B autoreceptors reduce serotonergic function, whereas postsynaptic 5-HT1A stimulation appears beneficial[3]. Compared with related isoforms, 5-HT1A, 5-HT1B, 5-HT1D, and 5-HT1F share high sequence homology, which complicates subtype-specific ligand design[4]. For experimental applications, 2-aminotetralin-type agonists showed high affinity and subtype-dependent efficacy across 5-HT1 receptors, supporting selective ligand discovery[4].

Dihydroergotamine mesylate
0 ImagesDihydroergotamine 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.
