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].

Naratriptan-d3
0 ImagesCat. No.: HY-B0197SCAS No.: 1190043-69-6Synonyms: GR-85548A-d3-1Naratriptan-d3 (GR-85548A-d3) is the deuterium labeled Naratriptan (HY-B0197). Naratriptan is a selective 5-HT1B/1D receptor agonist. Naratriptan is peripherally active and has good oral bioavailability, inducing cranial artery vasoconstriction by activating 5-HT1B/1D receptors (EC50=0.11 μM for dog basilar artery). Naratriptan also inhibits trigeminal nerve-mediated dural neurogenic plasma extravasation and reduces sterile inflammation. Naratriptan is mainly used in the research of acute migraine, targeting cranial vascular and neuroinflammatory mechanisms.
