5-HT1F

5-HT1F receptor is a subtype of 5-HT receptor that binds the endogenous neurotransmitter serotonin. It is a G protein-coupled receptor (GPCR) that is coupled to Gi/Go and is expressed throughout the central nervous system (CNS).

Function

The 5-HT1F receptor is thought to play a role in the pathophysiology of migraine. Activation of this receptor has been shown to inhibit the release of calcitonin gene-related peptide (CGRP) from neurons in the trigeminal ganglion. CGRP is thought to play a key role in the pathogenesis of migraine. Therefore, 5-HT1F receptor agonists may be useful in the treatment of migraine.

Ligands

Several selective 5-HT1F receptor agonists are available for experimental use, including LY334370 and LY344864. These compounds have been shown to be effective in animal models of migraine. In addition, the non-selective 5-HT1F receptor agonist sumatriptan, which is used clinically for the treatment of migraine, has been shown to activate the 5-HT1F receptor.

Clinical significance

The 5-HT1F receptor is a potential target for the treatment of migraine. Several 5-HT1F receptor agonists are currently under development for this indication. These include lasmiditan, which is in phase III clinical trials, and LY334370, which has completed phase II clinical trials.
