5-Hydroxytryptamine-moduline, also known as 5-HT-moduline or serotonin-moduline as well as Leu-Ser-Ala-Leu (LSAL), is an endogenous neuropeptide and high-affinity serotonin 5-HT1B and 5-HT1D receptor negative allosteric modulator.[1][2][3][4][5][6][7] It is produced in the brain and is co-localized with serotonin 5-HT1B receptor-expressing neurons.[2][8] The compound has been shown to induce desensitization of serotonin 5-HT1B receptors.[2][9] It has been found to increase dopamine release in the striatum in rodents.[10] By inhibiting serotonin 5-HT1B autoreceptors, 5-HT-moduline disinhibits serotonin release and may have antidepressant potential.[1][2] Antibodies and small-molecule antagonists against 5-HT-moduline like HG1 have been found to produce anxiolytic-like effects in rodents.[1][2][11][12][13][14] 5-HT-moduline was first described in the scientific literature by 1996.[2][3] Analogues of 5-HT-moduline have been studied.[15]
