BRL-15,572 is a drug which acts as a selective antagonist for the serotonin receptor subtype 5-HT1D, with around 60x selectivity over other related receptors. The 5-HT1D receptor has a very similar pharmacology to the closely related 5-HT1B receptor, and most older ligands for these receptors bind to both subtypes with approximately equal affinity, so development of compounds such as BRL-15572 which are able to selectively block the 5-HT1D subtype while leaving 5-HT1B unaffected, have been a significant advance which has helped scientists in researching the function of these serotonin receptor subtypes.[1][2] One function of the 5-HT1D receptor this research has revealed is its role in modulating release of the neurotransmitter glutamate in the brain,[3] as well as functions in regulation of cerebral blood pressure which are important in the pathogenesis of migraine headaches.[4]
