Product description

Description

BRL-15572 2Hcl is a 5-HT1D receptor antagonist with pKi of 7.9, also shows a considerable affinity at 5-HT1A and 5-HT2B receptors, exhibiting 60-fold selectivity over 5-HT1B receptor. IC50 Value: 7.9(pKi) Target: 5-HT1D Receptor in vitro: BRL-15572 displays high affinity and selectivity for h5-HT1D receptors. BRL-15572 has 60-fold higher affinity for h5-HT1D than 5-HT1B receptors. BRL-15572 binds to h5-HT1B and h5-HT1D receptors with pKB of less than 6 and 7.1, respectively. BRL-15572 stimulates [35S]GTP γ S binding in both cell lines, with potencies that correlated with their receptor binding affinities in both h5-HT1B and h5-HT1D receptor expressing cell lines. BRL-15572 reveals receptor binding affinities for 5-HT1A, 5-HT1B, 5-HT1E, 5-HT1F, 5-HT2A, 5-HT2B, 5-HT2C, 5-HT6 and 5-HT7 with pKi of 7.7, 6.1, 5.2, 6.0, 6.6, 7.4, 6.2, 5.9 and 6.3, respectively. In the h5-HT1D cell line, both BRL-15572 (1 μM) shifts the 5-HT concentration response curve with pKB of 7.1, respectively. BRL-15572 does have moderately high affinity at human 5-HT1A and 5-HT2B receptors. in vivo: In diabetic pithed rats, administration of the selective 5-HT1D receptor antagonist BRL-15572 (2 mg/kg) does not modify the decreased HR induced by vagal electrical stimulation. The effects of L-694,247 (50 μg/kg), a selective agonist for non-rodent 5-HT1B and 5-HT1D receptors, on the vagally induced bradycardia are not apparent after pretreatment with BRL-15572.
