BRL-53443 is a potent 5-HT and dopamine receptor agonist. Neuroresearch product. | [Definition]
ChEBI: 3-(1-methyl-4-piperidinyl)-1H-indol-5-ol is a member of hydroxyindoles. | [Biological Activity]
A potent 5-ht 1E/1F receptor agonist (pEC 50 values are 8.5 and 8.6 respectively). Displays > 30-fold selectivity over other 5-HT and dopamine receptors (pK i values are 8.7. 8.9, 7.2, 6.9, 7.2, 5.9, 7.0, 6.5, < 6, < 6, 6.3 and 6.2 for human 5-HT 1E , 1F , 1A , 1B , 1D , 2A , 2B , 2C , 4 , 7 , D 2 and D 3 receptors respectively). Induces 5-HT 2A receptor-mediated mouse aortic contraction in vitro (pEC 50 = 6.52). Active in vivo . | [in vivo]
Reduction of flinching was considered as antinociception. Ipsilateral, but not contralateral, peripheral administration of BRL54443 (5-HT(1E/1F); 3-300 microg/paw) significantly reduced formalin-induced flinching in rats[3].
