BRL-54443 BiologicalActivity

Description	BRL 54443 is a potent 5-HT1E/1F receptor agonist (pKi values are 8.7 and 8.9 respectively); displays > 30-fold selectivity over other 5-HT and dopamine receptors.IC50 value: 8.7(pKi, 5-HT1E); 8.9 (pKi, 5-HT1F) Target: 5-HT1E/1F receptorin vitro: BRL 54443 is a potent 5-ht1E/1F receptor agonist (pEC50 values are 8.5 and 8.6 respectively). Displays > 30-fold selectivity over other 5-HT and dopamine receptors (pKi 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-HT1E, 1F, 1A, 1B, 1D, 2A, 2B, 2C, 4, 7, D2 and D3 receptors respectively). Induces 5-HT2A receptor-mediated mouse aortic contraction in vitro (pEC50 = 6.52). Active in vivo. In DG membranes, BRL54443, a 5-ht(1E) /5-HT(1F) agonist, selectively stimulated 5-ht(1E) receptors and potently inhibited forskolin-dependent cAMP production (IC50 = 14 nM) [2]. The 5-HT(1E/1F) receptor agonist BRL 54443 also induced contraction (-log EC(50) = 6.52) [1].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].
