5-HT1E Receptor 1.1 nM (Ki) 5-HT1F Receptor

Despite its low affinity for other receptors [5-HT1A (63 nM), 5-HT1B (126 nM), 5-HT1D (63 nM), 5-HT2A (1259 nM), 5-HT2B (100 nM), 5-HT2C (316 nM), 5-HT6 (>10,000 nM), 5-HT7 (>10,000 nM), D2 (501 nM), D3 (631 nM), and α1B-adrenoceptors (1259 nM)], BRL54443 binds with high affinity at 5-HT1F receptors.
In DG membranes, BRL54443 selectively stimulates 5-HT1E receptors and potently inhibits forskolin-dependent cAMP production (IC50=14 nM). BRL 54443 also induces contraction (-log EC50=6.52).
has not independently confirmed the accuracy of these methods. They are for reference only.

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.
