BRL 54443 Chemical Properties,Usage,Production
Uses
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 .
Synthesis
111963-87-2
57477-39-1
1. 5-methoxy-3-(1-methyl-4-piperidinyl)indole (2.30 g, 9.4 mmol) was dissolved in 30 mL of 30% hydrobromic acid acetic acid solution. 2. The reaction mixture was placed in a sealed tube and heated at 105 °C for 72 hours. 3. Upon completion of the reaction, it was cooled to room temperature and concentrated under vacuum to remove the solvent. 4. the concentrated residue was dissolved in water and the pH was adjusted to about 13 with 5N aqueous sodium hydroxide solution. 5. Vacuum concentration is performed again and the residue is purified by silica gel column chromatography using a methanol/dichloromethane solution of 20% 2M ammonia as eluent. 6. The target fraction was collected, concentrated under vacuum and the residue was dissolved in methanol. 7. Dowex? 50X8-200 ion exchange resin (25 g) was added and stirred overnight at room temperature. 8. Filter the mixture and wash the resin sequentially with water and methanol. 9. Mix the resin with 100 mL of 2 M ammonia in methanol, stir overnight and filter. 10. The filtrate was concentrated in vacuum to give 1.84 g (85% yield) of 3-(1-methylpiperidin-4-yl)-1H-indol-5-ol, which could be used in subsequent steps without further purification. 11. Elemental analysis results: For C13H17N3O, calculated values: C, 67.53; H, 7.36; N, 18.18. measured values: C, 67.24; H, 7.37; N, 18.38.
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].
IC 50
5-HT1E Receptor: 1.1 nM (Ki); 5-HT1F Receptor: 0.7 nM (Ki); 5-HT1A Receptor: 63 nM (Ki); 5-HT1B Receptor: 126 nM (Ki); 5-HT1D Receptor: 63 nM (Ki); 5-HT2A Receptor: 1259 nM (Ki); 5-HT2B Receptor: 100 nM (Ki); 5-HT2C Receptor: 316 nM (Ki); 5-HT6 Receptor: >10,000 nM (Ki); 5-HT7 Receptor: >10,000 nM (Ki)
