30.0mg/ml Taking the 1 mL working solution as an example, add 300 μL of 100 mg/ml clarified propylene glycol stock solution to 50 μL of Tween 80, mix evenly to clarify it; then continue to add 650 μL of D5W to adjust the volume to 1 mL. The mixed solution should be used immediately for optimal results. 
* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.

生物活性

製品説明 BRL 54443 is a 5-HT1E and 5-HT1F receptor agonist with pKi of 8.7 and 9.25, respectively, with a weak binding affinity for 5-HT1A, 5-HT1B, 5-HT1D receptors.
in vitro BRL 54443 has also measurable affinity for the 5-HT2A receptor. BRL 54443 induces contraction with a −logEC50 of 6.52. Contraction caused by BRL 54443 is likely mediated through stimulation of 5-HT5-HT2A receptors. [2]
in vivo BRL 54443 induces an immediate dose-dependent maximal intragastric volume increase vs. saline. [1]

キナーゼアッセイ Membrane preparation and binding assay
The binding affinity of a set of 5-HT receptor agonists and antagonists (samples) at 5-HT1F receptors is tested. To do this h5-HT1F-HEK 293 cells are cultured in Petri dishes till 90% confluency is reached. The cells are scraped from the plates and suspended in 50 mM Tris–HCl buffer (pH 7.4). After centrifugation (23,500 × g) the pellet is suspended in 5 mM Tris–HCl buffer (pH 7.4) and homogenized with an Ultra Turrax homogeniser. The membranes are collected by centrifugation at 18,000 × g for 20 minutes, resuspended in 50 mM Tris–HCl (pH 7.4) and stored at −80 °C. At the day of the binding experiment, the membranes are defrosted and homogenized. The protein concentration is determined using the Bradford protein assay and the membranes are diluted in the assay buffer down to 65 μg protein/mL (50 mM Tris–HCl, 10 mM MgCl2, 1 mM EGTA and 10 μM pargyline, pH 7.4). Assay mixtures (0.5 mL) contained 0.4 mL membrane preparation and 2 nM of tritiated 5-HT (118 Ci/mmol); to determine the non-specific binding 1 μM sumatriptan is added. Per sample studied 15 mixtures are created containing different concentrations (10 μM–1 pM) of the sample. The mixtures are then incubated for 60 minutes at 25 °C (protected from light), incubation is stopped by rapid filtration on a Filtermate 96. Bound radioactivity is determined by liquid scintillation counting. Data are analysed graphically with inhibition curves and IC50 values are derived. Ki values are calculated according to the equation Ki =IC50/(1+(C/Kd)), with C as the concentration of [3H]5-HT (2 nM) and Kd as the equilibrium dissociation constant of [3H]5-HT (2.61 nM).
