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 SB408124 is a non-peptide antagonist for OX1 receptor with Ki of 57 nM and 27 nM in both whole cell and membrane, respectively, exhibits 50-fold selectivity over OX2 receptor.
in vitro SB-408124 binds hypocretin type 1 receptor (HcrtR1) with pKi values of 7.57. Calcium mobilization studies shows that SB-408124 is a functional antagonist of the OX1 receptor with a affinity of approximately 50-fold selectivity over the OX2 receptor. [1] A recent study indicates that pretreatment of primary cultures of rat astrocytes with SB-401824 before Orexin A administration significantly reduced the stimulatory action of Orexin A on both basal and forskolin-acivated cAMP production. [2]
in vivo SB-408124 (30 μg/10 μL, administered intracerebroventricularly) decreases Orexin-A induced water intake in Wistar rats. Intracerebroventricularly administered Orexin-A (30 μg/10 μL) blocks the vasopressin (VP) level increase induced by either histamine or 2.5% NaCl administration, and this blocking effect is moderated by pretreatment with SB-408124. [3] Intracerebroventricular pretreatment with SB-408124 (50 mM, 5 μL/h) prevents Bicuculline (BIC)-induced increases in endogenous glucose production (EGP). [4]

キナーゼアッセイ Whole cell binding assays
After overnight culture in 96-well Packard Cultur plates, the medium is discarded and cells are incubated in buffer containing 150 mM NaCl, 20 mM HEPES and 0.5% bovine serum albumin (pH 7.4) for 60 minutes at 25 °C. Saturation studies are carried out by incubating cells with a range of concentrations of [3H]SB-408124 (0.2–24 nM); the total assay volume is 250 μL. Protein content is assayed by lysing cells with 0.1M NaOH and using the Bradford method with bovine serum albumin (BSA) as a standard. Association kinetic studies are performed by measuring the specific binding of [3H]SB-408124 (3 nM) at 1–60 minutes after addition of [3H]SB-408124. All assays are terminated by washing the cells three times with 250μL ice-cold phosphate-buffered saline. A volume of 100 μL of Microscint 40 is added to each well and the plate is left at room temperature for 2 hours. Cell-associated radioactivity is then measured using a Packard Topcount, with a count time of 2 minute/well.
