Purity: ≥98%
SB 399885 hydrochloride is a novel, potent, brain penetrant, and orally bioactive 5-HT6 receptor antagonist. It exhibits selectivity for SR-6 over other serotonin receptors by more than 200 times (pKi values for human recombinant, native rat, and native human SR-6 receptors, respectively, are 9.11, 8.81, and 9.02). Blockade of postsynaptic 5-HT₆ receptors with systemic administration of SB-399885 and RO-4368554 increases W and reduces SWS and REMS during the light phase of the sleep-wake cycle. Moreover, SB-399885 suppresses REMS during the dark phase. Furthermore, it was established that giving the rat the 5-HT(2A) receptor antagonist EMD 281014 increases SWS in both light-dark cycle phases.

SB-399885 hydrochloride 10 mg/kg, when compared to the control vehicle, significantly increases wakefulness (W) (F(3,15)=3.32, P<0.05), while REM sleep, slow wave sleep, and the number of REM periods decrease (F(3,15)=4.0, P<0.01; F(3,15)=3.14, P<0.05, and F(3,15)=2.62, P<0.05, respectively). According to an analysis of sleep variables in 2-hour blocks, during the first 2-hour period, SB-399885 hydrochloride 10 mg/kg increases W (F(3,15)=5.48, P<0.01) and decreases SWS (F(3,15)=5.42, P<0.01) and REMS (F(3,15)= 4.05, P<0.01). Light sleep is enhanced by SB-399885 hydrochloride at doses of 5 and 10 mg/kg during the first (F(3,15)=3.46, P<0.01 and F(3,15)= 3.65, P<0.01, respectively) and second (F(3,15)=3.23, P<0.05 and F(3,15)=3.08, P<0.05) 2-hour recording periods. SB-399885 hydrochloride 10 mg/kg significantly increases REMS latency (F(3,15)=3.60, P<0.01) and reduces the number of REM periods during the first 2-h of recording (F(3,15)=3.88, P<0.01)[1].

Animal Protocol |
At the time of surgery, twelve male Wistar rats weighing between 350 and 400 g are utilized. For four weeks, beginning two hours after the start of the dark period, animals acclimated to a 12-hour light/12-hour dark cycle are given intraperitoneally SB-399885 hydrochloride 2.5, 5 and 10 mg/kg or a vehicle (1% aqueous solution of Tween 80) (n = 6). All twelve treatments are given to each animal. 15 minutes later, recordings start, and they last for 6 hours. Give the control solution and hydrochloride of SB-399885 no less than three days apart[1].

Solubility (In Vivo) |
Solubility in Formulation 1: 2.5 mg/mL (5.18 mM) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), suspension solution; with sonication.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution. Solubility in Formulation 2: 2.5 mg/mL (5.18 mM) in 10% DMSO + 90% (20% SBE-β-CD in Saline) (add these co-solvents sequentially from left to right, and one by one), suspension solution; with ultrasonication. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 900 μL of 20% SBE-β-CD physiological saline solution and mix evenly. Preparation of 20% SBE-β-CD in Saline (4°C,1 week): Dissolve 2 g SBE-β-CD in 10 mL saline to obtain a clear solution. View More
Solubility in Formulation 3: ≥ 2.5 mg/mL (5.18 mM) (saturation unknown) in 10% DMSO + 90% Corn Oil (add these co-solvents sequentially from left to right, and one by one), clear solution. |

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
