体外研究 |
SB-649868 is identified as one the most in vitro potent dual OX1 and OX2 receptor antagonist known at that time (pKi=9.4 and 9.5 at the OX1 and OX2 receptor,respectively) .SB-649868 antagonizes orexin-A-induced inositol 1 phosphate (IP1) accumulation with the following pKB value (OX1=9.67;OX2=9.64).SB-649868 displaces the [3H]ACT-078573 receptor binding with the following pKi values:OX1=9.27;OX2=8.91.Increasing concentrations of SB-649868 (0.3nM-30nM) induces a rightward shift of the orexin-A CRCs with a depression of the agonist efficacy suggesting a clear non-surmountable behavior.The calculated apparent pKb values are 9.67±0.03 and 9.64±0.07 for OX1 and OX2. |

体内研究 |
Pharmacokinetic studies in the male CD rat,performed at 1mg/kg,iv and 3mg/kg,po,demonstrate an excellent pharmacokinetic profile for a hypnotic agent featuring moderate clearance in plasma (Clp=24mL/min/kg), short half-life of (<0.6h) and a low volume of distribution (Vss=1.1l/kg),coupled with excellent oral bioavailability (F=85%) and good exposure in plasma (Cmax=333ng/mL).A brain to blood ratio (B/B) of 0.1:1 is observed 1h after iv administration,a value in line with the expected partition between the two compartments based on the lower tissue binding observed in vitro in brain tissues (fraction unbound/brain=5.28%) with respect to plasma proteins (fraction unbound/plasma=1.34%).SB-649868,administered orally 3h before OX-A injection at doses of 1,3 and 10mg/kg,causes a dose-dependent reduction of OX-A induced grooming as measured by total time spent grooming and number of grooming bouts (p<0.01 at 3 and 10mg/kg po).From dissociation kinetic studies using [3H]ACT-078573,the calculated long half-life,(t1/2) supports the nonsurmountability profile of SB-649868 (t1/2=35.91 min) at OX1 orexin receptor.The long or moderately long t1/2values for SB649868 at OX2 orexin receptor (t1/2=8.09 min). |

Chinese Hamster Ovary (CHO) cells stably transfected with human OX1 orexin receptor are cultured in Dulbecco's modified Eagle's medium F12 Ham,supplemented with 10% fetal bovine serum (FBS),2mg/mL glutamine,600μg/ml geneticin at 37℃ in an atmosphere of 95% air and 5% CO2.CHO cells stably transfected with human OX2 orexin receptor are cultured in alpha-MEM supplemented with 10% FBS,100 units/mL penicillin G,100 units/mL streptomycin and 400μg/mL geneticin,at 37℃ in an atmosphere of 95% air and 5% CO2.Accumulation of IP1 is measured using IP-One HTRF terbium cryptate-based assay.OX1-CHO cells are seeded into white 384-well plate at the cell density of 1×104 cells per well and cultured for 24h in the presence of 5mM sodium butyrate while OX2-CHO cells are seeded at the cell density of 4×104 cells per well and cultured for 24h in culture medium.After washings Hank's Balanced Salt Solution (HBSS) at room temperature containing 20mM HEPES pH 7.4,50mM,LiCl and 0.1% Bovine Serum Albumin (BSA) cells are pre-incubated for 45 min with antagonist and then treated with agonist for 60 min at 37℃.Detection reagents,IP1-d2 tracer and anti-IP1-cryptate are diluted in lysis buffer and added to the cells.Following 60 min incubation at room temperature,time-resolved fluorescence at 615nm and 665nm are measured with Envision Multilabel flash lamp reader with 100 flashes and 400μs integration time. |

以上为“动物实验计算换算器”的使用方法举例，并不是具体某个试剂的配制，请根据您的实验动物和给药方式选择适当的溶解方案。
计算结果:
工作液浓度： mg/ml；
DMSO母液配制方法： mg 药物溶于 μL DMSO溶液（母液浓度 mg/mL，
体内配方配制方法：取 μL DMSO母液，加入 μL PEG300，混匀澄清后加入μL Tween 80，混匀澄清后加入 μL Saline/PBS/ddH2O，混匀澄清。
1. 首先保证母液是澄清的；
2.
一定要按照顺序依次将溶剂加入，进行下一步操作之前必须保证上一步操作得到的是澄清的溶液，可采用涡旋、超声或水浴加热等物理方法助溶。
