生物活性

Pexacerfont is a selective corticotropin-releasing factor (CRF1) receptor antagonist with IC50 of 6.1±0.6 nM for human CRF1 receptor.

IC50 & Target

IC50: 6.1±0.6 nM (human CRF1 receptor)[1]
体外研究
(In Vitro)

Pexacerfont demonstrates a potent and specific inhibitory effect (IC50=6.1 ± 0.6 nM) toward human CRF1 receptor and has greater than 1000-fold lower affinity (IC50>1000 nM) for the CRF-binding protein and biogenic amine receptors[1].

体内研究
(In Vivo)

Pexacerfont (BMS-562086) is active in rats (1-10 mg/kg, orally) in the defensive withdrawal and elevated plus maze models of anxiety. After the intravenous bolus dose, the plasma Pexacerfont concentrations exhibited a multiexponential decline in rats, dogs, and chimpanzees. The CLp of Pexacerfont was higher in rats (17.9 mL/kg per min) and dogs (11.6 mL/kg per min) than in chimpanzees (2.0 mL/kg per min). Assuming the value of CLp of Pexacerfont approximates the value of CLb in these three species, Pexacerfont has an estimated hepatic extraction ratio of 0.32, 0.38, and 0.08 in rats, dogs, and chimpanzees, respectively (calculated by dividing CLp by respective hepatic blood flow, 55.2, 30.9, and 25.5 mL/kg per min for rats, dogs, and chimpanzees). The assumption that CLb is equal to CLp is reasonable at least in rats, where the blood to plasma concentration ratio of BMS-562086-equivalent radioactivity was 0.95 at 1 h postdose[1].

动物实验：

请根据您的 实验动物和给药方式 选择适当的溶解方案。

以下溶解方案都请先按照 In Vitro 方式配制澄清的储备液，再依次添加助溶剂：
——为保证实验结果的可靠性，澄清的储备液可以根据储存条件，适当保存；体内实验的工作液，建议您现用现配，当天使用；
以下溶剂前显示的百分比是指该溶剂在您配制终溶液中的体积占比；如在配制过程中出现沉淀、析出现象，可以通过加热和/或超声的方式助溶

  • 方案 一

    请依序添加每种溶剂： 10% DMSO    40% PEG300    5% Tween-80    45% Saline

    Solubility: ≥ 2.5 mg/mL (7.34 mM); 澄清溶液

    此方案可获得 ≥ 2.5 mg/mL（饱和度未知）的澄清溶液。

    生理盐水的配制：将 0.9 g 氯化钠，溶解于 ddH₂O 并定容至 100 mL，可以得到澄清透明的生理盐水溶液。
  • 方案 二

    请依序添加每种溶剂： 10% DMSO    90% (20% SBE-β-CD in Saline)

    Solubility: ≥ 2.5 mg/mL (7.34 mM); 澄清溶液

    此方案可获得 ≥ 2.5 mg/mL（饱和度未知）的澄清溶液。

    以 1 mL 工作液为例，取 100 μL 25.0 mg/mL 的澄清 DMSO 储备液加到 900 μL 20% 的 SBE-β-CD 生理盐水水溶液 中，混合均匀。

    20% SBE-β-CD in Saline 的配制（4°C，储存一周）：2 g SBE-β-CD（磺丁基醚 β-环糊精）粉末定容于 10 mL 的生理盐水中，完全溶解至澄清透明。

Cell Assay
[1]

Caco-2 cells at passage 50 to 60 are seeded on polycarbonate membranes of 24 well Transwell plates at a density of 60,000 cells/cm2. The cells are cultured for 21 to 25 days in culture medium consisting of Dulbecco's modified Eagle's medium supplemented with 10% fetal bovine serum, 0.5 mM HEPES, 1% nonessential amino acids, 1% L-glutamine, 100 U/mL penicillin-G, and 100 μg/mL streptomycin. Before the permeability studies, apical (AP) and basolateral (BL) media are replaced with transport buffer (Hanks' balanced salt solution supplemented with 2% N, N-dimethylacetamide, pH 7.4). AP to BL permeability study is initiated by replacing the AP medium with the transport buffer containing 25 μM BMS-562086. All permeability experiments are performed at 37°C.Transepithelial electrical resistance (TEER) values are measured to assess cell monolayer integrity. TEER values are obtained both at the beginning and at the end of each experiment. Only wells with TEER values between 400 and 500 Ω/cm2 throughout the experiment are used in the studies. Mannitol (25 or 100 μM) transport experiments are performed in the same manner as other transport experiments. Mannitol served as a probe of the Caco-2 cell monolayer integrity[1].

Animal Administration
[1]

Rats[1]
One group of male Sprague-Dawley rats (n=3, 0.34-0.35 kg b.wt.) instrumented with single jugular vein cannulas are designated for oral administration, and a second group of male Sprague-Dawley rats (n=3, 0.34-0.35 kg b.wt.) instrumented with dual jugular vein cannulas are designated for intravenous administration. All rats are fasted for approximately 18 h before use and for 4 h after dosing. Water is provided ad libitum. Pexacerfont (BMS-562086) is administered orally by gavage to three rats at a single dose of 5 mg/kg in 0.5% aqueous methylcellulose. A single intravenous bolus dose of Pexacerfont is administered to three rats at 1 mg/kg in 20% ethanol in saline via the jugular vein cannula. Blood samples (0.2 mL/time point per animal) are collected via the jugular vein cannula for analysis of Pexacerfont at 0, 0.08 (intravenous dose only), 0.17 (intravenous dose only), 0.25, 0.5, 0.75, 1, 2, 4, 8, 12, 24, 48, 72, and 96 h postdose. Plasma is prepared from the blood samples by centrifuging for 10 min at 1000g and 5°C.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
