    Capsazepine purchased from MCE. Usage Cited in: Food Funct. 2018 Jan 24;9(1):344-354.  [Abstract]

    Capsaicin-induced decrease in the expression of MMP-9 and Twist1 is restored by Capsazepine (CPZ). The protein levels of MMP-9 and Twist1 were determined by western blotting. Actin is used as a loading control.

    生物活性

    Capsazepine is a synthetic analogue of the sensory neurone excitotoxin, and an antagonist of TRPV1 receptor with an IC50 of 562 nM.

    IC50 & Target

    TRPV1 receptor[1]

    体外研究
    (In Vitro)

    Capsazepine (50 μM) optimally enhances the upregulation of (death receptors) DRs without affecting cell viability HCT116 cells. Capsazepine (30-50 μM) induces ROS generation and ROS mediate Capsazepine-induced DR5 upregulation in HCT116 cells[1]. Capsazepine (1-100 μM, 45 min preincubation) inhibits the evoked CGRP-LI release. Capsazepine (3-100 μM) prevents low pH- and capsaicin-induced CGRP-LI release from rat soleus muscle at concentrations which do not affect the release evoked by KCl. Capsazepine (3-100 μM, without 10 μM) produces a nonspecific inhibitory effect on CGRP-LI release from peripheral endings of the capsaicin-sensitive primary afferent neurone[2].

    体内研究
    (In Vivo)

    Capsazepine (15 mg/kg, s.c.) prevents the increase in respiratory system resistance and decreases the increase in tissue damping during endotoxemia. Capsazepine attenuates lung injury evidenced by reduction on collapsed area of the lung parenchyma induced by LPS[3].

    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: ≥ 5 mg/mL (13.27 mM); 澄清溶液

      此方案可获得 ≥ 5 mg/mL(饱和度未知)的澄清溶液。

      1 mL 工作液为例,取 100 μL 50.0 mg/mL 的澄清 DMSO 储备液加到 400 μL PEG300 中,混合均匀;再向上述体系中加入 50 μL Tween-80,混合均匀;然后再继续加入 450 μL 生理盐水 定容至 1 mL

      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

    Cell Assay
    [1]

    To assay intracellular ROS, HCT116 cells are preincubated with 20 μM dichlorofluorescein diacetate (DCF DA) for 15 min at 37°C and then treated with Capsazepine. After 1 h of incubation, the increase in fluorescence resulting from the oxidation of DCF DA to DCF is measured by flow cytometry. The mean fluorescence intensity at 530 nm is calculated for at least 10,000 cells at a flow rate of 250-300 cells/s.

    MCE has not independently confirmed the accuracy of these methods. They are for reference only.

    Animal Administration
    [3]

    To verify the role of TRPV1 on lung mechanics during LPS-induced ALI, the animals (n = 10 per group) are pre-treated with vehicle or Capsazepine (15 mg/kg; s.c.), then receive saline or LPS (5 mg/kg, i.p.) after 10 min. Thus, the mice are randomly divided into four groups with 10 mice in each group: (i) control (vehicle + saline), (ii) Capsazepine + saline, (iii) vehicle + LPS and (iv) Capsazepine + LPS. After a 24-hr treatment with saline or LPS, the mice are anaesthetized and paralysed and lung mechanics function is evaluated. Afterwards, the lungs are removed for histology.

    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.
