生物活性

Pridopidine, a dopamine (DA) stabilizer, acts as a low affinity dopamine D2 receptor (D2R) antagonist. Pridopidine exerts high affinity towards sigma 1 receptor (S1R) with Ki between 70 and 80 nM, which is ~100× higher than its affinity toward D2R.

IC50 & Target

D2 Receptor

 

体外研究
(In Vitro)

Pridopidine 是一种多巴胺 (DA) 稳定剂, 对亨廷顿病 (HD) 具有神经保护作用。为了阐明 Pridopidine 的神经保护功效并探索潜在的分子机制,评估了 Pridopidine 保护细胞免于凋亡并最终激活促生存靶标的能力。最有效剂量 Pridopidine (150 μM) 可显著减少表达内源水平突变 Htt (STHdh111/111) 的永生化纹状体敲入细胞的细胞凋亡,并显著增强促存活激酶的磷酸化状态ERK[2]

  • 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 (8.88 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。

    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。

Cell Assay
[2]

Conditionally immortalized mouse striatal knock-in cells expressing endogenous levels of wild-type (STHdh7/7) or mHtt (STHdh111/111) are used. Different concentrations of Pridopidine (100, 150, 200 and 300 μM) are tested to investigate the anti-apoptotic effect of the molecule on immortalized cells cultured in serum-free medium at 39°C for six hours. In NE100 experiments, cells are pre-incubated with the compound (10 μM) for 2 hrs before culturing them in apoptotic conditions. At the end of each treatment, cells are collected and incubated with FITC-conjugated Annexin V. Fluorescence Activated Cell Sorting (FACS) analysis is performed[2].

Animal Administration
[1][2]

Rats[1]
Sprague Dawley (SD) male rats (n=6 per group) are treated daily by oral gavage with Pridopidine at a dose of 60 mg/kg or vehicle (water) over the course of 10 days. On day 10, 90 min following last drug/water administration, brains are removed, and quickly rinsed with cold physiological saline. The striatum of the left hemisphere is gently extracted and immediately immerged in 1000 µL of RNAlater Solution in pre-labelled polypropylene vials and stored at 4°C overnight (to allow the solution to thoroughly penetrate the tissue), then moved to -20°C until analysis. RNA is isolated from the striatum of each rat and analysed[1].
Mice[2]
All in vivo experiments are conducted in R6/2 transgenic mice expressing exon 1 of human Htt with approximately 160±10 (CAG) repeats and manifesting first symptoms around week 7, and in wild-type (WT) littermates maintained on the B6CBA strain. Animals are housed singly and maintained under a 12-hr light/dark cycle environment in a clean facility and given free access to food pellets and water. Pridopidine is dissolved in saline (vehicle), and administered daily by intraperitoneal (i.p.) injection at a dose of 5 or 6 mg/kg per bodyweight during the light phase of the circadian rhythm. Control mice (WT and R6/2) are injected daily with the same volume of vehicle. All the mice are singly housed in home cage. Pridopidine (5 mg/kg) is administered to pre-symptomatic mice starting at week 5 to week 11 (6 week duration) and for symptomatic animals starting from week 7 to week 9 (3 weeks duration) and 1 week of daily administration (6 mg/kg) at week 10[2].

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.
