生物活性

Trigonelline is an alkaloid with potential antidiabetic activity that can be isolated from Trigonella foenum-graecum L or Leonurus artemisia. Trigonelline is a potent Nrf2 inhibitor that blocks Nrf2-dependent proteasome activity, thereby enhancing apoptosis in pancreatic cancer cells. Trigonelline also has anti-HSV-1, antibacterial, and antifungal activity and induces ferroptosis.

Human Endogenous Metabolite

 

体外研究
(In Vitro)

Trigonelline 显著恢复 H9c2 细胞的形态。用 Trigonelline 处理细胞可减弱 H2O2 诱导的细胞死亡并提高抗氧化活性。 此外,Trigonelline 在 H2O2 诱导的 H9c2 细胞氧化应激过程中调节凋亡基因 caspase-3、caspase-9 和抗凋亡基因 Bcl-2、Bcl-XL。显然,流式细胞仪结果也证实 Trigonelline 显著降低 H2O2 诱导的 H9c2 细胞坏死和凋亡[1]

体内研究
(In Vivo)

Trigonelline 在 Streptozotocin 诱导的糖尿病大鼠中降低骨矿化并趋于恶化骨机械性能。 在 Nicotinamide/Streptozotocin 处理的大鼠中,Trigonelline 显著增加骨矿物质密度 (BMD),并倾向于提高松质骨强度。 Trigonelline 不同地影响患有 Streptozotocin 诱导的代谢紊乱大鼠的骨骼系统,加剧 Streptozotocin 处理大鼠的骨质疏松变化,并对非高血糖 (Nicotinamide/Streptozotocin 处理) 大鼠的骨骼产生有利影响[2]

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: ≥ 0.71 mg/mL (5.18 mM); 澄清溶液

    Solubility: ≥ 0.71 mg/mL (5.18 mM); 澄清溶液

    此方案可获得 ≥ 0.71 mg/mL(饱和度未知)的澄清溶液。

    1 mL 工作液为例,取 100 μL 7.1 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

The H9c2 cells are seeded in the 96 well at a density of 1×105 cells/well. The cells are treated with different concentrations of Trigonelline (TG) (25 to 150 μM) and hydrogen peroxide (25 to 125 μM). It is incubated at 37°C in 5% CO2 incubator for 24 h and 6 h respectively and then the culture is treated with the water soluble tetrazolium (WST) reagent incubated for 2 h to 4 h. The living cells absorb the WST then it is converted into an orange colour product. Then, the intensity of colour is measured at 450 nm using spectra count ELISA reader. For cardio protective activity, the cells are seeded and separated into six groups control, H2O2 alone, the rest of groups’ initially exposed to different concentration (25 to 125 μM) of Trigonelline for 48 hours. Then, 100 μM of H2O2 is added and incubated for 4 hours, after, read the absorbance at 450 nm for cell viability assay[1].

Animal Administration
[2]

Three-month-old female Wistar rats are used in this study. The animals are divided into five groups (n=10): Control rats, Streptozotocin-treated control rats, Streptozotocin-treated rats receiving Trigonelline (50 mg/kg p.o. daily), Nicotinamide/streptozotocin-treated control rats, and Nicotinamide/streptozotocin-treated rats receiving Trigonelline (50 mg/kg p.o. daily). Administration of Trigonelline starts two weeks after streptozotocin and lasts four weeks. Trigonelline is administered once daily by a stomach tube. All control rats receive tap water (the vehicle) at the same volume of 2 mL/kg p.o. The four-week period of Trigonelline administration is long enough to demonstrate skeletal effects of Trigonelline and other compounds of plant origin in rats. The rats are fasted overnight after the last Trigonelline or vehicle administration. The next day, the blood glucose level is measured and the rats are anesthetized with ketamine and xylazine, and then sacrificed by cardiac exsanguination[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.
