Trigonelline chloride
Based on 10 publication(s) in Google Scholar
Trigonelline chloride is an alkaloid with potential antidiabetic activity that can be isolated from Trigonella foenum-graecum L or Leonurus artemisia. Trigonelline chloride is a potent Nrf2 inhibitor that blocks Nrf2-dependent proteasome activity, thereby enhancing apoptosis in pancreatic cancer cells. Trigonelline chloride also has anti-HSV-1, antibacterial, and antifungal activity, and induces ferroptosis.

In Vitro
It is found that Trigonelline chloride (TG) significantly rescues the morphology of the H9c2 cells. Treatment of cells with Trigonelline chloride attenuates H2O2 induced cell deaths and improves the antioxidant activity. In addition, Trigonelline chloride regulates the apoptotic gene caspase-3, caspase-9 and anti-apoptotic gene Bcl-2, Bcl-XL during H2O2 induced oxidative stress in H9c2 cells. For evident, flow cytometer results also confirm that Trigonelline chloride significantly reduces the H2O2 induced necrosis and apoptosis in H9c2 cells[1].

Trigonelline chloride purchased from MedChemExpress. Usage Cited in: Adv Sci (Weinh). 2024 Mar;11(10):e2305563. [Abstract]
Nrf2 deficiency eliminated the antiferroptotic effect of VDR. Trigonelline (Trig, 100 μM) was pretreated to HG‐cultured HK‐2 cells for 30 min. Western blotting and related densitometric analysis were applied to detect the expression levels of VDR, Nrf2, and HO‐1. β‐actin served as a loading control.

The inhibitor of NRF2 suppressed the protective effect of Ber on cardiomyocytes. Cardiomyocytes were treated with the NRF2 inhibitor trigonelline (TRI) 30 min prior to DOX and Ber stimulation. The levels of cytoplasmic HO-1 and mitochondrial TFAM in cardiomyocytes were measured by Western blotting. Quantitative analysis of the relative protein levels is shown on the right-hand side of the images.
