Trigonelline-d3-1 chloride (Trigonelline-d3-1 hydrochloride) is the deuterium labeled Trigonelline chloride (HY-N0415). 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.
