Biological Activity

Inhibitor of Cav3.2 channels (IC50 = 6.5 μM); displays no effect on Cav3.1 or Cav3.3 channels heterologously expressed in HEK 293 cells. Also enhances the generation of induced pluripotent stem cells (iPSCs) from mouse and human somatic cells by increasing reprogramming efficiency. Naturally occurring antioxidant.

Technical Data

Soluble to 500 mM in water and to 100 mM in DMSO
>99 %
Store at RT
