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.
