Biological Activity

Calpain inhibitor (IC50 = 0.09 μM) that activates p53-dependent apoptosis in tumor cell lines. Increases activated p53, p21 and caspase levels and promotes cell cycle arrest through inhibition of cyclin D degradation in vitro. Also attenuates ischemia/reperfusion injury in cardiomyocytes, hepatocytes and renal tubular cells through downregulation of iNOS and COX-2 expression.

Apoptosis

Apoptosis Signaling Pathway

Apoptosis is a physiological process for cell death that is critical during aging and development. It may also be referred to as cell 'suicide'. Apoptosis can be triggered by events both inside and outside of the cell.
