Biological Data Biological description Cx43 hemichannel blocker. Inhibits astroglial Cx43 hemichannels in a dose-dependent manner, without affecting gap junction channels and reduces mitochondrial potassium influx. Also reduces intracellular ROS generation, cell death, inflammation and premature cell senescence.
