Biological Data

Biological description Cx43 hemichannel blocker. Shows no effect on gap junction coupling or at Panx-1 channels. Reduces mitochondrial potassium influx in cardiomyocytes and reduces infact size in a mouse ischemia model. Inhibits astroglial Cx43 hemichannels in a dose-dependent manner, without affecting gap junction channels.
