Biological Activity for A23187, free acid

A23187, free acid is a calcium ionophore that induces Ca²⁺-dependent cell death by increasing intracellular calcium concentration. Promotes intracelllular ROS generation and platelet particle formation (fragmentation) in vitro and in vivo. Can be used to induce autophagy in mammalian cells.
