What is "adenophostin"

Adenophostin A is a potent inositol triphosphate (IP) receptor agonist, but is much more potent than IP.

IPR3 is a ligand-gated intracellular Ca release channel that plays a central role in modulating cytoplasmic free Ca concentration (Cai). Adenophostin A is structurally different from IP but could elicit distinct calcium signals in cells.
