Adenophostin

Adenophostin (molecular name C16H20N5O18P 3 ) is a potent Inositol 1,4,5 triphosphate (IP3) receptor agonist, but is much more potent than IP3.

IPR3 is a ligand-gated intracellular Ca2+ release channel that plays a central role in modulating cytoplasmic free Ca2+ concentration (Ca2+i). Adenophostin A is structurally different from IP3 but could elicit distinct calcium signals in cells.
