Adenophostin
# Adenophostin

Adenophostin A is a potent inositol trisphosphate $(IP_3)$ receptor agonist, but is much more potent than $IP_3.$

$IP_3R$ is a ligand-gated intracellular $Ca^{2+}$ release channel that plays a central role in modulating cytoplasmic free $Ca^{2+}$ concentration $(Ca^{2+}i).$ Adenophostin A is structurally different from $IP_3$ but could elicit distinct calcium signals in cells.
