General description

Synthetic form of the macrocyclic bis-1-oxaquinolizidine isolated from the Okanowan marine sponge.

Biochem/physiol Actions

Xestospongin C is a selective, reversible and membrane-permeable inhibitor of IP3 receptor. Reversibly blocks bradykinin- and carbamylcholine- Ca2+ efflux from the endoplasmic reticulum stores.
