General description
A macrocyclic bis-1-oxaquinolizidine natural product isolated from a marine sponge. A very potent, reversible and membrane-permeable blocker of IP3-mediated Ca2+ release (IC50 = 358 nM) that does not interact with the IP3-binding site. Displays high selectivity over the skeletal isoform of the ryanodine receptor type 1 (Ry1R). Also blocks bradykinin- and carbamylcholine-induced Ca2+ efflux from the ER stores in a reversible manner.
