说明

一般說明

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.
