Biological Activity

(-)-Xestospongin C is a reported inhibitor of IP3-dependent Ca2+ release. Inhibits bradykinin-induced Ca2+ release in PC12 cells and attenuates PHP-induced IL-2 production in Jurkat T cells. Exhibits no effect on ryanodine receptor-mediated Ca2+ release in PC12 cells and shows no apparent interaction with the IP3 binding site. Other subsequent reports show (-)-Xestospongin C to be ineffective as an antagonist of IP3-evoked Ca2+ release in IP3 recepto- expressing DT40 cells. Cell permeable.

NOTE: (-)-Xestospongin C is typically used at a final concentration ranging from 0.5 to 10 μM. It is recommended to prepare stock solutions (10x to 100x) in DMSO or ethanol.
