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. Does not interact with the IP3 binding site. Recently shown to be an ineffective antagonist of IP3-evoked Ca2+ release in IP3 receptor expressing DT40 cells. Cell permeable.

Used in inhibitor cocktail

Blocker of IP3 channels
By Sergiy Sylantyev on 05/19/2019
Application: Species: Rat

We used (-)-Xestospongin C (XeC) to block calcium release from endoplasmic reticulum via IP3 channels in presynaptic neurons. As a result, LPI, agonist of GPR55 receptor, failed to induce an increase of neurotransmitter release, since this process is calcium-dependent. As a sequence, after application of XeC there was no augmentation of the amplitude of evoked post-synaptic response in postsynaptic neuron: see image.
