Description

Xestospongins and araguspongins are marine natural products first isolated from Pacific basin sponges, and noted to have vasodilatory properties.¹ Inositol phosphates (IP) are important signal transduction messengers acting via IP₃ receptors to promote the mobilization of Ca2+ from intracellular stores.² Araguspongin B antagonizes the calcium-releasing action of inositol 1,4,5-triphosphate at the receptor level in cerebral microsomes, with an IC₅₀ of 0.6 µM.³ It is nearly as potent as xestospongin C as an antagonist of the IP₃ receptor.
