Xestospongins 和 araguspongins 都是从太平洋盆地海绵中首次分离出来的海洋天然产物,具有血管扩张特性。肌醇磷酸 (IP) 是重要的信号转导信使,它通过 IP3 受体起作用,促进 Ca2+ 从细胞内储存中动员。Araguspongin B 在脑微粒体的受体水平上拮抗肌醇 1,4,5-三磷酸的钙释放作用,IC50 为 0.6 μM。作为 IP3 受体拮抗剂,它的效力几乎与 xestospongin C 一样强。

生物活性

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-trisphosphate at the receptor level in cerebral microsomes, with an IC50 of 0.6 μM. It is nearly as potent as xestospongin C as an antagonist of the IP3 receptor.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
