Guanylyl Imidodiphosphate trisodium  (Synonyms: Guanosine 5'-[β,γ-imido]triphosphate trisodium)

Guanylyl Imidodiphosphate (Guanosine 5'-[β,γ-imido]triphosphate) trisodium is a non-hydrolysable GTP analogue, an activator of ADP-ribosylation factor (ARF) and a potent stimulator of adenylate cyclase. Imidodiphosphate trisodium can be used in protein synthesis studies^[1][2][3].

Guanylyl Imidodiphosphate trisodium (GppNHp) (100 μM) induces the secretion of dense granules from permeabilized platelets in response to calcium ion stimulation, and GTP-Ral enhances the calcium sensitivity of permeabilized platelet dense granule secretion which is inhibited by Sec5-RBD^[1].
Guanylyl Imidodiphosphate trisodium (GppNHp) (0.017-333 μM) causes a significant reduction in the lag time required to stimulate adenylate cyclase activity^[3].
