diadenosine

Diadenosine pentaphosphate pentaammonium, an endogenous vasoactive purine dinucleotide isolated from thrombocytes, is one component of the diadenosine polyphosphates (ApnA, n=2-7) family. These compounds are found in secretory vesicles, including those in platelets, chromaffin cells, Torpedo synaptic terminals, and brain synaptosomes[1][2].

Diadenosine pentaphosphate pentasodium, an endogenous vasoactive purine dinucleotide isolated from thrombocytes, serves as a key component of secretory vesicles in platelets, chromaffin cells, Torpedo synaptic terminals, and brain synaptosomes. This compound, along with other diadenosine polyphosphates (ApnA, n=2-7), plays a crucial role in physiological processes[1][2].

Diadenosine pentaphosphate pentalithium is an endogenous vasoactive purine dinucleotide, isolated from thrombocytes. It is a member of the diadenosine polyphosphates (ApnA, n=2–7) and is found in secretory vesicles of platelets, chromaffin cells, Torpedo synaptic terminals, and brain synaptosomes.

8Br-HA is an inhibitor of fragile histidine triad diadenosine triphosphatase (FHIT; IC50= 0.12 μM).1It inhibits the growth of HCC827 and H460 lung cancer cells (GI50s = 0.87 and 5.9 μM, respectively). 1.Kawaguchi, M., Sekimoto, E., Ohta, Y., et al.Synthesis of fluorescent probes targeting tumor-suppressor protein FHIT and Identification of apoptosis-inducing FHIT inhibitorsJ.
