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 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.

Diadenosine pentaphosphate pentasodium is an endogenous vasoactive purine dinucleotide isolated from thrombocytes. Diadenosine pentaphosphate pentasodium is a component of secretory vesicles in platelets, chromaffin cells, Torpedo synaptic terminals, and brain synaptosomes. Diadenosine pentaphosphate pentasodium is therefore used in purinergic signaling research systems to investigate nucleotide-mediated vascular regulation, neurotransmission processes, and intracellular vesicular signaling mechanisms in physiological models.

Ap5A (Diadenosine pentaphosphate) is a polyphosphate diadenosine compound that functions as an adenylate kinase inhibitor, with a Ki value of 2.5 nM. This compound is applicable in cancer research.

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.
