Uses
2′(3′)-O-(4-Benzoylbenzoyl)adenosine 5′-triphosphate triethylammonium salt has been used as a P2X4 receptor agonist in rat kidney sections, type I diabetes induced rats and astrocyte?neuron coculture. It has also been used as a synthetic ATP analog in isotonic E3 medium.
General Description
2′(3′)-O-(4-Benzoylbenzoyl)adenosine 5′-triphosphate is a photoreactive analog of ATP.
Biological Activity
Prototypic P2X 7 receptor agonist that exhibits 5 - 10 fold greater potency than ATP (EC 50 = 0.7 μ M in HEK 293 cells). Exhibits partial agonist activity at P2X 1 (pEC 50 = 8.7) and P2Y 1 receptors and can be used as a photoaffinity label for ATPase.
Biochem/physiol Actions
2′(3′)-O-(4-Benzoylbenzoyl)adenosine 5′-triphosphate triethylammonium salt is a selective purinergic receptor (P2X) agonist. It is more potent than ATP at homodimeric P2X7 receptors. It also effectively activates P2X1, P2X2, and P2X3 receptors. Useful as a photoaffinity label for proteins and enzymes that bind ATP.
