Formulários:
Agonistic ligand, mainly for nucleoside receptor A₁
Nucleoside-triphosphates can be converted by different membrane-bound phosphatases into nucleosides acting as nucleoside receptor ligands. The ester form is protected during uptake and transport and can be well-directed released through activation.

Specific Ligands:

Ligand for purinergic receptors:
P2X1, P2X2[1]

Antagonist for purinergic receptors:
P2X1[2,3], P2X3[3,6], P2X4[4], P2X[5,7]
