  Dual Effect of Nucleotides on P2Y Receptors

  摘要：

  The interaction of ADP, 2MeSADP, and ADP betaS with the adenine nucleotide receptor P2Y(1) in the hP2Y(1)-1321N1 cell line and of UDP with a receptor or receptors recognizing pyrimidine nucleotides in NG108-15 cells was studied over a wide range of ligand concentrations, Bell-shaped dose-response curves for stimulation of phosphoinositide hydrolysis were obtained in these cells, This dual behavior of the agonists studied was characterized by two dissociation constants, K-agon and K-antag, which quantify the agonistic and antagonistic activity of these ligands and can be compared with the conventional EC50 and IC50 values, respectively. The data revealed a common pattern of agonistic and antagonistic behavior of nucleoside diphosphates and their derivatives at these two types of P2Y receptors, pointing to some similar properties of their nucleotide binding sites.
