MRS2279 diammonium 

MRS2279 diammonium is a selective and high affinity P2Y1 receptor antagonist, with a K_i value of 2.5 nM and an IC₅₀ value of 51.6 nM. MRS2279 diammonium competitively inhibits ADP-promoted platelet aggregation with an pK_b value of 8.05^[1][2][3].

MRS2279 diammonium antagonizes 2-MeSADP-stimulated inositol phosphate formation in turkey erythrocyte membranes with a pK_b value of 7.75^[2].
MRS2279 diammonium shows high affinity competitive antagonism to human P2Y1 receptor with a pK_b value of 8.10 in 1321N1 human astrocytoma cells^[2].
MRS2279 diammonium shows specific effect for the P2Y1 receptor, but shows no effect on activation of the human P2Y2, P2Y4, P2Y6, or P2Y11 receptors by their cognate agonists^[2].
MRS2279 diammonium shows no ability to block the capacity of ADP to act through the Gi/adenylyl cyclase linked P2Y receptor of platelets to inhibit cyclic AMP accumulation^[2].
