NF157 significantly decreases the expression of metalloproteinase (MMP)-3, MMP-13, which can be used in the treatment of osteoarthritis (OA). NF157 is a highly selective nanomolar P2Y11 antagonist (pKi: 7.35). The IC50s are 463 nM, 1811 µM, 170 µM for P2Y
MRS2698 is an effective and highly selective agonist of the P2Y2 receptor (EC50: 8 nM). MRS2698 also is >300-fold P2Y2-selective versus the P2Y4 and P2Y6 receptors.
MRS2179 is a competitive P2Y1 receptor antagonist (Kb = 100 nM) with no appreciable activity at P2Y2, P2Y4, or P2Y6 at concentrations up to 30 µM, or at P2Y12 and P2Y13. It inhibits ADP-induced platelet shape change and aggregation (pA2 = 6.55) in vitro a
