MRS 2279

MRS 2279 is a selective P2Y1 antagonist with high affinity and results in modulation of aggregation of blood platelets induced by ADP.

Selective, high affinity competitive antagonist of the P2Y 1 receptor (K i = 2.5 nM; IC 50 = 51.6 nM). Fails to block nucleotide signaling at most other P2Y receptors (P2Y 2 , P2Y 4 , P2Y 6 , P2Y 11 and P2Y 12 ) and potently inhibits ADP-induced aggregation of human blood platelets in vitro (pK B = 8.05).
