Discontinued Product
This product has been withdrawn from sale and is superseded by MRS 2500 tetraammonium salt (Cat. No. 2159)
Description: Selective, high affinity P2Y1 antagonist
Chemical Name: (1R*,2S*)-4-[2-Chloro-6-(methylamino)-9H-purin-9-yl]-2-(phosphonooxy)bicyclo[3.1.0]hexane-1-methanol dihydrogen phosphate ester diammonium salt
Purity: ≥98% (HPLC)
Biological Activity for MRS 2279
MRS 2279 is a selective, high affinity competitive antagonist of the P2Y1 receptor (Ki = 2.5 nM; IC50 = 51.6 nM). Fails to block nucleotide signaling at most other P2Y receptors (P2Y2, P2Y4, P2Y6, P2Y11 and P2Y12) and potently inhibits ADP-induced aggregation of human blood platelets in vitro (pKB = 8.05).
