Catalog Number: 2159
Chemical Name: (1R*,2S*)-4-[2-Iodo-6-(methylamino)-9H-purin-9-yl]-2-(phosphonooxy)bicyclo[3.1.0]hexane-1-methanol dihydrogen phosphate ester tetraammonium salt
Biological Activity
Highly potent and selective antagonist of the platelet P2Y1 receptor (Ki = 0.78 nM). Inhibits ADP-induced aggregation of human platelets with an IC50 value of 0.95 nM. Inhibits the upregulation of NTPDase1 by ATPγS. Prevents thrombus formation in vivo.
