1 Although the platelet ADP receptor is thought to exhibit a high degree of structural selectivity, adenosine 5"-O-(thiotriphosphate) (ATP alpha S) is a potent inhibitor of ADP-induced platelet activation and has been recently shown to bind with high affinity (Kd 3 +/- 0.1 nM) to formaldehyde-fixed platelets and to be photoincorporated into an 18-kDa fragment beginning at Tyr-198 of glycoprotein (GP) IIb alpha (Greco, N.
