title: The effects of an ASA-like hydroperoxide compound on adenosine diphosphate induced platelet aggregation.
abstract: A hydroperoxide compound structurally related to acetylsalicylic acid, 3-hydroperoxy-3-methylphthalide, inhibits both the first and second phases of adenosine diphosphate induced, biphasic, human platelet aggregation. This occurs over the same concentration range (0.05-0.5 mM) that acetylsalicylic acid inhibits second phase aggregation and the release reaction only. The complete inhibition of adenosine diphosphate induced aggregation is a unique pharmacological property for an acetylsalicylic-acid-like compound.
