title: Structure-activity relationships for selected sulfur-rich antithrombotic compounds.
abstract: We assessed the antithrombotic activity of some simple organosulfur compounds which have some of the functionality found in the disulfide ajoene, a pharmacologically active compound isolated from garlic. The results establish that antithrombotic activity is associated with disulfides directly attached to a phenyl ring and is further enhanced by an alpha-sulfonyl group. CH(3)SO(2)CH(2)SSPh proved to be a potent inhibitor of platelet aggregation with an IC(50) of 5 microM.
