The antithrombotic properties of 3-DSC were assessed through various methods, including tests for clotting times, platelet aggregation analysis, evaluation of factor Xa activity and production, nitric oxide levels, and the expression of related proteins. This study found that 3-DSC extended the clotting time in human platelet-poor plasma at levels comparable to rivaroxaban, a standard anticoagulant, and reduced platelet aggregation triggered by ADP or the thromboxane A2 analog U46619. Additionally, 3-DSC suppressed the phosphorylation of PLCγ2 and PKC, as well as intracellular calcium release, which are essential for platelet aggregation. It also decreased the expression of adhesion molecules P-selectin and PAC-1. Furthermore, 3-DSC promoted nitric oxide production while reducing endothelin-1 secretion in endothelial cells exposed to ADP or U46619. Lastly, it inhibited both the activity and production of coagulation factor Xa in endothelial cells and prevented activated factor X (FXa)-induced platelet aggregation. Injection of 3-DSC significantly shortened the time required for thrombus resolution, reduced the size and number of thrombi, and decreased mortality in mouse models of thromboembolism. The study demonstrates that 3-DSC effectively exhibits antithrombotic activity by prolonging the clotting time, inhibiting platelet aggregation, and reducing factor Xa activity, comparable to standard anticoagulants.
