Eptifibatide Acetate

Cell lines

Activated platelets and leukocytes

Preparation method

The solubility of this compound in DMSO is >28.7 mg/mL. General tips for obtaining a higher concentration: Please warm the tube at 37 ℃ for 10 minutes and/or shake it in the ultrasonic bath for a while. Stock solution can be stored below -20℃ for several months.

Reacting condition

0.0625-1.5 w g/ml

Applications

Eptifibatide dose-dependently enhanced (0.0625-1.5 w g/ml) both collagen-induced platelet-monocyte (P/M) formation and monocyte TF expression with maximum enhancement about 60 and 120%, respectively, at 0.5 w g/ml eptifibatide. Eptifibatide had only a minor effect on platelet-neutrophil (P/N) formation and no effect on neutrophil TF expression. Eptifibatide dose-dependently reduced ADP, collagen, and thrombin-induced platelet aggregation (IC50 = 16-27 mg/mL), dense granule secretion (IC50 = 22-31 mg/mL) and lysosome secretion (IC50 = 25-50 mg/mL). Eptifibatide (8 mg/mL) together with bivalirudin (70 ng/mL, a direct thrombin inhibitor) effectively (approximately 90%) reduced platelet aggregation induced by thrombin (0.2 U/mL).

Other notes

Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal.
