Should you need adjustments to this formulation, contact our sales team for custom testing.	0.15mg/ml (0.34mM)	Taking the 1 mL working solution as an example, add 50 μL of 3 mg/ml clarified DMSO stock solution to 400 μL of PEG300, mix evenly to clarify it; add 50 μL of Tween80 to the above system, mix evenly to clarify; then continue to add 500 μL of ddH2O to adjust the volume to 1 mL. The mixed solution should be used immediately for optimal results.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.

Mechanism of Action

Targets/IC₅₀/Ki	GPIIb/IIIa
In vitro	Tirofiban (MK-383, Aggrastat) is a nonpeptide derivative of tyrosine that selectively inhibits the GP-IIb/IIIa receptor, with minimal effects on the ɑvβ3 vitronectin receptor. This compound inhibits platelet aggregation of gel-filtered platelets induced by 10 μM ADP with IC50 of 9 nM, but the IC50 for inhibition of human umbilical vein adhesion to vitronectin, which depends on ɑvβ3 vitronectin receptors, is 62 μmol/L.
In vivo	Tirofiban (10 to 500 mg/kg or 360-min continuous i.v. infusions of 1 to 10 micrograms/kg/min) inhibits platelet aggregation responses to ADP and collagen in canine models. When administered to humans at 0.15μg/kg/min for 4 h, this compound produced a 2.5-fold increase in bleeding time and 97% inhibition of ADP-induced platelet aggregation.
