U-46619 TX A2 Stable Synthetic Analog
Catalog No. 107462
U-46619 is a stable analog of the endoperoxide prostaglandin H2, and a TP receptor agonist. It exhibits properties similar to Thromboxane A2 (TX A2).
Activates TP Receptor
Controls Positive Feedback in Activation and Recruitment of Platelets
Enhances Aggregation by way of other GPCR Receptors
Stimulates AA / TX A2 Production and ADP Secretion
Works on Multiple Species
Induces Acute Pulmonary Hypertension in Animal Models
U-46619 causes platelet shape change and aggregation, and contraction of vascular smooth muscle. Mean EC50 values for shape change in human, rat, and rabbit platelets are 4.8, 6.0, and 7.3 nM respectively, and for platelet aggregation are 82, 145, and 65 nM, respectively.
let activation by U-46619 is mediated largely by ADP released from platelet-dense granules. Polymorphonuclear leukocytes may function as anti-aggregatory agents in platelet aggregation induced by U-46619.
