Zomepirac
Zomepirac (McN-2783-21-98 free acid) is an orally active prostaglandin synthetase inhibitor. Zomepirac blocks prostaglandin synthesis and inhibits Collagen (HY-P72147)- or Epinephrine (HY-B0447)-induced platelet aggregation. Zomepirac can be used for the research of postoperative pain and osteoarthritis.

Biological Activity
Zomepirac potently inhibits prostaglandin synthesis in homogenised bovine seminal vesicles[3].
Zomepirac potently inhibits Collagen (HY-NP003)-induced aggregation of human platelets in vitro[3].
Zomepirac (0.1-10 μg/mL) is 98.5% bound to human plasma albumin in vitro[3].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
