Bivalirudin Bivalirudin Bivalirudin (Angiomax or Angiox, manufactured by The Medicines Company) is a direct thrombin inhibitor (DTI). Chemically, it is a synthetic congener of the naturally occurring drug hirudin (found in the saliva of the medicinal leech "Hirudo medicinalis"). Bivalirudin is a DTI that overcomes many limitations seen with indirect thrombin inhibitors, such as heparin. Bivalirudin is a short, synthetic peptide. It is a potent and highly specific inhibitor of thrombin. It inhibits both circulating and clot-bound thrombin, while also inhibiting thrombin-mediated platelet activation and aggregation. Bivalirudin has a quick onset of action and a short half-life. It does not bind
Formyl peptide receptor 3 derived from the N-terminal sequence of heme-binding protein 1 by cathepsin D cleavage that potently stimulates chemotaxis through FPR3 in monocytes and monocyte-derived dendritic cells. F2L thereby may be a pro-inflammatory stimulus for FPR3. Similar to FPR2 (see FPR2 section), FPR3 is activated by humanin and thereby may be involved in inhibiting the inflammation occurring in and perhaps contributing to Alzheimer's disease. Formyl peptide receptor 3 N-formyl peptide receptor 3 (FPR3) is a receptor protein that in humans is encoded by the "FPR3" gene. Confusingly, there are two nomenclatures for FPR receptors and their genes, the first one used, FPR,
