Tirofiban
Based on 6 publication(s) in Google Scholar
Tirofiban (L700462) is a selective and reversible platelet integrin receptor (Gp IIb/IIIa) antagonist that inhibits fibrinogen binding to this receptor and has antithrombotic activity. Tirofiban induces proliferation and migration on endothelial cell by inducing production of VEGF. Tirofiban can significantly reduces myocardial no-reflow and ischemia-reperfusion injury by alleviating myocardial microvascular structural and endothelial dysfunction in the ischemic area.

Anti-aggregation efficiency of single-drug combinations for platelets in the combinatorial screening tests for Volunteer 1. For Aspirin (Asp), the concentrations were 2 μM, 4 μM (2 μM + 2 μM), 20 μM, 22 μM (2 μM + 20 μM), and 40 μM (20 μM + 20 μM). For Tirofiban (Tif), the concentrations were 0.2 μM, 0.4 μM (0.2 μM + 0.2 μM), 2 μM, 2.2 μM (0.2 μM + 2 μM), and 4 μM (2 μM + 2 μM). For Ticagrelor, the concentrations were 1 μM, 2 μM (1 μM + 1 μM), 10 μM, 11 μM (10 μM + 1 μM), and 20 μM (10 μM + 10 μM). The results showed that 4 μM Tif (Tirofiban) exhibited the strongest platelet aggregation inhibition.
