Figure 3. Anticoagulant activity of exactin.

Figure 3

(A) Effect of exactin (1 μM to 300 μM) on the coagulation of human plasma: prothrombin time (■), Stypven time (♦), APTT (●) and thrombin time (▲). (B) Identification of specific site of action of exactin. Effect of exactin on reconstituted ETC (■), intrinsic tenase complex (●), prothrombinase complex (▼) and thrombin (▲). (C) Mechanism of inhibition of the extrinsic tenase complex. The effect of exactin on the sequential removal of each component of the ETC: removal of TF [FVIIa/FX/phospholipids (●)] and phospholipids [FVIIa/sTF/FX (▲)] compared to full complex [FVIIa/TF/FX/phospholipids (■)]. For comparison, dose-response curve of the effect of exactin on ETC is shown in dotted line. (D) Effect of exactin on hydrolysis of small peptides. The effect of exactin on amidolytic activity of FVIIa (●), FVIIa/sTF (■), and FVIIa/phospholipids (▲). Each data point represents the average ± SD of three independent experiments.
