Rivaroxaban, sold under the brand name Xarelto among others, is an anticoagulant medication (blood thinner) used to treat and prevent blood clots. [8] Specifically it is used to treat deep vein thrombosis and pulmonary emboli and prevent blood clots in atrial fibrillation and following hip or knee surgery. [ 8 ]
Modern direct Xa inhibitors are L-shaped molecules whose ends fit perfectly in the S1 and S4 pockets. The long side of the L-shape has to conform to a highly-specific tunnel within the targets active site. To accomplish that, this part of the molecules is designed to have little formal interactions with FXa in that region.
Thrombin demonstrates a high level of allosteric regulation. [2] Allosterism in thrombin is regulated by the exosites 1 and 2 and the sodium binding site. A recent patent review has shown that the general consensus among researchers is that allosteric inhibitors may provide a more regulatable anticoagulant. [3]
An anticoagulant, commonly known as a blood thinner, is a chemical substance that prevents or reduces the coagulation of blood, prolonging the clotting time. [1] Some occur naturally in blood-eating animals, such as leeches and mosquitoes, which help keep the bite area unclotted long enough for the animal to obtain blood.
The surface in the gap seems to have limiting access to molecules by steric hindrance, this binding site consists of 3 amino acids, Asp-102, His-57 and Ser-195. [9] [12] Thrombin also has two exosites (1 and 2). Thrombin is a little different from other serine proteases as exosite 1 is anion-binding and binds to fibrin and other similar ...

Once in the body, tPA has can cause the desired thrombolytic activity (see figure), or be inactivated and removed. In the bloodstream tPA has a half-life of 4 to 6 minutes. [39] tPA can be bound by a plasminogen activator inhibitor, resulting in inactivation of its activity. The protein is then removed from the bloodstream by the liver.
