Usage

Uses

Used in Pharmaceutical Industry:
Vorapaxar is used as an antiplatelet agent for the prevention of thrombotic events in patients with a history of myocardial infarction, peripheral arterial disease, or those undergoing coronary artery bypass grafting. It works by inhibiting the PAR-1 receptor, which reduces platelet aggregation and the risk of blood clot formation.
Additionally, Vorapaxar may be used in research settings to study the role of the PAR-1 receptor in platelet function and the development of new therapeutic agents targeting this receptor.

Preparation method of vorapaxar intermediate

The invention belongs to the field of organic synthesis and drug synthesis, and relates to a preparation method of a vorapaxar intermediate. The preparation method comprises following steps: racemic (E)-3-(5-amino cyclohexyl-1-ene-yl) acrylic acid or an ester compound of (E)-3-(5-amino cyclohexyl-1-ene-yl) acrylic acid is reacted with D-malic acid so as to obtain optically pure (R, E)-3-(5-amino cyclohexyl-1-ene-yl) acrylic acid or a D-malate of the ester compound of (E)-3-(5-amino cyclohexyl-1-ene-yl) acrylic acid via resolution, and the obtained product is converted into (R,E)-3-(5-((ethoxycarbonyl)amino) cyclohexyl-1-ene-1-yl) acrylic acid; and at last the intermediate is converted into a subsequent intermediate of vorapaxar. Compared with the prior art, the preparation method possessesfollowing advantages: the yield is increased obviously, the raw materials are easily available; the production cost is low; the preparation method is simple; operation is convenient; the reaction reagents are friendly to the environment; the preparation method is better than the prior art, and is especially suitable for industrialized production.
