Cetraxate (INN) is an oral gastrointestinal medication which has a cytoprotective effect.[1][2]Template:Unreliable medical source

Synthesis

Cetraxate is a prodrug of tranexamic acid. The latter is a hemostatic agent because it inhibits the activation of plasminogen to plasmin. The result is to prevent excess loss of blood in gastrointestinal ulcers. The synthesis begins with the esterification of 3-(p-hydroxyphenyl)propionic acid (2) by trans-4-cyanocyclohexanecarbonyl chloride (1). The product (3) is reduced to cetraxate (4) by catalytic hydrogenation with hydrogen and Raney nickel.[3][4]
