UsesAprotinin is largely used as an inhibitor of trypsin.
UsesProteolytic inhibitor in radioimmunoassays of polypeptide hormones.
Manufacturing Process1 kg of parotid of cattle, which were freed of fat and flesh are comminuted in a meat chopper and twice extracted with 5 L of acetone. The acetone was removed as far as possible by sucking off and the moist material is digested for 2.5 hours in 1.2 L of 1 N acetic acid and 2.8 L of 96% ethanol at 50°C. The filtrate containts about 230.000 inactivator units.
The alcoholic solution is concentrated to 1.2 L by evaporating in vacuo and shaken with an equal amount of ether. Dark coloring matters and residues of fat are thus dissolved. The aqueous phase is now mixed with acetone until a precipitate occurs and the dissolved in dilute acetic acid. The solution is brought to a weakly alkaline pH by addition of ammonia. It is then centrifuged and the inactivator is precipitated with five times the amount of ethanol. The yield amounts to about 180.000 kallikrein inactivator units in 0.4-0.5 g of substance.
Brand nameTrasylol (Bayer).
Therapeutic FunctionProteinase inhibitor
Safety ProfileExperimental reproductive effects. When heated to decomposition it emits toxic fumes of NOx and SOx.
