摘要:
Method for determining the biological activity of defibrotide by a) bringing into contact defibrotide, plasmin and a substrate specific for the plasmin which, by reaction with the plasmin, provides a measurable product; and b) measuring the amount of product formed at successive times, to thereby determine the biological activity of the defibrotide.
摘要:
An enzymatic method for determining the biological activity of defibrotide is described. This method, which is based on the capacity of defibrotide to potentiate the enzymatic activity of plasmin, comprises the steps of: a) bringing into contact defibrotide, plasmin and a substrate specific for the plasmin which, by reaction with the plasmin, provides a measurable product and b) measuring the amount of product formed at successive times.

Fucans with low molecular weight having anticoagulant, antithrombinic and antithrombotic activity.Fucan sulfates having molecular weight between 14000 and 29000 Dalton show a remarkable anticoagulant activity both in the global coagulation mechanism (APTT) and in the last phase of coagulation (antithrombinic activity). These compounds are useful also as antithrombotic drugs.
