Cardiovascular diseases are the leading cause of death in the world and are caused by clots in the circulatory system. Thrombolytic drugs activate plasminogen toward plasmin that degrades fibrin networks, a component that stabilizes clots. These drugs can also activate circulating plasminogen, producing plasmin, which can degrade other proteins, causing bleeding. For this reason, there is interest in the search for drugs that directly degrade fibrin. FhT enzymes and their recombinant form (rFhT) degrade fibrin in vitro. In this thesis, conditions were established to induce tail thrombosis with kappa-carrageenan and this model was used to evaluate the thrombolytic activity of FhT and rFhT. The conditions to induce thrombosis such as acclimatization of the mice for 3 weeks at 24 °C, dissolution of k-carrageenan at 85 °C and administration of the k-carrageenan solution at 50 °C at a dose of 20 mg/ kg resulted in a tail thrombosis percentage of 90 ± 4 %. Mice induced to thrombosis with k-carrageenan 20 mg/kg and treated with 20 mg/kg rFhT had a significantly lower percentage of tail thrombosis (58.2 ± 13.1 %) compared to mice induced to thrombosis and treated with saline solution (92.8 ± 11.2 %). No significant differences were found in the percentage of thrombosis in the mice induced to thrombosis and treated with FhT 20 mg/kg compared to mice induced to thrombosis and treated with saline solution.
