BODIPY Fluorophores for Evaluating Coagulation Hemostasis Kinetics in Physiological and Pathological States

Molecular sensors are a new and rapidly developing tool in biochemical research. They enable the exploration of biochemical reaction mechanisms and the prompt diagnosis of pathological conditions. Fluorescent dyes based on boron dipyrromethene (BODIPY) complexes are widely used as molecular sensors. This study demonstrates the potential for characterizing processes occurring in the blood plasma coagulation system across different age groups, including patients with acute myocardial infarction. In elderly individuals, compared to younger people, the blood clotting process begins earlier, the formation of fibrin slows down, and thrombin activity decreases. This technique can detect an increase in thrombin activity accompanied by a higher concentration of fibrinogen in patients with heart pathology. In such cases, blood clotting starts later and lasts longer. These changes in indicators can be attributed to the emergency administration of heparin. On the one hand, heparin prevents the enlargement of a blood clot; on the other, it reduces the activity of the prothrombinase complex, which is beneficial for patients with myocardial infarction. Further observation of blood clotting reveals alterations in fibrin structure, leading to a lengthened stabilization time. Thus, the results obtained in this study are consistent with the literature. The presented method is applicable both for physiological studies of the coagulation process and in clinical practice. Additionally, this method can be used for the kinetic evaluation of anticoagulants’ effects on hemostasis factor activity.
