Since nowadays the chemical synthesis of new bioactive compounds is a complicated and expensive procedure, alongside with the increased price for drugs based on synthetic biologically active compounds, scientists lay emphasize on natural sources as a promising raw material for various biologically active substances. Amphibian skin glands secretions are a powerful source of potential pharmacological agents. Currently their antimicrobial, antiviral, cardiotonic and antidiabetic activities have been studied in detail, although almost nothing is known about the effects of the tailless amphibians' skin secretions on the functioning of the hemostasis system. The aim of this study was to analyze the potential effects of the components of skin glands secretions of a representative of Ukrainian batrakhofauna – the Common spadefoot toad (Pelobates fuscus) on some parameters of hemostasis system. In the result of chromatographic separation of general skin secretions, 4 protein fractions were obtained, containing a variety of proteins with molecular masses ranging from 17 to 150 kDa. The components of fraction 1 activated prothrombin and factor X in plasma. Several components of fraction 4 had proteolytic activity and substrate specificity for collagen. The components of fractions 1 and 2 prolonged plasma coagulation time in the APTT. Thus, it was proved the presence of biologically active compounds in the P. fuscus skin secretions, that indicates the prospects for further research to identify the individual components responsible for the manifestation of the shown effects in order to provide clues in understanding the structural and functional characteristics and mechanism of action. Moreover, advances in this area will further increase the use of amphibian skin secretions as a raw material for the development of new original pharmaceutical agents and/or biotechnological products
