Toad skin secretions are a rich source of various biologically active compounds, such as alkaloids, bufadienolides, biogenic amines, or peptides. Also plants from Hyacinthaceae and Crassulaceae can be a potent source of these groups of molecules. These compounds play a crucial role in amphibians’ and plants’ physiology such as defense against predators or pathogenic microorganisms. Among them, bufadienolides are the focus of many researches in recent years. These molecules have a very interesting, steroidal chemical structure and have potent activity at the cellular level. They possess cardiotonic, antiviral, antibacterial, antitumor, anti-inflammatory, hemostatic, bacteriostatic, wound-healing, and antiparasitic properties. Although the structures of about 500 bufadienolides are known, it is strongly suggested that this group of compounds is still very poorly examined. Moreover, bufadienolides may be an excellent basis for the chemical synthesis of new drugs with selective bioactivity. The aim of this paper is to briefly overview bufadienolides as potent compounds for medicines and cosmetics.
