    Our research is mainly focusing on the modification of selected groups of alkaloids and study their structure–activity relationships.

    Alkaloids are an important class of naturally occurring organic compounds. Many of them have been widely used as a pharmaceutical lead scaffold for constructing various biologically active compounds. As part of our research, several new indole, purine, and pyridine derivatives were obtained. These include, among others, sulfur and selenium nicotine derivatives, aminocaffeine derivatives and gramine-uracil conjugates. Moreover, as we have show in our previous study, one of the gramine derivatives obtained by us turned out to be highly selective for liver cancer cells (HepG2), making it a very promising antiproliferative agent treatment of liver cancer.

    Antioxidant compounds play an important role as a health protecting factor by reducing the risk of chronic diseases induced by ROS, including cancer and heart disease. Therefore, the caffeine and gramine molecules remain in the focus of our interest for further modification in the hope of increasing their antioxidant and cytoprotective properties. The antioxidant and cytoprotective properties of the new derivatives are analyzed using standard chemical tests and an in vitro cell system using human erythrocytes as model cells in the study of the biological activity of the compounds. Research on human erythrocytes is conducted in cooperation with the Faculty of Biology of the Adam Mickiewicz University.
