Charles University Faculty of Pharmacy in Hradec Králové Department of Biochemical Sciences Candidate: Alžbeta Tomanová Supervisor: RNDr. Eva Novotná, Ph.D. Title of diploma thesis: Effect of selected tyrosine kinase inhibitors on the activity of human carbonyl reducing enzymes Key words: tyrosin kinases, screening, carbonyl, daunorubicin, inhibition Tyrosine kinases are a subclass of protein kinases, catalysing the transfer of ATP phosphate residue to a protein, thereby playing an important role in cellular signaling. Abnormal tyrosine kinase activity is present in various malignancies. In certain cases, inhibition of their function can prevent tumor cell proliferation and eventually induce apoptosis. At the same time, some tyrosine kinase inhibitors have demonstrated the ability to inhibit efflux transporters, which are often involved in the development of resistance to anticancer treatment. In this diploma thesis, the inhibitory effect of imatinib, nilotinib, dasatinib and acalabrutinib (tyrosine kinase inhibitors) has been studied on carbonyl reducing enzymes, whose overexpression by tumor cells may lead to resistance to chemotherapy. In particular, in the case of anthracyclines, the reduction of carbonyl group on C-13 results in not only lower cytotoxic activity, but also increased...
