Charles University Faculty of Pharmacy in Hradec Králové Department of Pharmacology & Toxicology Student: Martina Sýkorová Supervisor: RNDr. Jakub Hofman, Ph.D. Title of diploma thesis: Study on impact of selected tyrosine kinase inhibitors on multidrug resistance mediated by ABC drug efflux transporters Tyrosine kinases are an important class of enzymes controlling cell proliferation, carcinogenesis, apoptosis and cell differentiation. Deregulation of these enzymes can transform normal cell into a cancerous one. Blocking their function by tyrosine kinase inhibitors (TKi) is considered a promising treatment for various types of cancer. ATP-binding cassette (ABC) transporters form a family of transmembrane proteins that can transport a wide variety of substrates across biological membranes via ATP-dependent drug efflux pumps. They modulate drug pharmacokinetics, but on the other hand, lead to therapy failure due to overexpression in cancer cells. In our previous study, we evaluated inhibition properties of two selected TKi (alectinib, brivanib) in MDCKII cell lines (parent one and those transduced with human ABCB1, ABCC1 and ABCG2). Alectinib significantly inhibited ABCB1, ABCG2 but not ABCC1 transporter. Brivanib showed triple inhibition of all studied transporters. In the present work, we...
