Development of a method for the sensitive and quantitative determination of hepcidin in human serum using LCMS
Hepcidin, a 25 amino acid peptide, plays an important role in iron homeostasis. As such, it has potential as an indicator of any iron-related condition, such as anemia. My research focuses on the measurement of hepcidin in biological fluids to improve our understanding of iron-related disorders. A possible result of such studies could be the development of hepcidin as a tool for diagnosis and clinical management of such disorders.Barbora Hošíková

Clinical impact of extended-spectrum beta-lactamases
The most frequent mechanism of resistance to beta-lactam antibiotics in Gram-negative bacteria is production of beta-lactamases. Those having serious clinical significance are mainly ESBL and AmpC broad-spectrum beta-lactamases and, recently, carbapenemases. For adequate antibiotic therapy of infections caused by producers of these enzymes, it is necessary to not only rapidly and correctly identify the etiological agents and their susceptibility to antibiotics but also detect the presence of these dangerous phenotypes of resistance. One of the objectives of this dissertation was to determine the sensitivity of phenotypic methods for detecting broad-spectrum beta-lactamases and carbapenemases and to select the most suitable ones for routine microbiology practice.Katarína Chromá

Using novel anti-cancer agents in elucidation of DNA damage response (DDR) mechanisms and their role in onset of cancer
The thesis is centered on cellular responses, termed DNA damage response (DDR) to DNA double-strand breaks, presumably the most deleterious lesions affecting DNA. The aim of the thesis is to shed more light on certain mechanistic aspects of the DDR. To this end, several chemical inhibitors interfering with different key steps of the DDR are utilized. Apart from deciphering the underlying mechanisms, this approach might lead to new diagnostic and therapeutic approaches.Sylwia Jančík

Diversity-Oriented Synthesis Using Immobilized 2/4-Nitrobenzensulfonamides As The Key Intermediates
The Ph.D. thesis is focused on the diversity-oriented synthesis using immobilized 2/4-nitrobenzensulfonamides as the key intermediates to prepare single and fused nitrogenous heterocycles. The preparation of these derivatives was performed using solid-phase synthesis (SPS) that yielded the common intermediate, i.e. α-amino ketone which was further modified to final products. The general concept of SPS and its (dis)advantages are briefly discussed in Introduction of this thesis. The following subchapter introduces the previous research in the field of N-sulfonyl and N-acyl morpholine-3-carboxylic acid derivatives which has become a major inspiration for all of our projects described in this thesis. The following chapter Aims of the work provides the specific goals in more details. After that, the thesis continues as the State of the art to display shortly the general application of immobilized 2/4-nitrobenzensulfonamides and α-amino ketones to prepare diverse heterocycles. This subchapter is supplemented by our review article summarizing the polymer-supported syntheses of heterocycles bearing oxazine and thiazine scaffolds which is attached in Appendix B at the end of this thesis. Then the part of Results and discussion follows which is divided into eight subchapters according to the individual synthetic projects. In Conclusion part, all results are briefly summarized.Jakub Malohlava

Development of Strategies for Solid-Phase Synthesis of Nitrogenous Heterocyclic Compounds Based on the 2- and 4-Nitrobenzenesulfonamide Chemistry
The submitted doctoral thesis deals with the development of simple procedures applicable for the preparation of libraries of selected heterocyclic compounds. In all of the introduced procedures, the immobilized 2- or 4-nitrobenzenesulfonamides were used as the key intermediates. Different scenarios have been used in which the nitrobenzenesulfonyl (Nos) group was applied (1) only as a protective/activating group for Fukuyama selective monoalkylation followed by the cleavage of the sulfonamide scaffold, (2) as a building block after previous Fukuyma alkylation, or (3) as a building block without application of Fukuyama alkylation. The key intermediates were further modified and converted to the target products under different cyclization conditions. During our long-term research we have developed high-throughput solid-phase syntheses of various heterocyclic compounds involving six types of different scaffolds.Gabriela Rylová

The role of the ubiquitin-proteasome system in tumorigenesis and cancer treatment
Regulated protein degradation is mediated by ubiquitin-proteasome system. Inhibition of proteasome proteolytic activity is a promising approach in cancer therapy with first-in-class drug bortezomib approved for the treatment of patients with multiple myeloma. Since ubiquitination regulates not only protein degradation but also wide variety of cellular signaling pathways, this new approach might bring new drugs with better efficacy and safety profiles.Michaela Šváchová
