Enzyme kinetic evaluation of several potential inhibitors of certain human cysteine and serine proteases

IN ENGLISH Charles University Faculty of Pharmacy in Hradec Králové Department of Biological and Medical Sciences Supervisors: prof. Dr. Michael Gütschow RNDr. Klára Konečná, Ph.D. Candidate: Michaela Hympánová Title of the diploma thesis: Enzyme kinetic evaluation of several potential inhibitors of certain human cysteine and serine proteases Background Cysteine and serine proteases are enzymes involved in many physiological processes. The imbalance between them and their endogenous inhibitors is associated with various diseases such as cancer and osteoporosis. Synthetic inactivators could be useful in the treatment of these enzyme-mediated pathological conditions. Therefore, there are ongoing attempts to develop low-molecular weight inactivators for therapeutically relevant cysteine and serine proteases. In the course of this thesis, compounds synthesized in prof. Gütschow's group were investigated as potential inhibitors of selected human proteases. They belong to imidazole compounds derived from N-protected cyclohexylalanine, 2-phenyl-7,8-dihydroimidazo[1,2- a]pyrazin-6(5H)-one derivatives, ,-unsaturated peptidomimetic compounds, carbamates, an N,N-dibenzylcrotonamide derivatives and peptoides. Aims This diploma thesis has been focused on the evaluation of new potential inhibitors against..
