Charles University, Faculty of Pharmacy in Hradec Králové Department of Pharmaceutical Chemistry and Pharmaceutical Analysis Title of the thesis: Design, synthesis and evaluation of heterocyclic compounds with potential antimicrobial activity I Author: Michal Brányik Supervisor: doc. PharmDr. Jan Zitko, Ph.D. Consultant: PharmDr. Martin Juhás, Ph.D. Antimicrobial resistance is an ever-growing problem that occurs worldwide. Many bacterial strains develop the ability to resist the otherwise efficient substances, thus posing a serious threat for the future. Mycobacterium tuberculosis (Mtb), the source of tuberculosis, is no exception. Given that it is the leading cause of death due to a single pathogen, many efforts have been put into finding new active compounds. The substances synthesized as a part of this thesis are based on previously prepared substances with potential antimicrobial activity. The basic structure consists of 2-aminooxazole or 2-aminothiazole and substituted pyridine or pyrazine carboxamides. The structures were confirmed by the 1 H and 13 C NMR spectra, IR spectra and mass spectrometry. All the substances were tested for in vitro activity against eight bacterial strains (four gram-positive and four gram-negative) as well as eight fungal strains (four yeast and four fungi). We also...
