In vitro screening of potential antimycobacterial compounds against fast growing strains of Mycobacterium genus II

Charles University Faculty of Pharmacy in Hradec Kralove Department of Biological and Medical Sciences Study program: Specialist on Laboratory Methods Author: Bc. Tereza Pchálková Supervisor: PharmDr. Ondřej Janďourek, Ph.D. Title of diploma thesis: In vitro screening of potential antimycobacterial compounds active against fast growing strains of Mycobacterium genus II Key words: Mycobacteria, Tuberculosis, Antituberculotics, Microdilution broth method, Minimum inhibition concentration Background: The aim of this diploma thesis has been screening of in vitro antimycobacterial activity of novel compounds against fast growing strains of the genus Mycobacterium (Mycobacterium smegmatis and Mycobacterium aurum). Another aim has been predicting the structure-activity relationships for tested compounds. Methods: The technique used for activity determination was microdilution broth method. The value of minimum inhibition concentration for each compound was determined. The evaluation was performed visually and spectrophotometrically using the Alamar blue indicator. Results: A total of 79 compounds were tested. 22 tested compounds showed significant activity against mycobacteria. The substances were sorted according to the similarity in chemical structure into 10 groups. From a chemical point of view, these..
