Реферат: New usnic acid (UA) derivatives were investigated in vitro to elucidate their potential inhibitory activities on the growth of Mycobacterium smegmatis and Mycobacterium tuberculosis. Seven pairs of enantiomers of thiazole UA derivatives were tested using the M. smegmatis strain mc(2) 155 test system, and the "structure-activity" relationship was established. The most active compounds were (+)-3 and (-)-3, and their kinase inhibitory activities were investigated. The results obtained using the Streptomyces lividans APHVIII+ and M. smegmatis APHVIII+ test systems indicated the significant protein kinase activity of these compounds and revealed the species specificity of the actions of the dextro- and levorotatory isomers. Both isomers, (+)-3 and (-)-3, possess similar inhibitory activity against M. tuberculosis H37Rv. The action of the isomers on eukaryotic cells was also investigated, and the results demonstrate that the dextrorotatory isomer (+)-3 leads to the lysis of intact macrophages to a degree higher than that obtained spontaneously and significantly higher than that obtained with the levorotatory isomer.
