Synthesis and antimicrobial evaluation of new 2-substituted 5,7-di-tert-butylbenzoxazoles

Various synthetic pathways of the 30 novel 2-substituted 5,7-di-tert-butylbenzoxazoles as new potential antimicrobial drugs are discussed. The 28 intermediates are described as well. The compounds were characterized by 1H and 13C NMR spectra, MS spectra, IR/UV spectra and by means of CHN analysis. The purity of the final compounds was checked by HPLC and their lipophilicity (log K) was also determined by means of RP-HPLC. In the present study, the correlation between RP-HPLC retention parameter log K (the logarithm of capacity factor K) and various calculated log P data is shown. The target compounds were tested for their in vitro antimycobacterial activity. Several compounds showed antituberculotic activity comparable with or higher than the standard isoniazide. In vitro cytotoxicity testing of the most active benzoxazoles and isoniazide as a reference drug was performed using MTT assay and compared with isoniazide as a reference drug. Structure-activity relationships among the chemical structures, the physical properties and the biological activities of the evaluated compounds are discussed in the article.

Oxidative Cyclization of Sterically Shielded o-Hydroxy Azomethines

Efficient methods have been developed for preparation of sterically shielded benzoxazoles from 2-amino-4,6-di-tert-butylphenol.The mechanism of one-electron oxidation of the azomethines to 2-aryl-substituted benzoxazoles has been studied by ESR spectroscopy.The UV spectra and luminescent properties of these heterocycles have been examined. changes in absorption and luminescence spectra of the heterocycles on passing from the neutral form to the anion and then to the radical have been analyzed with 2-(3,4-di-tert-butyl-4-hydroxyphenyl)-5,7-di-tert-butylbenzoxazole as an example.The experimental results suggest the possibility of using these compounds as efficient antioxidants in photo- and thermooxidative processes.
