A low-molecular-weight fluorescent probe 1 (M.W.?=?238.24) based on aurone was synthesized, and its application in fluorescent detection of Hg2+ in aqueous solution and living cells was reported. It exhibited an “on–off” fluorescent response to

A series of trifluoromethylated aurone derivatives were synthesized, and the structure of 6-hydroxy- 4-trifluoromethylated aurone was determined by single crystal X-ray analysis. Their anticancer activities against leucocythemia (HL-60) and colorectal ade

Herein we report the screening of a small library of aurones and their isosteric counterparts, azaaurones and N-acetylazaaurones, against Mycobacterium tuberculosis. Aurones were found to be inactive at 20 μm, whereas azaaurones and N-acetylazaaurones emerged as the most potent compounds, with nine derivatives displaying MIC99 values ranging from 0.4 to 2.0 μm. In addition, several N-acetylazaaurones were found to be active against multidrug-resistant (MDR) and extensively drug-resistant (XDR) clinical M. tuberculosis isolates. The antimycobacterial mechanism of action of these compounds remains to be determined; however, a preliminary mechanistic study confirmed that they do not inhibit the mycobacterial cytochrome bc1 complex. Additionally, microsomal metabolic stability and metabolite identification studies revealed that N-acetylazaaurones are deacetylated to their azaaurone counterparts. Overall, these results demonstrate that azaaurones and their N-acetyl counterparts represent a new entry in the toolbox of chemotypes capable of inhibiting M. tuberculosis growth.
