3. 6 - Disubstituted [1, 2, 4] triazolo [3, 4 - b] [1, 3, 4] thiadiazole compound and use thereof

The invention discloses 3,6-disubstituted[1,2,4]triazolyl[3,4-b][1,3,4]thiadiazole compounds represented by general formula (I), and pharmaceutically acceptable salts or pharmaceutically acceptable solvates thereof. The compounds can be used as a transpeptidase SrtA inhibitor of Staphylococcus aureus, Bacillus pyogenes, Bacillus anthracis, Streptococcus pneumoniae and other Gram-positive bacteria, and can be used to prepare drugs for treating pathogen infection diseases with the transpeptidase SrtA of the Gram-positive bacteria, such as Staphylococcus aureus, Bacillus pyogenes, Bacillus anthracis and Streptococcus pneumoniae as target. The compounds avoid selection pressure induced drug resistance of pathogens to a certain degree, and mitigate threat of continuous drug-resistant pathogens to the health of human.

Synthesis and biological activity of 3-(2-furanyl)-6-aryl-1,2,4-triazolo[3, 4-b]-1,3,4-thiadiazoles

3-(2-Furanyl)-4-amino-5-mercapto-1,2,4-triazole (1) was prepared from 2-furoic acid through a multi-step reaction sequence. Compound 1 reacted with aromatic acids in the presence of phosphorus oxychloride to give 3-(2-furanyl)-6-aryl-1,2,4-triazolo[3,4-b]-1,3,4-thiadiazoles (2). The structures of all the newly synthesized compounds have been confirmed by elemental analysis, IR, 1H-NMR, 13C-NMR and mass spectra. The bioassay indicated most of the title compounds possess significant growth promoting effects on mung bean radicles.
