from the reaction of acid hydrazide 1 with alkyl or aryl isothiocyanate 2 in the presence of a KOH (10%) solution on the surface of silica gel as well as on the surface of montmorillonite K10 undermicrowaveirradiation. These triazoles have also been prepared from the reaction of 4-substituted-1-aroyl thiosemicarbazides 3a–e, with a KOH (10%) solution on the surface of silica gel undermicrowave irradiation
Discovery of Natural Sesquiterpene Lactone 1-<i>O</i>-Acetylbritannilactone Analogues Bearing Oxadiazole, Triazole, or Imidazole Scaffolds for the Development of New Fungicidal Candidates
control efficacy of compound 10 against B. cinerea was further studied using infected tomatoes (protective effect = 58.4%; therapeutic effect = 48.7%). The preliminary structure–activity relationship analysis suggested that the introduction of the 1,3,4-oxadiazolemoiety (especially the 1,3,4-oxadiazole heterocycle containing the 4-chlorophenyl, 2-furyl, or 2-pyridinyl group) on the skeleton of ABL
There is a growing need for new antibiotics and antifungal drugs to combat pathogenic bacteria and fungi. In order to develop potential antimicrobial agents, some 1,2,4-triazole-3-thiones were synthesized from the reaction of hydrazides with isothiocyanates under optimized conditions in deep eutectic solvent of potassium carbonate-glycerol (1:5 M ratio). Blocking properties of all products were assessed on a variety of Gram-positive and Gram-negative bacterial as well as fungal pathogens. Good to excellent inhibitory effects especially against fungi were observed with all synthesized compounds. 5-(4-Hydroxyphenyl)-4-(4-nitrophenyl)-2,4-dihydro-3H-1,2,4-triazole-3-thione (3b) showed significant antioxidant activity according to the results obtained from 2,2-diphenyl-1-picrylhydrazylf (DPPH) free radical scavenging experiments. The possible interaction mechanism of synthetic triazoles with 1IYL enzyme on Aspergillus fumigatus was investigated by molecular docking method. A complete agreement was found between experimental data and theoretical calculations. Hydrogen bond acceptor strength of N-1 in 1,2,4-triazole rings was the main cause of the observed differences.
