(11) ų, Z = 2. In addition, DIZ and MIC assays were used to examine the in vitro antifungal activity of the title conjugates 5a⁻o against four fungal strains. Compound 5e, bearing a 4-ethoxyphenyl fragment, showed the best MIC value (0.304 µmol/mL) against both C. tropicalis and C. parapsilosis species, while compounds 5c (MIC = 0.311 µmol/mL), 5k, and 5l (MIC = 0.287 µmol/mL) exhibited the best anti-C
Synthesis of 3-(tri/difluoromethyl)-1<i>H</i>-1,2,4-triazol-5(4<i>H</i>)-ones <i>via</i> the cyclization of hydrazinecarboxamides with tri/difluoroacetic anhydride
An efficient method for the synthesis of structurally diverse 4-aryl-3-(tri/difluoromethyl)-1H-1,2,4-triazol-5(4H)-ones through the cyclization of hydrazinecarboxamides with tri/difluoroacetic anhydride is presented. The method is simple and environmentally benign, providing tri/difluoromethylated 1,2,4-triazol-5(4H)-ones in moderate-to-good yields. A mechanism is proposed to proceed via a tandem reaction
Compounds of Formula I and pharmaceutically acceptable salts thereof, are capable of blockading voltage-dependent sodium channels and are useful in particular, in treating glaucoma and multiple sclerosis.
