Novel 1, 2, 4-Triazoles as Antifungal Agents. [PDF]

open access: yesBiomed Res Int, 2022
The development of innovative antifungal agents is essential. Some fungicidal agents are no longer effective due to resistance development, various side effects, and high toxicity. Therefore, the synthesis and development of some new antifungal agents are necessary. 1,2,4‐Triazole is one of the most essential pharmacophore systems between five‐membered

Regioselectivity in the Thermal Rearrangement of Unsymmetrical 4-Methyl-4H-1,2,4-triazoles to 1-Methyl-1H-1,2,4-triazoles [PDF]

open access: goldMolecules, 2001
The rearrangement of 4-methyl-3,5-diaryl-4H-1,2,4-triazoles to the corresponding 1-methyl-3,5-diaryl-1H-1,2,4-triazoles showed regioselectivity comparable to that observed for the alkylation of 3,5-diaryl-1H-1,2,4-triazoles.

Comparative Study of Goitrogenic Actions of 3-Substituted 1, 2, 4-Triazoles in Rats.

open access: bronzeJournal of Veterinary Medical Science, 1994
Antithyroid actions of 3-amino-1, 2, 4-triazole (ATZ), 3-mercapto-1, 2, 4-triazole (MTZ) and 3-nitro-1, 2, 4-triazole (NTZ), which are substituents on the 3-position of 1, 2, 4-triazole (TZ), and those of the parental compound, were compared in rats. After administration of either ATZ, MTZ, or NTZ, the thyroids of rats were enlarged with decreasing of ...
