A series of 1,2,4‐triazole‐3‐thionederivatives (6a–6t) were synthesized and evaluated against influenza viruses (H1N1) neuraminidase (NA) in vitro. Eighteen compounds exhibited inhibitory potency with IC50 values ranging from 14.68 ± 0.49 to 39.85 ± 4.23 μg/mL. Among them, compounds 6e and 6h showed significant inhibitory activity with IC50 values of 14.97 ± 0.70 and 14.68 ± 0.49 μg/mL, respectively
The synthesis of a series of 21 novel 3‐alkyl/aryl‐7/9‐methyl‐10,10a‐dihydroindeno[1,2‐e][1,2,4]triazolo[3,4‐b][1,3,4]thiadiazines (4) has been achieved by the cyclocondensation between 4/6‐methyl‐2‐tosyloxy‐1‐indanones (2) and 3‐alkyl/aryl‐4‐amino‐5‐mercapto‐1,2,4‐s‐triazoles (3). 4/6‐Methyl‐2‐tosyloxy‐1‐indanones (2) were readily accessible through hypervalent iodine oxidation of 4/6‐methyl‐1‐indanones

Two series of compounds namely, dihydroindeno and indeno [1,2-e] [1,2,4]triazolo [3,4-b] [1,3,4]thiadizines (9a–l & 11a-l) were synthesized by cyclocondensation between α-bromoindanones (7a–b) or/and α,α-dibromoindanones (8a–b) and various 3-alkyl/aryl-4-amino-5-mercapto-1,2,4-s-triazoles (3a–f) in methanol with an aim to explore their effect on in vitro growth of microorganism causing microbial infection

Regardless of the conditions, the condensation of 4-amino-2,4-dihydro-3H-1,2,4-triazole-3-thiones with aromaticaldehydes afforded the corresponding hydrazones as the only product. Both initial amines and resulting hydrazones exist as the thione rather than thiol tautomer. In no case bicyclic 5,6-dihydro[1,2,4]triazolo[3,4-b][1,3,4]thiadiazoles that are isomeric to the hydrazones were detected. DFT
无论条件如何,4-氨基-2,4-二氢-3 H -1,2,4-三唑-3-硫酮与芳族醛的缩合得到相应的为唯一产物。初始胺和生成的均以硫酮而不是硫醇互变异构体的形式存在。在任何情况下均未检测到与酮异构体的双环5,6-二氢[1,2,4]三唑并[3,4- b ] [1,3,4]噻二唑。B3LYP / 6-31 + g(d,p的DFT量子化学计算))具有完整几何优化的理论水平表明,甲醇和DMF中的structure结构比双环异构体稳定19-23 kcal / mol,这完全排除了这种环化的可能性。的硫酮互变异构体比硫醇结构稳定11-13 kcal / mol。
