Synthesis of Novel 8-alkylamino-5, 6-dihydro-4H-benzo[f] [1,2,4]triazolo [4,3-a]azepines as Anticonvulsant Agents.

A series of new 8-alkylamino-5, 6-dihydro-4H-benzo[f][1,2,4]triazolo [4,3-a]azepine derivatives were synthesized and screened for their anticonvulsant activities by the maximal electroshock (MES) test, subcutaneous pentylenetetrazol (scPTZ) test, and their neurotoxicity was evaluated by the rotarod neurotoxicity test. The results of these tests showed that 8-heptylamino-5,6- dihydro-4H-benzo[f][1,2,4] triazolo[4,3-a]azepine (7g) was the most promising compound, with median effective dose (ED50) of 19.0 mg/kg, and protective index (PI) value of 14.

Catalytic decomposition of gaseous 1,2-dichlorobenzene over CuOx/TiO₂ and CuOx/TiO₂-CNTs catalysts: Mechanism and PCDD/Fs formation.

Gaseous 1,2-dichlorobenzene (1,2-DCBz) was catalytically decomposed in a fixed-bed catalytic reactor using composite copper-based titanium oxide (CuOx/TiO2) catalysts with different copper ratios. Carbon nanotubes (CNTs) were introduced to produce novel CuOx/TiO2-CNTs catalysts by the sol-gel method. The catalytic performances of CuOx/TiO2 and CuOx/TiO2-CNTs on 1,2-DCBz oxidative destruction under different temperatures (150-350 °C) were experimentally examined and the correlation between catalyst structure and catalytic activity was characterized and the role of oxygen in catalytic reaction was discussed.
