Synthesis of 5-benzyl-4-aryl-octahydro-1H-benzo[b][1,5]diazepin-2-ones as potent antidepressant and antimicrobial agents
摘要:
The present study describes the chemical synthesis and pharmacological evaluation of a new series of 11 compounds of aryloctahydrobenzo[b][1,5]-diazepin-2-one in the forced-swimming test in mice. Three compounds (3e, 3f and 3h) exhibited impressive antidepressant activity, measured in terms of percentage decrease in immobility duration. The potent compounds did not show any neurotoxicity in the rotarod test, and the preliminary results are promising enough to warrant further studies around this scaffold. All the compounds were also screened for antimicrobial activity against P. aeruginosa, E. coli, S. Aureus and B. subtilis strains. Some of the compounds possessed marked antimicrobial activities comparable to that of reference drug, Ciprofloxacin.
We report here a simple entry into N-substituted decahydroisoxazoloquinoline system with substituents at position 3 and 4 from the readily available substrates for the first time. The synthesized iso-xazoloquinolines were evaluated against six bacterial and four fungal strains. The results suggest that the decahydroisoxazolo[4,3-c]quinoline scaffold has the potential to be developed into therapeutically useful antimicrobial agents. (C) 2011 Elsevier Masson SAS.
