Oxazepam (4a) has been used as overall starting material in the synthesis of novel 2-substituted 1,4-benzodiazepines. By reacting Oxazepam 4a with commercially available hydrazines, hydrazides, semicarbazide, aminoguanidine and N,N-dimethylamino aniline in ethanol under acetic conditions, a series of diazenyl-1,4-benzodiazepines 5a-5i and 2-amino- 1,4-benzodiazepine 5k were obtained in good yields. These novel compounds served as new chemical entities (NCE) for testing in mice. The diazo-benzodiazepine 5d has shown a promising antidepressant effect in initial experiments in vivo at a dose of 5 mg/kg. The highly coloured 2-aminobenzodiazepine derivative 5k showed over a dose range from 5-50 mg/kg an analgesic effect in mice. © Singh et al.
