  摘要：

  A new series of 3-, 7- and 8-substituted pyrazolo[5,1-c][1,2,4]benzotriazine 5-oxides and a series of pyrazolo[5,1-c][1,2,4]benzotriazines were synthesized and their benzodiazepine receptor affinities were evaluated in vitro. A study of structure-affinity relationships within the series is briefly discussed, considering the role of various substituents at the 3-, 7- and 8-positions and the role of N-5-oxide. Compounds 1b, 1c, 1cR, 4c, 4cR, 9d, 12d and 12dR were evaluated in vivo for their anticonvulsant effects.

  1-(2-nitrophenyl)-5-aminopyrazoles under basic conditions has been reinvestigated and the structures of the obtained pyrazolo[5,1-c][1,2,4]benzotriazine 5-oxides confirmed by spectroscopic means. In particular the different aromatic nucleophilic attack on 8-chloro derivatives 4a and 6a and 7-nitro derivatives 11a and 12a was determined. From these latter compounds unexpected (phenyl-ONN-azoxy)pyrazoles were isolated
