  Benzodiazepine receptor ligands. Synthesis and pharmacological evaluation of 3-, 7- and 8-substituted [5,1-c][1,2,4]benzotriazines and 5-oxide derivatives. Part I

  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.

  A new series of pyrazolo[5,1-c-][1,2,4]benzotriazine 5-oxide 8-alkyloxy-/aryloxy-/arylalkyloxy and 8-aryl-/arylalkylderivatives variously substituted at the 3-position were synthesized and binding studies at the benzodiazepine site on GABA(A) receptor were carried out. The pharmacological profile was identified for compounds 10, 11, 16(+), 16(-), and 17 by considering six potential benzodiazepine actions: motor coordination, anticonvulsant action, spontaneous motility and explorative activity, potential anxiolytic-like effects, mouse learning and memory modulation., and finally, ethanol-potentiating action. Compound 17 stands out as the compound that improves mouse memory processes selectively, safely, and in a statistically significant manner. From a ligand-based pharmacophoric model, we identified a hydrogen bond interaction area HBp-3 near the lipophilic area. This new pharmacophoric model allowed us to identify four structural compound typologics and thus to rationalize the affinity data of all compounds.

  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
