The pyrazolo[3,4-d][1,2,3]triazin-4-ones 3 and imidazo[4,5-d][1,2,3]triazin-4-ones 4 are analogs structurally related to purines that have showed a wide and significant variety of biological activity. These compounds were synthesized by one-pot diazotization of 5-amino-1H-pyrazole-4-carbonitriles 1 and 5-amino-1H-imidazole-4-carbonitriles 2, respectively.
吡唑并[3,4- d ] [1,2,3] triazin-4-ones 3和咪唑并[4,5- d ] [1,2,3] triazin-4-ones 4是与嘌呤在结构上相关的类似物表现出广泛而显着的生物活性。这些化合物分别通过一锅重氮化5-氨基-1 H-吡唑-4-腈1和5-氨基-1 H-咪唑-4-腈2合成。
Heteroarenobenzodiazepines. Part 7. Synthesis and pharmacological evaluation of a series of 4-piperazinylpyrazolo[3,4-b] and [4,3-b][1,5]benzodiazepines as potential anxiolytics

The synthesis and pharmacological evaluation of a series of pyrazolo[b][1,5]benzodiazepines are described. Some of the 4-piperazinyl-2,10-dihydropyrazolo[3,4-b][1,5]benzodiazepine derivatives demonstrated potent anxiolytic activity in the three-part operant anticonflict test in rats. Compounds 21 and 30 were more active than the clinically effective anxiolytic chlordiazepoxide in releasing conflict-suppressed
The compounds of the following formula:
1
wherein R, R

adenosine receptor antagonist activity. These compounds can be used in a pharmaceutical composition to treat disorders caused by excessive activation of the A
3
receptor, or can be used in a diagnostic application to determine the relative binding of other compounds to the A
3
receptor. The compounds can be labeled, for example with fluorescent or radiolabels, and the labels used in vivo or in vitro to determine the presence of tumor cells which possess a high concentration of adenosine A
3
receptors.
