  描述：

  N-丙炔基邻苯二甲酸胺 、 5-(2-fluorophenyl)-7-iodo<1,2,4>triazolo<4,3-a>quinazoline 在 copper(l) iodide 、 palladium diacetate 、 三乙胺 、 三苯基膦 作用下， 以 N,N-二甲基甲酰胺 为溶剂， 反应 72.0h， 以54%的产率得到2-{3-[5-(2-Fluoro-phenyl)-1-methyl-5a,9a-dihydro-[1,2,4]triazolo[4,3-a]quinazolin-7-yl]-prop-2-ynyl}-isoindole-1,3-dione

  Triazolobenzo- and triazolothienodiazepines as potent antagonists of platelet activating factor

  摘要：

  A series of [1,2,4]triazolo[4,3-alpha][1,4]benzodiazepines bearing an ethynyl functionality at the 8-position and the isosteric thieno[3,2-f][1,2,4]triazolo[4,3-alpha][1,4]diazepines were prepared and evaluated as antagonists of platelet activating factor. The effects of substitution were explored in in vitro and in vivo test systems designed to measured PAF-antagonistic activity. Results are discussed and compared with previously published data. Many of the compounds had activity superior to WEB 2086, compound 1. In general, the thieno analogues exhibited better oral activity than the corresponding benzodiazepines. The duration of activity upon oral administration was modulated by the substitution on the acetylenic side chain. Compounds 71 and 81 were selected for further pharmacological evaluation as a result of their good oral potency and exceptionally long duration of action.
