  • Synthesis and Binding Activity of Some Pyrazolo[1,5-<i>c</i>]quinazolines as Tools To Verify an Optional Binding Site of a Benzodiazepine Receptor Ligand
    作者:Vittoria Colotta、Daniela Catarzi、Flavia Varano、Guido Filacchioni、Lucia Cecchi、Alessandro Galli、Chiara Costagli
    DOI:10.1021/jm9509206
    日期:1996.1.1
    The synthesis and binding activity at the benzodiazepine receptor of some 2-substituted pyrazolo[1,5-c]quinazolines are reported. The structure-activity relationships and in vitro efficacy of the title compounds, which are devoid of the proton acceptor atom at position 1, are similar to those of some previously reported tricyclic heteroaromatic compounds. This suggests that a proton acceptor at position
    报道了一些2-取代的吡唑并[1,5-c]喹唑啉在苯二氮杂receptor受体上的合成和结合活性。标题化合物在位置1上没有质子受体原子的结构活性关系和体外功效与某些先前报道的三环杂芳族化合物相似。这表明在位置1的质子受体是仅影响效力的苯并二氮杂receptor受体配体的任选结合位点。
