制备新的三环杂环并评估其对中央苯并二氮杂receptor受体的亲和力。IC 50在纳摩尔范围内的最有效化合物为:在噻吩并喹啉和苯并[ a ]喹啉中发现(参见表2-5)。三环系统的中心环可以是部分不饱和的(参见表2和4)或完全不饱和的(参见表3和5),而不会丧失对受体的高亲和力。吡啶酮环中酯基的位置对于良好结合至关重要(参见表1和2)。)。它可以被各种官能团取代,例如酰胺,氨基甲酸烷基酯,烷基和羟烷基(参见表2-5)。在苯并[ a ]喹啉衍生物中,将卤素原子从C(10)移至C(9)会导致与苯并二氮杂receptor受体的亲和力完全丧失(请参阅表4)。
In order to investigate the origin of the loop-type diureticactivity of M17055 (1), several variants (3-9) were designed and synthesized by modifying the quinolinone skeleton, and their diureticactivities were compared with the lead 1 and furosemide in dogs. It was found that the negative charge distribution pattern afforded by the dispositional arrangement of the 4-oxime-O-sulfonic acid and 1-N-acyl
Novel tricyclic heterocycles were prepared and evaluated for their affinity to the centralbenzodiazepinereceptor. The most potent compounds with IC50's in the nanomolar range were; found among thienoquinolizines and benzo[a]quinolizines (cf. Tables 2–5). The central ring of the tricyclic ring system may be partially unsaturated (cf. Tables 2 and 4) or fully unsaturated (cf. Tables 3 and 5) without
