制备并评估了一系列苯并[h] [1,6]萘啶和氮杂[3,2-c]喹啉衍生物,以确定对5-HT(4)受体具有高亲和力以及与其他化合物相比具有高选择性的必要要求受体。通过用各种N-烷基-4-哌啶基甲醇酯取代苯并萘啶和氮杂喹啉的氯原子来合成化合物。他们在与[(3)H] GR 113808作为5-HT(4)受体放射性配体的结合测定中进行了评估。亲和力值(K(i)或抑制百分比)一方面取决于芳环上的取代基,另一方面取决于侧哌啶链上的取代基。氯原子的活性显着下降,而N-丙基或N-丁基使化合物具有纳摩尔亲和力(1
Heating of hexahydro-5H-pyrrolo[2,1-c][1,4]benzodiazepine-2,5,11-trione in boiling phosphoryl chloride led to a rearranged product like 3,5-dichlorobenzo[h][1,6]naphthyridine. This structure was established from X-ray diffraction analysis.

Rearrangement of pyrrolo[2,1-c][1,4]benzodiazepines into cyclopenta[b][1,4]benzodiazepines under microwave or conventional heating conditions
Microwave or conventional heating of 2-hydroxy or 2-oxo-pyrrolo[2,1-c][1,4]benzodiazepinediones in boiling phosphoryl chloride led to cyclopenta[b][1,4]benzodiazepines. (C) 1997 Published by Elsevier Science Ltd.
New Benzo[<i>h</i>][1,6]naphthyridine and Azepino[3,2-<i>c</i>]quinoline Derivatives as Selective Antagonists of 5-HT<sub>4</sub> Receptors: Binding Profile and Pharmacological Characterization
A series of benzo[h][1,6]naphthyridine and azepino[3,2-c]quinolinederivatives were prepared and evaluated to determine the necessary requirements for high affinity on the 5-HT(4) receptors and high selectivity versus other receptors. The compounds were synthesized by substituting the chlorine atom of benzonaphthyridines and azepinoquinolines with various N-alkyl-4-piperidinylmethanolates. They were
