  High-Affinity Partial Agonist Imidazo[1,5-a]quinoxaline Amides, Carbamates, and Ureas at the γ-Aminobutyric Acid A/Benzodiazepine Receptor Complex

  摘要：

  A series of imidazo[1,5-alpha]quinoxaline amides, carbamates, and ureas which have high affinity for the gamma-aminobutyric acid A/benzodiazepine receptor complex was developed. Compounds within this class have varying efficacies racing from antagonists to full agonists. However, most analogs were found to be partial agonists as indicated by [S-35]TBPS and Cl- current ratios. Many of these compounds were also effective in antagonizing metrazole-induced seizures in accordance with anticonvulsant and possible anxiolytic activity. Selected quinoxalines displayed limited benzodiazepine-type side effects such as ethanol potentiation and physical dependence in animal models. Dimethylamino urea 41 emerged as the most interesting analog, having a partial agonist profile in vitro while possessing useful activity in animal models of anxiety such as the Vogel and Geller assays. In accordance with its partial agonist profile, 41 was devoid of typical benzodiazepine side effects.

  carbamates, represent a new series of compounds which bind with high affinity to the GABAA/benzodiazepine receptor. These compounds exhibit a wide range of intrinsic efficacies as measured by [35S]TBPS binding ratios. The synthesis of 1a begins with the addition of DL-glutamic acid to 1-fluoro-2-nitrobenzene, followed by reduction of the nitro group and subsequent ring closure to form 3-(carbethoxymethyl)-1
