  3-Phenyl-Substituted Imidazo[1,5-a]quinoxalin-4-ones and Imidazo[1,5-a]quinoxaline Ureas That Have High Affinity at the GABA_A/Benzodiazepine Receptor Complex

  摘要：

  A series of imidazo[1,5-alpha]quinoxalin-4-ones and imidazo[1,5-alpha]quinoxaline ureas containing substituted phenyl groups at the 3-position was developed. Compounds within the imidazo-[1,5-alpha]quinoxaline urea series had high affinity for the GABA(A)/benzodiazepine receptor complex with varying in vitro efficacy, although most analogs were partial agonists as indicated by [S-35]TBPS and Cl- current ratios. Interestingly, a subseries of piperazine ureas was identified which had biphasic efficacy, becoming more antagonistic with increasing concentration. Analogs within the imidazo [1,5-alpha] quinoxalin-4-one series had substantially decreased binding affinity as compared to the quinoxaline urea series. These compounds ranged from antagonists to full agonists by in. vitro analysis, with several derivatives having roughly 4-fold greater intrinsic activity than diazepam as indicated by Cl- current measurement. Numerous compounds from both series were effective in antagonizing metrazole-induced seizures, consistent with anti-convulsant properties and possible anxiolytic activity. Most of the quinoxaline ureas and quinoxalin-4-ones were active in an acute electroshock physical dependence side effect assay in mice precluding further development.

  reversal of the pharmacological activity due only to a small structural difference might confirm the existence of two binding sites on the 5-HT(4) receptor. In the alkylene spacer, a two-methylene chain is favorable to optimize the affinity and the antagonist or the partial agonist activity. In the ethyl and cyclopropyl series, 5-HT(4) antagonist activity seems to be unrelated to the size of the 4-substituent
