Abstract

Quantitative structure-activity relationships (QSAR) have been formulated for the activities of a series of benzodiazepines in rats. The lipophilic character of molecules was expressed by means of the chromatographic Rm values which were very well correlated with experimental or calculated log P values. The ideal lipophilic character for activity of benzodiazepines in the exploratory behavior test is not far from that of compounds acting in the central nervous system as unspecific depressant agents. The results of both the conflict and exploratory behavior studies might support the hypothesis of different sites of action for the antianxiety and sedative effects of benzodiazepines.

摘要

已经针对一系列苯二氮䓬类药物在大鼠体内的活性建立了定量构效关系（QSAR）。分子的亲脂性通过色谱Rm值来表示，该值与实验或计算得到的log P值具有很好的相关性。在探索行为测试中，苯二氮䓬类药物发挥活性的理想亲脂性与作为非特异性抑制剂作用于中枢神经系统的化合物的亲脂性相近。冲突和探索行为研究的结果可能支持苯二氮䓬类药物抗焦虑和镇静作用的不同作用位点假说。
