Chloro- and methyl-substituted 10H-pyrazino[2,3-b][1,4]benzothiazines were prepared and their structures determined by 13C NMR and X-ray crystallographic analysis. Alkylation afforded the 10-[3-(dimethylamino)-1-propyl] derivatives, which were compared to chlorpromazine in receptor-binding assays, in vivo behavioral tests, and electrochemical oxidation studies. In this series, the 2-chloro compound
制备了氯和甲基取代的10H-吡嗪并[2,3-b] [1,4]苯并噻嗪,并通过13C NMR和X射线晶体学分析确定其结构。烷基化提供了10- [3-(二甲基氨基)-1-丙基]衍生物,这些衍生物在受体结合试验,体内行为试验和电化学氧化研究中与氯丙嗪进行了比较。在该系列中,2-氯化合物4c被证明是从结合位点置换[3H]双胍,[3H]阿扑吗啡和[3H]哌唑嗪放射性配体的最有效衍生物,在这方面的作用与氯丙嗪差不多。然而,在预测神经安定性活性的体内试验中,该研究的10H-吡嗪并[2,3-b] [1,4]苯并噻嗪均没有像氯丙嗪那样活跃。
