Variable-temperature proton nuclear magnetic resonance studies have shown that 5-(2-propylidene)-10-(4-methylpiperazino)-5H-dibenzo[a,d] cycloheptene, a 5,11-dicarbo analogue of the atypical neuroleptic agent clozapine [8-chloro-11-(4-methylpiperazino)-5H-dibenzo[b,e][1,4]diazepine], exists as thermally stable configurational isomers. The presence of the 2-propylidene group at C-5 on the 5H-dibenzo[a
变温质子核磁共振研究表明,5-(2-亚丙基)-10-(4-甲基哌嗪子基)-5H-二苯并[a,d]环庚烯是一种非典型抗精神病药氯氮平的5,11-二苯并类似物[8-氯-11-(4-甲基哌嗪子)-5H-二苯并[b,e] [1,4]二氮杂]以热稳定的构型异构体形式存在。与氯氮平相比,在5H-二苯并[a,d]环庚烯部分的C-5处存在2-亚丙基对氯氮平的这种5,11-二苯并类似物在体外的亲和力没有太大的干扰。鼠脑中毒蕈碱和多巴胺D-1和D-2的结合位点。由于5H-二苯并[b,e] [1,4]二氮杂moiety部分上氯取代基的存在和位置对与氯氮平有关的1,4-二氮杂pine的各自结合亲和力有显着影响,因此氯取代5 制备了氯氮平的11-dicarbo类似物,以进一步检查结构-活性关系。与氯氮平和氯氮平的其他5H-二苯并[b,e] [1,4]二氮杂analogue类似物相比,评估这些类似物与毒蕈碱和多巴胺结
