目的改进盐酸环苯扎林的合成方法。方法以二苯并环庚烯酮为起始原料,与3-(N,N-二甲基氨基)氯丙烷经格氏反应生成5-(3-二甲氨基丙基)-5-羟基二苯并环庚三烯,后经稀盐酸脱水生成环苯扎林,最终与氯化氢乙酸乙酯溶液生成盐酸环苯扎林。结果与结论目标化合物及中间体的结构经1H-NMR、ESI-MS谱等确证,HPLC法检测纯度达99.70%,单个杂质含量小于0.1%。新合成路线操作简便,反应条件温和。使用的原料和试剂成本都比较低廉,总收率为50%,适合工业化生产。 相似文献

The clinical findings in three patients who ingested 260-900 mg cyclobenzaprine (Flexeril) consisted of delayed onset and long duration of anticholinergic symptomatology. In two of these patients, symptoms responded to treatment with physostigmine. The third patient recovered without specific therapy. Despite its structural similarity to amitriptyline, cyclobenzaprine overdosage did not result in coma, seizures, or cardiac toxicity. The pharmacological properties of cyclobenzaprine may account for the observed toxicity. 相似文献

The effects of cyclobenzaprine, a tricyclic compound, on the central depressant action of ethanol and on hepatic ethanol metabolizing enzymes were studied in rodents. Administration of cyclobenzaprine, 5 mg/kg, IP, 30 min prior to a narcotic dose of ethanol solution, 5 g/kg, IP, enhanced ethanol-produced narcosis in mice. This effect was greater in male than in female mice. Cyclobenzaprine inhibited endogenous rat liver alcohol dehydrogenase in vitro in the concentration range between 10−5M and 10−6M. Cyclobenzaprine exerted little effect on hepatic aldehyde dehydrogenase in vitro. The results suggest that cyclobenzaprine possesses depressant properties and inhibition of liver alcohol dehydrogenase may underlie the observed behavioral response studied. It is concluded that alteration of endogenous liver alcohol dehydrogenase by certain tricyclic antidepressant drugs may be involved in the mechanism(s) of their toxic interaction with ethanol. 相似文献
