应用领域
制备方法
90g化合物(I)溶于500ml苯中,在冷却和搅拌下,于1h内加入92g过苯甲酸在1000ml苯中的溶液,在室温下放置5h。反应液用冰冷却过的氢氧化钠溶液洗,然后水洗,无水硫酸镁干燥。减压浓缩,剩余物用乙醚重结晶,得80g化合物(Ⅱ),收率81%,熔点182~184℃。
20g化合物(Ⅱ)溶于100ml N-甲基哌嗪和30ml水的混合液,在氮气中回流70h。减压蒸出过量的N-甲基哌嗪,剩余物和2倍量的乙腈混合,沸腾回流数分钟。冷至0℃,过滤析出的白色结晶,真空干燥至恒重,得19g化合物(Ⅲ),收率63%,熔点199~201℃。
10.6g化合物(Ⅲ)溶于50ml四氢呋喃和50ml甲醇的混合液,加入9g过量的硼氢化钠,搅拌6h。减压蒸出溶剂,剩余物溶于氯仿。先用2%氢氧化钠溶液洗,然后用水洗。干燥后蒸出溶剂,剩余物用氯仿和丙酮混合液重结晶,得9.3g化合物(Ⅳ),收率91%,熔点264~267℃。
5.8g化合物(Ⅳ)溶于20ml乙酸酐和5ml乙酸的混合液,加入0.5g氯化锌,在室温下搅拌3h。反应液倾人250ml水,于0℃放置。过滤出沉淀,溶于乙醚,用水洗至中性。蒸去溶剂,再用正己烷重结晶,得5g化合物(V),收率71%,熔点128~130℃。
37.4g化合物(V)和16g溴甲烷溶于1300ml丙酮,在室温下保持30h。过滤析出的结晶,用二氯甲烷和丙酮的混合液来提纯,得48g哌库溴铵,收率92%,熔点262~264℃(分解)。
最后一步反应如下。4g化合物(V)溶于40ml二氯甲烷和20ml硝基甲烷的混合液中,加入9ml溴甲烷。在压力管中于室温下放置2d。过滤除去三甲基化的溴化物副产物。滤液用乙醚稀释,过滤形成的固体,用二氯甲烷和乙醚混合液重结晶,得哌库溴铵。

nAChR
Sugammadex has a high affinity for Pipecuronium bromide. As Pipecuronium bromide is about 6 to 7 times more potent than Rocuronium, fewer molecules are required to achieve a comparative blockade than in the case of Rocuronium.
The average ED
95
is 0.045mg/kg (0.035-0.059 mg/kg) of Pipecuronium bromide, the onset of action varies between 2 and 6.3 minutes, depending on the dose and the background anesthesia. Pipecuronium bromide does not liberate histamine, it has no cardiovascular side effects even in doses of 3× ED
95
, and anaphylaxis does not appear to be a problem.
