  描述：

  N-(tetrahydro-3,3-diphenyl-2-furylidene)methylamine hydrobromide 在 sodium hydroxide 作用下， 以 水 为溶剂， 生成 N-methyl-3,3-diphenyloxolan-2-imine

  名称：

  A high-yield route to synthesize the P-glycoprotein radioligand [ C]N-desmethyl-loperamide and its parent radioligand [ C]loperamide

  摘要：

  N-Desmethyl-loperamide and loperamide were synthesized from a, a-diphenyl-c-butyrolactone and 4-(4-chlorophenyl)-4-hydroxypiperidine in five and four steps with 8% and 16% overall yield, respectively. The amide precursor was synthesized from 4-bromo-2,2-diphenylbutyronitrile and 4-(4-chlorophenyl)-4-hydroxypiperidine in 2 steps with 21-57% overall yield. [C-11] N-Desmethyl-loperamide and [C-11] loperamide were prepared from their corresponding amide precursor and N-desmethyl-loperamide with [C-11] CH3OTf through N-[C-11] methylation and isolated by HPLC combined with solid-phase extraction (SPE) in 20-30% and 10-15% radiochemical yields, respectively, based on [C-11] CO2 and decay corrected to end of bombardment (EOB), with 370-740 GBq/lmol specific activity at EOB.

  Compositions and methods using the compositions for treatment of peripheral hyperalgesia are provided. The compositions contain an anti-hyperalgesia effective amount of one or more compounds that directly or indirectly interact with peripheral opiate receptors, but that do not, upon topical or local administration, elicit substantial central nervous system effects. The anti-diarrheal compound 4-(p-chlorophenyl)-4-hydroxy-N-N-dimethyl-.alpha.,.alpha.-diphenyl-1-piper idinebutyramide hydrochloride is preferred for use in the compositions and methods.
