Conjugation of 4,5-Epoxymorphinan-6-ols with Bromoglucuronides in the presence of Zinc containing compounds as activator under conditions capable of forming 4,5-Epoxymorphinan-6-oxyglucuronides is disclosed. This novel approach provides an efficient method for preparation of both anomers of 4,5-Epoxymorphinan-6-oxyglucuronides. The deprotected end products are useful as analgesic agents.

Morphine‐6β‐D‐glucuronide (M6βG), an active metabolite of morphine, and its isomer morphine‐6α‐D‐glucuronide (M6αG) were synthesized from 3‐O‐protected morphinethrough glycosylation and alkaline hydrolysis. All structures were determined by spectroscopic analysis, and especially it is the first time to report the single crystal of compound M6αG. In vitro binding assay showed that M6βG bound to mu opioid
吗啡的活性代谢物吗啡-6β-D-葡糖醛酸(M6βG)及其异构体吗啡-6α-D-葡糖醛酸苷(M6αG)是通过3-O-保护的吗啡通过糖基化和碱性水解合成的。所有结构均通过光谱分析确定,尤其是首次报道了化合物M6αG的单晶。体外结合试验表明M6βG以纳摩尔亲和力(K i = 28.03、116.88和375.13 nM)与mu阿片受体(MOR),κ阿片受体(KOR)和δ阿片受体(DOR)结合,而M6αG与它们结合以相似的亲和力(ķ我= 1070.13、20 637.93和677.36 nM)。M6αG对KOR的选择性更高。热板试验表明,M6βG的镇痛作用优于M6αG,这可能是因为M6αG的作用机理不同。

A stereoselective synthesis of both isomers of the pharmaceutically important morphine 6-beta -D-glucuronide (M6G) and its analogs was developed. The method is based on the use of ZnBr2 for the key coupling reaction. It was shown that the alpha/beta stereoselectivity of the reaction can he directed and controlled by the amount of ZnBr2. This paper describes the synthesis, analysis and characterization of the Lu-isomer of M6C, useful as a reference marker for testing purity and stability of the morphine 6-beta -D-glucuronide (M6G).
