摘要 为更好控制阿普斯特产品质量,依据阿普斯特的结构特征与合成工艺,分别合成了其4个可能有关物质,分别为异构体杂质((R)-2-[1-(3-乙氧基-4-甲氧基苯基)-2-甲磺酰基乙基]-4-乙酰基氨基异吲哚啉-1,3-二酮)、有关物质A((S)-2-[1-(3-乙氧基-4-甲氧基苯基)-2-甲磺酰基乙基]-4-硝基异吲哚啉-1,3-二酮)、有关物质B((S)-2-[1-(3-乙氧基-4-甲氧基苯基)-2-甲磺酰基乙基]-4-氨基异吲哚啉-1,3-二酮)、有关物质H((S)-2-[1-(3-乙氧基-4-甲氧基苯基)-2-甲磺酰基乙基]-4-(4-乙酰基氨基异吲哚啉-1,3-二酮)异吲哚啉-1,3-二酮)),并对其结构通过1H-NMR进行了确证,可作为阿普斯特质量标准研究参照。 According to the structural characteristics of Apremilast and its synthetic process, four related substances: isomer impurity((R)-N-(2-(1-(3-ethoxy-4-methoxyphenyl)-2-(methylsulfonyl) ethyl)-1,3-dioxoisoindolin-4-yl)acetamide), impurity A((S)-2-(1-(3-ethoxy-4-methoxyphenyl)-2-(methylsulfonyl)ethyl)-4-nitroisoindoline-1,3-dione), impurity B((S)-4-amino-2-(1-(3-ethoxy-4-methoxyphenyl)-2-(methylsulfonyl)ethyl)isoindoline-1,3-dione), impurity H((S)-N-(2-(2-(1-(3- ethoxy-4-methoxyphenyl)-2-(methylsulfonyl)ethyl)-1,3-dioxoisoindolin-4-yl)-1,3-dioxoisoindolin-4-yl)acetamide), were synthesized,confirmed by 1H-NMR, These substances were taken as the references for the quality control of Apremilast.
