Triacetyl ribose yog ib qho tseem ceeb nruab nrab rau kev sib txuas ntawm capecitabine, thiab capecitabine tshuaj feem ntau tuaj yeem npaj nyob rau hauv peb kauj ruam dhau los ntawm txoj kev qhia hauv cov ntawv nyeem. Raws li cov lus ceeb toom hauv cov ntawv nyeem, kev sib txuas ntawm triacetyl ribose feem ntau yog ua raws li ob txoj hauv qab no: ib qho yog siv 1-methyl-5-deoxyribose raws li ib nrab, thiab triacetyl ribose tau los ntawm kev ua ob kauj ruam; qhov thib ob yog siv 5-deoxy-D -Ribose yog ib nrab thiab triacetyl ribose yog tau los ntawm ib-qib acetylation. Raws li cov txheej txheem hluavtaws tau tshaj saud, kev npaj khomob triacetyl ribose yog sib xyaw ntawm α thiab om isomers. Lub β isomer koom rau hauv cov tshuaj tiv thaiv tom ntej los npaj Capecitabine. Tus isomer yog tus impurity uas ua, thiab tus α sib txawv. Qhov ntsuas ntawm qhov qauv yog 3 ~ 30%, thiab qhov sib piv ntawm α isomer yuav tsis siab dua. Tus ntshiab β isomer tuaj yeem tau los ntawm kem chromatography lossis recrystallization ntawm no isomer piv.
