Sulfate conjugates of ubiquinone metabolites (Ia, Ib) and related compounds including 6-(10-hydroxydecyl)-2, 3-dimethoxy-5-methyl-1, 4-benzoquinone (idebenone, Id-10) were synthesized. Chemical shifts in the proton nuclear magnetic resonance (1H-NMR) spectra of the 1- and 4- sulfates were assigned by investigating differences in the low-field shifts between model compounds and the corresponding sulfates, and by regio-specific synthesis of the 4-sulfates.
合成了泛醌代谢物(Ia、Ib)和相关化合物(包括 6-(10-羟基癸基)-2,3-二甲氧基-5-甲基-1,4-苯醌(idebenone,Id-10))的硫酸盐轭合物。通过研究模型化合物和相应硫酸盐之间低场移位的差异,以及 4-硫酸盐的特定区域合成,确定了 1-和 4-硫酸盐质子核磁共振(1H-NMR)光谱中的化学位移。
