Phosphorylated retinoids were synthesized by a modification of the procedure that Popják et al. (Popják, G., Cornforth, J. W., Cornforth, R. H., Ryhage, R., and Goodman, D. S. (1962) J. Biol. Chem. 237, 56-61) used to synthesize farnesylpyrophosphate. The all-trans-beta-retinyl phosphate; all-trans-9-(4-methoxy-2,3,6-trimethylphenyl)-3,7-dimethyl-2,4,6,8-nonatetraene-1-yl phosphate; perhydromonoeneretinyl phosphate; all-trans-beta-retinoyl phosphate; 13-cis-beta-retinoyl phosphate derivatives were tested as acceptors of [14C]mannose from GDP-[14C]mannose in a reaction catalyzed by rat liver membranes. The phosphate esters all functioned as acceptors of mannose to give a product chromatographically indistinguishable from endogenous mannosylretinyl phosphate. The mixed anhydrides, however, did not function as mannosyl acceptors. Neither class of compounds had any effect on the biosynthesis of dolichylmannosyl phosphate. Rat liver membranes did not catalyze the transfer of [14C]galactose from UDP-[14C]galactose to retinyl phosphate even at a concentration of retinyl phosphate (0.73 mM) which stimulated formation o mannosylretinyl phosphate by more than 50-fold...
磷酸化视黄醇通过对Popják等人(Popják, G., Cornforth, J. W., Cornforth, R. H., Ryhage, R., and Goodman, D. S. (1962) J. Biol. Chem. 237, 56 - 61)用于合成法呢基焦磷酸的方法进行改进来合成。全反式-β-视黄醇磷酸酯;全反式-9-(4-甲氧基-2,3,6-三甲基苯基)-3,7-二甲基-2,4,6,8-壬四烯-1-基磷酸酯;全氢单烯视黄醇磷酸酯;全反式-β-视黄酰磷酸酯;13-顺式-β-视黄酰磷酸酯衍生物在大鼠肝细胞膜催化的反应中作为GDP-[14C]甘露糖中[14C]甘露糖的受体进行了测试。这些磷酸酯均作为甘露糖的受体,产生一种在色谱上与内源性甘露糖基视黄醇磷酸酯无法区分的产物。然而,混合酸酐并不作为甘露糖基受体起作用。这两类化合物对磷酸多萜醇甘露糖的生物合成均无任何影响。即使在视黄醇磷酸酯浓度为0.73 mM(该浓度能使甘露糖基视黄醇磷酸酯的形成增加50倍以上)时,大鼠肝细胞膜也不催化UDP-[14C]半乳糖中[14C]半乳糖向视黄醇磷酸酯的转移……
