The synthesis of a seven-membered ring locked analogue of 11-cis-retinol, tethered to a cross-linking moiety on C-15 and a lysine-extended biotin on the C-3, was accomplished for its utilization as a probe to fish out retinol binding proteins that may be involved in the reisomerization of retinal from all-trans to 11-cis in the visual cycle.Key words: retinoids, biotin, 11-cis-locked, cross-linking, retinol binding proteins.
我们合成了 11-顺式视黄醇的七元锁环类似物,它与 C-15 上的交联分子和 C-3 上的赖氨酸延伸生物素相连,可用作视黄醇结合蛋白的探针,这些蛋白可能参与了视黄醇在视觉周期中从全反式到 11-顺式的再异构化。
