  Glucosyl dopamine (DA) derivatives may represent a new class of DA prodrugs that would interact with glucose transporter GLUT-1, present in the blood–brain barrier, and generate DA in the brain. Therefore, compounds bearing the sugar moiety linked to either the amino group or the catechol ring of DA through amide, ester, carbamate, peptide or glycosidic bonds were synthesized. The behavior of the compounds as prodrugs was monitored in different media and the affinity of the glycoconjugates for the glucose carrier GLUT-1 using human erythrocytes was also studied. Most of the compounds were markedly stable in buffer and plasma, and several compounds released DA when incubated with brain extracts and the rate was related to the bond linking DA with glucose. The new glucosyl conjugates substituted at the C-6 position of the sugar were more potent inhibitors of glucose transport when compared to C-1 and C-3 substituted derivatives. This work provides structure–activity information about the interaction of substituted glucose with the GLUT-1 transporter.

  葡萄糖多巴胺（DA）衍生物可能代表一类新型DA前药，它们与存在于血脑屏障中的葡萄糖转运体GLUT-1相互作用，并在脑内生成DA。因此，通过酰胺、酯、氨基甲酸酯、肽或糖苷键将糖部分连接到DA的氨基或儿茶酚环上的化合物被合成出来。监测了这些化合物在不同介质中的前药行为，并研究了糖 conjugate 对人体红细胞中葡萄糖载体GLUT-1的亲和力。大多数化合物在缓冲液和血浆中显著稳定，几种化合物在与脑提取物共孵育时释放DA，且速率与DA与葡萄糖之间的连接键相关。与C-1和C-3取代的衍生物相比，在糖的C-6位取代的新型葡萄糖 conjugate 对葡萄糖转运的抑制作用更强。这项工作提供了关于取代葡萄糖与GLUT-1转运体相互作用的结构-活性信息。
