the GLUT1 transporter of the human erythrocytes. All four compounds were able to inhibit [14C]glucose uptake in a concentration-dependent manner. One of them, compound 6, exhibited an approximately 160-fold higher inhibition of [14C]glucose uptake by the GLUT1 transporter than glucose itself. Compound 6 was also able to inhibit [3H]cytochalasin B binding to erythrocytes with approximately 1000-fold
对脑内肿瘤使用化学治疗剂的局限性在于它们对中枢神经系统的吸收不良。增强大脑输送能力的一种方法是设计通过血脑屏障的饱和营养载体之一,高效的大脑和红细胞葡萄糖转运蛋白同工型GLUT1输送到大脑中的药物。由于血脑屏障的GLUT1己糖转运蛋白也存在于红细胞上,因此设计用于由GLUT1转运蛋白转运的新化合物已在人红细胞上进行了研究,它们代表了独特的,易于获得的人GLUT1表达细胞。在本文中,我们描述了四种葡萄糖-苯丁酸氮芥衍生物的合成,即甲基6-O-4 [双(2-氯乙基)氨基]苯丁酸酯和酰基-β-D-吡喃葡萄糖苷(3),6-O-4- [双(2-氯乙基)氨基]苯磺酰基-D-吡喃葡萄糖(6),甲基6- [4- [双(2-氯乙基)氨基]苯丁酰基an] -6-脱氧-β- D-吡喃葡萄糖苷(9)和6- [4- [双(2-氯乙基)氨基]苯丁酰氨基酰胺基] -6-脱氧-D-吡喃葡萄糖(10),以及它们与人类GLU
