Improving therapeutics delivery in enzyme replacement therapy (ERT) for lysosomal storage disorders is a challenge. Herein, we present the synthesis of novel analogues of mannose 6‐phosphate (M6P), known as AMFAs and functionalized at the anomeric position for enzyme grafting. AMFAs are non‐phosphate serum‐resistant derivatives that efficiently bind the cation‐independent mannose 6‐phosphate receptor
在针对溶酶体贮积症的酶替代疗法(ERT)中改善治疗药物的传递是一项挑战。在这里,我们介绍了新型的甘露糖6-磷酸(M6P)类似物的合成,称为AMFAs,并在异头位置进行了酶接枝功能化。AMFA是非磷酸盐血清抗性衍生物,可有效结合不依赖阳离子的甘露糖6磷酸受体(CI-M6PR),这是将酶处理到溶酶体的主要途径。一种AMFA被用于改善溶酶体肌病Pompe疾病的治疗,在该疾病中酸性α-葡萄糖苷酶(GAA)存在缺陷。与Myozyme M6P重组GAA相比,AMFA嫁接在不含M6P的重组GAA上导致培养的成年Pompe成纤维细胞对GAA的吸收更高。而且,
