經由唾液酸化而來的醣蛋白及醣脂質，存在於細胞表面，對於癌 細胞的轉移扮演著相當重要的角色。根據文獻報導醣類、核甘酸及醣 類衍生物的抑制性，針對以予體為基礎的抑制劑，發現核甘酸結構有 其存在的必要性，而唾液酸部分則不一定。基於這些已知的預測奎寧 酸─核甘單磷酸將對唾液酸轉移酶有其抑制效果，因此設計合成以 Fmoc-Asp(OBut)-OH 或Fmoc-Glu(OBut)-OH 為鏈鍵之奎寧酸─核甘 單磷酸類似物。 Sialylation of glycoproteins and glycolipids, which plays an important role in cell surface to cancer cell metastasis. The literatures reported that inhinitors including saccharid, nucleotide, and sugar derivatives displayed the importance and requirement of the cytidine nucleotide toward the inhibition of sialyltransferase, but the sialic acid moiety may not be essential. Base on these report evidence, the non-sialyl framework CMP-quinic acid derivatives will be effective inhibitors of sialyltransferases. Therefore, we utilize such as Fmoc-Asp(OBut)-OH or Fmoc-Glu(OBut)-OH to construct the synthesis of quinic acid-CMP analogues.
