| 摘 要： | 通过模拟磷酸连接的唾液酸胞苷单磷酸酯(CMP-Neu5Ac),本文设计并合成了一系列氨基甲酸酯类唾液酸转移酶抑制剂。利用基于含紫外官能团受体的唾液酸转移酶抑制活性评价方法对化合物进行活性评价,其中化合物15g显示出中等抑制活性。我们推测氨基甲酸酯有可能通过电子等排原理,替换CMP-Neu5Ac中的磷酸酯基团,改善其膜渗透性,从而改善抑制活性。 |

| Abstract: | A series of carbamate-containing sialyltransferase inhibitors were designed and synthesized to simulate phosphate-linkedCMP-Neu5Ac. Their inhibitory activities were assayed against recombinant human ST3Gal I and ST6Gal I by using the Schmidt’sHPLC-based assay. The synthetic compound 15g showed moderate inhibitory activity. These findings implied that carbamate might serve as a bioisosteric replacement for a phosphate group in sialyltransferase inhibitor design to improve the membrane permeability. |
