The amino acid‐containing lithocholic acids (LCA) represent a new class of human sialyltransferase (ST) inhibitors. In this study, we have reported their design, synthesis, and inhibitory activity against human STs. Among these derivatives, D‐Glu‐LCA 7, L‐Asp‐L‐Asp‐LCA 13, and L‐Asp‐L‐Asp‐Gly‐Gly‐LCA 22 with specific amino acid sequence were the most active ones with IC50 values of 2.3–5.6 and 4.2‐6
含氨基酸的石胆酸(LCA)代表了一类新的人类唾液酸转移酶(ST)抑制剂。在这项研究中,我们已经报道了它们对人ST的设计,合成和抑制活性。在这些衍生物中,d -Glu-LCA 7,大号-Asp-大号-Asp-LCA 13,和大号-Asp-大号-Asp -甘氨酸-甘氨酸- LCA 22与特定的氨基酸序列是最活跃的带IC 50分别朝向α-2,3-ST和α-2,6-ST的2.3-5.6和4.2-6.2μM值。当前的研究表明,新型ST抑制剂通过防止伤口闭合而不是直接发挥抗增殖作用来抑制乳腺癌细胞的细胞迁移。
