overexpression is a signature of some cancer types, thus suggesting that fucosidase‐targetted ligands could play the role of drug‐delivery vectors. Herein, we describe the synthesis of a new series of pyrrolidine–ferrocene conjugates, consisting of a L‐fuco‐configured dihydroxypyrrolidine as the fucosidase ligand armed with a cytotoxic ferrocenylamine moeity. Three‐dimensional structures of several of these fucosidase
通过岩藻糖苷酶过表达增强岩藻糖的代谢是某些类型癌症的标志,因此表明以岩藻糖苷酶为靶标的配体可以发挥药物递送载体的作用。在这里,我们描述了一系列新的吡咯烷-二茂铁结合物的合成,该结合物由L - fuco构型的二羟基吡咯烷作为岩藻糖苷酶配体组成,具有细胞毒性二茂铁基胺部分。这些岩藻糖苷酶抑制剂中的几种的三维结构揭示了模拟3 E的过渡态构象。用二茂铁基部分进行精制会产生牛和细菌岩藻糖苷酶的亚微摩尔抑制剂,后者的3D结构显示出电子密度高,表明烷基二茂铁化合物具有高度的移动性。最好的化合物表现出很强的抗增殖作用,具有高达MDA-MB-231癌细胞的增殖抑制率为100%,在50μ中号。
