The preparation of a Syringolin A/Glidobactin A hybrid (SylA–GlbA) consisting of a SylA macrocycle connected to the GlbA side chain and its potent proteasome targeting of all three proteasomal subsites is reported. The influence of the syrbactin macrocycle moiety on subsite selectivity is demonstrated.
报告制备了一种由连接到 GlbA 侧链的 SylA 大环组成的丁香菌素 A-Glidobactin A 混合物(SylA-GlbA),并对所有三个
蛋白酶体亚位进行了有效的
蛋白酶体靶向。研究证明了 SylA 大环对亚位点选择性的影响。
