A convergent synthesis of SylA was developed and consists of the synthesis of a fully functionalized macrocycle, which is subsequently coupled with a urea moiety. For cyclization, ring-closing metathesis of a conformationally preorganized precursor was employed. The established synthetic route was then applied to the synthesis of SylA derivatives by using various peptidic side chains for decoration
开发了 SylA 的会聚合成,由全功能化大环的合成组成,随后与尿素部分偶联。对于环化,采用构象预组织前体的闭环复分解。然后通过使用各种肽侧链修饰SylA大环,将建立的合成路线应用于SylA衍生物的合成。对所得的 SylA 类似物集合进行了蛋白酶体抑制测试,表明聚乙二醇化 SylA 衍生物是最有效的蛋白酶体抑制剂。
