trioxacarcins是多氧的、结构复杂的天然产物,其有效地抑制培养的人类癌细胞的生长。在这里,我们描述了合成trioxacarcin A,DC-45-A1,和结构类似物的后期,立体选择性糖基化反应的完全功能化,差异保护苷元底物。在这项工作中解决的关键问题包括确定一个适当的手段,以激活和保护每两个2-脱氧糖组分,trioxacarcinose A和trioxacarcinose B,以及一个可行的糖苷偶联测序。我们提出的收敛的,基于组件的序列允许快速构建结构多样的合成类似物,这些类似物是通过任何其他手段无法获得的,其数量需要支持生物学评价。从五个模块化组件中的四个修改产生的类似物在11个步骤或更少的步骤中组装。发现这些中的大多数在使用培养的人癌细胞的抗增殖测定中具有活性。
The trioxacarcins are polyoxygenated, structurally complex natural products that potently inhibit the growth of cultured human cancer cells. Here we describe syntheses of trioxacarcin A, DC-45-A1, and structural analogs by latestage, stereoselective glycosylation reactions of fully functionalized, differentially protected aglycon substrates. Key issues addressed in this work include the identification of an appropriate means to activate and protect each of the two 2-deoxysugar components, trioxacarcinose A and trioxacarcinose B, as well as a viable sequencing of the glycosidic couplings. The convergent, component-based sequence we present allows for rapid construction of structurally diverse, synthetic analogs that would be inaccessible by any other means, in amounts required to support biological evaluation. Analogs arising from modification of four of five modular components are assembled in 11 steps or fewer. The majority of these are found to be active in antiproliferative assays using cultured human cancer cells.
