为改进皮质抑素 A 和相关结构的合成以及策略的基本逻辑和演变提供了完整的细节。嵌入关键杂金刚烷的高度功能化的皮质抑素 A 环是通过简单且可扩展的五步序列合成的。未活化甲基的化学选择性串联双卤化、溴环丙烷的还原断裂/捕获/消除和简便的化学选择性醚化反应提供了皮质抑素 A 核心,称为“皮质他汀酮”。用 Raney Ni 选择性还原 Δ(16)-烯烃提供了皮质抑素 A。通过这种可扩展且实用的途径,大量的皮质抑素、Δ(16)-皮质抑素 A(皮质抑素 A 的等效直接前体)及其相关类似物被为进一步的生物学研究做好准备。

marine steroid with highly selective and perhaps mechanistically unique antiangiogenic activity. Herein we report a synthesis of this natural product by way of “cortistatinone”, an intermediate ideally suited for investigating the key pharmacophore of the cortistatin family. The synthesis begins with a terrestrial steroid and traverses a route to cortistatin A through the discovery of unique chemical
皮质抑素 A 是一种海洋类固醇,具有高度选择性并且可能在机制上具有独特的抗血管生成活性。在本文中,我们报告了通过“可的他汀酮”合成这种天然产物,这是一种非常适合研究皮质他汀家族关键药效团的中间体。该合成从一种陆生类固醇开始,并通过发现独特的化学反应性,通过一条途径获得皮质抑素 A。具体来说,我们展示了第一个定向的、成对的 C-H 双氧化的例子,一个新的碎片级联以访问扩展的 B 环类固醇系统,一个化学选择性环化以安装皮质抑素家族的标志性氧杂环己烯,以及一个显着的选择性氢化反应,这应该会在未来合成皮质抑素和设计的类似物中得到广泛应用。

A process for forming one or the other of a 17-α-aryl or 17-β-aryl steroidal compound in diastereo excess is disclosed. The process utilizes a 17-keto steroid to form a Δ16-17-aryl-steroid compound or a 17-β-hydroxy-17-α-aryl steroid compound that are reduced or deoxygenated, respectively, in the presence of Raney nickel to form a 17-β-aryl- steroid or 17-α-aryl steroid, respectively, in a diastereo ratio of at least 3:1.
Methods for preventing or treating retroviral infection, such as human immunodeficiency virus, in vivo utilize transcriptional inhibitory compounds. These include cortistatin A and analogs of the cortistatin family.
