  Investigation of B,C-ring truncated deguelin derivatives as heat shock protein 90 (HSP90) inhibitors for use as anti-breast cancer agents

  摘要：

  On the basis of deguelin, a series of the B, C-ring truncated surrogates with N-substituted amide linkers were investigated as HSP90 inhibitors. The structure activity relationship of the template was studied by incorporating various substitutions on the nitrogen of the amide linker and examining their HIF-1 alpha inhibition. Among them, compound 57 showed potent HIF-1 alpha inhibition and cytotoxicity in triple-negative breast cancer lines in a dose-dependent manner. Compound 57 downregulated expression and phosphorylation of major client proteins of HSP90 including AKT, ERK and STAT3, indicating that its antitumor activity was derived from the inhibition of HSP90 function. The molecular modeling of 57 demonstrated that 57 bound well to the C-terminal ATP-binding pocket in the open conformation of the hHSP90 homodimer with hydrogen bonding and pi-cation interactions. Overall, compound 57 is a potential antitumor agent for triple-negative breast cancer as a HSP90 Cterminal inhibitor.

• Photoinduced Reduction of Nitroarenes and Tandem C–N Cross-Coupling with Haloarenes
  作者：Haoshi Bao、Leifeng Wang

  DOI：10.1021/acs.orglett.3c03656

  日期：2023.12.15

  photocatalytic C–N cross-coupling of nitroarenes with haloarenes has been developed using simple and cheap Ni(acac)2 as a cocatalyst. The reaction is confirmed as a stepwise process: (1) metal free photoinduced reduction of nitroarenes into aniline derivatives and (2) photo- and Ni-catalyzed C–N cross-coupling of anilines with haloarenes. The reaction conditions are simple and mild, giving high-value diarylamines

  使用简单且廉价的 Ni(acac) 2作为助催化剂，开发了硝基芳烃与卤代芳烃的高效光催化 C-N 交叉偶联。该反应被证实是一个逐步过程：（1）无金属光诱导硝基芳烃还原成苯胺衍生物，（2）苯胺与卤代芳烃的光催化和镍催化C-N交叉偶联。反应条件简单温和，可得到高价值的二芳基胺，具有良好的收率和良好的官能团耐受性。
