  藤黄酸（IV）的研究：探索与IκB激酶-β（IKKβ）的构效关系

  摘要：

  以前，我们已经报道了一系列藤黄酸的类似物，并鉴定出了一种具有与藤黄酸相当的体外生长抑制作用的化合物。但是，尚未鉴定其靶蛋白以及靶上的关键药效​​基序。在本文中，我们报道藤黄酸及其类似物通过抑制TNFα/NF-κB途径的激活而抑制了IκB激酶-β（IKKβ）的活性，这反过来又诱导了A549和U251细胞凋亡。IKKβ可以作为藤黄酸的靶标之一。文章中仔细讨论了化合物的制备。笼中的4-氧杂-三环[4.3.1.0 3,7被认为是药效学支架的] dec-2-one蒽酮代表了一种有前途的癌症治疗剂和有用的针对NF-κB途径的探针。

• A novel and efficient route to the construction of the 4-oxa-tricyclo[4.3.1.0]decan-2-one scaffold

  A short and efficient route to the synthesis of 4-oxa-tricyclo[4.3.1.0]decan-2-one scaffold 12 in good yield is reported. Essential to the synthesis was the implementation of selective protection of the catechol system in xanthone 2 with Ph2CCl2 and MOM groups. Subsequently, a biomimetic tandem Claisen/Diels–Alder reaction occurred to produce the desired tricyclic scaffold 11a as a single isomer. A

  据报道，一种短而有效的途径以高收率合成了4-氧杂-三环[4.3.1.0]癸烷-2-酮骨架12。合成必不可少的是在具有Ph 2 CCl 2和MOM基团的蒽酮2中实现邻苯二酚系统的选择性保护。随后，发生了仿生串联的Claisen / Diels-Alder反应，生成了所需的三环骨架11a，为单一异构体。还提出了该转换的优良区域的合理化和立体选择性的建议。
• Synthesis, structure-activity relationship and in vitro pharmacodynamics of A-ring modified caged xanthones in a preclinical model of inflammatory breast cancer

  Inflammatory breast cancer (IBC) is a highly metastatic, lethal form of breast cancer that lacks targeted therapeutic strategies. Inspired by the promising cytotoxicity of gambogic acid and related caged xanthones in spheroids(MARY-X), an in vitro preclinical IBC model, we constructed a library of synthetic analogs and performed structure-activity relationship studies. The studies revealed that functionalizing the A-ring of the caged xanthone framework can significantly affect potency. Specifically, introduction of hydroxyl or fluorine groups at discrete positions of the A-ring leads to enhanced cytotoxicity at sub-micromolar concentrations. These compounds induce complete dissolution of spheroids(MARY-X) with subsequent apoptosis of both the peripherally- and centrally-located cells, proliferative and quiescent-prone (e.g. hypoxic), respectively. These results highlight the structural flexibility and pharmacological potential of the caged xanthone motif for the design of IBC-targeting therapeutics. (C) 2019 Elsevier Masson SAS.

• Total synthesis of aldehyde-containing Garcinia natural products isomorellin and gaudichaudione A

  The natural products, isomorellin and gaudichaudione A, with a 4-oxa-tricyclo[4.3.1.0(3,7)] dec-8-en-2-one scaffold were synthesized for the first time using an efficient method. The key improvement of this method was the simultaneous bisalkylation of 5,6-dihydroxyxanthone with the bulky 2-methylbutyne group. This method obviously shortened the synthetic route and enhanced the total yield. Four analogues named forbesione, desoxymorellin, desoxygaudichaudione A, and gambogin containing the same caged structure were prepared using this method. (C) 2011 Elsevier Ltd. All rights reserved.

  Previously we have reported a series of gambogic acid's analogs and have identified a compound that possessed comparable in vitro growth inhibitory effect as gambogic acid. However, their target protein as well as the key pharmacophoric motifs on the target have not been identified yet. Herein we report that gambogic acid and its analogs inhibit the activity of IκB Kinase-beta (IKKβ) through suppressing
