Natural Product Evodiamine with Borate Trigger Unit: Discovery of Potent Antitumor Agents against Colon Cancer
摘要:
In order to improve the antitumor potency of the natural product evodiamine, novel boron-containing evodiamine derivatives were designed by incorporating boronic acid and boronate as trigger units. Boronate derivative 13a could be triggered by reactive oxygen species (ROS) in the HCT116 colon cancer cell line and showed excellent antitumor activity in vitro and in vivo. It induced apoptosis in HCT116 cancer cells in a dose-dependent manner and cell growth arrest at the G2 phase.

ester probes are superior and sensitive than the self-immolative linker-containing probes in detecting traces of exogenous and endogenous levels of H2O2. The difference in probe efficiency was also dependent on the nature of fluorophore unit being used. Considering these aspects, our detailed studies reveal that the directly-linked boronate ester-based fluorescein probe 19 is the best probe for efficiently
开启荧光探针通常用于有效估计活性氧(例如H 2 O 2)。在本研究中,通过将硼酸酯基团与三种重要的荧光染料直接或通过自消灭性连接剂偶联,合理设计了三套不同的用于检测H 2 O 2的荧光探针。有趣的是,我们的结果表明,在检测痕量外源性和内源性H 2 O 2时,直接连接的硼酸酯探针比含自消灭性接头的探针优越且灵敏。。探针效率的差异还取决于所使用的荧光团单元的性质。考虑到这些方面,我们的详细研究表明,直接连接的基于硼酸酯的荧光素探针19是用于以很高的灵敏度水平有效地检测水性介质和细胞介质中H 2 O 2的最佳探针。在设计用于ROS的荧光传感器以及在与ROS相关的病理学中使用荧光传感器时,本观察结果将是有用的。

A series of self-immolative boronic ester protected methyl salicylates and metal-binding groups with various linking strategies have been investigated for their use in the design of matrix metalloproteinase proinhibitors.
Set forth herein, inter alia, are compositions and methods for treating diseases with prodrugs. Provided herein are prodrug compositions for inhibiting the function of proteins, compositions and methods for treating diseases associated with oxidative compounds, oxidatively-sensitive prodrugs of inhibitors of metalloproteases. and methods of inhibiting metalloproteases using oxidatively-sensitive prodrugs.
