Some synthetic applications of 2,3-Dichloro-N-phenylmaleimide: A novel synthesis of 2-phenylpyrrolo[3,4-b]quinoxaline-1,3-diones. I
摘要:
2,3-Dichloro-N-phenylmaleimide 2 undergoes nucleophilic substitution reactions by a variety of nucleophiles giving either monosubstituted 5 or disubstituted 3 products. Treatment of 5 with sodium azide at room temperature results in cyclization to the corresponding 2-phenylpyrrolo[3,4-b]quinoxaline-1,3-diones 6, while at higher temperatures 5 is reduced to the 2-amino-3-amino-N-phenylmaleimides 7.

reported a copper-catalyzed vinylamination of S-alkylisothiouronium salts with maleimide and organic amines with the assistance of FeCl3, enabling the preparation of structurally diverse aminoalkylthiolated maleimides and applying them to late-stage modification of pharmaceuticals. Importantly, this strategy makes it possible to introduce the SCD3 functional group into the maleimide skeleton by using the

the reaction between different amines and 4‐methoxyphenol for the synthesis of imidobenzenesulphonyl derivatives. These compounds were tested as antinociceptive agents using the writhing test on mice. Some compounds, when intraperitoneally injected, proved to be potent and dose‐related antinociceptives, being several times more active than many known reference drugs.

The present invention concerns methods and compositions involving inhibitors and enhancers of RAD51, a protein involved in homologous recombination. In some embodiments, the present invention concerns methods for stimulating homologous recombination, which has a number of significant research and clinical applications. In certain other embodiments, there are methods for protecting cells using a compound that enhances RAD51 activity. Such enhancers may also be employed to prevent or reduce damage to cells that may be caused by DNA damaging agents. In other embodiments, there are methods for sensitizing cells to the effects of DNA damaging agents, which can have particular applications for cancer patients. In some embodiments of the invention, the RAD51 enhancer or inhibitor is a small molecule that directly affects RAD51 activity, such as its ability to promote filament formation.
