DNA 编码库 (DEL) 筛选已成为为药物发现应用寻找生物靶标小分子结合物的关键技术。开发新的 DNA 兼容化学物质以扩大可访问的 DEL 化学空间对于提高广泛目标类别和模式的筛选成功率至关重要。此外,使用常用构建块的反应以及启用 fsp 3的反应图书馆成员的增加将对访问各种类似药物的结构产生重大影响。在此,我们报告了一种与 DNA 相容的 Giese 型加成,即由预活化醇脱氧生成的非稳定 C 中心自由基生成 DNA 烯烃。尽管醇在 DEL 合成中一直未被充分用作构建单元类,但它们对黄原酸盐的活化使 Csp 3 –Csp 3偶联以提供富含 sp 3的产品。该反应与多类官能团相容,不破坏DNA标签,适用于DEL生产。

The present invention relates to dihydropyrrole compounds of Formula (I) that are useful for treating cellular proliferative diseases, for treating disorders associated with KSP kinesin activity, and for inhibiting KSP kinesin. The invention is also related to compositions which comprise these compounds, and methods of using them to treat cancer in mammals.
The present invention is directed to the identification, characterization and three-dimensional structure of a novel ligand binding site of KSP. Binding of ligands to the novel binding site result in a conformational change in the three-dimensional structure of the protein and a modulation of the activity of KSP. This conformational change in turn results in the formation of a novel binding pocket in the KSP protein, which comprises the novel binding site of the instant invention.
