Site-specific cleavage of nucleic acids by photoreactive conjugates
摘要:
在 DNA 中形成双链切割的过程包括提供一个反应混合物,其中包含具有第一链中断的双链 DNA,在第二链中定义了一个靶位点。该方法继续通过向反应混合物中添加选择自赖氨酸-烯二炔共轭物、赖氨酸-乙炔共轭物或两者的光反应性赖氨酸共轭物,以使赖氨酸共轭物足够时间结合到靶位点附近的 DNA。然后,用足够的电磁辐射照射反应混合物,以激活赖氨酸共轭物并切割靶位点附近的第二链。

An efficient intramolecularcyclization reaction was developed to achieve indenone derivatives. The substituted 1,5-diyenes were converted to the cooresponding indenones via a gold-catalyzed organic transformation and moderate to excellent yields of the title molecules were obatained via formation of two C=O and one C−C bonds under mild reaction condtions in one pot.
