Selenium plays an important role in treating diseases, but current selenium delivery systems face challenges. Researchers have created a reactive organic selenium delivery platform by activating HOCl to release hypochloroselenoite derivatives with higher reactivity. These compounds can react with various nucleophiles and participate in specific life processes, making it significant for expanding the application of selenium-containing compounds and treating related diseases.
Selenium plays an important role in the biological system and can be used to treat various types of diseases. However, the current selenium delivery systems face the problems of low activity of released Se-containing compounds or nonspecific toxicity of reactive organic selenium donors in living systems. In response to these problems, we constructed a reactive organic selenium delivery platform by the activation of HOCl. Compared with prodrugs without activation capability, the hypochloroselenoite derivatives released from the present platform after activation displayed higher reactivity and could react with various nucleophiles to participate in specific life processes. Taking the selected compound (DHU-Se1) as an example, we found that it could alleviate the process of inflammation by blocking the polarization of macrophages from M0 to M1. Therefore, the development of this system is of great significance for expanding the application of selenium-containing compounds and treating related diseases.
