Enediyne Derivatives

A novel class of synthetic substances that exhibits DNA cleavage and anticancer activity is discovered. Enediyne is a well-known anticancer agent. Mechanistic study on the new invention confirms that these synthetic substances are converted into enediynes under physiological condition and then deliver enediyne-like biological activity. Compared with enediyne, these substances possess higher chemical stability at room temperature and can therefore be used as enediyne prodrugs. Several synthetic processes were developed for these substances and their DNA cleavage capability and their cytotoxicity against cancer cell lines were evaluated. The results confirm that the substances are of potential value for developing into novel anticancer agents.
Technology Benefits
1. Heat-liable
2. Chemically stable at room temperature
3. Easy to be handled
Technology Application
- A potential replacement of the anticancer drug enediyne
