Abstract
Minimally invasive photodynamic therapy, destroying lesions with a light-activated photosensitizer, has been increasingly performed since it is highly efficiency, safe, synergistically compatible, repeatable, and minimally-invasive, with few adverse reactions. However, the most present
photosensitizer or nanodrug delivery system containing a photosensitizer can target tumor cells but rarely cell nuclei. In this regard, the nucleus-targeting drug delivery system has been developed aiming impair tumor cells in an efficient and direct manner. In this study, the cationic liposome
(Clip) drug delivery system integrated with low dose nucleus-targeting chemotherapeutic drug Doxorubicin (DOX) and photosensitizer AlPcS4 (Clip-AlPcS4@DOX) was synthesized. Among them, Clip was used to efficiently load drugs into cells almost at the same time, low dose DOX was used to open
the channel for the materials to enter the nucleus on the premise of ensuring low cytotoxicity and then introduced photosensitizer into the nucleus, AlPcS4 photosensitizer was used to damage directly and efficiently through the photodynamic therapy (PDT) effect after entering the nucleus.
In summary, a nucleus-targeting nanodrug delivery system (Clip-AlPcS4@DOX) was designed and synthesized and could be induced cell apoptosis more quickly and efficiently. Therefore, it could be a promising nucleus-targeting nanosized reagent integrating the PDT and chemotherapy for gastric
therapy.
