What is Laser/GSH-Activatable Oxaliplatin/Phthalocyanine-Based Coordination Polymer Nanoparticles Combining Chemophotodynamic Therapy to Improve Cancer Immunotherapy about?
There are two severe obstacles in cancer immunotherapy. The first is that the low response rate challenges the immune response owing to the immunosuppressive tumor microenvironment (ITM) and poor immunogenicity of the tumor. The second obstacle is that the dense and intricate pathophysiology barrier seriously restricts deep drug delivery in solid tumors. A laser/glutathione (GSH)-activatable nanosystem with tumor penetration for achieving highly efficient immunotherapy is reported. The core of the nanosystem was synthesized by coordinating zinc ions with GSH-activatable oxaliplatin (OXA) prodrugs and carboxylated phthalocyanine. Such an OXA/phthalocyanine-based coordination polymer nanoparticle (OPCPN) was wrapped by a phospholipid bilayer and NTKPEG. NTKPEG is a PEGylated indoleamine 2,3-dioxygenase 1 (IDO1) inhibitor prodrug containing a thioketal (TK) linker, which was modified on the OPCPN (OPCPN@NTKPEG). Upon the laser irradiation tumor site, ROS production of the OPCPN@NTKPEG triggers cleavage of NTKPEG by degradation of TK for promoted tumor penetration and uptake. OXA, phthalocyanine, and IDO1 inhibitor were released by the intracellular high-level GSH. OXA inhibits cell gr
