This invention discloses a binary
phthalocyanine exhibiting type I
photosensitivity and photothermal synergistic effects, its preparation, and its applications. The binary
phthalocyanine is a
silicon phthalocyanine-
zinc phthalocyanine
coupling compound or a
zinc phthalocyanine-
zinc phthalocyanine
coupling compound, which can self-assemble in water. In water, the self-assembled binary phthalocyanine not only produces an effective type I
photosensitivity reaction but also generates a
photothermal effect, thus it can be used as a
photosensitizer, photothermal agent, or photodynamic-photothermal combined
drug. Furthermore, when used as a photodynamic-photothermal combined
drug, it can generate a high amount of
superoxide anions and a significant
photothermal effect under near-
infrared laser irradiation and hypoxic conditions, meaning it has high anticancer activity under both aerobic and anaerobic conditions, showing significant application prospects in the treatment of hypoxic tumors. In addition,
in vivo experiments have demonstrated that the binary phthalocyanine can be cleared by the kidneys and excreted in
urine, effectively avoiding potential biotoxicity caused by
drug accumulation
after treatment, thereby significantly improving
biosafety.
