Problems solved by technology

However, most of the existing substituted phthalocyanine metal complexes have problems such as difficult synthesis, many side reactions, and difficult separation.
At the same time, there is an important problem that the targeting of phthalocyanine to tumor tissue is not ideal, so the research on the targeting of photosensitizers has become a hot research topic now.

Abstract

The invention discloses an erlotinib-phthalocyanine conjugate which targets anti-cancer molecules, and a preparation method as well as an application of the erlotinib-phthalocyanine conjugate. Through introducing erlotinib with a long alcoxyl chain into the periphery of the metal phthalocyanine large ring, the amphipathy, the biocompatibility and the targeting of photo-sensitizer can be increased. The phthalocyanine conjugate is not easy to aggregate, which is beneficial for improving cell uptake rate; meanwhile, the compound is simple in structure and is free from isomer, and the product is easy to purify accordingly. By adopting the compound, the targeting of the photo-sensitizer in photo-dynamics therapy is helpful to be enhanced, and the activity of the photo-sensitizer in photo-dynamics therapy can be enhanced at the same time. As the synthetic method provided by the invention is simple, the side reaction is small, the yield is relatively high, the raw material is easily available and the cost is low, and the preparation method is beneficial for industrial production.

Description

technical field [0001] The invention belongs to the field of synthesis of organic and metal coordination compounds, and relates to a targeted anti-cancer molecule erlotinib phthalocyanine conjugate and its preparation method and application. Background technique [0002] Phthalocyanine is a class of macrocyclic compounds with good photophysical and photochemical properties. It is used in high-tech fields, including semiconductor devices, photovoltaic and solar cells, electrophotography, rectifiers, and photosensitizers for LB film photodynamic therapy. Photosensitizers have great development prospects. [0003] The diversity and structural "tailorability" of phthalocyanine compounds provide the possibility for people to rationally design the required phthalocyanine compounds. Linking phthalocyanine with other functional groups to form new functional materials with complementary functions is one of the important development directions of phthalocyanine compounds. However, m...
