Piperazine-modified phthalocyanine complex and preparation method thereof
InactiveCN103772397AEnhance amphipathicMaintain high photodynamic activityOrganic chemistryEnergy modified materialsBiocompatibility TestingSinglet oxygen
The invention discloses a piperazine-modified phthalocyanine complex as well as a preparation method and an application thereof. Piperazine molecules are introduced into the macrocyclic periphery of a metal phthalocyanine so as to enhance the amphipathy, the biocompatibility and the targeting of the phthalocyanine. A piperazine group contains two N atoms, so that after the synthesized phthalocyanine complex enters a tissue, if the tissue is normal, the single excitation state of the phthalocyanine can be quenched by lone pair electrons on the N atoms of the piperazine group under a light irradiation condition. Thus, the generation of singlet oxygen is avoided. If the tumor tissue is in a weak acid state, the N atoms are protonated, so that the single excitation state of the phthalocyanine cannot be quenched. Therefore, the singlet oxygen is generated so as to kill tumor cells. Based on the theory, the selectivity of the photodynamic therapy of the phthalocyanine is improved due to the introduction of the piperazine group, so that the damage of the phthalocyanine to the normal tissue is reduced. The piperazine-modified phthalocyanine complex has a single structure and does not contain isomers, and is easy to purify and low in cost, thereby being favorable for industrial production.
