Metronidazole-substituted dendrimer silicon phthalocyanine: a novel photodynamic therapy photosensitizer
2018
As an excellent second-generation photosensitizer for photodynamic therapy (PDT), phthalocyanine (Pc) complex has strong absorption peak in the near-infrared region and strong tissue penetrating ability, which endowed them excellent properties for the detection of tumor tissue. In recent years, in order to further ehnaced the penetration depth of the photosensitizer to the tissue, a large number of functional groups have been synthesized . In this work, we designed and synthesized metronidazole-substituted dendrimer silicon phthalocyanine (MT-SiPc) with near-infrared region Q-band of UV absorption, excellent fluorescence properties and photochemical properties.
