We report the synthesis of bioconjugated zinc porphyrin dimers 1a-e designed as photosensitizers for one-photon and two-photon excited photodynamic therapy. These macrocycles are substituted with carbohydrate units (glucose, mannose, lactose) in order to target tumor cells over-expressing lectin membrane receptors. Polarity, singlet oxygen production and in vitro photocytotoxicity are studied to determine their photodynamic therapy potentiality.
我们报告了生物共轭锌卟啉二聚体 1a-e 的合成,这些二聚体被设计为用于单光子和双光子激发光动力疗法的光敏剂。这些大环化合物被糖单位(葡萄糖、甘露糖、乳糖)取代,以靶向过度表达凝集素膜受体的肿瘤细胞。研究了它们的极性、单线态氧的产生和体外光细胞毒性,以确定它们的光动力治疗潜力。
