摘要: 本文首次报道半乳糖酞菁近红外荧光探针在肿瘤成像方面的应用。以酞菁为荧光发射基团,其在近红外区域有较高的量子产量和光学稳定性,可以解决探针的近红外光学特性;通过半乳糖对酞菁的修饰能够改善探针的溶解性和生物相容性,而且利用半乳糖的肿瘤靶向功能可以提高探针肿瘤主动靶向成像效果。结果表明它对恶性肿瘤具有高特异性结合和高灵敏度的分子探针体系,提高近红外光学分子成像效果。

Abstract: Abstract Phthalocyanine conjugation with galactose was synthesized as Near-infrared fluorescent probes. In vivo fluorescence imaging effect and organ distribution of probe was conducted with nude mice bearing liver cancer as model , result shows that galactose modified phthalocyanine have obvious near-infrared imaging effect in vivo and a certain tumor targeting ability. So the near infrared optical probe can be potentially applied in the diagnosis of cancer in future.

Key words: Near infrared fluorescence probe, Galactose, Phthalocyanines, Tumor imaging
