Synthesis of phthalocyanines with asymmetrical substitution on the periphery is often difficult due the problems in purification of the phthalocyanine mixtures obtained. Using a poly(ethylene glycol) (PEG)-based support with a Wang-type linker, we have developed the synthesis of monohydroxylated, oligoethylene glycol substituted phthalocyanines utilizing an amidine-base-promoted phthalonitrile tetramerization
由于所获得的酞菁混合物的纯化问题,在外围具有不对称取代的酞菁的合成通常是困难的。使用基于聚(乙二醇)(PEG)的支持物和 Wang 型接头,我们开发了利用脒碱促进的邻苯二甲腈四聚反应合成单羟基化、低聚乙二醇取代的酞菁。亲水性载体的使用允许在溶液中形成的对称酞菁产物通过洗涤容易且完全去除,同时留下“AB 3”产品上的支持。用 10% 三氟乙酸酸裂解得到纯的不对称取代的 Pc。这种方法被应用于几个金属 Pcs。此外,提供了避免在树脂上产生A 2 B 2产物的过早反应的方法。

we designed a solid-phase strategy for the efficient synthesis of peptide–phthalocyanine (Pc) conjugates with two types of highlyhydrophilic modifications to the Pc rings. The peptide conjugation clearly increased the photodynamic efficacy and selectivity of Pcs against cancer cells with different receptor expression levels. A highlyhydrophilic modification to the Pc rings can block non-specific interactions

Biological uses of photosensitizers in photodynamic therapy (PDT) often suffer from a lack of tumor selectivity; a strategy based on molecule-targeted cancer therapies could provide a promising solution.
Asymmetrically substituted metal-phthalocyanine compounds are disclosed. These compounds and other phthalocyanine-derivatives are used in bioimaging, bioanalysis, FRET and quenching techniques, photodynamic therapy, DNA analysis for cells, proteins, tissues and other biological entities, and other applications. Near-infrared fluorescence minimizes matrix effects typically seen in other methods of analyzing biochemical entities in cells, proteins, tissues and other biological entities.
