Ex post glycoconjugation of phthalocyanines.

For the first time, fully fledged phthalocyanines (Pcs) were ex post glycoconjugated, that is, via 1,3-dipolar cycloaddition reaction. This divergent approach gains rapid access to a broad range of highly diverse Pcs bearing chemically sensitive substituents. This will be a breakthrough in generating structure-activity relationships (SAR) for the development of novel bioactive molecules.
