for fluorescentlabeling of biomolecules is presented by examples on model frameworks representing major biopolymer building blocks. The versatility of these dyes is presented in cell labeling experiments as well as by labeling the azide modified surface glycans of CHO-cells either by copper catalyzed or copper-free clickreaction. These dyes are expected to have a large variety of applications in (bio)orthogonal
In search of safe and effective anti-Alzheimer disease agents a series of gallocyanine dyes have been synthesized and evaluated for their ability to inhibit LRPs/DKK1 interactions. Modulation of the interactions between LRPS and DKK1, regulate Wnt signaling pathway and affect Tau phosphorylation. The current efforts resulted in the identification of potent DKK1 inhibitors which are able to inhibit

Maleinimides are widely used to label proteins and to derivatize thiols. The so-called click reaction was shown to allow the efficient introduction of the maleinimido group into azido-modified fluorophores (benzoxazines) by reacting them with an alkyne-modified maleinimide to yield new thiol-reactive fluorescent labels 5–7. The reaction proceeds under mild experimental conditions and provides a new
