Modular peptides displaying both quantum dot bioconjugation motifs and specific subcellular targeting domains were constructed using a chemoselective aniline-catalyzed hydrazone coupling chemistry. Peptides were ratiometrically assembled onto quantum dots to facilitate their specific delivery to either the plasma membrane, endosomes, the cytosol or the mitochondria of target cells.
The direct synthesis of dithiophenol maleimide functional polymers by living radical polymerisation is described without the need for protecting group chemistry. The synthesised polymers have been successfully employed as disulfide bridging agents for salmon calcitonin when used in equimolar quantities, negating the requirement for complex purification strategies, traditionally associated with ...
An efficient aqueous Wittig reaction was enabled on protein bioconjugation for the first time. By investigating the reaction on small molecules, peptides, and proteins, a site-specific reaction targeting "aldehyde tag" was presented. A variety of functional groups could be introduced into the protein of interest.
Biocompatible and robust gold nanoparticles (AuNPs) were prepared via a simple synthetic strategy employing dextran as a reducing agent and surface coating material. Cross-linking and amination of the surface-coated dextran significantly improved the colloidal stability of AuNPs and rendered the nanoparticles more amenable to bioconjugation.
Tuning the properties of maleimide reagents holds significant promise in expanding the toolbox of available methods for bioconjugation. Herein we describe aryloxymaleimides which represent 'next generation maleimides' of attenuated reactivity, and demonstrate their ability to enable new methods for protein modification at disulfide bonds.
