Selective chemical reactions enacted within a cellular environment can be powerful tools for elucidating biological processes or engineering novel interactions. A chemical transformation that permits the selective formation of covalent adducts among richly functionalized biopolymers within a cellular context is presented. A ligation modeled after the Staudinger reaction forms an amide bond by coupling of an azide and a specifically engineered triarylphosphine. Both reactive partners are abiotic… 

Engineering Cell Surfaces by Covalent Grafting of Synthetic Polymers to Metabolically-Labeled Glycans

Using metabolic glycan labeling to install azido groups onto the cell surface, this approach may enable the attachment of payloads and modulation of cell function and fate, as well as providing a tool to interface synthetic polymers with biological systems.

Controlled Detachment of Chemically Glued Cells.

We demonstrate a chemically detachable cell-glue system based on linkers containing disulfide bonds as well as functional groups for metabolic glycoengineering and bioorthogonal click chemistry.

Chemical remodeling of cell-surface sialic acids through a palladium-triggered bioorthogonal elimination reaction.

Palladium nanoparticles were found to be a highly efficient and biocompatible depropargylation catalyst for the direct conversion of metabolically incorporated N-(propargyloxycarbonyl)neuramic acid (Neu5Proc) into Neu on cell-surface glycans by the use of a palladium-mediated bioorthogonal elimination reaction.

A Bioorthogonal Reaction of N-Oxide and Boron Reagents.

This report seeks to expand the functional repertoire of such transformations by introducing a new bond-cleaving reaction between N-oxide and boron reagents, and demonstrates that the metabolic diversity of nature enables the use of naturally occurring functional groups that display inherent biocompatibility alongside abiotic components for organism-specific applications.

From Mechanism to Mouse: A Tale of Two Bioorthogonal Reactions

Work in the laboratory led to the development of two bioorthogonal transformations that exploit the azide as a small, abiotic, and bioinert reaction partner: the Staudinger ligation and strain-promoted azide–alkyne cycloaddition.

Bioorthogonal Click Chemistry-Based Synthetic Cell Glue.

The results demonstrate the promising potential of chemically glued cell pairs for various applications ranging from delivering therapeutic cells to studying cell-cell interactions in vivo.

Azide: A Unique Dipole for Metal‐Free Bioorthogonal Ligations

The potential of azides to undergo metal‐free reactions with strained unsaturated systems has inspired the development of an increasing number of reactive probes, which are comprehensively summarized here.

An introduction to the chemical reactivity of the amino acid side chains is provided, with an emphasis on the selectivity that can be achieved using a particular reactive strategy.



Engineering chemical reactivity on cell surfaces through oligosaccharide biosynthesis.

The versatility of this technology was demonstrated by an example of selective drug delivery, where cells were decorated with biotin through selective conjugation to ketone groups, and selectively killed in the presence of a ricin A chain-avidin conjugate.

Metabolic Delivery of Ketone Groups to Sialic Acid Residues

A general strategy for engineering the display of chemically defined oligosaccharides on cell surfaces that combines the concepts of metabolic engineering and selective chemical reactivity is described.

These data are the first to suggest the feasibility of a strategy that improves the efficiency of gene transfer by using the biosynthetic machinery of the cell to engineer novel sugars on the cell surface.

Specific covalent labeling of recombinant protein molecules inside live cells.

This system provides a recipe for slightly modifying a target protein so that it can be singled out from the many other proteins inside live cells and fluorescently stained by small nonfluorescent dye molecules added from outside the cells.

Nicotinic receptor binding site probed with unnatural amino acid incorporation in intact cells.

Disaccharide uptake and priming in animal cells: inhibition of sialyl Lewis X by acetylated Gal beta 1-->4GlcNAc beta-O-naphthalenemethanol.

The general utility of using acetyl groups to create disaccharide primers was shown by the priming of oligosaccharides on peracetylated Gal beta 1-->4GlcNAc beta-O-naphthalenemethanol, which inhibited sialyl Lewis X expression on HL-60 cells.

The reaction between thiols and 8-azidoadenosine derivatives.

Thiols react at room temperature in dilute solution with 8-azidoadenosine and its nucleotides to give the corresponding 8-aminoadenosines derivatives to give dithiols, e.g. dithiothreitol.
