labeling inside pathogenic Gram-negative bacterial cells via a ligand-free palladium-mediated cross-coupling reaction. Two rationally designed pyrrolysine analogues bearing an aliphatic alkyne or an iodophenyl handle were first encoded in different enteric bacteria, which offered two facial handles for palladium-mediated Sonogashira coupling reaction on proteins within these pathogens.

The present invention relates to novel insulin derivatives and their use in the treatment or prevention of medical conditions relating to diabetes. The insulin derivatives are glucose sensitive and display glucose-sensitive insulin receptor binding. The invention also relates to novel intermediates. Finally, the invention provides a pharmaceutical composition comprising the insulin derivatives of the invention and the use of such a composition in the treatment or prevention of medical conditions relating to diabetes.
Thiol–yne radical reaction mediated site-specific protein labeling via genetic incorporation of an alkynyl-l-lysine analogue
Three alkyne-containing pyrrolysine derivatives were synthesized and genetically encoded into proteins by a mutant PylRSâtRNA pair with high efficiencies. With these alkyne handles, site-specific dual labeling of proteins can be achieved via a bioorthogonal thiolâyne ligation reaction.
