Chemoselective sequential "click" ligation using unsymmetrical bisazides.
Unsymmetrical bisazides containing chelating and nonchelating azido groups undergo chemoselective three-component copper(I)-catalyzed azide-alkyne conjugation reactions with two different alkyne molecules. In conjunction with the reactivity gap between aromatic and aliphatic alkynes, a bistriazole molecule can be generated with excellent regioselectivity by mixing two alkynes and a bisazide in ...
متن کاملRecent Carbohydrate-Based Chemoselective Ligation Applications
Abstract: Chemoselective ligation reactions are highly efficient and specific covalent bond forming reactions capable of proceeding within a physiological environment. Chemoselective ligations offer exquisite specificity, similar to enzymatic reactions, but with the significant advantage of accessing a much broader range of coupling partners. Thus, even among a multitude of reactive functional ...
متن کاملTraceless purification and desulfurization of tau protein ligation products.
We present a novel strategy for the traceless purification and synthetic modification of peptides and proteins obtained by native chemical ligation. The strategy involves immobilization of a photocleavable semisynthetic biotin-protein conjugate on streptavidin-coated agarose beads, which eliminates the need for tedious rebuffering steps and allows the rapid removal of excess peptides and additi...
متن کاملA hydrazide-anchored dendron scaffold for chemoselective ligation strategies.
Chemoselective ligation, including "click" chemistry, has found wide utility in general synthetic strategies and the specific modification of polymers and biomolecules. This has resulted in a number of applications of such approaches, particularly in the biomedical area, including diagnostic imaging and drug delivery. However, tools to chemoselectively decorate target molecules with multiple co...
متن کاملGeneral Chemoselective and Redox-Responsive Ligation and Release Strategy
We report a switchable redox click and cleave reaction strategy for conjugating and releasing a range of molecules on demand. This chemoselective redox-responsive ligation (CRRL) and release strategy is based on a redox switchable oxime linkage that is controlled by mild chemical or electrochemical redox signals and can be performed at physiological conditions without the use of a catalyst. Bot...
