Amide bond formation is one of the most common fundamental reactions in organic synthesis, medicinal chemistry, and peptide chemistry. For a long time, when evaluating coupling reagents, the first concerns were usually whether the reaction was fast enough, whether the yield was high enough, and ...
tert-Butyl esters are among the most commonly used protecting groups for carboxylic acids. Their long-standing importance mainly rests on two features: first, they show good stability toward a variety of nucleophiles and reducing conditions; second, they can be removed relatively conveniently ...
Amide bond formation is one of the most common fundamental transformations in the synthesis of drug molecules, natural products, and functional molecules. In efforts to improve amidation reactions, researchers are concerned not only with whether a bond can be formed, but also with whether the ...
Peptides have become an important class of molecules in modern medicinal chemistry and chemical biology. Compared with traditional small molecules, peptides often offer higher target selectivity and stronger molecular recognition capability, while still retaining good structural tunability. As a ...
Condensation reactions between carboxylic acids and alcohols, and between carboxylic acids and amines, are among the most common fundamental transformations in organic synthesis, medicinal chemistry, and peptide chemistry. In the development of such reactions, the central question is no longer ...
Peptide synthesis is not a new problem. Since Merrifield established solid-phase peptide synthesis, resin supports, protecting-group strategies, coupling reagents, and heating methods have continued to evolve, with the same fundamental goals: improving chain-extension efficiency, reducing side ...
The core of glycoprotein structural characterization does not lie in confirming a single chemical entity, but in resolving a multilayered information system jointly defined by the protein backbone, glycosylation sites, site occupancy, glycan composition, branching patterns, terminal ...
Glucose metabolism and lipid metabolism together constitute the core network that sustains systemic energy homeostasis, biosynthesis, and signaling responses. Excess glucose can drive lipid production, whereas lipid intermediates can in turn interfere with insulin sensitivity, inflammatory ...
Intracellular electron transfer is not confined to the mitochondrial respiratory chain, but rather spans a continuous network involving glycolysis, the tricarboxylic acid cycle, fatty acid oxidation, amino acid catabolism, oxidative folding in the endoplasmic reticulum, oxidative metabolism in ...
