“Racemization” in peptide synthesis is often discussed as if it were mainly a question of whether one coupling reagent is better than another. From the standpoint of reaction chemistry, however, what deserves greater caution is the period after the carboxylic acid has been activated. In many ...
The full name of Boc-Oxyma is ethyl 2-(tert-butoxycarbonyloxyimino)-2-cyanoacetate, i.e., 2-(tert-butoxycarbonyloxyimino)-2-cyanoacetic acid ethyl ester. Based on the currently available published literature, Boc-Oxyma has developed three main lines of application together with one bridging use ...
Glucuronidation is an important phase II metabolic pathway in the clearance of drugs and endogenous metabolites, but its biological consequences do not necessarily terminate once the host conjugation reaction is completed.
In amide and peptide synthesis, whether a bond can be formed is certainly important. However, for amino acids, peptide fragments, and chiral carboxylic acid substrates containing an α-stereogenic center, another issue often plays an equally decisive role in determining the quality of the ...
HATU [O-(7-azabenzotriazol-1-yl)-N,N,N′,N′-tetramethyluronium hexafluorophosphate] has long been used as a high-performance coupling reagent, but the real reason it merits separate discussion is not simply that reactions proceed faster. In couplings between ordinary carboxylic acids and ...
TBTU [O-(benzotriazol-1-yl)-N,N,N′,N′-tetramethyluronium tetrafluoroborate] has long been one of the most commonly used coupling reagents for carboxylic acid activation and amide bond formation, and has been widely employed in both solution-phase amidation and solid-phase peptide synthesis ...
Voltage-gated potassium channels are an important ion channel family that regulates membrane repolarization, firing frequency, and excitability threshold.
Tissue dissociation for single-cell preparation is a critical methodological step linking the original sample state to downstream flow sorting, single-cell transcriptomics, spatial validation, and functional assays.
Sulfonyl groups are among the most common classes of groups used in amine protection chemistry. Their role is not limited to temporarily masking an amino group; they also significantly alter the reactivity of the nitrogen atom. As a result, they are often used in selective alkylation, Mitsunobu ...
