Peptide tertiary amides (PTAs) are a superfamily of peptidomimetics that include but are not limited to peptides, peptoids and N-methylated peptides. Here we describe a synthetic method which combines both split-and-pool and sub-monomer strategies to synthesize a one-bead one-compound library of PTAs.

Chemical Modification of the Tryptophan Residue in a Recombinant Ca2+-ATPase N-domain for Studying Tryptophan-ANS FRET

ANS binds to the Ca2+-ATPase recombinant N-domain. Fluorescence spectra display a FRET-like pattern upon excitation at a wavelength of 295 nm. NBS-mediated chemical modification of Trp quenches the fluorescence of the N-domain, which leads to the absence of energy transfer (FRET) between the Trp residue and ANS.

The protocol presented here shows the synthesis of a strong adhesive hydrogel gelatin o-nitrosobenzaldehyde (gelatin-NB). Gelatin-NB has rapid and efficient tissue adhesion ability, which can form a strong physical barrier to protect wound surfaces, so it is expected to be applied to the field of injury repair biotechnology.
FAQs
The amide carbonyl gives DMF a strong dipole, creating pronounced charge separation within the molecule. This polarity helps DMF interact with dissolved species and supports its role as a medium for reactions that involve nucleophiles or charged intermediates. Consequently, the carbonyl group is central to how the solvent accommodates reactive components during substitution, coupling, and condensation processes.
Because DMF lacks an acidic hydrogen, it does not readily donate protons to dissolved reactants. This feature allows the solvent to solvate cations while limiting proton-transfer effects that could interfere with nucleophiles or charged intermediates. Its non-proton-donating behavior therefore helps maintain reaction conditions suited to transformations involving these reactive species.
DMF’s polarity influences how effectively reaction components, including charged species, remain accommodated in the reaction medium. By supporting cation solvation and interactions with polar reactants, it can provide conditions favorable to reactions involving nucleophiles and charged intermediates. The solvent’s behavior should therefore be considered alongside the reaction’s chemical requirements rather than treated as incidental.
Selection should account for DMF’s polarity, chemical reactivity, and volatility. Polarity determines its ability to dissolve and accommodate reaction components, while chemical reactivity means the solvent must be considered in the overall reaction environment. Volatility affects handling and processing. Evaluating these properties together helps researchers decide whether DMF suits a particular reaction or application.
DMF can serve as the reaction medium for substitution, coupling, and condensation reactions. Its polar environment supports systems containing nucleophiles and charged intermediates, while its ability to dissolve varied compounds helps bring reaction components into a usable solution. Researchers select it when these solvent characteristics align with the chemical requirements of the transformation.
The broad dissolving capacity of DMF extends beyond small-molecule reactions to polymer-related applications. It can dissolve many polymeric compounds, making it useful as a solvent in polymer processing and coatings. In these settings, its role is to provide a workable medium for polymer-containing formulations, supporting preparation and application of materials that require polymer dissolution.
DMF is used for analytical sample preparation because it can dissolve a wide range of organic, inorganic, and polymeric compounds, helping researchers prepare samples in a suitable solvent medium. Handling decisions should also consider its volatility and chemical reactivity. These properties influence how the solvent is selected, processed, and managed during laboratory work.
