It appears as a white powder and has a purity of ≥98%. The compound serves as an amine-reactive coupling reagent and protein cross-linking agent for research applications. It is widely utilized in research focused on peptide synthesis, enabling researchers to create complex biomolecules efficiently. The compound is also classified as a Biochemical Assay Reagent. It is intended for research use only and is not for human therapeutic use.
Biological Activity I Assay Protocols (From Reference)
Targets
6-(N-Boc)caproic acid NHS functions as a protein cross-linking agent and amine-reactive coupling reagent. Its primary targets are amine groups on proteins and peptides. The NHS ester moiety reacts with primary amines (such as the epsilon-amino group of lysine residues) to form stable amide bonds. This reaction allows the compound to cross-link proteins or to conjugate biomolecules. The Boc (tert-butoxycarbonyl) protecting group provides temporary protection of the amine functionality, which can be removed under acidic conditions for further derivatization. The compound's biochemical pathway involves the formation of covalent amide bonds with amine-containing molecules.
ln Vitro
In vitro studies of 6-(N-Boc)caproic acid NHS have focused on its role as a protein cross-linking agent and coupling reagent. The compound's reactivity with primary amines has been characterized in various in vitro systems. It is used in peptide synthesis to create complex biomolecules efficiently. The compound's purity of ≥98% supports its use in research applications. As an amine-reactive NHS ester, its reactivity and stability have been characterized in biochemical assays. These in vitro studies provide foundational data for understanding the compound's utility in bioconjugation and peptide synthesis applications.
ln Vivo
In vivo studies of 6-(N-Boc)caproic acid NHS are not applicable, as the compound is a research reagent used for in vitro bioconjugation rather than a therapeutic agent. The compound is used to modify proteins and peptides in vitro for research purposes. Its applications in peptide synthesis suggest it may be used in the production of peptides that are subsequently evaluated in vivo. However, the compound itself is not administered to living organisms. Its Boc protecting group is typically removed under acidic conditions before use, making the compound a temporary modification reagent. The compound is not intended for human therapeutic use.
Enzyme Assay
In vitro enzyme and receptor binding assays are not typically performed for 6-(N-Boc)caproic acid NHS, as the compound is a chemical coupling reagent rather than a biological agent. Its reactivity is assessed using analytical chemistry methods such as thin-layer chromatography (TLC) to confirm purity. The compound's ability to form amide bonds with amines is evaluated using standard bioconjugation protocols. High-performance liquid chromatography or mass spectrometry is used to confirm conjugation efficiency. All assays are performed with appropriate controls and standardized protocols to ensure reproducibility of results.
Cell Assay
In vitro cell-based assays are not applicable for 6-(N-Boc)caproic acid NHS, as the compound is a chemical reagent used for bioconjugation rather than a biological agent. The compound is used to modify proteins and peptides outside of cells. Its reactivity with primary amines is exploited in biochemical applications such as protein labeling and cross-linking. The compound is not intended for cell-based studies as a direct pharmacological agent. Cell-based assays may be used to evaluate the biological activity of peptides or proteins that have been modified using this compound, but the compound itself is not tested in cell-based systems.
Animal Protocol
In vivo animal experiments are not applicable for 6-(N-Boc)caproic acid NHS, as the compound is a research reagent used for in vitro bioconjugation rather than a therapeutic agent. The compound is not administered to animals for pharmacological evaluation. Its applications in peptide synthesis suggest it may be used in the production of peptides that are subsequently evaluated in animal models. However, the compound itself is not intended for in vivo use. All procedures involving the compound are conducted in laboratory settings for research purposes only.
ADME/Pharmacokinetics
The pharmacokinetic properties of 6-(N-Boc)caproic acid NHS are not applicable, as the compound is a research reagent used for in vitro bioconjugation rather than a therapeutic agent. It has a molecular weight of 328.36 and the molecular formula C15H24N2O6. The compound appears as a white powder and is stored as a powder at -20°C for up to 3 years. In solvent, it can be stored at -80°C for 6 months or at -20°C for 1 month. The compound is transported at room temperature in continental US. Its stability and reactivity are characterized in research applications.
Toxicity/Toxicokinetics
The toxicity profile of 6-(N-Boc)caproic acid NHS has been evaluated in the context of its use as a research chemical. The compound is classified as a research chemical intended for laboratory use only. As an NHS ester, it is reactive and should be handled with care. Proper handling procedures including use of personal protective equipment are recommended. The compound is not approved for human therapeutic use. Long-term toxicity studies would be needed to fully establish its safety profile. The compound's reactivity with amines suggests it could potentially modify biological molecules if exposure occurs, emphasizing the need for proper handling and safety precautions.
