Beschreibung
Fmoc-lys(IVDDE)-OH is a kind of FMOC (9H-fluoren-9-ylmethoxycarbon) and N-IVDDE (1-(4,4-Dimethyl-2,6-dioxo-cyclohexylidene)-3-methyl-butyl) double protected amino acid (lysine). It is important during peptide manufacturing. It is mainly used for the production of peptides which required to be modified on the Lysine side chain, including peptides labeled peptides, PEGylated peptides or peptides cyclized through the Lys side chain. It can also be used for the manufacturing of anionic cell penetrating peptide which is useful for intracellular delivery of therapeutic agents such as proteins and nucleic acids. The IVDDE group can be conveniently removed thorough hydrazine in the presence of acid labile groups.
Chemische Eigenschaften
White to pale yellow powder
Verwenden
ivDde = 1-(4,4-Dimethyl-2,6-dioxo-cyclohexylidene)-3-methyl-butyl The ivDde protective group possesses higher orthogonality regarding Boc and Fmoc in comparison to Dde. Fmoc-Lys(Ddiv)-OH is orthogonally protected lysine. The Ddiv protection is stable to piperidine.
Verwenden
Fmoc-Lys(ivDde)-OH is especially useful for preparing peptides selectively modified on the Lys sidechain, such as peptides labeled peptides, PEGylated peptides or peptides cyclized through the Lys sidechain. The ivDde protective group possesses higher orthogonality regarding Boc and Fmoc in comparison to Dde. The ivDde group can be selectively removed with hydrazine in the presence of acid labile groups such as t-butyl and trityl based protecting groups.
Advantages
Fmoc-Lys(ivDde)-OH could be used to synthesize hetero-branched peptidesto avoid homodimer generation and construct heterodimers with a high ratio. This agent was used to generate Cellpenetrating peptides (CPP) and candidate peptides in one molecule[1].
