A versatile derivative for the introduction of a highly reactive aldehyde functionality into a peptide side chain. This protected building block is compatible with Fmoc/tBu SPPS conditions and the cyclic actelal will cleave upon standard cleavage conditions with TFA/water and liberating the side chain aldehyde group. Allysine is produced naturally by the
action of lysyl oxidase on protein residues. Cross-links formed between the reaction of allysine and lysine and hydroxylysine residues are responsible for giving collagen fibrils their tensile strength.
Due to the reactivity of the aldehyde function, certain reactions will occur and precautions have to be undertaken:
The use of thiol-based scavengers should be avoided as their use can lead to thioacetal formation. Cysteines, homocysteines or other thiol bearing groups can form bicyclic analogous. N-Terminal allysine will react with amines, such as pyridines and form e.g. 1-piperidiene-6-carboxyl peptides. In case the N-terminal residue attached to the allysine is free, the product is likely be the corresponding peptide containing either 2-hydroxypiperidine carboxylic or 2-piperidien-6-carboxylic acid.
