Surprising behavior of NXO-peptides.
It is a significant property of peptides that oxalo-retro azapeptides have the same donor and acceptor distances and properties for hydrogen bridge formation as a tripeptide fragment and therefore induce beta-sheet formation at this position.
Alkylating the Nitrogen of an amide bond results in peptoid structures, leading to conformational restrains, like N-methylation and allows backbone derivatisation. Applications already have been published with Cilengitide, Piscidin 1, and MC4 receptor agonist.read more
Positions next to Glycine are often reasons for side reactions, as aspartamide or diketopiperazine formation can occur. Dmb and Tmb can be used for temporary protection of the amide nitrogen of a peptide bond, in order to solubilize the peptide and increase yield and purity.read more
