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
Compounds like putrescine, spermidine, and spermine play important roles in a many biological functions. Many of them are excellent targets for oncology studies and other fields of medicinal chemistry.
Find in our new brochure Diamines & Polyamines our possibilities for custom synthesis and a set over 100 available derivatives.
Any amino acid can be functionalized on the N-terminus with oxalic acid and on the C-terminus with hydrazine, in order to form a so-called NXO building block. Through this double modification N and C terminus will be inverted, which provides interesting structural options for peptidomimetics.read more
