To illustrate the impact of suboptimal coupling yields for a given synthesis, consider the case where each coupling step were to have at least 99% yield: this would result in a 77% overall crude yield for a 26-amino acid peptide (assuming 100% yield in each deprotection); if each coupling were 95% efficient, the overall yield would be 25%.
N,N ′-Diisopropylcarbodiimide is a carbodiimide used in peptide synthesis. [1] [2] As a liquid, it is easier to handle than the commonly used N,N ′-dicyclohexylcarbodiimide, a waxy solid. In addition, N,N ′-diisopropylurea, its byproduct in many chemical reactions, is soluble in most organic solvents, a property that facilitates work-up.
It is incompatible with traditional solid-phase peptide synthesis. DCC is a potent allergen, and repeated contact with skin increases the probability of sensitization to the compound. Clinical reports of individuals who cannot enter rooms where peptide coupling agents are used have been reported.
N,N′-Dicyclohexylcarbodiimide (DCC or DCCD) [1] is an organic compound with the chemical formula (C 6 H 11 N) 2 C. It is a waxy white solid with a sweet odor. Its primary use is to couple amino acids during artificial peptide synthesis.
Common uses for this carbodiimide include peptide synthesis, protein crosslinking to nucleic acids, but also in the preparation of immunoconjugates. EDC is often used in combination with N-hydroxysuccinimide (NHS) for the immobilisation of large biomolecules. Recent work has also used EDC to assess the structure state of uracil nucleobases in RNA.
DEPBT (3-(diethoxyphosphoryloxy)-1,2,3-benzotriazin-4(3H)-one) is a peptide coupling reagent used in peptide synthesis.It shows remarkable resistance to racemization. [1]Fmoc-Dab(Mtt)-OH, a commercially available amino acid building block for solid-phase peptide synthesis (SPPS), was proven to undergo rapid lactamization, instead of reacting with the N-terminal end of the peptide.
