Develop high-quality peptidomimetics with Creative Proteomics’ β-Amino Acids Analysis solutions

SHIRLEY, NY, UNITED STATES - Feb 1, 2020 - β-amino acid refers to an amino acid in which an amino group is bonded to a carbon atom at the β position. The only common naturally occurring β-amino acid is β-alanine. Although β-alanine is often used as a component of biologically active macromolecules, β-peptides generally do not occur in nature. For this reason, β-peptide antibiotics are being used to solve the problem of antibiotic resistance.

β-Amino acid also offers promising opportunities to develop biologically active peptidomimetics, either employed alone or in conjunction with natural α-amino acids. Since it has great potential for unique conformational preferences that deviate considerably from α-peptide geometries, β-amino acid can expand the possible chemistries and physical properties available to polyamide foldamers.

β-amino acids are subdivided into β2-, β3- and β2, 3-amino acids depending on the position of the side chain at the 3-aminopropionic acid core. In addition, cyclic amino acids have the amino group integrated in a ring, as is the case in β-proline.

Many peptide drugs currently on the market are made by amide bond condensation using conventional natural amino acids. Natural amino acids are also called α-amino acids. This polypeptide can form a stable secondary structure through α-helix and β-sheet, which can play a good role in regulating some enzymes in the human body. However, there are many proteases in the human body. Proteases often hydrolyze peptides, resulting in the metabolism of peptide drugs in the human body, shortening the half-life, increasing the cost of administration and the difficulty of administration.

After a long period of research by scientists, comparing peptides synthesized using β-amino acids and α-amino acids, it was found that peptides synthesized using β-amino acids (β-peptide) also have good biological activity, good hydrolysis of proteases tolerability, and longer half-life. In the future, the use of β amino acids as the backbone of peptide drugs will become a research hotspot.
