Polypeptide

Polypeptides are vital biomolecules with broad applications in biology and industry. It is composed of amino acids linked by polypeptide bonds. These polypeptide chains form the backbone of most proteins and are key to cellular functions, enzyme regulation, and structural support. Their efficiency makes them valuable in biotechnology, medicine, and manufacturing.

Bivalirudin

(128270-60-0)
Bivalirudin (Angiomax or Angiox, manufactured by The Medicines Company) is a specific and reversible direct thrombin inhibitor (DTI).Chemically, it is a synthetic congener of the naturally occurring drug hirudin (found in the saliva of the medicinal leech Hirudo medicinalis).Bivalirudin is a DTI that overcomes many limitations seen with indirect thrombin inhibitors, such as heparin. Bivalirudin is a short, synthetic peptide that is potent, highly specific, and a reversible inhibitor of thrombin.

Polypeptide is a compound formed by connecting α-amino acids with peptide bonds, and is an intermediate product of protein hydrolysis. Compounds usually formed by the dehydration and condensation of 10 to 100 amino acid molecules are called peptides. There are two types of peptides: biologically active peptides and synthetic peptides.

Application of polypeptide

With recent advancements in biotechnology, polypeptides have found increasing use as therapeutic agents. They can serve in diagnostic, curative, and preventative applications and can be synthesized artificially to meet clinical demands.

Due to their unique properties, polypeptides combine the characteristics of both small molecule drugs and protein-based therapies, making them a highly researched class of molecules. Insulin, for example, was the first polypeptide drug introduced, and since then, over 80 polypeptide-based drugs have been commercialized. These include peptide vaccines, anti-cancer peptides, antiviral peptides, cardiovascular peptides, cytokine mimetic peptides, antimicrobial peptides, and diagnostic peptides.

One of the major advantages of polypeptide drugs is their reduced likelihood of inducing drug resistance. However, they also pose significant challenges, such as higher toxicity and lower stability compared to other drug types. The immunogenicity and instability of polypeptide drugs are often attributed to chemical reactions like deamidation, oxidation, hydrolysis, and the formation of incorrect structures.
