Cyclopeptide Development Platform

Cyclopeptide refers to a polypeptide chain with a cyclic ring structure. Our company has extensive expertise in therapeutic peptide development, particularly in cyclopeptide development, our platform has talented and experienced scientists who can provide professional cyclopeptide design solutions and services to ensure that we can quickly respond to the changing needs of your rare disease therapy research project.

Introduction to Cyclopeptides

Cyclopeptides generally refer to compounds formed by amino acid peptide bonds, containing alternating L and D amino acids. The final structure is stabilized by hydrogen bonds, which are arranged perpendicular to the ring. Cyclopeptides can be used for structural and biological function studies of polypeptides as well as enzyme function and kinetic studies. Cyclopeptides are diverse and have a variety of biological activities, including:

  • Anti-tumor
  • Anti-HIV
  • Antibacterial
  • Antimalarial
  • Hypnotic
  • Antihypertensive
  • Inhibit tyrosinase
  • Inhibit cyclooxygenase
  • Inhibit lipid peroxidase
  • Immunosuppressive
  • Inhibit platelet aggregation

Cyclopeptides for Rare Diseases

Cyclopeptides not only have diverse biological activities, but also have the advantages of stability and ease of synthesis, so they have wide applications in different fields such as the pharmaceutical industry, diagnosis, vaccine, and agricultural applications. Not only that, cyclopeptides also have broad application prospects in the field of rare disease research. There have been some cases of cyclopeptides being used in the therapeutics and research of rare diseases:

  • Istodax for T-Cell Lymphoma
  • Pasireotide for Cushing's Syndrome
  • Setmelanotide for MC4R Deficiency
