Felypressin acetate (PLV-2) is an agonist of vasopressin 1 and acts on all arginine vasopressin receptors 1AS. Felypressin acetate can be used in dental procedures.

Amylin (1-37) (human) (hIAPP (1-37)), a peptide hormone located in pancreatic beta-cell secretory granules, is characterized by an amidated C-terminus and a disulfide bond between cysteine residues 2 and 7 [1].

CHRG01, a biologically active peptide, originates from the C-terminal amino acids 54 to 67 of human β-defensin 3 (hBD-3), with a modified structure wherein all cysteine (Cys) residues are replaced by serine (Ser) to eliminate disulfide bond linkages. Like its parent compound hBD-3, CHRG01 exhibits antimicrobial properties that are dependent on electrostatic interactions.

Thrombospondin-1 (TSP-1)-derived CD36 binding motif is a bioactive peptide cyclized by a disulfide bond, critical for TSP-1-CD36 interaction. Involved in cancer metastasis, tumor adhesion, and angiogenesis, this matrix-bound glycoprotein-origin peptide competitively inhibits platelet aggregation and tumor metastasis.

Thioredoxin reductase peptide, corresponding to residues 53-67 in thioredoxin reductase (TrxR), is used in thioredoxin reductase research. Mammalian thioredoxin reductase (TR) catalyzes the reduction of the redox-active disulfide bond of thioredoxin (Trx) and is structurally and mechanistically similar to glutathione reductase, except for a C-terminal 16-amino acid extension containing a rare vicinal selenylsulfide bond.

APY-d3 is an EphA4-LBD antagonist peptide with a Kd value of 138 nM. It is constrained in a biologically active β-hairpin conformation through a disulfide bond linking its ends. APY-d3 is applicable for research in cancers such as gastric and pancreatic cancer, as well as in neurodegenerative diseases like amyotrophic lateral sclerosis and Alzheimer's disease.
