Cholecystokinin octapeptide (CCK-8) is a peptide hormone that belongs to the enkephalinase inhibitor family. It is a desulfated molecule with an amidated C-terminus and has been shown to inhibit the activity of aminopeptidases, which are enzymes that break down peptides. Cholecystokinin octapeptide (CCK-8) is found in the brain where it acts as a neurotransmitter and has been shown to have anti-inflammatory effects. This molecule has also been found to be effective in the treatment of cerebral disorders such as Parkinson's disease, Alzheimer's disease, and Huntington's disease by inhibiting glutamate release from nerve cells.

Secretin acetate salt H-His-Ser-Asp-Gly-Thr-Phe-Thr-Ser-Glu-Leu-Ser-Arg-Leu-Arg-Asp-Ser-Ala is a peptide that is secreted by the pancreas in response to the ingestion of food. Secretin stimulates the release of water and bicarbonate from the pancreas, as well as stimulating the gallbladder to contract, which results in increased flow of bile. Secretin also inhibits gastric acid secretion, slows intestinal motility, and stimulates pancreatic enzyme secretion. The amino acid sequence of this peptide is identical to that of leuprolide acetate (Lupron) and goserelin acetate (Zoladex), which are synthetic analogs with similar biological activity. This peptide can be synthesized on a solid phase or in solution phase. Solid phase synthesis involves attaching amino acids

4-Methoxyphenyl boronic acid is a molecule with a hydroxyl group and a boronic acid. It is synthesized by reacting biphenyl with trifluoroacetic acid in the presence of sodium carbonate and palladium-catalyzed coupling. 4-Methoxyphenyl boronic acid has shown to bind to the receptor for fatty acids, which may be due to its structural similarity to p-hydroxybenzoic acid. The protonated form of this molecule has been shown to react with an electrophilic carbon atom and an electron-deficient alkyl or vinyl halide, resulting in ring formation. This reaction is known as the Suzuki coupling reaction.

Suc-Ala-Lys-Pro-Phe-pNA is a casein that has been modified to contain additional lysine residues. This modification increases the protein’s stability, making it more resistant to hydrolysis by phosphatases. Suc-Ala-Lys-Pro-Phe-pNA also contains a peptide sequence that is homologous to a part of the endoplasmic reticulum chaperone FK506 binding protein (FKBP). The peptide sequence in this casein acts as an artificial chaperone and can be used in cell culture experiments to stabilize newly synthesized proteins.

Myeloblastin (142-150) (human, mouse) trifluoroacetate salt HVal-Leu-Gln-Glu-Leu-Asn-Val-Thr-Val-OH trifluoroacetate salt is an antigen that belongs to the class of serine proteinases. It is a soluble recombinant human proteinase that has been shown to have a tumor cell lysis activity in vitro and in vivo. Myeloblastin (142-150) (human, mouse) trifluoroacetate salt HVal-Leu-Gln-Glu-Leu-Asn-Val-Thr Val is also a leukocyte antigen and can be used for the development of cancer vaccines.

H-D-Leu-D-Leu-OH is a type of molecule that can be found in the human body. It is an amino acid with specificities and transport mechanisms that are not yet well understood. This compound is resistant to aminopeptidase activity and has been shown to have a ph optimum in the intestinal tract. Acetylation of this molecule may also have an effect on its transport rate, as it has been shown to affect the transport rate of D-tryptophan and D-alanine.

N-alpha-Fmoc-N-delta-Boc-D-ornithine (NFDO) is an antibiotic that belongs to the group of macrocyclic, cyclic antibiotics. This drug has antibacterial activity against gram-negative pathogens and is most effective against E. coli. NFDO is synthesized by a solid phase synthesis that occurs in two stages: first, FMOC protected amino acids are coupled to the resin and then deprotection is carried out with piperidine in DMF at room temperature. The final product is obtained by cleavage of the peptide from the resin with trifluoroacetic acid and purification by HPLC.
