Bestatin is a competitive and specific inhibitor of leucine aminopeptidase, aminopeptidase B, and triamino peptidase.

H-Val-Tyr-OH is an endogenous metabolite.

Pidotimod is a synthetic dipeptide with immunomodulatory properties.It can modulate the immune system to induce an immune response against bacterial or viral pathogens.

L-carnosine is an antioxidant naturally found in skeletal muscle, brain tissue, and the heart, it can scavenge oxygen free radicals and transition metal ions, block protein-protein and protein-DNA cross-links induced by hypochlorite anions and toxic aldehydes, inhibit nonenzymatic protein glycation induced by aldose and ketose reducing sugars and inhibit the formation of toxic advanced glycation end products (AGE).

Fmoc-Val-Cit-PAB-OH is a linker for ADC through cleaveage by catepsin B only present in lysosome at Val-Cit site, thus making ACD payload be released only in the cell.

Val-Cit-PAB-OH is a linker for ADC through cleaveage by catepsin B only present in lysosome at Val-Cit site, thus making ACD payload be released only in the cell.

Glycylglycine is the dipeptide of glycine, it can be used as a buffer for biological systems, as well as in the synthesis of more complex peptides.

H-Gly-Pro-OH is a dipeptide composed of glycine and proline, and is an end product of collagen metabolism that is further cleaved by prolidase. The resulting proline molecules are recycled into collagen or other proteins.

Glycyl-L-valine is a dipeptide composed of glycine and valine. It is an incomplete breakdown product of protein digestion or protein catabolism.

Glycyl-l-leucine is a dipeptide that appears to be a common substrate for glycyl-leucine dipeptidase.

Aspartame is an artificial non-saccharide sweetener used as a sugar substitute in some foods and beverages. It is a methyl ester of the aspartic acid/phenylalanine dipeptide.
