The dipeptide Val-Trp is a potent, competitive dipeptide angiotensin I-converting enzyme inhibitor with a Ki of 0.3 µM. Dipeptide-2 is a component of various cosmetic formulations, e.g. for anti-wrinkle and anti-aging cosmetics.

H-Val-Trp-OH is a noncompetitive inhibitor of the enzyme tyrosinase, which plays a role in melanin production. It also has radical scavenging activities and can inhibit the activity of other enzymes such as glucose 6-phosphate dehydrogenase and acetylcholinesterase. The compound is stable in aqueous solution and can be used to study the effects of H-Val-Trp-OH on wheat germ cells. It is composed of an amino acid sequence that resembles tyrosine, with a carboxylate group attached to the hydroxyl group at position 3. H-Val-Trp-OH is most active against tyrosinase when it is in its activated form, but it can also act as an inhibitor when it is not activated. The compound inhibits the activity of tyrosinase by binding to its active site and blocking the binding or catalysis of substrate molecules. This inhibition occurs through competitive interactions with
