| Targets |
This compound does not possess a specific biological target; its primary function is as a reagent for bioconjugation and peptide synthesis. As a valine derivative, it is used to introduce valine residues into peptides or to conjugate peptides to other molecules. The Z group provides protection for the amino group, while the succinimidyl ester activates the carboxyl group for efficient coupling with amine-containing molecules (e.g., peptides, proteins). Amino acids and their derivatives have been commercially used as ergogenic supplements.

| ln Vitro |
Commercial ergot supplements have been made from amino acids and their derivatives. They affect the release of anabolic hormones, the availability of fuel for activity, the ability to think clearly under pressure, and the prevention of muscular damage brought on by exertion. They are regarded as advantageous synergistic food ingredients [1].
This compound is not a biological agent and does not exhibit direct in vitro biological activity in a pharmacological sense. Its value lies in its chemical utility as a bioconjugation reagent and protected amino acid building block. Amino acids and their derivatives have been commercially used as ergogenic supplements. Any biological activity would reside in the final conjugated products, not in this reagent itself. |
| ln Vivo |
Z-Val-Osu is not administered in vivo as a therapeutic agent. It is a research chemical utilized as a reagent in bioconjugation reactions and peptide synthesis. The final conjugated products, not this reagent, would be the subject of in vivo pharmacological testing. The compound is for research use only and is not intended for human or veterinary therapeutic applications.
|
| Enzyme Assay |
Non-cellular enzyme/receptor binding assays are not applicable to Z-Val-Osu as it is not biologically active. Its use is in bioconjugation chemistry and peptide synthesis. A typical protocol involves its use as an activated ester to couple valine to an amine-containing molecule (e.g., peptide, protein, or small molecule) under mild conditions. The succinimidyl ester reacts efficiently with primary amines to form stable amide bonds.
|
| Cell Assay |
This compound is not used in cell-based assays as a therapeutic agent. Its applications are in synthetic chemistry and bioconjugation. It should be stored at room temperature in a cool and dark place. Purity is typically ≥95%. The product is for research purposes only and is not intended for human or veterinary use.
|
| Animal Protocol |
In vivo animal experiments do not involve Z-Val-Osu as a test article. It is a chemical reagent used in the synthesis of bioconjugates or peptide-based drug candidates. If a researcher synthesizes a therapeutic conjugate using this reagent, that final product would be subjected to animal testing. The reagent itself is never administered to animals as a test compound.
|
| ADME/Pharmacokinetics |
Pharmacokinetic properties are not applicable to Z-Val-Osu as it is not a drug. It is a small molecule (MW 348.35 g/mol) with the formula C17H20N2O6. Its properties are relevant for chemical handling and storage rather than for systemic exposure studies. The compound is not designed to be bioavailable, as it is a reactive reagent intended for chemical conjugation.
|
| Toxicity/Toxicokinetics |
The toxicity of Z-Val-Osu is not extensively documented, as it is a research chemical not intended for human or veterinary use. As with all activated esters, standard laboratory safety precautions should be followed, including handling in a well-ventilated area with appropriate personal protective equipment. It should be stored in a cool, dark place and protected from moisture.

|
| Additional Infomation |
Z-Val-Osu (N-Cbz-L-valine succinimidyl ester) is a derivative of the amino acid valine where the amino group is protected by a Z group and the carboxyl group is activated as a succinimidyl ester. It is commonly used as a reagent in bioconjugation reactions. The succinimidyl ester activates the carboxyl group for efficient coupling with amine-containing molecules. It is not a pharmaceutical.
