| Targets |
Fmoc-Lys(Dde)-OH does not have a specific biological target. Its primary utility is as a chemical building block in organic synthesis, particularly in Fmoc-based peptide synthesis. The compound serves as a protected lysine unit that can be incorporated into peptide chains while the Fmoc and Dde groups protect the α-amino and ε-amino groups, respectively, from unwanted reactions. Lysine is an essential amino acid involved in protein synthesis and post-translational modifications, but in its protected form, the compound is not designed to interact with biological receptors or enzymes. Its value lies in its chemical properties as a synthetic intermediate, enabling the construction of complex peptides and pharmaceutical compounds.

| 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].
Fmoc-Lys(Dde)-OH does not exhibit pharmacological activity in vitro. As a protected amino acid derivative, it is a synthetic intermediate rather than a bioactive compound. In vitro studies using this compound focus on its chemical reactivity, such as its use in peptide bond formation reactions and selective deprotection strategies, rather than assessments of pharmacological activity. The compound may be used as a substrate in enzymatic assays to study the cleavage of protecting groups, but these are analytical applications rather than pharmacological assessments. The compound does not bind to receptors, inhibit enzymes, or produce cytotoxic effects in cell-based assays at concentrations typically used for synthesis. Its role in research is almost exclusively as a reagent for organic synthesis. |
| ln Vivo |
Fmoc-Lys(Dde)-OH is not a pharmacologically active compound and therefore does not have defined in vivo activity as a drug. When administered to animals, the compound would likely be metabolized to release lysine, which would then enter normal metabolic pathways. However, the compound is not used therapeutically, and its in vivo effects would be limited to those of the released lysine. Its primary value remains in synthetic chemistry, where it serves as a building block for the preparation of peptides and pharmaceutical compounds.

| Enzyme Assay |
In vitro assays for Fmoc-Lys(Dde)-OH are primarily focused on its chemical properties and reactivity rather than biological activity. Standard protocols in Fmoc-based solid-phase peptide synthesis involve the use of this compound as an orthogonally protected lysine building block. The compound is typically dissolved in polar aprotic solvents such as DMF or DCM and coupled to a growing peptide chain on a solid support using standard peptide coupling reagents such as HATU, HOBt, or DIC. The progress of the coupling reaction can be monitored by HPLC or TLC. The Fmoc group can be removed under basic conditions (e.g., 20% piperidine in DMF), and the Dde group can be selectively removed with 2% hydrazine in DMF, enabling the synthesis of branched or labeled peptides.
|
| Cell Assay |
In vitro cellular assays using Fmoc-Lys(Dde)-OH are not commonly performed because the compound lacks intrinsic biological activity. The compound is used exclusively in synthetic chemistry applications and is not designed for cell culture studies. Its use is confined to the laboratory, where it serves as a building block for the preparation of peptides and pharmaceutical compounds.
|
| Animal Protocol |
In vivo animal studies with Fmoc-Lys(Dde)-OH are not typically conducted, as the compound is a synthetic intermediate rather than a pharmacologically active agent. If used in vivo, the compound would be administered to animals to study the metabolism of protected amino acid derivatives. However, such studies are rare, and the compound is generally used exclusively in synthetic chemistry applications. Its use is confined to the laboratory, where it serves as a building block for the preparation of peptides and pharmaceutical compounds.
|
| ADME/Pharmacokinetics |
Fmoc-Lys(Dde)-OH is not a drug candidate, and pharmacokinetic data are not available. As a protected amino acid derivative, it is designed for chemical synthesis rather than systemic administration. If administered in vivo, the compound would likely be metabolized to release lysine. The compound's pharmacokinetic properties have not been characterized, and its use is confined to in vitro synthetic applications.
|
| Toxicity/Toxicokinetics |
The compound is generally considered to have low toxicity, consistent with its use as a chemical reagent. The compound is classified with hazard statements H302, H312, H315, H319, H332, and H335. Standard laboratory safety precautions, including the use of personal protective equipment, are recommended. Inhalation, ingestion, or skin contact should be avoided.

| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.5 mg/mL (4.69 mM) (saturation unknown) in 10% DMSO + 40% PEG300 +5% Tween-80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 + to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution. (Please use freshly prepared in vivo formulations for optimal results.) |

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
