| Targets |
This compound does not have a specific biological target; it functions as a chemical building block for peptide synthesis. As a homolysine derivative, it is used to introduce homolysine residues into peptides. The Fmoc group protects the α-amino group for standard Fmoc SPPS, while the Boc group protects the side-chain amino group. Homolysine is a lysine homolog with an extended side chain that can modulate ion-pairing interactions in SAR studies.

| 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 protected amino acid building block. Amino acid derivatives have been commercially used as ergogenic supplements affecting the release of anabolic hormones. However, Fmoc-hLys(Boc)-OH itself is primarily used as a research tool in peptide synthesis rather than as a directly active pharmacological agent. |
| ln Vivo |
This compound is not administered in vivo as a therapeutic agent. It is a research chemical utilized as a building block in peptide synthesis. The final deprotected peptide product, not this protected intermediate, would be the subject of in vivo pharmacological testing for therapeutic efficacy and safety. The protected homolysine derivative itself is never administered to animals as a test compound. It is a lysine analogue.
|
| Enzyme Assay |
Non-cellular enzyme/receptor binding assays are not applicable to Fmoc-hLys(Boc)-OH as it is not biologically active. Its use is in organic synthesis and peptide chemistry. A typical protocol involves its use as a building block in Fmoc SPPS, where the Fmoc group is removed with a base (e.g., piperidine) to allow for coupling with the next amino acid, and the Boc group can be selectively removed under acidic conditions for side-chain modifications. It has been used to modulate ion-pairing interactions in SAR studies.
|
| Cell Assay |
This compound is not used in cell-based assays as a therapeutic agent. Its role is as a research chemical and building block for peptide synthesis. It should be stored at 4°C or -20°C. It is a powder. Purity is typically 98%. 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 Fmoc-hLys(Boc)-OH as a test article. It is a chemical intermediate used in the synthesis of peptide-based drug candidates. If used to synthesize a therapeutic peptide, that final product would be subjected to animal testing. The protected homolysine derivative itself is not administered to animals as a therapeutic agent. It is a lysine analogue.
|
| ADME/Pharmacokinetics |
Pharmacokinetic properties are not applicable to Fmoc-hLys(Boc)-OH as it is not a drug. It is a small molecule (MW 482.57 g/mol) with the formula C27H34N2O6. Its properties are relevant for chemical handling and storage rather than for systemic exposure studies. The Fmoc and Boc protecting groups are designed for synthetic utility, not for bioavailability.
|
| Toxicity/Toxicokinetics |
The toxicity of Fmoc-hLys(Boc)-OH is not extensively documented, as it is a research chemical not intended for human or veterinary use. It should be handled with standard laboratory precautions, including the use of appropriate personal protective equipment and working in a well-ventilated area. The compound is a powder and should be stored at 4°C or -20°C. It is not intended for diagnostic, therapeutic, or other medical applications.

| Additional Infomation |
Fmoc-hLys(Boc)-OH (Fmoc-L-homolysine(Boc)-OH) is a protected, non-proteinogenic amino acid derivative that functions as a homolysine building block in solid-phase peptide synthesis (SPPS). Homolysine is a lysine homolog with an extended side chain that has been used to modulate ion-pairing interactions between Lys and enzyme carboxylate groups in SAR studies. It is a lysine analogue. It is not a pharmaceutical.
