| Targets |
Fmoc-Ser-OMe does not have a specific pharmacological target as it is a protected amino acid derivative used as a synthetic intermediate. Its function is to serve as a building block for the synthesis of peptides and peptide-like molecules. The Fmoc protecting group is used to selectively protect the amine functionality during peptide synthesis, allowing for the controlled assembly of peptide chains. The methyl ester protecting group protects the carboxylic acid, allowing for selective deprotection and functionalization. Serine is a polar amino acid that plays important roles in protein structure and function.

|---|---|
| ln Vitro |
In vitro, Fmoc-Ser-OMe is used as a synthetic intermediate in peptide synthesis. The compound is used to incorporate serine into peptides and peptide-like molecules using solid-phase peptide synthesis (SPPS). In SPPS, the compound is coupled to a resin-bound peptide chain using standard coupling reagents such as HATU, HOBt, or DIC. The Fmoc protecting group is removed using piperidine to expose the amine for the next coupling step. The methyl ester protecting group can be removed by hydrolysis. Serine-containing peptides are important for various biological functions and are used in drug discovery and chemical biology.
|
| ln Vivo |
Fmoc-Ser-OMe is not used as a therapeutic agent but as a synthetic intermediate for the preparation of peptide-based compounds. The compound itself is not biologically active and is used solely as a chemical building block. The compound may be used in the synthesis of peptide drugs or chemical probes that contain serine residues. Serine is an important amino acid that is involved in various biological processes including protein phosphorylation, enzyme catalysis, and protein-protein interactions. However, Fmoc-Ser-OMe is a protected precursor that requires deprotection to yield the active peptide.
|
| Enzyme Assay |
In vitro synthetic procedures using Fmoc-Ser-OMe typically involve solid-phase peptide synthesis techniques. The compound is dissolved in appropriate solvents such as DMF or NMP for coupling reactions. In SPPS, the compound is activated using coupling reagents such as HATU, HOBt, or DIC and coupled to resin-bound peptides. The Fmoc protecting group is removed using 20% piperidine in DMF. The methyl ester protecting group is typically removed by hydrolysis using base such as NaOH or LiOH. The compound's purity and identity are confirmed by HPLC and mass spectrometry.
|
| Cell Assay |
Cell-based assays using Fmoc-Ser-OMe are not typical as the compound is a synthetic intermediate rather than a bioactive molecule. However, the compound may be used to synthesize peptides that are tested in cell-based assays. The compound itself would not be expected to have significant biological activity due to the presence of the protecting groups. For studies involving serine-containing peptides, the protected compound would be used in peptide synthesis, and the final peptide would be deprotected before testing.
|
| Animal Protocol |
In vivo animal experiments using Fmoc-Ser-OMe are not typical as the compound is a synthetic intermediate rather than a therapeutic agent. The compound may be used in the synthesis of peptide-based drugs that are subsequently tested in animal models. The compound itself is not administered to animals for therapeutic purposes. Its role is limited to chemical synthesis and drug discovery.
|
| ADME/Pharmacokinetics |
Fmoc-Ser-OMe has a molecular weight of 341.36 g/mol and the formula C19H19NO5. The compound is soluble in organic solvents such as DMF, NMP, and DCM. For long-term storage, the compound is kept at -20°C in a dry place, protected from moisture. The compound is stable under normal storage conditions. The Fmoc protecting group can be removed under basic conditions (piperidine), and the methyl ester can be removed by hydrolysis.
|
| Toxicity/Toxicokinetics |
The toxicity of Fmoc-Ser-OMe has not been extensively characterized as the compound is a synthetic intermediate rather than a therapeutic agent. The compound is intended for research use only and is not for human use. Standard laboratory safety precautions should be followed when handling the compound, including the use of gloves and eye protection. The compound may cause irritation to skin, eyes, and respiratory tract upon contact.
