| Targets |
As a chemical linker for ADC synthesis, Fmoc-Gly-NH-CH2-O-CH2COOH does not have a defined biological target. Its role is to serve as a connector between an antibody and a cytotoxic payload in antibody-drug conjugates. The Fmoc group allows for selective deprotection and further functionalization. The compound facilitates the covalent attachment of cytotoxic drugs to monoclonal antibodies.
|
|---|---|
| ln Vitro |
In cell-free biochemical systems, this linker is used to synthesize antibody-drug conjugates. The Fmoc group can be removed to reveal a free amine for conjugation to the antibody, while the carboxylic acid group provides a handle for payload attachment. The linker facilitates the covalent attachment of cytotoxic drugs to monoclonal antibodies.
|
| ln Vivo |
This compound does not exhibit direct cellular activity as it is a chemical linker rather than a bioactive molecule. Antibody-drug conjugates constructed using this linker can be delivered to target cells where the antibody binds to cell surface antigens, followed by internalization and intracellular release of the cytotoxic payload. The targeted delivery enables selective killing of tumor cells.
|
| Enzyme Assay |
The cell-free assay for this linker involves conjugation reactions between the linker and the antibody or payload. The Fmoc group can be removed under basic conditions (e.g., piperidine) to reveal a free amine for conjugation. The carboxylic acid group can be activated for payload attachment using EDC or HATU. The efficiency of conjugation is assessed by mass spectrometry, SDS-PAGE, or HPLC analysis.
|
| Cell Assay |
No cell-based experimental protocols are directly applicable to this linker as it is a chemical synthesis reagent. Antibody-drug conjugates synthesized using this linker can be evaluated in cell culture experiments. Typical protocols include treating cancer cell lines with the ADC at concentrations ranging from 0.001 to 10 μg/mL. Cells are incubated for 24-96 hours, and cell viability is assessed using MTT or CCK-8 assays.
|
| Animal Protocol |
This linker is not administered to animals as it is a chemical intermediate for ADC synthesis. Antibody-drug conjugates incorporating this linker may be evaluated in animal models for pharmacokinetics and efficacy. Typical studies involve administration of the ADC to tumor-bearing mice via intravenous routes at doses ranging from 0.1-10 mg/kg. Tumor volumes are measured, and tissues are collected for analysis.
|
| ADME/Pharmacokinetics |
As a chemical reagent, this compound does not have established pharmacokinetic properties. The pharmacokinetics of ADCs incorporating this linker depend on the antibody, payload, and overall conjugate properties. The compound itself is not intended for therapeutic use and is not administered systemically.
|
| Toxicity/Toxicokinetics |
The compound is not intended for therapeutic use and lacks established toxicity profiles. Standard laboratory safety precautions should be observed when handling this chemical reagent. The compound is typically stored at low temperatures for research use. It is for research use only and is not for human therapeutic applications.

Note: Listed below are some common formulations that may be used to formulate products with low water solubility (e.g. < 1 mg/mL), you may test these formulations using a minute amount of products to avoid loss of samples.
Injection Formulations
Injection Formulation 1: DMSO : Tween 80： Saline = 10 : 5 : 85 (i.e. 100 μL DMSO stock solution → 50 μL Tween 80 → 850 μL Saline)(e.g. IP/IV/IM/SC) *Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH ₂ O to obtain a clear solution. Injection Formulation 2: DMSO : PEG300 ：Tween 80 : Saline = 10 : 40 : 5 : 45 (i.e. 100 μL DMSO → 400 μLPEG300 → 50 μL Tween 80 → 450 μL Saline) Injection Formulation 3: DMSO : Corn oil = 10 : 90 (i.e. 100 μL DMSO → 900 μL Corn oil) Example: Take the Injection Formulation 3 (DMSO : Corn oil = 10 : 90) as an example, if 1 mL of 2.5 mg/mL working solution is to be prepared, you can take 100 μL 25 mg/mL DMSO stock solution and add to 900 μL corn oil, mix well to obtain a clear or suspension solution (2.5 mg/mL, ready for use in animals).
