| Targets |
Propargyl-PEG2-amine is a chemical linker, not a pharmacological target. It is used to connect a ligand for an E3 ubiquitin ligase to a ligand for a target protein in PROTAC design, or to conjugate drugs to antibodies in ADC synthesis.
|
|---|---|
| ln Vitro |
ADC is made up of antibodies that are connected by an ADC linker to the ADC cytotoxin. Two distinct ligands, one for the E3 ubiquitin ligase and the other for the target protein, are present in PROTAC and are connected by a linker. PROTAC targets and selectively degrades target proteins by means of the intracellular ubiquitin-proteasome system.
Propargyl-PEG2-amine is not evaluated for direct biological activity in vitro. Its utility lies in its chemical properties, such as the alkyne group for click chemistry and the amine for amide coupling, which facilitate the synthesis of bioconjugates. |
| ln Vivo |
Propargyl-PEG2-amine is not used as a pharmacological agent in vivo. It is a chemical tool used in the synthesis of PROTACs and ADCs, which are then evaluated for their biological activity in animal models.
|
| Enzyme Assay |
There are no standard cell-free enzyme or receptor binding assays for Propargyl-PEG2-amine itself, as it is not a bioactive compound. Its chemical properties, such as reactivity in click chemistry and amide coupling, are characterized using analytical techniques like NMR and HPLC.
|
| Cell Assay |
In vitro cellular assays are not performed for Propargyl-PEG2-amine directly. Instead, the PROTACs or ADCs synthesized using this linker are evaluated for their ability to degrade target proteins or deliver cytotoxic payloads to cancer cells.
|
| Animal Protocol |
Propargyl-PEG2-amine is not used in animal experiments directly. The PROTACs or ADCs synthesized with this linker are administered to animal models to evaluate their pharmacokinetics, efficacy, and toxicity.
|
| ADME/Pharmacokinetics |
Propargyl-PEG2-amine (C7H13NO2) has a molecular weight of 143.18 g/mol. Its chemical name is 2-(2-(prop-2-yn-1-yloxy)ethoxy)ethanamine. It is a PEG-based PROTAC linker that can be used in the synthesis of PROTACs. It is a click chemistry reagent, containing an alkyne group.
|
| Toxicity/Toxicokinetics |
The toxicity of Propargyl-PEG2-amine is related to its chemical properties as a PEG-based linker and alkyne compound. It should be handled with appropriate safety precautions, as detailed toxicological data are limited. Its use is primarily in research and development for bioconjugation applications.

| Solubility (In Vitro) |

| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.5 mg/mL (17.46 mM) (saturation unknown) in 10% DMSO + 40% PEG300 + 5% Tween80 + 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. Solubility in Formulation 2: ≥ 2.5 mg/mL (17.46 mM) (saturation unknown) in 10% DMSO + 90% (20% SBE-β-CD in 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 900 μL of 20% SBE-β-CD physiological saline solution and mix evenly. Preparation of 20% SBE-β-CD in Saline (4°C，1 week): Dissolve 2 g SBE-β-CD in 10 mL saline 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.
