| Targets |
Knorr-2-Chlorotrityl Resin does not have a specific biological target. Its primary utility is as a solid support in peptide synthesis, particularly in the Fmoc strategy. The resin is used to anchor the growing peptide chain, allowing for stepwise peptide assembly. After peptide synthesis is complete, the peptide can be cleaved from the resin under mild acidic conditions. It does not have a therapeutic target but is a key reagent in peptide chemistry.
|
|---|---|
| ln Vitro |
Knorr-2-Chlorotrityl Resin does not exhibit pharmacological activity in vitro. As a solid support for peptide synthesis, it is a chemical reagent rather than a bioactive compound. In vitro studies using this resin focus on its chemical properties, such as its loading capacity and cleavage efficiency. The resin is used in the synthesis of peptides, which may have biological activity, but the resin itself is not active. Its role in research is as a tool for peptide synthesis.
|
| ln Vivo |
Knorr-2-Chlorotrityl Resin is not a pharmacologically active compound and therefore does not have defined in vivo activity as a drug. Its primary value is as a chemical reagent for peptide synthesis. It is not intended for in vivo administration in any therapeutic context. Its use is confined to the laboratory, where it serves as a solid support for the preparation of peptides and peptide-based pharmaceuticals.
|
| Enzyme Assay |
In vitro assays for Knorr-2-Chlorotrityl Resin are focused on its chemical properties and its use in peptide synthesis. Standard protocols involve the use of this resin as a solid support in Fmoc-based solid-phase peptide synthesis (SPPS). The resin is typically swollen in a solvent such as DMF or DCM, and the first amino acid is coupled to the resin. The progress of the peptide synthesis is monitored by standard methods such as the Kaiser test. The cleavage of the peptide from the resin is achieved under mild acidic conditions.
|
| Cell Assay |
In vitro cellular assays using Knorr-2-Chlorotrityl Resin are not performed, as the compound is a solid support used in chemical synthesis rather than a bioactive molecule. Its use is confined to the laboratory for peptide synthesis. The peptides synthesized on this resin may be tested in cellular assays, but the resin itself is not designed for cell culture studies.
|
| Animal Protocol |
In vivo animal studies with Knorr-2-Chlorotrityl Resin are not conducted, as the compound is a chemical reagent rather than a pharmacologically active agent. Its use is confined to the laboratory for peptide synthesis. The peptides synthesized on this resin may be evaluated in animal models, but the resin itself is not administered in vivo.
|
| ADME/Pharmacokinetics |
Knorr-2-Chlorotrityl Resin is not a drug candidate, and pharmacokinetic data are not available. As a solid support for peptide synthesis, it is designed for use in chemical synthesis rather than systemic administration. Its use is confined to in vitro synthetic applications.
|
| Toxicity/Toxicokinetics |
Knorr-2-Chlorotrityl Resin is generally considered to have low toxicity, consistent with its use as a chemical reagent. It is a chlorinated organic compound and should be handled with care. Standard laboratory safety precautions, including the use of personal protective equipment, are recommended. It is not classified as a highly toxic substance, but appropriate safety measures should be followed. Inhalation, ingestion, or skin contact should be avoided.

| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.5 mg/mL (7.98 mM) (saturation unknown) in 10% DMSO + 90% Corn Oil (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 DMSO stock solution (25.0 mg/mL) to 900 μL of corn oil and mix well. (Please use freshly prepared in vivo formulations for optimal results.) |
| Preparing Stock Solutions | 1 mg | 5 mg | 10 mg | |
| 1 mM | 3.1926 mL | 15.9632 mL | 31.9264 mL | |
| 5 mM | 0.6385 mL | 3.1926 mL | 6.3853 mL | |
| 10 mM | 0.3193 mL | 1.5963 mL | 3.1926 mL |
*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.
