| ln Vitro |
In vitro, 4-bromotetrahydropyran is primarily used as a chemical reagent and synthetic intermediate. It is used in nickel-catalyzed alkyl-alkyl Suzuki coupling reactions with boron reagents. The compound is also used in the preparation of selective small-molecule melanocortin-4 receptor agonists. As a brominated tetrahydropyran, it is a building block for the synthesis of various biologically active compounds.
|
| ln Vivo |
In vivo activity data for 4-bromotetrahydropyran itself are not available, as the compound is not intended for direct in vivo administration. Rather, it is a precursor used in the synthesis of melanocortin-4 receptor agonists and other drug candidates that are subsequently evaluated in animal models. The compound's in vivo relevance is indirect, through the biological activities of the final pharmaceutical compounds derived from its tetrahydropyran scaffold.

| Cell Assay |
For in vitro cell-based experiments, 4-bromotetrahydropyran is used as an intermediate in the synthesis of compounds that are tested in cell viability, proliferation, and cytotoxicity assays. The compound itself is not typically evaluated in cell-based assays. Standard cell culture protocols for test compounds synthesized from this intermediate involve dissolving the final product in DMSO and diluting to working concentrations in appropriate cell culture medium.
|
| Animal Protocol |
In vivo animal studies using 4-bromotetrahydropyran are conducted on the final drug compounds synthesized from it, not on the intermediate itself. For melanocortin-4 receptor agonists derived from this building block, efficacy studies would typically be performed in mouse models of sexual dysfunction or obesity. Standard in vivo protocols involve administration to rodents via oral gavage or intraperitoneal injection.

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).

*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.
