Fenoxaprop-P-ethyl
Based on 1 Customer Validation
Fenoxaprop-P-ethyl is an acetyl-CoA carboxylase (ACC) inhibitor and post-emergence herbicide. Fenoxaprop-P-ethyl inhibits the conversion of acetyl-CoA to malonyl-CoA, reduces malonyl-CoA synthesis and disrupts fatty acid synthesis. Fenoxaprop-P-ethyl disrupts lipid homeostasis through cascaded inhibition of lipid metabolism, decreases total lipid content, downregulates fatty acid elongase genes and inhibits their activity. Fenoxaprop-P-ethyl disrupts fatty acid synthesis in rice seedlings and controls annual monocotyledonous weeds in wheat, durum wheat, rye, triticale and barley fields.

Activité biologique
Fenoxaprop-P-ethyl (0.4 mg/L; 1 h immersion) downregulates genes encoding fatty acid elongation enzymes (KCS, KCR, HCD, ECR) in rice (Oryza sativa variety 9311) seedling stem and leaf tissue 2 days post-treatment, and time-dependently inhibits their activities[1].
Fenoxaprop-P-ethyl produces positive results in the in vitro chromosome aberration assay in human lymphocytes[2].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
Fenoxaprop-P-ethyl (92.1 mL/ha) poses a low risk to most healthy invertebrate organisms, except for a high in-field risk to non-target arthropods when using the CHA 4960 formulation[2].
Fenoxaprop-P-ethyl and most of its metabolites pose a low risk to healthy aquatic organisms, but a high risk is identified in specific FOCUS surface water scenarios for fenoxaprop-P, fenoxaprop-M, and phenol metabolite[2].

Solvant et solubilité
DMSO : ≥ 100 mg/mL (276.41 mM; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
* "≥" means soluble, but saturation unknown.
Please refer to the solubility information to select the appropriate solvent. Once prepared, please aliquot and store the solution to prevent product inactivation from repeated freeze-thaw cycles.
Storage method and period of stock solution: -80°C, 2 years; -20°C, 1 year. When stored at -80°C, please use it within 2 years. When stored at -20°C, please use it within 1 year.

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2.5 mg/mL (6.91 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.

The co-solvents required include: DMSO, . All of co-solvents are available by MedChemExpress (MCE). , Tween 80. All of co-solvents are available by MedChemExpress (MCE).
Working solution concentration: 0.22 mg/mL
Method for preparing stock solution: mg drug dissolved in μL DMSO. Stock solution concentration: mg/mL.
1. Take μL DMSO stock solution;
2. Add μL .
μL , mix evenly;
3. Then add μL Tween 80, mix evenly;
4. Then add μL
Please ensure that the stock solution in the first step is dissolved to a clear state, and add co-solvents in sequence. You can use ultrasonic heating (ultrasonic cleaner, recommended frequency 20-40 kHz), vortexing, etc. to assist dissolution.
