Linuron
Based on 1 publication(s) in Google Scholar
Linuron is a phenylurea herbicide widely used to control the growth of grasses and weeds in various crops and orchards. Linuron acts as a photosystem II inhibitor. It also functions as a competitive androgen receptor (AR) antagonist, with an EC50 of 200 μM and a Ki of 100 μM against rat AR, and an EC50 of 20 μM against human AR. Linuron exhibits reproductive toxicity in animals and acts as an endocrine disruptor.\n

Biological Activity
Linuron (10 mg/L; 5 days) inhibits growth of green and etiolated Secale cereale L. cv. Dankowskie Zlote seedlings at 22 °C, but increases seedling biomass at 15 °C and 29 °C, while reducing seedling moisture content at 22 °C[4].
Linuron (10 mg/L; 5 days) increases alkylresorcinol content in green and etiolated Secale cereale L. cv. Dankowskie Zlote seedlings at 29 °C, decreases content at 22 °C, and has no significant effect at 15 °C[4].
Linuron (10 mg/L; 5 days) alters the alkylresorcinol homolog composition of green and etiolated Secale cereale L. cv. Dankowskie Zlote seedlings in a temperature-dependent manner, with major impacts on the dominant AR C17:0 and AR C19:0 homologs[4].

Solvent & Solubility
DMSO : 100 mg/mL (401.46 mM; Need ultrasonic; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
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, 6 months; -20°C, 1 month. When stored at -80°C, please use it within 6 months. When stored at -20°C, please use it within 1 month.

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 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 2.5 mg/mL (10.04 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 900 μL 20% SBE-β-CD in Saline, and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.

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.
