Biological Activity
Lower concentrations of Fluensulfone delay development: 100 μM Fluensulfone causes a slight delay as at 66 h fewer worms have reached the adult stage whilst at 300 μM no worms reach the adult stage at 66 h and some fail to reach L4. Adult hermaphrodites lay fewer eggs in the presence of 1 mM Fluensulfone. Fluensulfone is also found to reduce the viability of eggs. After 3 h incubation with 100 μM to 1 mM Fluensulfone the thrashing rate is significantly inhibited, with maximal inhibition occurring with 1 mM. After 1 h both 300 μM and 1 mM Fluensulfone cause a significant and reversible inhibition of pharyngeal pumping relative to the vehicle control. Fluensulfone (500 μM) inhibits the frequency of body bends in one day old adult hermaphrodites off food after 2 h exposure[1].

Solvent & Solubility
DMSO : 100 mg/mL (342.82 mM; Need ultrasonic; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
H2O : 0.73 mg/mL (2.50 mM; Need ultrasonic)
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.
* Note: If you choose water as the stock solution, please dilute it to the working solution, then filter and sterilize it with a 0.22 μm filter before use.

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 (8.57 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.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 2.5 mg/mL (8.57 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.
Protocol
For these assays worms of different developmental stages are incubated in liquid with and without Fluensulfone for up to 24 h, and paralysis is scored. 400 μL of M9 phosphate buffer with either Fluensulfone (100 μM, 200 μM or 1 mM) or vehicle (0.5% acetone) is put into each well of a 24 well plate (5 replicates for each Fluensulfone concentration). 5 μL suspension of age synchronised C. elegans (L1, L2/3, L4 or one day old adult) is added to each well. Each well contains approximately 50 to100 worms. The number of worms not moving at 1, 2, 3, 4, 5, 6 and 24 h is determined. The experiment is conducted on two separate occasions with five replicates[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
Groups of 10 female specific pathogen-free CD-1 mice each are treated with untreated diet, diet containing 1200 mg/kg Fluensulfone (high dose in carcinogenicity study), or 1305 mg/kg of isoniazid as a positive control substance for 3 or 7 days, respectively. Two and 14 h before sacrifice, the animals are injected ip with 100 μL of a 10 mg/mL aqueous bromodeoxyuridine (BrdU)-solution. Sacrifice by exsanguination under deep irreversible pentobarbital narcosis is performed early in the morning to assure that the animals are exposed to the test item until shortly before sacrifice[2].
