Lauflumide
Based on 1 Customer Validation
Lauflumide (BisfluoroModafinil) is a selective dopamine reuptake inhibitor and wake-promoting agent. Lauflumide inhibits the dopamine transporter (DAT). Lauflumide induces sustained wakefulness without eliciting hyperlocomotion, stereotypy or abnormal behaviors in Mus musculus (house mice). Lauflumide reduces non-rapid eye movement (NREM) sleep rebound in rats, modulates electroencephalogram (EEG) spectral composition, and produces anti-aggressive effects. Lauflumide alleviates circadian rhythm disturbances in rats, increases spontaneous activity in fatigued rats, and facilitates their recovery from severe fatigue. Lauflumide can be used in research related to excessive daytime sleepiness as well as chronic severe fatigue/chronic fatigue syndrome (CFS).

Actividad biológica
Lauflumide (16-64 mg/kg; administered daily for 3 times) dose-dependently and persistently enhances spontaneous locomotor activity in fatigued rats, and the improvement of fatigue-induced circadian rhythm impairment at the 16 mg/kg dose is comparable to that of 64 mg/kg Modafinil[2].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Induced 170 minutes of locomotor activity at 256 mg/kg.
Increased sleep latency to 208 minutes at 64 mg/kg (vs. 55.92 minutes for vehicle).
Extended net wakefulness duration by 151 minutes at 64 mg/kg, significantly longer than modafinil's net wakefulness duration.
Reduced light period NREM sleep to 254.41 minutes (vs. 342.02 minutes for vehicle) at 64 mg/kg.
Reduced light period REM sleep to 40.67 minutes (vs. 49.84 minutes for vehicle) at 64 mg/kg.
Reduced light period wakefulness to 223.30 minutes (vs. 273.37 minutes for vehicle) at 64 mg/kg.
Caused NREM sleep loss of -87.61 minutes and REM sleep loss of -9.18 minutes during light period at 64 mg/kg.
Increased relative power density in 0.75-3.25 Hz range and decreased relative power density in 6.25-7.25 Hz range during NREM sleep.
Decreased relative theta power density during REM sleep.
Increased relative low delta power in 0.75-1.25 Hz range during wakefulness.
Increased delta power during the first 2 time intervals post-sleep onset of recovery NREM sleep.

Animal Model:Sprague-Dawley (male, 7-8 weeks old, chronic severe fatigue model via 7-day consecutive fatigue procedure)[2]
-
Dosage:16 mg/kg; 32 mg/kg; 64 mg/kg
-
Administration:three daily doses
-
Result:Increased dark-phase locomotor activity significantly at 16, 32, and 64 mg/kg.
Increased light-phase locomotor activity to a lesser extent.
Reduced fatigue-induced circadian rhythm impairment at 16 mg/kg to a similar magnitude as modafinil at 64 mg/kg.
Exhibited more sustainable effect on dark-phase activity than modafinil.

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
