| Description | PMSF (Phenylmethylsulfonyl fluoride) is an irreversible inhibitor of serine/cysteine protease and is often used in the preparation of cell lysates. |
| Targets & IC50 | hypothermia (mouse):224 mg/kg (ED50), Neutrophil:95 μM, Neutrophil:130.9 μM, Neutrophil:22.8 μg/mL, Remain immobile (mouse):206 mg/kg (ED50), antinociception (mouse):86 mg/kg (ED50) |
| In vitro | Treatment with PMSF (intraperitoneal injection) in mice elicits cannabinoid-like effects, providing analgesia (ED50: 86 mg/kg), hypothermia (ED50: 224 mg/kg), and catalepsy (ED50: 206 mg/kg). When administered to Sprague-Dawley rats, PMSF induces a dose-dependent analgesic effect and significantly potentiates the analgesic effect of β-endorphin in vivo. By inhibiting fatty acid amide hydrolase (FAAH) activity, PMSF suppresses typical cannabinoid or Δ(9)-tetrahydrocannabinol-like effects in ICR mice. Pretreatment with 30 mg/kg PMSF before the injection of [3H]-labeled cannabinoids results in a notable increase in brain cannabinoid levels after 5 minutes compared to [3H]-THC. PMSF pretreatment at 30 mg/kg enhances the cannabinoid-induced effects on the tail-flick response (analgesic effect), locomotion, and spontaneous activity by 5, 8, and 10-fold respectively. Administering PMSF 12 hours before paraoxon (PSP) protects hens from delayed neurotoxicity, whereas administration 4 hours later exacerbates the neurotoxic effects. PMSF pretreatment also prevents organophosphate-induced delayed neuropathy in hens and inhibits neuropathilament degeneration induced by tri-ortho-tolyl phosphate. |
| In vivo | METHODS: To study the analgesic effect of PMSF, PMSF was intraperitoneally injected into mice. RESULTS: Mice exhibited cannabinoid effects: including analgesia, hypothermia and immobility, with ED50 values of 86, 224 and 206 mg/kg, respectively. |

For example, if the intended dosage is 10 mg/kg for animals weighing 20 g , with a dosing volume of 100 μL per animal, and a total of 10 animals are to be administered, using a formulation of 
10% DMSO+ 40% PEG300+ 5% Tween 80+ 45% Saline/PBS/ddH2O , the resulting working solution concentration would be 2 mg/mL.Dissolve 2 mg of the compound in 100 μL DMSO to obtain a stock solution at a concentration of 20 mg/mL . If the required concentration exceeds the compound's known solubility, please contact us for technical support before proceeding.
1) Add 100 μL of the DMSO stock solution to 400 µL PEG300 and mix thoroughly until the solution becomes clear.
2) Add 50 µL Tween 80 and mix well until fully clarified.
3) Add 450 µL Saline,PBS or ddH2O and mix thoroughly until a homogeneous solution is obtained.
