Description

PF-3845 is a potent, selective, irreversible and orally active inhibitor of fatty acid amide hydrolase (FAAH), with a Ki of 0.23 µM. PF-3845 is a covalent inhibitor that carbamylates FAAH's serine nucleophile. PF-3845 can reduce pain sensation, inflammation, and anxiety/depression without substantial effects on motility or cognition[1][3].

IC50 & Target

Ki: 0.23 µM (FAAH)[1]

In Vitro

PF-3845 (0.5 nM-10 μM; 40 min) inhibits human FAAH-1 (IC50=18 nM) in a concentration-dependent manner, and shows negligible activity against FAAH-2 (IC50>10 μM) in COS-7 cells[1].
PF-3845 (0.1-1000 μM; 48 h) significantly decreases the Colo-205 cell viability[2].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

In Vivo

PF-3845 (1-30 mg/kg; p.o.) produces cannabinoid receptor-dependent reductions in inflammatory pain in rat[1].
PF-3845 (10 mg/kg; a single i.p.) selectively inhibits FAAH in mice for up to 24 hours[1].
PF-3845 (10 mg/kg; a single i.p.) causes a dramatic and sustained elevation in Anandamide (AEA) in mice[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model: Male Sprague-Dawley rats (200g- 250g) are injected CFA[1]
Dosage: 1, 3, 10, 30 mg/kg
Administration: Oral administration
Result: Caused a dose-dependent inhibition of mechanical allodynia with a minimum effective dose (MED) of 3 mg/kg.

In Vivo:

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.

  • Protocol 1

    Add each solvent one by one:  10% DMSO    40% PEG300    5% Tween-80    45% Saline

    Solubility: ≥ 2.5 mg/mL (5.48 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.
  • Protocol 2

    Add each solvent one by one:  10% DMSO    90% (20% SBE-β-CD in Saline)

    Solubility: ≥ 2.5 mg/mL (5.48 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.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
