MedKoo Cat#: 503210 | Name: PF-3845
Featured

Description:

WARNING: This product is for research use only, not for human or veterinary use.

PF-3845 is a fatty acid amide hydrolase (FAAH) inhibitor, and acts in the nervous system to reverse LPS-induced tactile allodynia in mice. PF-3845 promotes neuronal survival, attenuates inflammation and improves functional recovery in mice with traumatic brain injury. Treatment with PF3845 inactivated FAAH activity and enhanced the AEA levels in the brain. It reduced neurodegeneration in the dentate gyrus, and up-regulated the expression of Bcl-2 and Hsp70/72 in both cortex and hippocampus. PF3845 also suppressed the increased production of amyloid precursor protein, prevented dendritic loss and restored the levels of synaptophysin in the ipsilateral dentate gyrus.

More Info
Fatty acid amide hydrolase (FAAH) is an enzyme that catalyzes N-acyl ethanolamines (NAEs), including the endocannabinoid arachidonoyl ethanolamide (AEA).  PF-3845. Mechanistic and structural studies confirm that PF-3845 is a covalent inhibitor that carbamylates FAAH's serine nucleophile. PF-3845 selectively inhibits FAAH in vivo, as determined by activity-based protein profiling; raises brain anandamide levels for up to 24 hr; and produces significant cannabinoid receptor-dependent reductions in inflammatory pain. These data thus designate PF-3845 as a valuable pharmacological tool for in vivo characterization of the endocannabinoid system. ( source: Chem Biol. 2009 Apr 24;16(4):411-20 .)

Biological target:
PF-3845 is a potent, selective, irreversible and orally active inhibitor of fatty acid amide hydrolase (FAAH), with a Ki of 0.23 µM.
In vitro activity:
This study found that of all the inhibitors used, the FAAH inhibitor PF-3845 reduced the Colo-205 cell line viability the most effectively (IC50=52.55 μM). This study also showed that the effect of decreased cell viability was enhanced when Colo-205 cells were incubated with PF-3845 and RN-1734, a TRPV4 antagonist (IC50=30.54 μM). Western blot assay revealed significantly decreased CB1 receptor expression levels, while CB2 expression was increased in response to PF-3845 when compared to control. Furthermore, PF-3845 inhibited migration and invasion of Colo-205 cell line. Reference: Acta Biochim Pol. 2017;64(3):519-525. https://pubmed.ncbi.nlm.nih.gov/28850633/
In vivo activity:
FAAH (-/-) mice or wild-type mice treated with FAAH inhibitors (URB597, OL-135 and PF-3845) displayed an anti-allodynic phenotype. Furthermore, i.p. PF-3845 increased AEA levels in the brain and spinal cord. Additionally, intraplantar PF-3845 produced a partial reduction in allodynia.
