BIA 10-2474 is a long-acting reversible inhibitor of fatty acid amide hydrolase (FAAH) that increases levels of the neurotransmitter anandamide in the central nervous system and in peripheral tissues (that is, the rest of the body other than the brain and spinal cord). BIA 10-2474(BIA10-2474) interacts with the human endocannabinoid system. BIA 10-2474(BIA10-2474) was in development for the treatment of a range of different medical conditions from anxiety to Parkinson's disease, also for the treatment of chronic pain of multiple sclerosis, Y, hypertension or the treatment of obesity.

FAAH (rat brain regions):50-70mg/kg (IC50)

ExVivo: BIA 10-2474 proves to be a potent FAAH inhibitor with IC50s of 50-70 mg/kg (i.p.) in various brain regions. IC50 values for brain regions are 52 (cerebellum), 67 (rest of brain), 68 (cortex), and 71 mg/kg (hypothalamus)[1].

In January 2016, severe adverse events (SAE) occurs in the Phase I Clinicalal trial using the drug BIA 10-2474 including one death. The possibilities for failure of trials such as off-target effect, dose calculation, unexpected immune response, species variation, and cumulative dose toxicity would be sought[2].
