Flibanserin-d4 (hydrochloride)

Flibanserin-d4 is intended for use as an internal standard for the quantification of flibanserin (Cay-19203) by GC- or LC-MS. Flibanserin is a full agonist of the serotonin 5-HT1A receptor and an antagonist of 5-HT2A (Kis = 1 and 49 nM, respectively). It also binds to dopamine D4 receptors with Ki values ranging from 4-24 nM, but demonstrates no affinity for the other 5-HT subtypes or other neurotransmitter receptors. In vitro, flibanserin has been shown to reduce forskolin-stimulated cAMP formation in cells and rat tissues and to antagonize the accumulation of phosphatidyl inositol turnover induced by 5-HT in the mouse cortex. At 10 mg/kg, flibanserin can reduce serotonin in the prefrontal cortex and dorsal raphe of conscious rats while increasing extracellular noradrenaline and dopamine.Formal Name: 1,3-dihydro-1-[2-[4-[3-(trifluoromethyl)phenyl]-1-piperazinyl]ethyl-1,1,2,2-d4]-2H-benzimidazol-2-one, monohydrochloride.
