Background:

Trifluoperazine-d₃is intended for use as an internal standard for the quantification of trifluoperazine by GC- or LC-MS. Trifluoperazine (TFP) is a phenothiazine compound with anti-adrenergic and anti-dopaminergic actions typical of antipsychotic agents.¹It antagonizes adrenergic receptors, with selectivity for α₁over the α₂subtypes (K_is = 24, 653, 163, and 391 nM for α_1A, α_2A, α_2B, and α_2C, respectively). TFP binds with much higher affinity to the dopamine D₂-like receptor (K_d= 0.96 nM) compared to the dopamine D₄-like and the serotonin 5-HT_2Areceptors (K_ds = 44 and 135 nM, respectively).²Furthermore, TFP antagonizes calmodulin (CaM) and alters the calcium-binding properties of calsequestrin (CSQ).^3,4TFP has been shown to activate type-2 ryanodine receptors independently of its CaM and CSQ activity.⁴
