Background:
Desipramine-d4is intended for use as an internal standard for the quantification of desipramine by GC- or LC-MS. Desipramine is a tricyclic antidepressant and an active metabolite of imipramine .1It inhibits the serotonin (5-HT) and norepinephrine transporters (Kis = 163 and 3.5 nM for human SERT and NET, respectively) and is an antagonist of the 5-HT receptor subtype 5-HT2Aand the α1-adrenergic receptor (α1-AR), as well as histamine H1and muscarinic acetylcholine receptors (mAChRs; Kis = 115, 23, 31, and 37 nM, respectively). Desipramine is selective for the 5-HT2Areceptor over the 5-HT1Areceptor (Ki= 2,272 nM) and for α1-AR over α2-AR (Ki= 1,379 nM). It also selectively inhibits G protein-activated inward rectifier potassium channel (GIRK), also known as Kir3, currents inXenopusoocytes expressing human GIRK1 and GIRK2 or human GIRK1 and GIRK4 (IC50s = 36.4 and 53.9 µM, respectively) over Kir1.1 or Kir2.1 currents inXenopusoocytes expressing the human channels (IC50s = >100 µM for both).2Desipramine (3.2 mg/kg) decreases immobility time in the forced swim test in mice.3It also decreases flinching, as well as paw biting and licking, in the second phase of the formalin test in rats.4Formulations containing desipramine have been used in the treatment of depression.
