title: Cipadesin A, a bioactive ingredient of Xylocarpus granatum, produces antidepressant-like effects in adult mice.
abstract: Xylocarpus granatum Koenig, widely used in folk medicine in southeast countries, has been reported to exert neuropharmacological activities as well as mood regulation. The neuroprotective activities of limonoids, riches in X. granatum, are poorly understood.
  
  
  
  To investigate the potential antidepressant-like effects and the underlying mechanisms of cipadesin A, one limonoid component, extracted from X. granatum, in acute stress-induced depression mouse models.
  
  
  
  Antidepressant-like effects of cipadesin A were investigated through behavioral tests, and potential mechanism was assessed by neuroendocrine system.
  
  
  
  Antidepressant-like effects of cipadesin A (5, 15, 50mg/kg/day for 7days, intragastrically) were estimated through forced-swimming test (FST), tail suspension test (TST) and open field test (OFT). Effects of cipadesin A on hypothalamus-pituitary- adrenal (HPA) axis were evaluated by analysis of serum corticosterone (CORT) and adrenocorticotropic hormone (ACTH) using enzyme-linked immunosorbent assay (ELISA).
  
  
  
  Cipadesin A administration significantly reduced the floating time in the FST and immobility time in the TST (15-50mg/kg). Cipadesin A dose-dependently increased the time in the central zone in the OFT (5-50mg/kg), without altering the locomotor activity. Moreover, repeated cipadesin A treatment significantly inhibited the increase levels of serum CORT (5-50mg/kg), ACTH (15-50mg/kg) following the forced swimming, but not in the absence of stress.
  
  
  
  Cipadesin A has antidepressant-like activities in acute stressed mice model of depression, which likely occurs by inhibiting the HPA axis activity response to stress. These data support further exploration for developing cipadesin A as a potential agent to treat depression and anxiety disorders.
