PG - 255-65 LID - S0306-4522(15)00099-8 [pii] LID - 10.1016/j.neuroscience.2015.01.044 [doi] AB - In this study, a novel TRI (triple reuptake inhibitors) antidepressant candidate RO-05 (4-[1-[1-(benzoyloxy)cyclohexyl]-2-(dimethylamino)ethyl]-phenyl benzoate) was investigated in TST (tail suspension test), FST (forced swimming test) and CMS (chronic mild stress) model. Results showed RO-05 significantly decreased the immobility time in FST and TST at 4.5-, 9-, 18-mg/kg in rats and 9-, 18-, 36-mg/kg in mice. Chronic administration of 18-mg/kg RO-05 improved the behavioral index, anhedonia and normalized the hyperactivity of HPA (hypothalamic-pituitary-adrenal axis) of CMS rats. We further investigated the possible mechanisms of RO-05 in the CMS model. Eighteen milligrams per kilogram of RO-05 chronic administration significantly reversed the increase of mRNA and protein expression of FKBP5 in the CMS rat hippocampus, which facilitated the activation of GR- (glucocorticoid receptor) and GR-responsive gene Foxo1 expression. RO-05 also elevated the expression of BDNF (brain-derived neurotrophic factor) in CMS rat hippocampus. In summary, our results indicated that RO-05 is a promising antidepressant candidate. The possible antidepressant mechanisms of RO-05 were the modulation of FKBP5 expression, GR activation, corresponding inhibition of HPA axis hyperactivity, and the increase of BDNF expression.
