    K252a decreased the antidepressant action of Rh2 in chronic unpredictable mild stress (CUMS)‐stressed mice. Co‐treatment with (K252a + Rh2) of the mice against CUMS showed the longer immobility time than the (CUMS + Rh2)‐treated mice in the forced swim test (FST)(a) and tail suspension test (TST) (b). K252a blocked the reversing effects of Rh2 on sucrose consumption of the CUMS‐treated mice (c). All data are expressed as the means ± SEM, n = 10. ** p

    The enhancing influence of Rh2 on the expression of BDNF‐CREB signaling pathway was blocked by the inhibitor K252a in mice exposed to chronic unpredictable mild stress (CUMS). BDNF, pERK/ERK, pAKT/AKT, and pCREB/CREB protein levels were lower in (CUMS + Rh2 + K252a)‐treated mice than the (CUMS + Rh2)‐treated mice. The obtained data are expressed as the means ± SEM, n = 5. ** p
