Kaempferol‐3‐O‐sophoroside (PCS‐1) contributes to modulation of depressive‐like behaviour in C57BL/6J mice by activating AMPK

PCS-1 binds to AMPK to promote BDNF production and autophagy enhancement, ultimately achieving antidepressant effects. This study provides support for the clinical application of saffron petals and provides further evidence for AMPK as a potential target for antidepression.
