Pulchinenoside A is a natural triterpenoid saponin that enhances synaptic plasticity in the adult mouse hippocampus and facilitates spatial memory in adult mice.
体外研究: Additions of pulsatilloside A and anemoside A3, at dosages ranging from 0.1, 1 and 10 μg/ml, protected PC12 cells from apoptosis. [1]
In vivo:AA3 also acts as a non-competitive NMDA receptor (NMDAR) modulator with a neuroprotective capacity against ischemic brain injury and overexcitation in rats. [2] Anemoside A3 produces relaxation in rat renal arteries through multiple mechanisms. [3]
