Paeoniflorin (Synonyms: 芍藥苷; Peoniflorin)
Paeoniflorin 是一種 heat shock protein 誘導化合物，普遍存在于芍藥科植物中，具有多種生物活性，包括抗ai活性、抗yan活性、增強認知能力和減弱學習障礙、抗氧化應激、抗血小板聚集、擴張血管和降低血液粘度。
生物活性
Paeoniflorin is a heat shock protein-inducing compound and commonly exists in the plants of Paeoniaceae family, with various biological activities, including anticancer activity, anti-inflammatory activity, enhancing cognition and attenuating learning impairment, anti-oxidative stress, antiplatelet aggregation, expansion of blood vessels, and reducing blood viscosity[1][2][3].
體外研究(In Vitro)
Paeoniflorin (80 μg/mL; 4-24 h) treatment can induce Hsp40 and Hsp27 as well as Hsp70[3].
