Paeoniflorin (Synonyms: 芍藥苷; Peoniflorin)
Paeoniflorin 是一種 heat shock protein 誘導(dǎo)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(qiáng)認(rèn)知能力和減弱學(xué)習(xí)障礙、抗氧化應(yīng)激、抗血小板聚集、擴(kuò)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].
