Taraxerol has anti-inflammatory and anticancer effects. Taraxerol attenuates acute inflammation by inhibiting NF-κB signaling[5,6].
Taraxerol downregulates the expression of proinflammatory mediators in macrophages by interfering with the activation of TAK1 and Akt, thus preventing NF-κB activation[3].
Taraxerol enhanced ROS levels and attenuated the MMP (Δψm) in HeLa cells. Taraxerol induced apoptosis mainly via the mitochondrial pathway including the release of cytochrome c to the cytosol and activation of caspases 9 and 3, and anti-poly (ADPribose) polymerase (PARP). Taraxerol could induce the down-regulation of the anti-apoptotic protein Bcl-2 and up-regulation of pro-apoptotic protein Bax. It suppressed the PI3K/ Akt signaling pathway [1].
Taraxerol treatment significantly attenuated carrageenan induced paw edema 2 h onward. The anti-inflammatory effect of taraxerol was sustained up to 4 h[2]. Taraxerol (20mg/kg, p.o.) treatment stimulated glucose metabolism in skeletal muscle, regulated blood glycaemic status and lipid profile in the sera, reduced the secretion of pro-inflammatory cytokines, and restored the renal physiology in T2D rats[4]. AChE activity inhibition in animals and indicate that Taraxerol has anti-amnesic activity that may hold significant therapeutic value in alleviating certain memory impairments observed in AD[7].

Taraxerol 具有抗炎和抗癌作用。蒲公英甾醇通过抑制 NF-κB 信号通路减轻急性炎症[5,6]。
紫杉醇通过干扰 TAK1 和 Akt 的激活来下调巨噬细胞中促炎介质的表达，从而阻止 NF-κB 激活[3]。
紫杉醇增强了 HeLa 细胞中的 ROS 水平并减弱了 MMP (δψm)。 Taraxerol 主要通过线粒体途径诱导细胞凋亡，包括将细胞色素 c 释放到胞质溶胶和半胱天冬酶 9 和 3 的激活，以及抗多聚 (ADPribose) 聚合酶 (PARP)。 Taraxerol 可诱导抗凋亡蛋白 Bcl-2 的下调和促凋亡蛋白 Bax 的上调。抑制PI3K/Akt信号通路[1]。
2 小时后，紫杉醇处理可显着减轻角叉菜胶诱导的爪水肿。蒲公英甾醇的抗炎作用可持续长达4 h[2]。蒲公英甾醇（20 毫克/千克，口服）治疗可刺激骨骼肌中的葡萄糖代谢，调节血糖状态和血清中的脂质分布，减少促炎细胞因子的分泌，并恢复 T2D 大鼠的肾脏生理机能[4] 。动物 AChE 活性抑制表明 Taraxerol 具有抗遗忘活性，在减轻 AD[7] 中观察到的某些记忆障碍方面可能具有重要的治疗价值。
