Euphol, a major constituent found in Euphorbia tirucalli effectively inhibited via a reversible mechanism, the monoacylglycerol lipase (MGL) activity (IC50 = 315 nM), which is a serine hydrolase involved in the biological deactivation of the endocannabinoid 2-arachidonoyl-sn-glycerol (2-AG) [1-3]. Euphol exhibits diverse biological activities, such as anti-viral, anti-inflammatory, and anti-cancer effects[4].
Euphol-induced(0-125ug/ml) poptosis revealed by elevated caspase 3/7 activity, was correlated with a significant inhibition of MAP kinase/Erk 1/2 and PI3K/Akt signaling pathway in glioblastoma U87 MG cells[5]. Euphol(2- 60 µg/mL;72h) can inhibit the proliferation of gastric cancer CS12 cells. Euphol induces ERK1/2 phosphorylation in CS12 cells[6]. In T47D human breast cancer cells, treatment of cells with different doses of euphol(0.01mM-0.3mM) for 24, 48, 72 h resulted in decreased cell viability, accompanied by G1 phase cell accumulation[7].
Euphol treatment decreased cyclin D1 expression and low phosphorylation of Rb. Euphol(10 mg/kg; p.o.) attenuates the clinical signs of experimental autoimmune encephalomyelitis (EAE), It inhibited EAE induced dyskinesia [8].Mice treated with euphol (30 mg/kg；p.o.) were protected from marked body weight loss and recovered a healthy appearance that was similar to that of control healthy mice (non-colitic) [9].

真酚(Euphol)是Euphorbia tirucalli中的主要成分,真酚可逆的抑制丝氨酸水解酶MGL活性(IC50 = 315 nM)[1-3]。并且真酚具有抗病毒、抗炎、抗癌等多种生物活性[4]。
真酚(0-125ug/ml)在在胶质母细胞瘤U87 MG细胞中诱导的caspase 3/7活性升高,这与Erk 1/2和PI3K/Akt信号通路的显著抑制相关[5]。真酚(2- 60 µg/mL;72h)对CS12细胞增殖有抑制作用,真酚可以诱导CS12细胞ERK1/2磷酸化[6]。在T47D人乳腺癌细胞中,用不同剂量的真酚(0.01mM-0.3mM；24、48、72 h)处理细胞会导致细胞活力下降,细胞聚集在G1期[7]。
真酚处理降低了cyclin D1的表达,降低了Rb的磷酸化水平。真酚(10 mg/kg; p.o.)可以减轻实验性自身免疫性脑脊髓炎(EAE)的临床症状,抑制EAE诱导的运动障碍[8]。用真酚(30 mg/kg;p.o.)治疗的小鼠体重不会减轻,和健康小鼠(非结肠炎)在外观上无差距[9]。
