Carvacrol is a monoterpene phenol with oral activity[1]. Carvacrol has antioxidant, antibacterial, antifungal, anticancer, anti-inflammatory, hepatoprotective, antispasmodic, and vasodilatory properties[2]. Carvacrol is usually used in research related to cancer and inflammation[3]. Carvacrol is also used as a flavoring agent and preservative in food at low concentrations, as well as a fragrance component in cosmetic formulas[4].
In vitro, treatment of MCF-7 breast cancer cells with Carvacrol (0-250µM; 24 or 48h) significantly reduced cell viability, induced cell cycle arrest at the G0/G1 phase, and promoted cell apoptosis[5].
In vivo, Carvacrol (20-80mg/kg/day; p.o.; 6 days) significantly reduced the levels of pro-inflammatory cytokines TNF-α and IL-6, malondialdehyde (MDA), nitric oxide (NO), and arginase activity in a rat sepsis model induced by LPS in a dose-dependent manner[6]. Carvacrol (30mg/kg/day; intraperitoneal injection from postoperative day 1 to day 9) significantly prolonged graft survival, reduced inflammatory cell infiltration in skin allografts, and decreased the expression of pro-inflammatory cytokines such as IL-6, TNF-α, and IL-17 in a mice skin allograft model[7].

Carvacrol 是一种具有口服活性的单萜酚[1]。Carvacrol具有抗氧化、抗菌、抗真菌、抗癌、抗炎、保肝、解痉和血管松弛剂特性[2]。Carvacrol通常用于癌症、炎症等相关研究[3]。Carvacrol 也被用作低浓度的食品调味成分和防腐剂,以及化妆品配方中的香味成分[4]。
体外实验中,用Carvacrol处理MCF-7乳腺癌细胞(0-250µM;24或48小时)显著降低细胞活性,诱导细胞周期停滞在G0/G1期,并促进细胞凋亡[5]。
体内实验中,Carvacrol(20-80mg/kg/天;口服;6天)剂量依赖性地降低了由LPS诱导的大鼠脓毒症模型中促炎细胞因子TNF-α和IL-6、丙二醛(MDA)、一氧化氮(NO)以及精氨酸酶活性的水平[6]。Carvacrol(30mg/kg/天;从术后第1天起至第9天进行腹腔注射)显著延长了皮肤异种移植模型小鼠的移植皮肤存活时间,减少了移植皮肤中的炎症细胞浸润,并降低了促炎细胞因子(如IL-6、TNF-α和IL-17)的表达[7]。
