生物活性

Cynarin (Cynarine) 是一种来自artichoke洋蓟的植物化学成分，具有多种药理特性，包括自由基清除、抗氧化剂、抗组氨酸和抗病毒活性。Cynarin 可阻断T细胞受体的 CD28 和抗原呈递细胞的 CD80 之间的相互作用。Cynarin 可触发 Nrf2 的核易位，恢复 glutathione (GSH) 和 reactive oxygen species (ROS) 的平衡，并抑制线粒体去极化。

体外研究

Cynarin inhibits taste receptors, making water to be sweet. It has been shown to have some pharmacological properties including hypocholesterolemic, hepatoprotective, antiviral, antibacterial, and antihistamic effects. Cynarin has marked antioxidant, anticholinergic, reducing ability, radical-scavenging, and metal-binding activities. Cynarin demonstrates 87.72% inhibition of linoleic acid lipid peroxidation at 30 mg/mL concentration. Cynarin exhibits effective DMPD + , ABTS + , O 2 - , DPPH 1 , and H 2 O 2 scavenging effects, reducing capabilities and Fe 2+ chelating effects. IC 50 and K i of cynarin for acetylcholinesterase enzyme inhibition are 243.67nM and 39.34±13.88 nM, respectively. Cynarin is a potential immunosuppressant that blocks the interaction between the CD28 of T-cell receptor and CD80 of antigen presenting cells. Cynarin blocks about 87% of the CD28-dependent "signal 2" pathway of T-cell activation under the condition of one to one ratio of T-cell and B-cell. Cynarin binds to the "G-pocket" of CD28 and thus interrupts the site of interaction between CD28 and CD80.
