生物活性
Urolithin C, 是鞣花酸的多酚类肠道微生物代谢产物,是胰岛素分泌 (insulin secretion) 的葡萄糖依赖性激活剂。Urolithin C 是一种 L 型 Ca2+ 通道开放剂,可增强 Ca2+ 的流入。Urolithin C 通过线粒体介导的途径诱导细胞凋亡 (apoptosis),并刺激活性氧 (ROS) 的形成。
靶点
Insulin secretion
L-type Ca 2+ channel
Reactive oxygen species (ROS)
Apoptosis
体外研究
Urolithin C (20-100 μM; 1 hour; INS-1 cells) treatment enhances glucose-induced extracellular signal-regulated kinases 1/2 (ERK1/2) activation in INS-1 β-cells.
Urolithin C significantly inhibits the proliferation of PC12 cells. Urolithin C treatment actively increases the lactate dehydrogenase (LDH) release and lipid peroxidation malondialdehyde (MDA), stimulates reactive oxygen species (ROS) formation and mitochondrial membrane depolarization, and caused calcium dyshomeostasis.
Urolithin C treatment induces apoptosis and S phase cell cycle arrest.

体内研究
The pharmacokinetics of Urolithin C (10 mg/kg; intraperitoneal administration) in male Wistar rat (140-160 g) are studied. The half-life of the terminal part is 11.3 h and the total clearance (CL/F) is 3.41 L/h/kg. The initial volume of distribution (V 1 /F) and the steady-state volume of distribution (Vss/F) are 0.831 L/kg and 55.6 L/kg, respectively.
