Data Sheet 产品使用指南

Vincamine 是从马达加斯加长春花中提取的一种单萜类吲哚生物碱。Vincamine 可以作为一种外周血管扩张剂 (Vasodilator)，对脑微血管循环有选择性的血管调节作用。Vincamine 是一种 GPR40 激动剂，通过改善 β 细胞功能障碍和促进葡萄糖刺激型胰岛素分泌 (GSIS) 发挥 β 细胞保护作用。Vincamine 可改善体内葡萄糖稳态，对 2 型糖尿病 (T2DM) 的研究具有潜力。

生物活性

Vincamine is a monoterpenoid indole alkaloid extracted from the Madagascar periwinkle. Vincamine is a peripheral vasodilator and exerts a selective vasoregulator action on the brain microcapilar circulation. Vincamine is a GPR40 agonist and acts as a β-cell protector by ameliorating β-cell dysfunction and promoting glucose-stimulated insulin secretion (GSIS). Vincamine improves glucose homeostasis in vivo, and has the potential for the type 2 diabetes mellitus (T2DM) research.

体外研究

Vincamine (20, 40 and 80 μM; 24 hours) exerts a signiﬁcant, concentration-dependent protective effect in LPS-treated human corneal epithelial cells (HCECs) cells.
Vincamine (20, 40 and 80 μM; 24 hours) significantly reduces ROS level in a dose-dependent manner in LPS-treated human corneal epithelial cells (HCECs)cells. Additionally, after Vincamine administration, the levels of MDA is also significantly reduced while the levels of T-AOC, and SOD are increased in a dose-dependent manner.
Vincamine (20, 40 and 80 μM; 24 hours) rescues TrxR activity in a dose-dependent manner in HCECs. However, the intracellular activities of Trx, GR and GPx are neither inhibited nor activated by both LPS and Vincaminer.
Vincamine could activate GPR40 (EC₅₀=6.28 µM) with DHA (GPR40 ligand) as a positive control (EC₅₀=3.85 µM) in hGPR40-CHO cells.

体内研究

Vincamine (intraperitoneal injection; 15 and 30 mg/kg/day; 6 weeks) improves glucose tolerance in type 2 diabetic model mice. It effectively lowers the levels of fasting blood glucose and glycated hemoglobin. At the same time, it ameliorates oral glucose tolerance and elevated glucose-induced plasma insulin concentration without influence on basal insulin secretion in vivo.<.br>

Animal Model:	Male and female db/db mice (BKS.Cg-DockLepr/J) and HFD/STZ-induced type 2 diabetic model mice
Dosage:	15 and 30 mg/kg/day
Administration:	Intraperitoneal injection; 15 and 30 mg/kg/day; 6 weeks
Result:	Enhanced glucose tolerance in HFD/STZ and db/db male mice.
