Summary
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 [1] . 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 [2] .
In Vitro
Vincamine (20, 40 and 80 μM; 24 hours) exerts a significant, concentration-dependent protective effect in LPS-treated human corneal epithelial cells (HCECs) cells
[1]
.
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
[1]
.
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
[1]
.
Vincamine could activate GPR40 (EC
50
=6.28 µM) with DHA (GPR40 ligand) as a positive control (EC
50
=3.85 µM) in hGPR40-CHO cells
[2]

MCE has not independently confirmed the accuracy of these methods. They are for reference only.
In Vivo
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 [2] .<.br>
