Description

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 signi?cant, 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 (EC50=6.28?μM) with DHA (GPR40 ligand) as a positive control (EC50=3.85?μM) in hGPR40-CHO cells[2].

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>

In Vivo:

Select the appropriate dissolution method based on your experimental animal and administration route.

For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for in vivo experiments, it is recommended to prepare freshly and use it on the same day.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

  • Protocol 1

    Add each solvent one by one:  10% DMSO    40% PEG300    5% Tween-80    45% Saline

    Solubility: ≥ 2.5 mg/mL (7.05 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.

    Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
  • Protocol 2

    Add each solvent one by one:  10% DMSO    90% Corn Oil

    Solubility: ≥ 2.5 mg/mL (7.05 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown). If the continuous dosing period exceeds half a month, please choose this protocol carefully.

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL Corn oil, and mix evenly.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
