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。 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.
