描述 | (-)-Eburnamonine (Vincamone) is a vasodilator that also acts as a cerebral metabolic stimulant. Pretreatment with vincamine could reduce Aβ25-35 induced oxidative stress. Vincamine markedly inhibited cell apoptosis dose-dependently. More importantly, vincamine increased the PI3K/Akt and Bcl-2 family protein ratios on preincubation with cells for 2 h[3]. Vincamine exerted protective effects on hearing via improving neurotrophin-dependent PI3K/Akt signaling pathway in spiral ganglion neurons (SGNs)[4]. Vincamine protected HCECs (human corneal epithelial cells) from LPS induced cell viability reduction and ameliorated the inflammation. Vincamine exhibited a strong antioxidant activity, decreasing ROS levels and regulating the levels of SOD (superoxide dismutase), T-AOC (total antioxidant capacity) and MDA (malondialdehyde). Vincamine also exerted anti-inflammatory activities by decreasing IL-6, IL-8, IL-1β, TNF-α, TGF-β expression[5]. |
