Nicergoline,溴烟碱酸的麦角林衍生物,是一种有效,选择性和具有口服活性的α1A-肾上腺素能受体拮抗剂。Nicergoline 具有血管舒张作用。Nicergoline 可以改善阿尔茨海默症小鼠的认知功能。
生物活性 | Nicergoline, an ergoline derivative ester of bromonicotinic acid, is a potent, selective and orally active antagonist ofα1A-adrenoceptor. Nicergoline has vasodilator effects. Nicergoline also has ameliorative effects on cognitive function in mouse models of Alzheimer's disease[1][2]. |
IC50& Target | |
体外研究 (In Vitro) | Nicergoline (0.3-30 μM; 24 h) attenuates activated microglia- and astrocytes-induced neuronal cell death[3]. Nicergoline (0.3-30 μM; 48 h) suppresses the production of proinflammatory cytokines and superoxide anion by activated microglia[3].

体内研究 (In Vivo) | Nicergoline (10 mg/kg; i.v. once daily for 60 d) improves impaired neurogenesis and cognitive competence in mice with Alzheimer's disease[2]. Nicergoline (10 mg/kg; i.v. once daily for 60 d) inhibits apoptosis, inflammation and oxidative stress in hippocampal cells, and regulates the activity of hippocampal cells through the PI3K/AKT signaling pathway in mice[2].
Animal Model: | 3×Tg-AD mice (male, 28-35 g, 6 weeks) with the Alzheimer's disease[2] | Dosage: | 10 mg/kg | Administration: | I.v. once daily for 60 days | Result: | Improved neurogenesis and cognitive competence. Decreased the degree of dementia. Downregulated pathogenic Aβ-42 and -40 peptides and APP in the hippocampi. Increased Levels of the neuroprotective forkhead box protein P2 (Foxp2), Src homology 2-containing inositol phosphatase (SxIP) and end-binding proteins (EB) in the hippocampi. Exhibited marked differences in the dispersion of the pyramidal cell layer between the nicergoline-treated and control groups. |
