描述 |
Astramembrangenin 环黄芪醇是一种三萜皂苷化合物,是黄芪 (Astragalus membranaceus (Fisch.) Bunge) 中活性成分的水解产物。Astramembrangenin 具有口服安全性,具有广泛的药理学作用,包括端粒酶活化,端粒延长,抗炎和抗氧化特性。Astramembrangenin 具有抗衰老特性,CAG 刺激人新生角质形成细胞和大鼠神经细胞中的端粒酶活性,并诱导 CREB 活化。 Astramembrangenin 可能在抑郁症中具有新的治疗作用。 |

与HEK培养物中的载体对照相比,星形膜蛋白(0-10μM; 3-6天)增加细胞生长[1]。Astramembrangenin(0.3μM; 5-90分钟)在原代皮质神经元中诱导CREB磷酸化,两种细胞类型中总CREB表达不受CAG的影响[1]。星形膜蛋白(3μM; 6-48小时)可促进神经元中的活体信号传导,增加tert mRNA表达,表现出增加的bcl2 mRNA表达[1]。细胞活力测定[1]细胞系:HEK细胞浓度:1μM,3μM,10μM培养时间:3-6天结果:6天时细胞生长倍增。Western Blot分析[1]细胞系:神经元细胞浓度:0.3μM培养时间:5分钟,15分钟,30分钟,90分钟。结果:提示CAG诱导神经元细胞CREB活化。RT-PCR[1]细胞系:神经元细胞浓度:3μM培养时间:6-48小时结果:tert,bcl2 mRNA表达增加。 |
