生物活性:
Danshenol A, an abietane-type diterpenoid, is an aldose reductase (AR) inhibitor with an IC50 of 0.1 μM. Danshenol A can protect endothelial cells from oxidative stress by directly scavenging ROS. Danshenol A has anti-inflammatory and antitumor properties. Danshenol A can be used for atherosclerosis research.
体内研究:
Danshenol A (0.3-3mg/kg;口服;每天一次;持续 12 周) 改善 SHR 大鼠的血压、心脏损伤和心肌胶原体积,并改善心功能。Danshenol A 修复线粒体结构/功能,减轻心肌氧化应激。Animal Model:Forty male spontaneously hypertensive rats (SHR) and eight male Wistar-Kyoto (WKY) rats at the age of 16 weeks
Dosage:0.3?mg/kg, 1?mg/kg, 3?mg/kg
Administration:Orally administration; daily; for 12 weeks
Result:Ameliorated blood pressure, cardiac injury, and myocardial collagen volume and improved cardiac function.
体外研究:
Danshenol A (10?nM; pretreatment for 1?h) 单独处理显示对 ICAM-1 在 mRNA 和蛋白质水平的表达没有影响。Danshenol A 显着逆转 TNF-α 诱导的 ICAM-1 表达和随后的单核细胞粘附,以及升高的活性氧 (ROS) 生成和 NOX4 表达.Danshenol A 通过 NOX4 依赖性 IKKβ/NF-κB 通路抑制 TNF-α 诱导的 ICAM-1 表达和随后的单核细胞与内皮细胞的粘附。Danshenol A (1, 3, and 10 μM; pretreated for 35?min) 恢复血管紧张素 II 诱导的心肌细胞凋亡。此外,Danshenol A 抑制心肌细胞线粒体氧化还原信号通路。Danshenol A抑制 K562 (IC50 = 0.53 μg/mL)、T-24 (IC50 = 7.94 μg/mL)、QGY (IC50 = 4.65 μg/mL) 和 Me180 (IC50 = 6.89 μg/mL) 细胞系的活性。
