Description Notoginsenoside R1 (Sanchinoside R1) belongs to the saponin class of natural products, and is the main active monomer of Panax ginseng. Notoginsenoside R1 has cardiovascular, neuroprotective, hepatoprotective, antitumor and immunomodulatory activities.
In vitro 方法:人结直肠癌细胞 HCT-116 用 Notoginsenoside R1 (75-300 µM) 处理 48 h,使用 MTT assay 检测细胞活力。结果:用 75-300 µM Notoginsenoside R1 处理后的 HCT-116 细胞活力与对照组没有显著差异。然而,与对照细胞相比,用 500 µM Notoginsenoside R1 处理 48 h 的细胞活力显著降低 (58±7.26%)。[1]方法:人冠状动脉平滑肌细胞 hCASMC 用 Notoginsenoside R1 (10 µM) 处理 24 h,用 10% FBS 刺激 0-30 min,使用 Western Blot 检测靶点蛋白表达水平。结果:Notoginsenoside R1 处理后 hCASMCs 中 Akt 磷酸化以时间和剂量依赖的方式快速降低,但未观察到对 ERK1/2 和 JNK 信号传导的影响。Notoginsenoside R1 引起 p38 MAPK 磷酸化的适度降低,但这没有达到显著性。[2]
In vivo 方法:为研究对新生内膜增生的影响,将 Notoginsenoside R1 (10 mg/kg) 腹腔注射给 C57BL/6 J 小鼠,每天一次,持续三周。随后进行了小鼠股动脉损伤模型。结果:Notoginsenoside R1 在体内减轻股动脉损伤后新生内膜的形成。Notoginsenoside R1 治疗通过抑制 VSMC 增殖来减少新生内膜的形成。[2]
