Tanshinone IIA (T), salvianolic acid B (S) and ginsenoside Rb1 (G) are the three major active ingredients of Compound Danshen Formula (CDF) for its protective effects on myocardial ischemia (MI). In this study, we aimed to investigate therapeutic and synergistic effects of TSG (combination of T, S and G) on MI rats with metabolomic strategy.
MI model were induced in Sprague-Dawley rats by left anterior descending coronary artery ligation. MI rats were respectively administrated T, S, G, TSG and CDF. Plasma was analyzed by ultra-performance liquid chromatography/quadrupole time-of-flight mass spectrometry (UPLC-Q-TOF-MS). Partial least squares discriminate analysis (PLS-DA) models were built to evaluate the therapeutic and synergistic effects of TSG at whole level. 22 MI biomarkers in rat plasma were also investigated to explain that.
TSG brings nearly equal therapeutic effects on MI as CDF and it plays more stable regulated action on those 22 identified metabolites than single compound.
Overall, there were few methods for the study of synergistic effects of Chinese medicine. Our results suggested that metabolomics offers a new idea for Chinese medicine research.
丹参酮 IIA(T)、丹酚酸 B(S)和人参皂苷 Rb1(G)是复方丹参方(CDF)发挥心肌缺血(MI)保护作用的三种主要活性成分。本研究旨在采用代谢组学策略探讨 TSG(T、S 和 G 的组合)对 MI 大鼠的治疗和协同作用。
通过结扎左前降支冠状动脉诱导 Sprague-Dawley 大鼠 MI 模型。MI 大鼠分别给予 T、S、G、TSG 和 CDF 治疗。采用超高效液相色谱/四极杆飞行时间质谱联用(UPLC-Q-TOF-MS)分析血浆。建立偏最小二乘判别分析(PLS-DA)模型,以评估 TSG 在整体水平上的治疗和协同作用。还研究了大鼠血浆中的 22 个 MI 生物标志物,以解释其作用机制。
TSG 对 MI 的治疗效果与 CDF 几乎相当,与单一组分相比,它对 22 种已鉴定代谢物的调节作用更稳定。
总体而言,研究中药协同作用的方法较少。我们的结果表明,代谢组学为中药研究提供了新的思路。
