Evaluation of the protective effect of salvianolic acid A on ischemic heart failure by a multi-target pharmacokinetic-pharmacodynamic model

  • 摘要: 基于代谢平衡模型,建立多靶点药代动力学-药效学(PK-PD)结合模型,从整体角度评价丹酚酸A(Sal A)对缺血性心衰的保护作用。大鼠随机分为3组,分别为假手术组、缺血性心衰组和Sal A给药组,结扎后立即给药,连续给药4周,分别于给药前和给药后1、2、3、4周采集血样,测定血浆中脑钠肽(BNP)、血管紧张素Ⅱ(AngⅡ)、丙二醛(MDA)、不对称二甲基精氨酸(ADMA)含量以及谷胱甘肽过氧化物酶(GSH-Px)酶活力,基于上述标志物建立代谢平衡模型,选用代谢失衡动力学参数k从整体角度量化机体状态,并以参数k的变化率作为替代药效指标建立多靶点PK-PD模型,用以考察Sal A对缺血性心衰的保护作用。结果显示,Sal A对各标志物均有一定的改善作用,参数k与表征心功能的指标左心室射血分数相关性良好,模型可以很好地拟合Sal A的血浆药物浓度-曲线下面积(AUC)和药物对参数k的改善程度I之间的关系。基于代谢平衡模型建立的多靶点PK-PD模型能够很好地评估Sal A对缺血性心衰的保护作用,为多靶点中药PK-PD模型的建立提供了新的思路。
    Abstract: The aim of this study was to develop a multi-target pharmacokinetic-pharmacodynamic(PK-PD)model for the evaluation of the protective effect of salvianolic acid A(Sal A)on ischemic heart failure based on a metabolic balance model. The rats were assigned to 3 groups: sham-operated group(saline), ischemic heart failure group(saline)and Sal A-treated group(Sal A, 1 mg/(kg ·d), ip). The concentrations of brain natriuretic peptide(BNP), angiotensin II(Ang II), malondialdehyde(MDA), asymmetric dimethylarginine(ADMA)and the activity of glutathione peroxidase(GSH-Px)in rat plasma were determined before and at 1, 2, 3, and 4 weeks after ligation in all the groups. A multi-target PK-PD model was developed based on the change rate of metabolic disruption parameter k and was eventually used to integrally evaluate the protective effect of Sal A on ischemic heart failure. Sal A showed improvement effects on multiple biomarkers and the correlation study demonstrated a good relationship between dynamic parameter k and left ventricular ejection fraction(LVEF). More importantly, the multi-target model well fitted the relationship between AUC and the change rate. The multi-target PK-PD model provides a novel method to integrally evaluate the protective effect of Sal A, which might offer a new strategy for the establishment of a PK-PD model that embodies the characteristics of traditional Chinese medicine.
