Product Description

Targets
Impurity of Sacubitril
ln Vitro
Sacubitril was recently approved by the Food and Drug Administration for use in combination with valsartan for the treatment of patients with heart failure with reduced ejection fraction. As a prodrug, sacubitril must be metabolized (hydrolyzed) to its active metabolite sacubitrilat (LBQ657) to exert its intended therapeutic effects. Thus, understanding the determinants of sacubitril activation will lead to the improvement of sacubitril pharmacotherapy. The objective of this study was to identify the enzyme(s) responsible for the activation of sacubitril, and determine the impact of genetic variation on sacubitril activation. First, an incubation study of sacubitril with human plasma and the S9 fractions of human liver, intestine, and kidney was conducted. Sacubitril was found to be activated by human liver S9 fractions only. Moreover, sacubitril activation was significantly inhibited by the carboxylesterase 1 (CES1) inhibitor bis-(p-nitrophenyl) phosphate in human liver S9. Further incubation studies with recombinant human CES1 and carboxylesterase 2 confirmed that sacubitril is a selective CES1 substrate. The in vitro study of cell lines transfected with wild-type CES1 and the CES1 variant G143E (rs71647871) demonstrated that G143E is a loss-of-function variant for sacubitril activation. Importantly, sacubitril activation was significantly impaired in human livers carrying the G143E variant. In conclusion, sacubitril is selectively activated by CES1 in human liver. The CES1 genetic variant G143E can significantly impair sacubitril activation. Therefore, CES1 genetic variants appear to be an important contributing factor to interindividual variability in sacubitril activation, and have the potential to serve as biomarkers to optimize sacubitril pharmacotherapy[1].

Additional Infomation
最近,美国食品药品监督管理局批准沙库比曲与缬沙坦联合用于治疗射血分数降低的心力衰竭患者。作为前药,沙库必曲必须代谢(水解)为其活性代谢产物沙库必曲特(LBQ657)才能发挥其预期的治疗作用。因此,了解sacubitril激活的决定因素将有助于sacubitri药物治疗的改进。本研究的目的是确定负责sacubitril激活的酶,并确定遗传变异对sacubitri激活的影响。首先,对sacubitril与人血浆和人肝、肠和肾的S9级分进行了孵育研究。发现只有人肝S9级分才能激活萨克比曲。此外,羧酸酯酶1(CES1)抑制剂双-(对硝基苯基)磷酸酯在人肝脏S9中显著抑制了沙库必曲的激活。用重组人CES1和羧酸酯酶2进行的进一步孵育研究证实,沙库必曲是一种选择性的CES1底物。用野生型CES1和CES1变体G143E(rs71647871)转染的细胞系的体外研究表明,G143E是sacubitril激活的功能缺失变体。重要的是,在携带G143E变体的人类肝脏中,sacubitril的激活显著受损。总之,在人类肝脏中,sacubitril被CES1选择性激活。CES1基因变体G143E可显著损害sacubitril的激活。因此,CES1基因变异似乎是导致沙库必曲激活个体间变异的重要因素,并有可能作为优化沙库必曲药疗的生物标志物[1]。

  • Enter 10 in the Concentration box and choose the correct unit (mM)
  • Enter 5 in the Volume box and choose the correct unit (mL)
  • Click the “Calculate” button
  • The answer of 17.513 mg appears in the Mass box. In a similar way, you may calculate the volume and concentration.

Dilution Calculator allows you to calculate how to dilute a stock solution of known concentrations. For example, you may Enter C1, C2 & V2 to calculate V1, as detailed below:

What volume of a given 10 mM stock solution is required to make 25 ml of a 25 μM solution?
Using the equation C1V1 = C2V2, where C1=10 mM, C2=25 μM, V2=25 ml and V1 is the unknown:
  • Enter 10 into the Concentration (Start) box and choose the correct unit (mM)
  • Enter 25 into the Concentration (End) box and select the correct unit (mM)
  • Enter 25 into the Volume (End) box and choose the correct unit (mL)
  • Click the “Calculate” button
  • The answer of 62.5 μL (0.1 ml) appears in the Volume (Start) box
