AI Article Synopsis

  • The study investigated how SR26334, a metabolite of clopidogrel bisulfate that lacks antiplatelet effects, influences gene expression in human umbilical vein endothelial cells (HUVEC).
  • It identified 235 genes with significant changes in expression after exposure to SR26334, including 176 genes that were up-regulated and 59 that were down-regulated.
  • The findings suggest that SR26334 affects various cellular processes, such as transcription regulation and cell cycle control, indicating its potential role in modulating endothelial cell functions at the gene level.

Article Abstract

This study was purposed to characterize the effect of carboxylic acid metabolite (SR26334) of clopidogrel bisulfate deprived of antiplatelet efficacy on the spectrum of gene expression in the cultured human umbilical vein endothelial cell (HUVEC) line (EA.hy926), and to explore the potential molecule mechanism of SR26334 impact on HUVEC. By using a Affymetrix HU133 plus 2.0 oligonucleotide microarray, the alteration of gene expression spectrum induced by SR26334 in HUVEC was detected, the real-time PCR was used to confirm the results of selected differentially expressing genes. The results indicated that total 235 including 176 up-regulated and 59 down-regulated genes were obtained with change more than 1.5-fold after SR26334 (10 µmol/L) acted on HUVEC for 48 h. SR26334 affected the expression levels of genes involved regulation of transcription, transcription, positive regulation of transcription from RNA polymerase II promoter, cell cycle, cell division, protein amino acid dephosphorylation in HUVEC. It is concluded that carboxylic acid metabolite SR26334 of clopidogrel bisulfate modulates function of endothelial cells through different pathway at gene level.

A sensitive and specific high-performance liquid chromatography-tandem mass spectrometry method has been developed to determine the pharmacokinetic interactions of the antiplatelet agents aspirin and clopidogrel combined with dl-3-n-butylphthalide. For the determination of aspirin metabolite salicylic acid, clopidogrel inactive metabolite SR26334 and NBP prototype drug in rat plasma, plasma samples were prepared by precipitation of proteins using methanol containing 0.1% formic acid, followed by centrifugation.

Introduction: Simultaneous administration of acetylsalicylic acid (ASA) and clopidogrel has demonstrated efficacy in the treatment of acute coronary syndrome. Clopidogrel + ASA in a fixed-dose combination (FDC) provides a pharmaceutical option to enhance adherence to the coadministration of dual antiplatelet therapy (DAPT). Herein, we evaluate the bioequivalence of enteric ASA and clopidogrel in an FDC compared with simultaneous administration of the individual formulations.

Introduction: Dual antiplatelet therapy, aspirin and a P2Y inhibitor, is recommended to prevent thrombotic complications of acute coronary syndrome. Clopidogrel plus acetylsalicylic acid combination is the most commonly used dual antiplatelet therapy recommended by international guidelines and in Chinese clinical practice. Poor adherence to dual antiplatelet therapy or premature interruption of dual antiplatelet therapy is an important contributor to cardiovascular mortality and lethal cardiovascular events.

The major metabolic pathway of clopidogrel is conversion to carboxylic acid by an esterase (CES1), forming clopidogrelic acid (SR26334) that is inactive. There is agreement on the structure of the active metabolite; however, there are differing views about the mechanism of its formation. Sanofi studied the conversion of clopidogrel to the active metabolite using human liver microsomes.

What Is Known And Objective: Variation of the cytochrome P450 2C19 gene coding for the CYP2C19 enzyme has been reported to be associated with clopidogrel response variability. The activity of the CYP2C19 enzyme is genetically influenced by polymorphisms of its gene.

Methods: This study was conducted to assess the impact of CYP2C19 polymorphism on the clopidogrel metabolism, indirectly selecting the plasma concentration ratios of clopidogrel to its inactive metabolite SR26334 as an evaluation index.
