Dual-target inhibitor screening against thrombin and factor Xa simultaneously by mass spectrometry

An accurate, rapid, and cost-effective methodology for enzyme assay is highly demanded to screen the effect of compounds on target at the molecular level. Thrombin (EC 3.4.21.5) and factor Xa (FXa, EC 3.4.21.6) have been identified as the critical targets for the development of potential drugs with anticoagulant activity. In this study, a rapid, sensitive and accurate assay based on UHPLC-MS/MS method has been developed for inhibitor screening...
