Reliable high-throughput functional screening with 3-FABS

Abstract

An NMR method called 3-FABS has extended the capabilities of NMR, enabling rapid, efficient and reliable high-throughput functional screening for the identification of inhibitors and for measuring their 50% mean inhibition concentration (IC(50)) with accuracy. The substrate is tagged with a CF(3) moiety and (19)F NMR spectroscopy is used for the detection of the substrate and product components. We provide comprehensive insight into 3-FABS, a discussion of its strength and weakness when compared with other HTS techniques and a presentation of some of its applications to the screening of different enzymes and to multiple screening.
