From haystack to needle: finding value with DNA encoded library technology at GSK†
Abstract
DNA encoded library technology (ELT) provides access to broad chemical diversity through affinity selection. As an early adopter, GlaxoSmithKline enabled the development of ELT from proof of concept to full fledged contributor to the small molecule therapeutic pipeline. Unique benefits of the GSK incubation include uptake of large numbers of building blocks and privileged scaffolds, guidance on library design, and opportunities to add value beyond lead discovery. Soluble epoxide hydrolase and RIP1 kinase represent two case studies of ELT hits that have advanced into clinical studies. ELT also shows promise as a strategy to forecast target tractability. As an emerging technology, it benefits from incubation at the interface of industry and academia.
