While these molecules hold significant therapeutic promise, their size and complexity pose challenges in developing orally bioavailable compounds. At Sygnature Discovery, we&rsquo;ve applied a fragment-based screening approach to identify novel VHL binders that could provide alternative starting points for developing next-generation degraders.<\/p>\n<h3>About the Study<\/h3>\n<p>Leveraging our proprietary fragment library and the Biacore 8K+ platform, we conducted high-throughput screening against the VHL-Elongin B\/C (VCB) complex to:<\/p>\n<ul>\n<li>Explore new chemical vectors beyond established ligands<\/li>\n<li>Identify fragment hits suitable for medicinal chemistry expansion<\/li>\n<li>Enhance the efficiency of early stage-PROTAC development<\/li>\n<\/ul>\n<p>Our curated library design and advanced clean-screening workflows enable rapid progression from fragment screening to hit optimization.<\/p>\n<h3>Technology Spotlight<\/h3>\n<p>The Biacore 8K+ system plays a central role in our fragment screening capabilities, offering:<\/p>\n<ul>\n<li>High-throughput screening for fragments<\/li>\n<li>Exceptional sensitivity for weak binders<\/li>\n<li>Streamlined follow-up profiling for faster decision-making<\/li>\n<\/ul>\n<p>This integrated workflow accelerates the delivery of high-quality starting points for downstream medicinal chemistry programmes.<\/p>\n","protected":false},"excerpt":{"rendered":"","protected":false},"featured_media":2929,"template":"","category":[681,755,686,743],"class_list":["post-4174","poster","type-poster","status-publish","has-post-thumbnail","hentry","category-bioscience","category-fbdd","category-modalities","category-tpd"],"acf":[],"yoast_head":"<!--
