SMART assays for tough targets in drug discovery
High-throughput screening (HTS) is a fundamental, efficient, broadly used, and fast strategy to identify hits representing a key starting point for the development of novel drugs. The targets for HTS are selected for their disease relevance and can be specific molecular targets, but also intracellular pathways or altered phenotypic evidence. The choice of the most suitable assay format for a given target/pathway is mainly driven by the disease relevance of the assay. Apart from the disease relevance, assays suitable for HTS need to be sensitive, robust, and cost effective. The robustness of an assay can be assessed with quality parameters which include the Z’ score, pharmacological reproducibility and the signal stability over time.
In the last years, the targets identified for conducting HTS campaigns became more and more challenging, as in most cases they do not belong to the more classical druggable families, such as GPCRs, ion channels, or enzymes like kinases, but are more likely to come from a wide range of categories most often defined as undruggable.
In our webinar, we will present a collection of many different cell-based and cell-free assays we developed using different approaches and technologies, to run HTS on tough targets, including protein-protein and protein-RNA interactions, protein degradation, protein aggregation, RNA splicing modulation and inducible RNA silencing, phenotypic analysis, organellar ion channels and solute carrier proteins.
HTS-grade assays, multi-subunit enzyme, protein aggregation, protein interaction, protein degradation, RNA focused assays, splicing assays, lysosomal disease, autophagy, organellar patch clamp, phenotypic assays.
