HTS Drug Screening
HTS drug screening is a technology-driven method that leverages automation, miniaturization, and parallel processing to assess the biological activity or mechanism of numerous candidate compounds efficiently. This approach significantly enhances the early stages of drug discovery, which are traditionally constrained by lengthy and costly processes. By simultaneously evaluating thousands to millions of samples, HTS drug screening has become a cornerstone of modern drug development.
This technique is extensively applied not only to the primary screening and optimization of small molecule drugs but also to the functional assessment of biological macromolecules such as peptides, antibodies, and nucleic acid drugs. Additionally, it facilitates the experimental validation of candidate molecules from natural products, combinatorial chemical libraries, and virtual screening processes. HTS drug screening has enabled researchers to identify novel drugs with unique structures and mechanisms across various fields, including oncology, infectious diseases, neurodegenerative disorders, and autoimmune diseases.
Looking forward, advancements in understanding disease molecular mechanisms, combined with developments in omics, artificial intelligence, and automation, are expected to propel HTS drug screening towards greater intelligence and precision. The integration of multi-omics data with screening results can elucidate drug interaction networks and predict mechanisms of action. AI-driven models can inform the design and synthesis of new drug molecules, and HTS platforms can promptly verify the biological activity of these computationally designed compounds, facilitating a seamless transition from theoretical models to experimental validation.
Methodologically, HTS drug screening employs sophisticated liquid handling systems, microplate formats (such as 96, 384, and 1536 wells), automated reading devices, and data processing algorithms. These are combined with biological assays—such as enzyme activity measurements, cell viability analyses, and fluorescence or luminescence readings—to assess the impact of tens of thousands of compounds on specific targets or biological processes. The scope of target types has expanded from enzymes and receptors to encompass ion channels, nucleic acids, signaling pathways, and complex phenotypic systems, thereby broadening the application of HTS screening from basic research to preclinical development.
Compared to traditional low-throughput methods, HTS drug screening offers significant advantages in terms of time and cost efficiency, completing the assessment of hundreds of thousands of compounds within weeks and substantially reducing the development cycle. The platform's flexibility allows adaptation to various experimental models, such as in vitro protein systems, cultured cells, and organoids. Its reliance on standardized processes and data algorithms ensures reproducibility and reliability of results. When coupled with artificial intelligence and machine learning, HTS screening facilitates rapid identification and prioritization of hit compounds, and can even provide preliminary predictions of underlying mechanisms, enhancing the identification and development potential of promising candidates.
