High-Throughput Screening for Drug Discovery toward Infectious Diseases: Options and Challenges

Abstract

The increase in the number of antibiotic-resistant microbial strains makes it evident to discover and develop newer efficacious anti-infective drugs. High-throughput screening (HTS) is a robust technology that plays a crucial role in identifying novel anti-infective lead compounds. This chapter briefly explains the role of virtual HTS (vHTS) and HTS technologies in lead identification using various categories of chemical libraries through structure-based drug design, ligand-based drug design, in vitro cell-based assay, and biochemical assay approaches involved in the process of drug design and discovery. The chapter also gives an insightful survey of the technologies such as fluorescence, luminescence, and atomic absorbance used for the detection of biological responses in the HTS bioassays. Applications of HTS, reverse pharmacology, current challenges, and future perspectives of HTS in the pharmaceutical and biotechnology industry are discussed in the context of anti-infective drug design, discovery, and development.
