2 Lead-hit-based methods for drug design and ligand identification
-
Gita Chawla
Abstract
The field of drug discovery has undergone a transformative shift with the advent of lead-hit-based methods, revolutionizing the process of drug design and ligand identification. This chapter provides a comprehensive overview of these innovative methodologies and their pivotal role in modern drug development. Lead discovery entails the identification of promising compounds, or “hits,” which serve as starting points for drug design. High-throughput screening (HTS) techniques, virtual screening, fragment- based drug design (FBDD), phenotypic screening, and natural product screening are examined in depth, highlighting their distinct approaches and applications. HTS enables rapid assessment of vast compound libraries, while virtual screening employs computational algorithms to predict ligand-target interactions. Phenotypic screening explores complex cellular responses, while natural product screening delves into nature’s chemical diversity. The chapter discusses the integration of these methods with cuttingedge computational tools and artificial intelligence, enhancing the accuracy and efficiency of hit identification. By elucidating the synergy between experimental and computational approaches, this chapter underscores the transformative impact of leadhit- based methods in shaping the future of drug discovery.
