AI for Drug Discovery and Molecular Design: Using Artificial Intelligence from Target Identification to Lead Optimization

Description: Artificial intelligence can propose millions of novel molecules in minutes. Yet the rate of new drug approvals has not dramatically accelerated. Why? Because computational predictions without rigorous validation and domain expertise produce hypotheses, not drugs. The gap between a promising docking score and a clinical candidate remains wide—and bridging it requires more than faster algorithms. AI for Drug Discovery and Molecular Design: Using Artificial Intelligence from Target Identification to Lead Optimization is the first book to map AI methods directly onto the drug discovery pipeline with a relentless focus on validation and practical decision-making. Organized into six parts and 24 chapters, it walks you from foundational concepts—pipeline stages, data sources, and responsible AI—through molecular and protein representations, predictive models, structure-based screening, generative design, and finally integrated workflows for hit discovery and lead optimization. This is not a coding tutorial or a math textbook. It is a conceptual guide for scientists who need to understand what AI can and cannot do, how to choose the right representation for a given task, and how to critically evaluate predictions before committing experimental resources. Every chapter ends with a validation takeaway and explicit discussion of limitations, ensuring that you never mistake a model output for proven fact. Key areas covered: • Understand how molecules and proteins are encoded—SMILES, graphs, fingerprints, embeddings, 3D conformers—and why these choices determine what AI can learn. • Master predictive models for QSAR, ADMET, and activity, always within their applicability domain and with awareness of data bias. • Apply structure-based methods like docking, virtual screening, and protein structure prediction (AlphaFold, ESM) to generate testable binding hypotheses. • Leverage generative AI for de novo design and lead optimization, balancing potency, ADMET, and synthetic feasibility through multi-parameter optimization. • Build integrated workflows that combine similarity, docking, QSAR, and ADMET filters to prioritize compounds for experimental follow-up. Written for pharmaceutical researchers, medicinal chemists, and R&D professionals with an intermediate background in drug discovery, this book requires no coding or advanced math. It speaks the language of medicinal chemistry and biological assays, making complex AI concepts accessible through clear explanations and real-world scenarios. If you are tired of overblown claims and want a practical, honest guide to what AI can and cannot do in drug discovery, this book delivers. It will change how you approach computational screening, property prediction, and molecular design—helping you make faster, better-informed decisions while never losing sight of the ultimate goal: bringing safe and effective therapies to patients.

AI summary: This book provides a structured introduction to AI applications across the drug discovery pipeline, covering molecular and protein representation, predictive models (QSAR, ADMET, activity), structure-based methods (docking, virtual screening, protein structure prediction), generative molecular design, and integrated workflows for hit discovery and lead optimization. It emphasizes validation, domain expertise, and responsible use, making it suitable for pharmaceutical researchers and medicinal chemists. The book avoids hype and focuses on practical decision-making supported by examples and workflow diagrams.
