This textbook provides a hands-on, application-driven introduction to computational chemistry, molecular modeling, and artificial intelligence (AI) methods used in modern chemical, biochemical, and pharmaceutical research. Through guided tutorials and practical exercises, students learn how to apply important software tools and machine learning approaches to solve real-world problems in molecular science and biomedical research.
A significant portion of the book focuses on molecular dynamics (MD) simulations, including system preparation using CHARMM-GUI, MD simulation execution using the AMBER software suite, and trajectory analysis for evaluating protein stability, flexibility, and intermolecular interactions. Students also gain practical experience performing MM/GBSA binding free energy calculations using MD trajectory data.
The book also introduces molecular visualization and structural analysis using ChimeraX, allowing students to understand biomolecular structures and protein–ligand interactions. It then introduces structure-based drug discovery workflows through molecular docking using AutoDock Vina and machine learning–based prediction of binding affinity and dissociation constants (KD) for protein–ligand complexes.
The book further introduces quantum chemistry concepts through hands-on tutorials using GaussView and Gaussian 16, enabling students to build molecular structures, calculate molecular properties such as bond lengths and bond angles, and perform reaction free energy calculations.
The final section expands into biomedical data science by introducing machine learning approaches to predict disease onset, demonstrating how computational chemistry and AI tools can be applied to translational biomedical challenges.
Designed for upper-level undergraduate and graduate courses, this textbook is ideal for chemistry, biochemistry, pharmaceutical sciences, computational biology, and data science programs. The tutorial-based structure makes it particularly suitable for laboratory courses, computational workshops, and interdisciplinary training programs focused on AI-enabled molecular design and drug discovery.
By integrating molecular modeling, physics-based simulation methods, quantum chemistry, and machine learning workflows, this textbook equips students with the practical computational skills required for careers in academia, biotechnology, pharmaceuticals, and data-driven molecular science.
