Frontiers in Computational Chemistry presents contemporary research on molecular modeling techniques used in drug discovery and the drug development process: computer aided molecular design, drug discovery and development, lead generation, lead optimization, database management, computer and molecular graphics, and the development of new computational methods or efficient algorithms for the simulation of chemical phenomena including analyses of biological activity. The sixth volume of this series features these six different perspectives on the application of computational chemistry in rational drug design: - Computer-aided molecular design in computational chemistry - The role of ensemble conformational sampling using molecular docking and dynamics in drug discovery - Molecular dynamics applied to discover antiviral agents - Pharmacophore modeling approach in drug discovery against the tropical infectious disease malaria - Advances in computational network pharmacology for Traditional Chinese Medicine (TCM) research - Progress in electronic-structure based computational methods: from small molecules to large molecular systems of biological significance

This book is a guide for researchers, academics and experimentalists who wish to explore density functional theory (DFT) on selected molecular systems. The salient features of the book include concise and complete coverage of DFT on biologically active molecules, a basic guide to DFT for beginners followed by its computational application using a powerful Gaussian program. Subsequently, discussions on synthetic compounds, amino acids, and natural products have been offered by the authors for the benefit of the reader. The book also features an exclusive chapter on the quantum theory of atoms in molecules and is supplemented by an appendix on the Gaussian output for methane. Key Features: · basic introduction of density functional theory · practical introduction to Gaussian program · interpretation of input and output files · explanation of calculated parameters · examples of several bioactive molecules (syenthetic and natural) · correlation between theory and experiments · exploration of the hydrogen bonds · appendix covering Gaussian outputs for methane · beginner friendly text · references at the end of each chapter DFT Based Studies on Bioactive Molecules is a suitable handbook for academics, students and researchers who are learning the basic biophysics and computational chemistry of bioactive molecules with reference to DFT models.
