Book Description
The aim of this thesis was to improve computational methods for structure based drug design, particularly for RNA targets. For the first portion, we present a critical evaluation of various computational drug design algorithms for their ability to predict experimental binding poses and rank libraries of small molecules against protein targets. In particular, we characterize the strengths and weaknesses of the ligand sampling method for the DOCK suite of programs. In the second portion of the thesis, we apply the lessons learned from protein targets to the disruption of protein-RNA interactions critical to the life cycle of the HIV virus. As a class, RNA historically has presented a difficult computational challenge both due to its highly localized charge and flexibility. Therefore, we have extended protocols and added new protocols in existing software packages such as DOCK and AMBER to predict experimental binding poses, once again validating our results using experimental data. Finally, we apply these protocols both to develop libraries of small molecules against druggable RNA targets and to establish a fragment-based library designed to find new scaffolds for RNA.

Book Description
In much of biology, the search for understanding the relation between structure and function is now taking place at the macromolecular level. Proteins, nucleic acids, and polysaccharides are macromolecule--polymers formed from families of simpler subunits. Because of their size and complexity, the polymers are capable of both inter- and intramolecular interactions. These interactions confer upon the polymers distinctive three-dimensional shapes. These tertiary configurations, in turn, determine the function of the macromolecule. Computers have become so inextricably involved in empirical studies of three-dimensional macromolecular structure that mathematical modeling, or theory, and experimental approaches are interrelated aspects of a single enterprise.

Book Description
This book is indexed in Chemical Abstracts ServiceThe interactions of proteins with other molecules are important in many cellular activities. Investigations have been carried out to understand the recognition mechanism, identify the binding sites, analyze the the binding affinity of complexes, and study the influence of mutations on diseases. Protein interactions are also crucial in structure-based drug design.This book covers computational analysis of protein-protein, protein-nucleic acid and protein-ligand interactions and their applications. It provides up-to-date information and the latest developments from experts in the field, using illustrations to explain the key concepts and applications. This volume can serve as a single source on comparative studies of proteins interacting with proteins/DNAs/RNAs/carbohydrates and small molecules.

Book Description
Discover a new paradigm in drug discovery that greatly expands the space of addressable drug targets and potential novel drugs Existing paradigms for drug discovery have focused largely on enzymes and other proteins as drug targets. In recent years, however, different varieties of ribonucleic acids have emerged as a viable focus for target-based drug discovery, with the potential to revolutionize the strategy and approach for this essential step in the drug development process. RNA as a Drug Target: The Next Frontier for Medicinal Chemistry offers a practice-oriented introduction to developing drug-like small molecules that selectively modulate both coding and non-coding RNAs. Beginning with a description and characterization of existing druggable RNAs, the book discusses how to approach different RNA targets for drug discovery. The result is a crucial resource for targeting RNAs and creating the next generation of life-saving pharmaceuticals. RNA as a Drug Target readers will also find: A complete “toolbox” for working with RNA, from structure determination to screening and lead generation techniques A wide range of addressable targets and mechanisms, including splicing modulation, riboswitches, targeted degradation, and more Authoritative discussion of the potential of RNA-targeted small molecule therapeutics for drugging the epitranscriptome RNA as a Drug Target provides an expert introduction to a new frontier in pharmaceutical research for medicinal chemists, biochemists, molecular biologists, and members of the pharmaceutical industry.

Book Description
This book provides a comprehensive overview of modern computer-based techniques for analyzing the structure, properties and dynamics of biomolecules and biomolecular processes. It is organized in four main parts; the first one deals with methodology of molecular simulations; the second one with applications of molecular simulations; the third one introduces bioinformatics methods and the use of experimental information in molecular simulations; the last part reports on selected applications of molecular quantum mechanics. This second edition has been thoroughly revised and updated to include the latest progresses made in the respective field of research.
