This is a set comprising the second and third volumes in the series. They review the progress being made in CoMFA and other 3D QSAR approaches since the publication of the first volume. Volume Two, "Ligand-Protein Interactions and Molecular Similarity", is divided into three sections dealing with: ligand-protein interactions, quantum chemical models and molecular dynamics simulations; and pharmacophore modelling and molecular similarity, respectively. Volume Three, "Recent Advances" is also divided into three sections, namely: 3D QSAR methodology - CoMFA and related approaches; receptor models and other 3D QSAR approaches; and 3D QSAR applications. More than 70 scientists have contributed nearly 40 reviews of their work and related research to these two volumes. The works present an up-to-date coverage of the latest developments in all fields of 3D QSAR.
