More than 20 years of experience in molecular structure generation, from conceptualization through to applications Innovative, interdisciplinary text demonstrating example queries with software packages such as MOLGEN-online Detailed explanations on establishing QSPRs and QSARs as well as structure elucidation using mass spectrometry and structure generation. Aims and Scope This work provides an introduction to mathematical modeling of molecules and the resulting applications (structure generation, structure elucidation, QSAR/QSPR etc.). Most chemists have experimented with some software that represents molecules in an electronic form, and such models and applications are of increasing interest in diverse and growing fields such as drug discovery, environmental science and metabolomics. Furthermore, structure generation remains the only way to systematically create molecules that are not (yet) present in a database. This book starts with the mathematical theory behind representing molecules, explaining chemical concepts in mathematical terms and providing exercises that can be completed online. The later chapters cover applications of the theory, with detailed explanations on QSPR and QSAR investigations and finally structure elucidation combining mass spectrometry and structure generation. This book is aimed in particular at the users of structure generation methods and corresponding techniques, but also for those interested in teaching and learning mathematical chemistry, and for software designers in chemoinformatics.

The search for bioactive secondary metabolites from marine organisms has been an active area of research since the 1950s. The distinct biodiversity of the marine environment has afforded a vast array of unique secondary metabolites, many of which possess potent biological activities. This Special Issue of Marine Drugs will highlight recent bioactive marine natural product studies conducted by southern hemisphere scientists on an array of marine organisms.

Sulfur is an essential element for all living organisms and is required by algae, plants, fungi, animals, and humans for growth and development. It is present in a variety of biomolecules involved in many biological functions, including the maintenance of cell redox homeostasis, defense, and detoxifying processes. The alteration of sulfur compound metabolism may lead to human diseases as well as to plant and animal pathologies. The marine environment, which is characterized by a high biodiversity of species and a great chemical diversity, represents a great potential source of bioactive sulfur molecules. A broad range of biologically active sulfur compounds with unique structures and pharmacological properties have been reported to occur in marine organisms, from amino acids to different sulfated derivatives. Great attention is also focused on sulfur metabolites in the marine microbial world in relation to the global sulfur cycle. The aim of this Special Issue is to present existing knowledge and recent studies on sulfur-containing marine bioactive compounds in different biological systems. Attention is also focused on metabolites active at the ecological level.
