Natural Products Updates (provided by the Royal Society of Chemistry) is a literature update service keeping you current on recent developments in natural products chemistry. It contains a wide range of primary sources from general and organic chemistry covering the isolation of new natural compounds, biosynthesis, structure determination, and studies of biological activities. The records contain complete bibliographic data on original articles, the structure of treated compounds, and links to the original publication by publisher. The service allows for searching by topic, parent organism, biological activity, or structure type as well as searching contents by classification according to parent organisms, compound classes, or biological activity. Users can create their own personal profiles to save their search results and set up notifications of new contents, save compound structures, and export selected records to bibliography management tools.
