This book is devoted to the secondary metabolites found in marine invertebrates of the phylum mollusca. It provides comprehensive coverage of the literature on molluscs since 1976. Compounds are grouped in chemical classes (terpenes, sterols, polypeptides, etc.) and the structure, source bioactivity and relevant references are given for each entry. There are three indexes based on trivial names, molecular formulae and natural sources. The Handbook is an essential reference work for natural products chemists and pharmaceutical researchers interested in marine metabolites.
