Based on presentations made during the 6th International Symposium on Natural Product Chemistry, this book is divided into two broad sections. Section A includes articles on synthetic routes developed to complex natural products, while Section B is a compilation of discoveries of new natural products and their pharmacological properties.There are several chapters devoted to various advances in the ongoing quest for improved anticancer agents from natural sources, be they from plants, marine organisms or microorganisms. Approaches to the development of new antimalarial agents are reviewed, as are strategies for cancer chemopreventive agents.
