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