The first contribution summarizes current trends in research on medicinal plants in Mexico with emphasis on work carried out at the authors' laboratories. The most relevant phytochemical and pharmacological profiles of a selected group of plants used widely for treating major national health problems are described. The second contribution provides a detailed survey of the so far reported literature data on the capacities of selected oxyprenylated phenylpropanoids and polyketides to trigger receptors, enzymes, and other types of cellular factors for which they exhibit a high degree of affinity and therefore evoke specifice responses. And the third contribution discusses aspects of endophytic actinobacterial biology and chemistry, including biosynthesis and total synthesis of secondary metabolites produced in culture. It also presents perspectives fo the future of microbial biodiscovery, with emphasis on the seondary metabolism of endophytic actinobacteria.

In this book, chemical studies are described mainly from literature reports appearing since 2000, inclusive of investigations performed by the present authors, on the diversity in secondary metabolites of Ligularia growing in the Hengduan Mountains area of China, focusing on eremophilane sesquiterpenoids and other metabolites. More than 100 Ligularia species and their related genera in the plant family Senecioneae plants (Cremanthodium, Cacalia, Senecio, and others) grow in East Asia. For many years, researchers have studied the chemical constituents of these plants, and terpenoids, flavonoids, steroids, alkaloids, and aromatic compounds have been isolated. Among these, in particular, numerous sesquiterpenoids were reported. Within this book terpenoids and aromatic compounds (total 1049), both previously unknown and known, are presented. Finally, genetic studies and synthesis investigations are briefly reviewed.

This volume highlights some recent developments on plants used widely as botanical dietary supplements and herbal medicines, especially in terms of knowledge of the chemical types and diverse biological activities of their constituents, as well as laboratory approaches for their quality control and taxonomic identification. In the first chapter, the biologically active secondary metabolites are described of selected botanicals that have a wide current use in the United States, with recent information provided also on their in vitro and in vivo biological activities. The second chapter constitutes an updated survey of the different chromatographic, spectroscopic, and metabolomics techniques that can be utilized for the quality control of botanical products. The penultimate chapter covers different nomenclatural systems that are of use for the taxonomic identification of source plants used in botanical products. Finally, deoxyribonucleic acid molecular barcoding techniques for the identification for plants used as dietary supplements are covered.

This volume describes several highly diverse subjects: Chapter 1 explores marine biodiscovery of the North-eastern Atlantic off the coast of Ireland as a model for best practice in research. The second chapter investigates Brazilian Chemical Ecology and examples of insect-plant communication studies that are mediated by natural products demonstrate the beautiful interconnectedness of species in a biome. Our third chapter comprises the advances in the science of the sesquiterpene quinone, perezone, which in 1852 was the first natural product isolated in crystalline form in the New World. The last two chapters are from a Vietnamese group and the first of these follows the phytochemistry, pharmacology, and ethnomedical uses of the genus Xanthium, which produces interesting sulfur and nitrogen containing natural products. Finally, the genus Desmos is discussed, where an overview of its constituent natural products and their in vitro pharmacological potential is described.

The first contribution of this book gives an overview on naturally occuring cycling tetrapyrroles. The article describes the four classic tetrapyrrolic structures with their porphyrin, chlorin, bacteriochlorin and corrin skeletons and also novel, interesting structures with unusual biological activities. This review mainly focuses on the occurrence, structure and biological function as well as biosynthesis and aspects of synthesis. The second article deals with the anticancer compound taxol and its semisynthetic analog docetaxel (Taxotere). Taxol was originally isolated in the late 1960 ́s on the basis of its cytotoxity and antileukemic activity, its structure was published in 1971 in a paper that has been cited 1000 times since this publication. The review focuses primarily on the interesting and novel chemistry of taxol that has been discovered over the last eight years.

This book describes current understandings and recent progress into a varied group of natural products. In the first chapter the role that total synthesis may play in revising the structures proposed for decanolides, which are ten-membered lactones found primarily in fungi, frogs, and termites is presented. The following chapter presents the development of the intriguing plant-derived sesquiterpene lactone, thapsigargin, a potent inhibitor of the enzyme, SERCA (sarco-endoplasmic Ca2+ ATPase), which has potential as a lead compound to treat cancer. The third chapter covers the potential of various plant phenolic compounds for treating the tropical and sub-tropical infectious disease, leishmaniasis. In addition the volume presents recent advances related to the plant alkaloid, cryptolepine, which is of particular interest as a lead for the treatment of malaria, trypanosomiasis, and cancer.

This volume consists of four chapters that cover a structurally diverse range of naturally occurring compounds. Chapter 1 delves into the chemistry of pyrogallols and their oxidized products, the hydroxy-o-quinones, including their role in cycloaddition reactions in the chemical synthesis of several fungal metabolites. Chapter 2 provides an in-depth description of the constituents of agarwood essential oil and smoke samples that are used in the perfumery industry, with an emphasis on the sesquiterpenoid and chromones constituents so far known. Chapter 3 discusses the defensive chemical ecology of two North American newt species that both produce tetrodotoxin, a well-known neurotoxin that causes paralysis and death in metazoans by disrupting electrical signals in the nerves and muscles. Chapter 4 discusses the limonoids and triterpenoids from the genus Walsura of the plant family Meliaceae, of which a number of species are utilized in several southeastern Asian countries in systems of folk medicine.
