Book Description
Microbial organisms often produce biologically active and chemically intriguing secondary metabolites. To isolate and characterize compounds of novel activity and structure, bioassay- guided fractionations were employed on a variety of natural products sources. Active compounds were characterized by spectroscopic analysis and X-ray diffraction methods. As a result of these studies, six projects were completed, resulting in the purification of a diverse range of compounds containing activity in a variety of assays. A coumarin and parahydroxyphenylethanol were determined to possess phytotoxic activity from fungal pathogens. Two novel C-glycosidic compounds from a bacterial plant pathogen were found to be the first low molecular weight elicitors of the hypersensitive response in plants. A verticillin of the epi-polythiodiketopiperazine class isolated from a soil fungus was discovered to be responsible for inhibition of ras farnesylation transferase. Leafcutter ants were found to be deterred by the presence of a novel sesqualterpenoid in epiphylls. Finally, inhibitors of the PDGF receptor were isolated and characterized from a lichen.

Book Description
This book consists of an introductory overview of secondary metabolites, which are classified into four main sections: microbial secondary metabolites, plant secondary metabolites, secondary metabolites through tissue culture technique, and regulation of secondary metabolite production. This book provides a comprehensive account on the secondary metabolites of microorganisms, plants, and the production of secondary metabolites through biotechnological approach like the plant tissue culture method. The regulatory mechanisms of secondary metabolite production in plants and the pharmaceutical and other applications of various secondary metabolites are also highlighted. This book is considered as necessary reading for microbiologists, biotechnologists, biochemists, pharmacologists, and botanists who are doing research in secondary metabolites. It should also be useful to MSc students, MPhil and PhD scholars, scientists, and faculty members of various science disciplines.

Book Description
The search for microorganisms useful in agriculture, agroalimentary and pharmaceu-tical industries requires the exploration also of ecological niches. Thus, within this background, the rumen (one of the four stomach parts of ruminals like the cow), is such an ecological niche, which is very rich in microorganisms and could be exploited in order to check the antagonistic capacity of the ruminal bacteria against pathogenic bacteria and fungi. This work thus fits in the biological fight in agriculture against the cryptogamic dis-eases. Indeed, the use of microorganisms to fight against phytopa...

Book Description
Awareness of the dangers of toxic components in antifouling coatings has raised interest in the potential for nontoxic alternatives. Marine organisms from bacteria to invertebrates and plants use chemicals to communicate and defend themselves. This book explores natural based antifoulants, their ecological functions, methods of characterisation and possible uses in antifouling. The text takes on the challenge of identifying such compounds, designing sustainable production and incorporating them into antifouling coatings.

Book Description
Bioactive Marine Natural Products is the first book available that covers all aspects of bioactive marine natural products. It fills the void in the literature for bioactive marine natural products. The book covers various aspects of marine natural products and it is hoped that all the major classes of bioactive compounds are included. Different classes of marine organisms and the separation and isolation techniques are discussed. The chemistry and biology of marine toxins, peptides, alkaloids, nucleosides and prostanoids are discussed in detail. Biological, toxicological and clinical evaluations are also dealt with to ensure that the book may be adopted at any stage by any practicing organic chemist or biologist, working in academia or in R and D divisions of pharmaceutical companies. Each chapter in the book includes an abstract to highlight the major points discussed in the text and concluding remarks are given. References to books, monographs, review articles and original papers are provided at the end of each chapter.

Book Description
We are very pleased to introduce the Book Version of our Special Issue in Molecules dedicated to the memory of the late Professor Dr. Charles D. Hufford. The issue has been a huge success, with 22 full-length peer-reviewed papers and a tribute by Professor Alice M.Clark. Authors, reviewers, and collaborators from many countries across the worldhave contributed to this endeavour, and we are truly grateful to all. This Special Issue isrepresentative of the broad impact that “Charlie” had on the field of bioactive naturalproducts. This Special Issue comprises papers from Professor Hufford’s former students,colleagues, and collaborators throughout the world who have utilized a wide array ofstate-of-the-art techniques to examine diverse natural sources to isolate and identify avariety of natural products with a wide spectrum of biological activities, including somenew microbial transformations and insights into bioactive molecules. Many new bioactive compounds are described and reported here for the first time. Bioactivities reportedinclude cytotoxicity, antimicrobial activity, anti-inflammatory activity, antileishmanialactivity, antitrypanosomal activity, antimalarial activity, analgesic activity, and beneficialliver activities, just to name a few. This Special Issue will undoubtedly have a lasting impact on the field of bioactive natural products, as exemplified by the career of Dr. Hufford. Lastly, without the timely and outstanding contributions from all of you, this Special Issue would not have been possible. We thank you all very much for your contributions and your time devoted to this Special Issue in memory of a special person. Finally, we express ourgratitude and thanks to the journal Molecules and their excellent team of expert reviewers for giving us the support and opportunity to make this Special Issue a huge success!
