Isolation and Structure Elucidation of Bioactive Secondary Metabolites from Microbial Sources by Kate J. Graham Pdf

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.

Special Issue in Honor of Professor James D. McChesney on the Occasion of His 80th Birthday by Muhammad Ilias,Dhammika Nanayakkara Pdf

Plants have been the sources of important pharmaceuticals, flavoring agents, and agrochemicals. The antimalarial drugs artemisinin and quinine; the anticancer drugs taxol, etoposide, and vinca alkaloids; the sugar-free sweetening agents stevioside and rebaudiosides; and antifeedant azadiractin are good examples of important plant-based drugs, food additives, and agrochemicals currently on the market. Despite these and many other successes, there are significant challenges to discovering and developing commercially important natural products from plants, such as procuring plant materials in large quantities, separating active constituents from complex mixtures, and undesirable qualities, such as low solubility or poor chemical or metabolic stability of active constituents. Dr. James D. McChesney has contributed immensely to overcoming the inherent challenges associated with discovering and developing products modeled from plant-based natural product leads. His research on artemisinin, taxol, galanthamine, podophyllotoxin, and stevia sweet glycosides exemplifies the magnitude of these contributions. His extensive work on the structural modification of taxol led to the discovery and development of the anticancer agent TPI 287, a third-generation taxane analog that is currently undergoing clinical trials. Dr. McChesney has had a long, distinguished teaching and research career, has authored more than 225 research publications, and holds more than 60 patents. He is a past president and Fellow of the American Society of Pharmacognosy and a Fellow of the AAAS. He has mentored many graduate students, post-docs, and junior faculty members who hold prominent positions in natural products research establishments in the US and worldwide. We wish to dedicate this Special Issue Book Version to celebrate the eightieth birthday of Dr. McChesney, a prolific thinker with abundant inventiveness in the field of natural product chemistry and pharmacognosy.

Phytochemistry of Medicinal Plants by John T. Arnason,Rachel Mata,John T. Romeo Pdf

Phytochemicals from medicinal plants are receiving ever greater attention in the scientific literature, in medicine, and in the world economy in general. For example, the global value of plant-derived pharmaceuticals will reach $500 billion in the year 2000 in the OECD countries. In the developing countries, over-the-counter remedies and "ethical phytomedicines," which are standardized toxicologically and clinically defined crude drugs, are seen as a promising low cost alternatives in primary health care. The field also has benefited greatly in recent years from the interaction of the study of traditional ethnobotanical knowledge and the application of modem phytochemical analysis and biological activity studies to medicinal plants. The papers on this topic assembled in the present volume were presented at the annual meeting of the Phytochemical Society of North America, held in Mexico City, August 15-19, 1994. This meeting location was chosen at the time of entry of Mexico into the North American Free Trade Agreement as another way to celebrate the closer ties between Mexico, the United States, and Canada. The meeting site was the historic Calinda Geneve Hotel in Mexico City, a most appropriate site to host a group of phytochemists, since it was the address of Russel Marker. Marker lived at the hotel, and his famous papers on steroidal saponins from Dioscorea composita, which launched the birth control pill, bear the address of the hotel.
