Bioactive Compounds from Natural Sources, Second Edition


Book Description

The first edition of Bioactive Compounds from Natural Sources was published in a period of renewed attention to biologically active compounds of natural origin. This trend has continued and intensified—natural products are again under the spotlight, in particular for their possible pharmacological applications. Largely focusing on natural products as lead compounds in drug discovery, Bioactive Compounds from Natural Sources, Second Edition: Natural Products as Lead Compounds in Drug Discovery is actually a completely new volume containing surveys of selected recent advances in an interdisciplinary area covering chemistry of natural products, medicinal chemistry, biochemistry, and other related topics. Written by some of the most reputed scientists in the field, this second edition includes new chapters from authors who contributed to the first edition as well as many chapters compiled by new authors. Introducing the reader to strategies and methods in the search for bioactive natural products, this book covers topics including: Natural sources of bioactive compounds such as aquatic cyanobacteria, filamentous fungi, and tropical plants, The tremendous potentiality of metabolic engineering of natural products biosynthesis The contribution of emerging or developing technologies to the study of bioactive natural compounds, namely computational methods and circular dichroism The potential of natural or natural-derived compounds for specific therapeutic applications: treatment of viral diseases, regulation of hypoxia-inducible factor, antimalarials, modulation of angiogenesis, and antitumor and wound-healing activity Selected examples of natural product families and related synthetic analogues, namely polyphenols and campthotecins Compiled for researchers and Ph.D. students working in interdisciplinary fields, this book will also be appreciated by readers without a background in chemistry interested in bioactive natural products, their biological and pharmacological properties, and their possible use as chemopreventive or chemotherapeutic agents. Conversely, the biological and pharmacological data and methods are accessible by chemists.

Application of a Two-dimensional Model of Hydrodynamics and Water Quality (CE-QUAL-W2) to Cordell Hull Reservoir, Tennessee


Book Description

Although not problematic within this reservoir, unacceptably low dissolved oxygen concentrations farther downstream in the system of reservoirs in the Cumberland River Basin have caused concern. This model study was undertaken to evaluate the water quality (specifically temperature and dissolved oxygen) impacts of operational changes at individual reservoir outlet structures. The study was also designed to reveal the interactions between hydrodynamics and stratification within the reservoir. Unstable stratification is thought to be responsible for additional problems in the reservoir: absence of an anticipated substantial fishery and a less than desirable amount of contact recreation. The concept of installing submerged weirs at the mouths of two of the reservoir's embayments within an established recreational site was proposed to help alleviate these 2 problems. As Cordell Hull Lock and Dam operates as a run-of-the-river navigation project on the main-stem Cumberland River, no significant operational changes at this site are possible. The reservoir is characterized by high flows, intermittent moderate to weak thermal stratification, and a relatively shallow pool. These factors combine, as was demonstrated by the model testing results, to preclude significant control over the release quality characteristics. However, the advective nature of the reservoir presents an advantage. Any changes to the quality of incoming water of Cordell Hull Reservoir will be propagated downstream, largely intact. (EDC).
