Dictionary of Alkaloids, 2nd Edition

without comments

By: John Buckingham, Keith H. Baggaley, Andrew D. Roberts, Laszlo F. Szabo

Book Description:

While some of the most commonly investigated — and most notorious — chemicals in the world are alkaloids, many modern medicines are also based on alkaloid structures. Chemists continue to explore new synthetic routes and alkaloid derivatives in search of drug candidates for fighting disease.

Drawn from the venerable Dictionary of Natural Products, the second edition of the Dictionary of Alkaloids categorizes all known alkaloids, presenting concise chemical, structural, and physical data. The addition of an authoritative foreword, written by Geoffrey Cordell, eminent alkaloid chemist and Editor-in-Chief of the prestigious series The Alkaloids, Chemistry and Biology, sets the scene for this fascinating subject.

The Alkaloids Chemistry and Pharmacology, Volume 04

without comments

By : R.H.F Manske, H.L. Holmes

Once I had this book borrowed from a local library. It is an extensive alphabetical list of alkaloids containing a brief chemical, physical and pharmaceutical info under each alkaloid name. (Eg. melting points of the substance and its salts, solubilities, crystallisation, angles of rotation of polarised light, effects on ingestion, occurence in nature, etc.). Anyone with an interest in plant substances will find it interesting. The copy I have seen was printed in 1947 in New York, so today it may be a little out of date.

Alkaloids: Chemical and Biological Perspectives, Volume 14

without comments

By : S.W. Pelletier

Book Description:

Volume 14 of this series presents three interesting reviews of research on alkaloids. Chapter 1, by Paul L. Schiff, Jr., is a monumental effort, presenting a selective, comprehensive tabular review of research on the bisbenzylisoquinoline alkaloids, with an analysis of the respective alkaloid types. The chapter should serve as a very useful tool for the bench research scientist who is involved in the isolation and elucidation of structures of bisbenzylisoquinoline alkaloids. Moreover, the data in these tables provides the botanical distribution and occurrence (family, genus, species) of the various classes of these alkaloids. The alkaloids are also categorized by their molecular weights and structural types.

Oxidants in Biology: a question of balance

without comments

By : Giuseppe Valacchi, Paul Davis

Book Description

Oxidants, like other aspects of life, involves tradeoffs. Oxidants, whether intentionally produced or by-products of normal metabolism can either mediate a variety of critical biological processes but when present inappropriately cause extensive damage to biological molecules ( DNA, proteins, and lipids). These effects can lead to either damage that is a major contributor to aging and degenerative diseases (or to other diseases such as cancer, cardiovascular disease, immune-system decline, brain dysfunction, and cataracts) or normal physiological function- tissue repair, defense against pathogens and cellular proliferation. On the other hand the body is equipped with a complex antioxidant/oxidant handling system which includes both enzymatic and nonenzymatic (i.e. small molecules such as flavonoids, ascorbate, tocopherol, and carotenoids) produced endogenously or derived from the diet. This book focuses on how the same molecules can have favorable or noxious effects depending on location, level and timing.

Free Radical Damage and its Control, Volume 28 (New Comprehensive Biochemistry)

without comments

By : C.A. Rice-Evans, R.H. Burdon

Book Description:

This book provides a comprehensive treatise on the chemical and biochemical consequences of damaging free radical reactions, the implications for the pathogenesis of disease and how this might be controlled endogenously and by radical scavenging drugs. Oxidative stress may be influenced by exogenous agents of oxidative stress, radiation, trauma, drug activation, oxygen excess, or by exogenous oxidative stress which is associated with many pathological states including chronic inflammatory disorders, cardiovascular disease, injury to the central nervous system, and connective tissue damage. This and many other such aspects are presented clearly and in depth.

Book Description:

Donald Armstrong updates and expands his highly praised Free Radical and Antioxidant Protocols (Humana, 1998) with a collection of new and valuable methods for evaluating the pertubations in cell function resulting from increased oxidative stress. Presented in a user-friendly, step-by-step format, these readily reproducible techniques cover both free radical-derived and antioxidant biomarkers. The methodologies demonstrated include ELISA, HPLC, infrared spectroscopy, gas chromatography-mass spectroscopy, immunoblotting, electroelution fractionation, isoelectric focusing, voltametry, and electron paramagnetic resonance imaging. Special emphasis is given to the separation of complex mixtures of plant antioxidants, soft drug design to protect from toxic oxidative metabolites, in vitro oxidation conditions, and correcting for random measurement error to improve statistical interpretation. A soon-to-be-published companion volume, Oxidants and Antioxidants: Ultrastructural and Molecular Biology Protocols (0-89603-851-3), contains state-of-the-art molecular and ultrastructural methods that expand the total number of protocols to 109 assays.
