The Alkaloids
The Alkaloids: Chemistry and Physiology, Volume IX focuses on alkaloid chemistry. This book discusses the occurence of known aporphines in plants, reductions with sodium in liquid ammonia, alkaloids related to corydaline, and quaternary alkaloids containing an N-methyl group. The phthalideisoquinoline alkaloids, alkaloids containing one diphenyl ether linkage, trisisobutylisoquinoline alkaloids, and alkaloids of Platydesma campanulata are also elaborated. This publication likewise covers the stereochemistry of the ring nitrogen in the tropanes, pharmacologically active synthetic tropanium salts, and alkaloids of apocynaceae. Other topics include the isolation and purification of salamandra alkaloids, biological activity of tylophora alkaloids, and structure of himbosine. This volume is valuable to chemists and researchers interested in alkaloids and their structures.

The Alkaloids
Provides coverage of this field. Each volume provides detailed coverage of particular classes or sources of alkaloids.
Intracellular pH and its Measurement
This volume introduces a summary of all the techniques used to estimate pH reliably. Emphasis is placed on the techniques that provide the most reliable and detailed data. The role of cell pH is explained with special emphasis on enzymology and membrane transport and bioenergetics. This book was written especially for molecular biologists, biochemists and biophysicists.
Near-Infrared Dyes for High Technology Applications
This book summarizes the results of the NATO Advanced Research Workshop on "Syntheses, Optical Properties, and Applications of Near-Infrared (NIR) Dyes in High Technology Fields" held at Trest (Czech Republic) from September 24 to 27, 1997. It was attended by 52 scientists from 16 countries, among them 18 participants from 8 Eastern-Europe. The Workshop has been stimulated by the great progress that has been made in utilizing NIR dyes in high technology areas. This has been triggered by the availability of reliable. vel)' small, and inexpensive laser diodes emitting in the NIR region which raise the analytical detection limits by several orders of magnitude, allow time-resolved measurements for temporal discrimination between spectrally similar species, and make possible miniaturization as well as remote sensing through space and by fiber optical techniques. Furthermore, NIR dyes proved to be vel)' important in other high technology fields such as laser physics, optical recording techniques, nonlinear optics, biochemistty and medicine.

Studies in Natural Products Chemistry
Natural products play an integral and ongoing role in promoting numerous aspects of scientific advancement, and many aspects of basic research programs are intimately related to natural products. The significance, therefore, of the 28th volume in the Studies in Natural Product Chemistry series, edited by Professor Atta-ur-Rahman, cannot be overestimated.This volume, in accordance with previous volumes, presents us with cutting-edge contributions of great importance. The first paper presents over 100 compounds obtained from Broussonetia spp., and discusses biological activities. This is followed by similar contributions dealing with the genus Licania and Ginkgo biloba. Additional papers describe in detail a number of interesting and important natural compounds or structural classes: retinoids, tetramic acid metabolites, isoprenylated flavonoids, plant polyphenols, crocin, marcfortine and paraherquamide, acaricides, podolactones, triterpene glycosides and sulfur-containing marine compounds. An additional paper focuses on the antitumor activities of lipids, and a final contribution deals with natural product amelioration of cancer chemotherapy-induced adverse reactions.
Natural Poisons and Venoms
Biogenic toxins are fascinating natural products characterized by an enormous diversity of chemical structures and pharmacological activities. They not only pose hazards to humans and animals, but they are important components in the interplay of substances and living beings in nature and, moreover, important sources for new drugs. Numerous images of plants and chemical structural formulas complete the book, as well as extensive references for further reading. The multivolume reference is an essential resource for physicians, veterinarians, pharmacists, chemists, biochemists, food chemists and biologists, for students in the relevant fields, and maybe for interested laymen. All aspects of na...
