Описание: Alkaloids - Secrets of Life: Alkaloid Chemistry, Biological Significance, Applications and Ecological Role, Second Edition provides knowledge on structural typology, biosynthesis and metabolism in relation to recent research work on alkaloids, considering an organic chemistry approach to alkaloids using biological and ecological explanation. The book approaches several questions and unresearched areas that persist in this field of research. It provides a beneficial text for academics, professionals or anyone who is interested in the fascinating subject of alkaloids. Each chapter features an abstract. Appendices, a listing of alkaloids, and plants containing alkaloids are all included, as are basic protocols of alkaloid analysis.
Описание: This book presents a detailed study of the inter- and intramolecular reactions of carbonyl compounds with 1.6-enynes using gold (I) complexes. The lundurine products developed in this work show significant in vitro cytoxicity toward B16 melanoma cells.

Описание: Investigations into Calabar beans (the dried ripe seeds of Physostigma venenosum) and their alkaloidal components compose a classical scientific journey throughout some one-and-a-half centuries and not only represent a fascinating aspect of the history of medicine but which is, moreover, still ongoing at the forefront of chemical and medical discovery. Those in particular involving its major such component, l-physostigmine, have led to an understanding of some of the fundamental mechanisms occurring in physiology, pharmacology and biochemistry and, either actually or potentially (by providing a template and thereby acting as a “lead compound”) have provided a useful treatment for a variety of neurological disorders associated with irregularities in cholinergic transmission in which augmentation of cholinergic activity has proved to be beneficial. Physostigma venenosum is distributed throughout equatorial West Africa and having a colourful history – by virtue of their former use as an ordeal poison in trials for witchcraft in the Efik society of Old Calabar – are its dried ripe seeds (Calabar beans). The major toxic compound isolated from these, l-physostigmine, which is also known as eserine and is the only alkaloid as yet also to be isolated from a microbial source (along with l-N(8)-norphysostigmine) and is the first alkaloid found to contain a 1,2,3,3a,8,8a-hexahydropyrrolo[2,3-b]indole ring system, and the first natural product found to contain a carbamyl group. It also became one of the first examples whereby the mechanism of action of a drug could be defined at the molecular level relatively simply, played a crucial role in the Nobel Prize – winning discovery of the mechanism of neurohumoral transmission, and has led to products for the treatment of a wide range of disorders associated with deficiencies in cholinergic transmission. Several other alkaloids have also been isolated from the Calabar bean. For some of these, structures have been established, syntheses effected and pharmacology investigated.
