Описание:

Indole Alkaloids: Spirooxindole details the multistep synthesis of natural products using schematic diagrams, providing a quick-and-easy way to review and understand new and novel synthetic strategies to construct structural frameworks of natural products. As a volume in the Visual Guides to Natural Product Synthesis series, this book presents the schematic total syntheses of natural products containing a "spirooxindole" core structure. It covers spirooxindole molecules through visual diagrams, highlighting key steps involved in total, formal and semi-syntheses. Sections cover Brevianamide A and B, Citrinadin A and B, Coerulescine and Horsfiline, Elacomine and Isoelacomine, Gelsemine, Paraherquamide A and B, Rynchophylline, Isorynchophylline, and more.

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.

Описание: This book describes a unique class of secondary metabolites, the mono- and dimeric-naphthylisoquinoline alkaloids. They exclusively occur in lianas of the palaeotropical Ancistrocladaceae and Dioncophyllaceae plant families. Their unprecedented structures include stereogenic centers and rotationally hindered, and therefore stereogenic, axes. Extended recent investigations on six Ancistrocladus species from Asia, as reported in this contribution, shed light on their fascinating phytochemical productivity, with over 100 intriguing natural products. This high chemodiversity arises from a similarly unique biosynthesis from acetate-malonate units, following a novel polyketidic pathway to plant-derived isoquinoline alkaloids. Some of the compounds show most promising anti-parasitic activities. Additionally, strategies for the regio- and stereoselective total synthesis of the alkaloids, including the directed construction of the chiral axis, are also presented.
