The Analyst, 1937
The article on ergot in this Handbook (vol. II, 2, pp. 1297–1354) was written by Arthur Cushny in 1914 but not published until 1924, without further revision. Thus a gap of more than two decades has now to be filled. In this interval the number of known ergot alkaloids has increased from two to eleven or twelve, all crystalline, and a considerable ...

Pituitary Hormones and Ergot Alkaloids
Pharmacology, 2008From the data presented it appears that ergot drugs are both a useful tool for use in the study of neuroendocrine control of pituitary hormone secretion and a valid pharmacologic weapon for treatment of hyperprolactinemic states, GH and, probably, ACTH and MSH hypersecretion.

The biogenesis of the ergot alkaloids
Experientia, 1953Es wird ein biogenetischer Weg vorgeschlagen, der zu Lysergsaure, dem gemeinsamen Teilstuck aller Mutterkornalkaloide, fuhrt. Der grundlegende Schritt der Biogenese besteht nach unserem Vorschlag in der Kondensation von Dihydro-Nikotinsaure (oder einem Derivat derselben) mit dem Chinon III, das aus 5-Oxytryptophan (oder einer gleichwertigen Verbindung)

Mycotoxin Research, 2009 As a contribution to the occurrence of ergot alkaloids in ergot from German rye and triticale, samples from the 2007 and 2008 harvests were analyzed. Twelve alkaloids—six pairs of main alkaloids and their corresponding epimers—were determined in extracts

Recent Investigations on Ergot Alkaloids
Chemical Reviews, 1950Ergot occupies a special position among the drugs of our therapeutic armamentarium, not only on account of its unusual classification in the vegetable kingdom but also because of its interesting biological characteristics and the remarkable nature of its active principles. Known botanically as Claviceps purpurea, ergot is a parasitic filamentous fungus

Bioconversions of ergot alkaloids
1991Ergot alkaloids are very important pharmaceutical substances with wide medical use. Their bioproduction is usually followed by chemical modification. Bioconversions of ergot alkaloids on an industrial scale have become more important in recent years.

Publisher Summary The production of the high yields of lysergic acid alkaloids by submerged cultures of Claviceps species has been achieved after some 40 years of effort. The first successful processes involved the production of simple lysergic acid derivatives, and these are now well established.

Abstract The ergot alkaloids can be divided into three groups: amino acid alkaloids, dihydrogenated amino acid alkaloids, and amine alkaloids. Ergotamine tartrate, a member of the amino acid group, is an ergopeptide consisting of a natural o-lysergic acid linked to a tricyclic moiety by a peptide bond.
