Abstract:

Some of the background to the biosynthesis, synthesis and uses of ergot alkaloids has been reviewed. A novel synthesis of the indole system has been used in an attempt to synthesise a derivative of the tricyclic Uhles ketone. A variation on this method has been carried out using 3-indole propionic acid as the starting material. The novel synthesis of the indole ring system has been developed into a synthesis of a 4-substituted indole. A number of literature methods for the synthesis of 4-substituted indoles have been investigated, and their usefulness in the laboratory assessed. A modified Rei

Abstract:

The negative impacts of ergot contamination of grain on the health of humans and animals were first documented during the fifth century AD. Although ergotism is now rare in humans, cleaning contaminated grain concentrates ergot bodies in screenings which are used as livestock feed. Ergot is found worldwide, with even low concentrations of alkaloids in the diet (<100 ppb total), reducing the growth efficiency of livestock. Extended periods of increased moisture and cold during flowering promote the development of ergot in cereal crops. Furthermore, the unpredictability of climate change may hav

Abstract:

Neotyphodium species, endophytic fungi associated with cool-season grasses, enhance host fitness and stress tolerance, but also produce biologically active alkaloids including ergot alkaloids associated with fescue toxicosis in grazing animals. One approach to reduce fescue toxicosis is to manipulate genes in the ergot alkaloid pathway. The gene, dmaW, encoding the first pathway-specific step in ergot alkaloid biosynthesis, was cloned previously from Claviceps spp. and its function was demonstrated by expression in yeast. Putative homologs have been cloned from Neotyphodium coenophialum (from

Sorghum (Sorghum bicolor [L.] Moench) is fifth among the major cereal crops in the world in terms of production area and total production.

One of these pathogens is Claviceps africana Frederickson Mantle & de Milliano, commonly known as ergot. As is the case with many sorghum diseases, the best long term approach to control ergot may be the use of genetic resistance. There is limited information about resistance to C. africana in sorghum,

Alkaloid toxicities negatively impact livestock health and production and are of serious economic concern to animal industries. To date, few strategies have been developed to evaluate alkaloid levels in feed or to counteract alkaloid toxicities.

Abstract:

The ergot alkaloids are an important subgroup of indole alkaloids as they show a wide range of biological activity. A synthesis of the ergot alkaloid skeleton was attempted from the amino acid tryptophan, the biosynthetic precursor: We anticipated that the C ring of the skeleton would be constructed by an intramolecular Friedel-Crafts type acylation of an aziridine onto the C-4 position of the indole ring. The more reactive C-2 position of the ring would be blocked due to the electron I acceptance and steric hindrance of a pivaloyl protecting group on the indole nitrogen. The amino acid was co

Abstract:

Clavicipitaceous fungal endophytes provide several ecological benefits to their hosts. Besides improving host’s growth characteristics, Neotyphodium coenophialum, the endophyte of tall fescue (Lolium arundinaceum), produces ergot alkaloids that have been proposed to be involved in fescue toxicosis. One approach to address the toxicosis problem is to genetically manipulate and modify N. coenophialum by knocking out a pair of homologous genes, (dmaW1 and dmaW2), encoding dimethylallyltryptophan synthase, the enzyme for the first and determinant step in ergot-alkaloid biosynthesis.

Ergot alkaloids present in endophyte-infected (E+) tall fescue are thought to be the causative agent of fescue toxicosis, a syndrome affecting cattle in the eastern United States.

Abstract:

Tall fescue is a widely grown, cool season grass prevalent in the eastern United States that is known for its resistance to abiotic and biotic stresses. A main reason for tall fescue's resistance to these stresses is attributed to the presence of a fungal endophyte. Unfortunately, this endophyte also adversely affects cattle production. Cows consuming the ergot alkaloids produced by these endophytes can exhibit decreased feed intake, growth performance, organ vasoconstriction, and increased rectal temperature.

Endophyte-infected (E+) tall fescue grass has been associated with fescue toxicosis, a costly syndrome characterized by poor cattle performance and health resulting in significant production losses.

A number of symptoms of fescue toxicosis can be related to vasoconstriction of bovine core, peripheral, and foregut vasculature.

So, a study was conducted using mesenteric vasculature collected from heifers shortly after slaughter.

Abstract:

Ergotalkaloide sind sekundäre Stoffwechselprodukte des parasitären Schlauchpilzes Claviceps purpurea der auf Getreide Mutterkörner (Sklerotien) bildet. In Sklerotien sind toxische Ergotalkaloide enthalten. Durch C. purpurea werden vorrangig sechs verschiedene Ergotalkaloid-Epimerenpaare gebildet, die toxischen C8-(R)-Epimere und die biologisch nicht relevanten C8-(S)-Epimere, die ineinander umgewandelt werden können. Das Ziel der Arbeit war es, die Epimerisierung der Ergotalkaloide während der Probenvorbereitung im Vergleich zu bisher bekannten Probenaufarbeitungsverfahren zu minimieren. Diese
