Introduction to the Toxins Special Issue on Ergot Alkaloids

open access: yesToxins, 2015
Ergot alkaloids are among the most relevant natural products in the history of toxins and pharmaceuticals. Until the late 20th century, human and livestock exposure to ergot alkaloids was primarily through ingestion of “ergots,” which are spur-shaped or ...

Albert Hofmann's Pioneering Work on Ergot Alkaloids and Its Impact on the Search of Novel Drugs at Sandoz, a Predecessor Company of Novartis: Dedicated to Dr. Albert Hofmann on the occasion of his 100th birthday

open access: yesCHIMIA, 2006
The scientific research on ergot alkaloids is fundamentally related to the work of Dr. Albert Hofmann, who was able to produce, from 1935 onwards, a number of novel and valuable drugs, some of which are still in use today.

Plant-symbiotic fungi as chemical engineers: multi-genome analysis of the Clavicipitaceae reveals dynamics of alkaloid Loci [PDF]

open access: yes, 2013
The fungal family Clavicipitaceae includes plant symbionts and parasites that produce several psychoactive and bioprotective alkaloids. The family includes grass symbionts in the epichloae clade (Epichloë and Neotyphodium species), which are ...

Arterial Responses to Acute Low-Level Ergot Exposure in Hereford Cows

open access: yesFrontiers in Veterinary Science, 2018
Ergot alkaloids are toxic secondary metabolites produced by the fungus Claviceps purpurea that contaminate cereal grains. Current Canadian standards allow 2 to 3 parts per million of ergot alkaloids in animal feed.

BMC Microbiology / Rhodococcus erythropolis MTHt3 biotransforms ergopeptines to lysergic acid [PDF]

open access: yes, 2015
Background: Ergopeptines are a predominant class of ergot alkaloids produced by tall fescue grass endophyte Neotyphodium coenophialum or cereal pathogen Claviceps purpurea.

Genetics, Genomics and Evolution of Ergot Alkaloid Diversity

open access: yesToxins, 2015
The ergot alkaloid biosynthesis system has become an excellent model to study evolutionary diversification of specialized (secondary) metabolites. This is a very diverse class of alkaloids with various neurotropic activities, produced by fungi in several

Fungi - an Amalgam of Toxins and Antibiotics: a Mini- Review [PDF]

open access: yes, 2020
Fungi are eukaryotes with many functions. Earlier, fungi were classified in the plant kingdom but were later classified as a separate kingdom due to their unique cell walls. Fungi are heterotrophs like animals and are more closely related to animals. The

Relationships among Ergot Alkaloids, Cytochrome P450 Activity, and Beef Steer Growth

open access: yesFrontiers in Chemistry, 2015
Determining a grazing animal’s susceptibility to ergot alkaloids has been a research topic for decades. Our objective was to determine if the Promega™ P450-Glo assay could be used to indirectly detect ergot alkaloids or their metabolites in urine of ...

Mycotoxin occurrence in maize silage : a neglected risk for bovine gut health? [PDF]

open access: yes, 2019
Forages are important components of dairy cattle rations but might harbor a plethora of mycotoxins. Ruminants are considered to be less susceptible to the adverse health effects of mycotoxins, mainly because the ruminal microflora degrades certain ...
