Genetic Relationships in the Toxin-Producing Fungal Endophyte, Alternaria oxytropis Using Polyketide Synthase and Non-Ribosomal Peptide Synthase Genes

open access: yesJournal of Fungi, 2021
The legume Oxytropis sericea hosts a fungal endophyte, Alternaria oxytropis, which produces secondary metabolites (SM), including the toxin swainsonine.

Studies of an immunomodulator, swainsonine. I. Enhancement of immune response by swainsonine in vitro.

open access: yesThe Journal of Antibiotics, 1985
Swainsonine isolated from Metarhizium sp., was found to enhance the activities of the mouse immune system in vitro. Concanavalin A stimulated lymphocyte proliferation and proliferative response in mixed lymphocytes culture, which were suppressed by immunosuppressive factor obtained from serum of sarcoma 180 tumor bearing mouse, were restored to normal ...

A convenient approach to (-)-8-epi-swainsonine

open access: yes, 2006
A novel and efficient synthesis of (-)-8-epi-swainsonine (2) is reported. Face-selective diol formation from the bicyclic alkene 3 followed by a stereoselective vinylation of the aldehyde and ring-closing metathesis gave the indolizidine ring system ...

Increased intestinal permeability and lipopolysaccharide contribute to swainsonine-induced systemic inflammation

open access: yesEcotoxicology and Environmental Safety
Long-term consumption of swainsonine could be poisonous to livestock, including facilitating apoptosis by impairing lysosomal function and inhibiting autophagic degradation, leading to liver inflammation and even death in livestock.

Swainsonine: an inhibitor of glycoprotein processing. [PDF]

open access: yesProceedings of the National Academy of Sciences, 1981
Swainsonine, an indolizidine alkaloid, inhibits the processing of asparagine-linked glycoproteins in both cell-free extracts and animal cells in culture. Thus, in a liver particulate enzyme preparation, swainsonine at 0.1-1.0 microM inhibited the mannosidase that releases [3H]mannose from a high mannose glycopeptide but only slightly inhibited the ...

Analysis of carbohydrates and glycoconjugates by matrix‐assisted laser desorption/ionization mass spectrometry: An update for 2021–2022

open access: yesMass Spectrometry Reviews, Volume 44, Issue 3, Page 213-453, May/June 2025.
Abstract The use of matrix‐assisted laser desorption/ionization (MALDI) mass spectrometry for the analysis of carbohydrates and glycoconjugates is a well‐established technique and this review is the 12th update of the original article published in 1999 and brings coverage of the literature to the end of 2022.

A survey of swainsonine content in Swainsona species

open access: yes, 2017
The indolizidine alkaloid swainsonine is an inhibitor of α-mannosidase and mannosidase II that causes lysosomal storage disease and alters glycoprotein processing.

Potential Degradation of Swainsonine by Intracellular Enzymes of Arthrobacter sp. HW08

open access: yesToxins, 2013
Swainsonine (SW) is a toxin produced by locoweeds and harmful to the livestock industry. Degrading SW by Arthrobacter sp. HW08 was demonstrated as a promising way to deal with SW poisoning.
