Ochratoxin A – 50th birthday
Ochratoxin A was discovered 1969 in South Africa, as a toxic metabolite of Aspergillus ochraceus from corn meal intentionally inoculated with said microfungus (Van der Merwe, 1965). Prompt after this first discovery, naturally occuring Ochratoxin A was isolated from a commercial corn sample in the USA (Shotwell et al., 1969). Also in 1969 (van Walbeek […]

Englerin A
Screening of plant extracts in search of new agents to treat cancer resulted in the discovery of Englerin A. A natural product, isolated from Phyllanthus engleri, shows potent selective cytotoxicity against renal cancer cells. But very little was known about its mechanism of action. Recently it was recovered that sesquiterpene (-)-englerin A was selectively killing renal […]

Ursolic acid
Ursolic acid is present in many plants but also fruits from daily life, like apples. It is known to be pro-apoptotic [1], suppresses tumor-invasion and has an anti-metastatic potential [2]. Besides its potential in being interesting for cancer research, it has an effect on muscle atrophy. Xu H. et al [3] found that Ursolic acid […]

Pyrrolizidine alkaloids
Pyrrolizidine alkaloids are secondary metabolites, produced by several plant species as protection against insect herbivores. They are common food contaminants in herbs, tea, salad, leafy vegetables and honey. Feed can be contaminated so that the plant products find their way in the food chain indirectly also over meat, milk and eggs. Pyrrolizidine alkaloids have adverse […]
