LMU chemists design a route for synthesis of loline alkaloids LMU chemists led by Professor Dirk Trauner have developed a concise and efficient method for the synthesis of the alkaloid loline and related compounds. Loline alkaloids are a biologically interesting group of natural products, which have unusual physicochemical and pharmacological characteristics, but are as of yet poorly understood. They are produced by fungal symbionts that infect weeds and forage grasses, and act as deterrents...

HOUSTON, Aug. 29, 2005 "“ New research by biologists at Rice University, Indiana University and George Mason University reveals how some non-native fescue grass gets a leg up over competing native plants: it's passed over by plant-eating insects and animals because its leaves are laced with toxic alkaloids, thanks to a symbiotic fungus that has co-evolved with the grass. In a 54-month study conducted at Indiana University, scientists showed that 'tall fescue,' a common variety that is...
