The cyanobacterial L-BMAA (β-N-methylamino-L-alanine) is described as a low potency excitotoxin, possibly a factor in the increased incidence of amyotrophic lateral sclerosis (ALS) and Parkinsonism dementia complex (PDC) on Guam. The latter association is intensively disputed, as L-BMAA concentrations required for toxic effects exceed those assumed to occur via food. ...

This review confronts the classical view of plant immune defence and acclimation with recently published data. Earlier findings have linked plant immune defences to NB-LRR-dependent recognition of pathogen effectors and to the role of plasma membrane-localised NADPH-dependent oxidoreductase (AtRbohD), reactive oxygen species (ROS) and salicylic acid (SA). However, recent results ...

N-Vinyl nitrones derived from fluorenone have been prepared via a copper-mediated coupling between fluorenone oxime and vinyl boronic acids. These compounds undergo subsequent rearrangement and addition reactions that are distinct from the traditional [3 + 2] cycloaddition reactivity of nitrones. Thermal rearrangements of fluorenone N-vinyl nitrones give spiroisoxazolines, while treatment ...
