The marine cyanobacteria have provided chemists and biologists with a plethora of natural products, with a wide array of structures and functional groups. 1, 2, 3 and 4 They have been a fertile source for new bioactive molecules, and many possess potent activity, across a broad spectrum of targets. Their diversity in both biological activity and in chemical complexity has made these secondary metabolites the focus of much work in recent years. We have had a great ...
