A novel indicator platform comprises a plurality of 1H-lndol-3-yl indicator compounds that are capable of converting to a signalophore compound in response to an external stimulus. In one class of indicator compounds, the resulting signalophores are 2-benzylideneindoline compounds that are formed by an intermolecular Aldol-type process; in a further class of indicator compounds, the resulting signalophores are 10H-indolo[1,2-a]indole compounds that are formed by an intramolecular Aldol-type process. The indicators can be used in a wide array of applications relating, for example, to biological systems or optical data storage.

Although isocyanides are not rare amongst terrestrial microbes and marine organisms, despite tens of thousands of natural products isolated from plants, isocyanides are still missing. Isocyalexin A is the firstisocyanide of plant origin. Isocyalexin A was isolated from UV-irradiated rutabaga roots and shown to be a new cruciferous phytoalexin. Its chemical structure was proven by analysis of NMR spectroscopic
