Bactobolins are complex inhibitors of protein synthesis that target a novel site of the bacterial ribosome. A simple synthetic process by which (−)-quinic acid, L-threonine and L-alanine are combined to yield (+)-actinobolin is reported. The modularity of the approach unlocks new possibilities in analog synthesis.

negative photochromic compounds, donor-acceptor Stenhouse adducts (DASAs), is reported. Tailoring the electron deficient "acceptor" moiety yielded DASAs that can be activated with mild visible and far red light. The effect of acceptor composition on reactivity, absorption, equilibrium, and cyclability is exploited for the design of high performance photoswitches. The structural changes to the carbon acid

The invention relates to a substituted 4-trifluoromethyl carbostyril according to formula (I) and is characterised in that the 4-trifluoromethyl carbostyril is provided with an absorption maximum between 350 and 420 nm and a luminescence maximum between 430 and 900 nm. The molecule can be substituted with groups that are useful for complexing metal ions and/or for binding the molecule to relevant groups of a target molecule or a solid supporting material. The carbostyril as described above can inter alia serve as an antenna molecule of a lanthanide complex. Said complexes can be templates and can be brought into contact with a directly bound or free colour molecule which absorbs in the rant of 580-710 nm. Luminescence effects and decay periods can be measured after the contact with a relevant analyte.
