    摘要: 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.

    摘要: A novel type of dye systems comprises a selection of 10H-indolo[1,2-a]indole compounds (henceforth abbreviated as IO compounds) and (5H,7H)-indolo[1,2-a]quinoline compounds (henceforth abbreviated as IQ compounds) showing a solvatochromic effect and exhibiting strong fluorescence in a variety of materials such as polypropylene, polyethylene, oils, various solvents, emulsions. Also disclosed are various methods how the IO/IQ compounds can be administered, especially how they can be produced and administered in situ from a precursor, responding to external stimuli such as enzyme activity, temperature and so forth. The response of a precursor to external stimuli can also be used to determine the presence or absence of such stimuli.

    摘要: Plating media contains enzyme substrates (ES) used to detect enzyme activity associated with a target organism and that include a binding motif (BM) that serves to bind detectable enzymes (DE) (also called marker enzymes in this disclosure). A signalogenic substructure (SG) produces detectable signals and an enzyme labile group (ELG) is labile to the action of a marker enzyme and it typically includes the binding motif. The enzyme labile group links to the signalogenic substructure via a labile bond (LB) which is cleaved by the action of the marker enzyme separating the signalogenic substructure and the enzyme labile group. In some embodiments a linker is inserted between the signalogenic substructure and the enzyme labile group. Presence of the enzyme and thus the organism is detected by presence of a fluorogenic, precipitate that can be detected in single colonies.
