A 13mer DNAduplex containing the artificial 4‐aminophthalimide:2,4‐diaminopyrimidine (4AP:DAP) base pair in the central position was characterized by optical and NMR spectroscopy. The fluorescence of 4AP in the duplex has a large Stokes shift of Δλ=124 nm and a quantum yield of ΦF=24 %. The NMR structure shows that two interstrand hydrogen bonds are formed and confirms the artificial base pairing

[MoH2(OMe)2(dppe)2] reacts with a series of phthalimide derivatives, each of which contains an electron-donor, an electron-acceptor, or redox-active center, to give the corresponding (substituted phthalimido)hydrido complexes in good yields. Investigation of spectroscopic properties suggests that some of these complexes have a polarized structure in a polar solvent.

A series of carbohydrate-dye conjugates, as well as a method for detection of pathogenic or other organisms (e.g., bacteria) using the same are provided. The carbohydrate-dye conjugate can be enzymatically incorporated into live and active (viable) bacteria of interest for facile detection of said bacteria. The conjugate incorporation is achieved by utilizing one or more of the enzymes that are endogenous to the bacteria of interest, which can incorporate the conjugate via the conjugate's carbohydrate. A detectable signal is produced by the conjugate's dye only upon incorporation into the bacteria of interest, due to the changes in the dye's local environment upon incorporation. The conjugate may be metabolically incorporated into the fatty outer membrane of a bacterial cell wall, which provides a distinctly hydrophobic environment for the conjugate's dye, causing it to produce a detectable signal.
The present invention provides fluorescent compounds of formula (I)
and methods monitoring protein-protein interactions.
