New indodicarbocyanine dyes with the carboxybutyl group in position-3 of the indolenine fragment bearing methyl and sulfonic groups in positions 5 and 7 of the cycle were synthesized in order to find the most effective fluorescent labels for the biological microchip technology. The position of absorption and fluorescence maxima, the total charge of the dye molecule, and water solubility depend on the location and the total amount of methyl and sulfonic groups. The spectral characteristics of the dyes synthesized were determined. The relative fluorescence efficiencies of the dyes at equal concentrations were measured at excitation wavelengths of 635 and 655 nm and emission wavelengths of 670 and 690 nm, respectively.

applications of two series of fluorogenic probes based on cyanine 5 for identification of bacterial nitroreductase (NTR). The selected fluorogenic probe 3 generates a rapid 10-fold fluorescence response after being catalytically reduced by NTR to the intermediate para-aminobenzyl substituted which then underwent a rearrangement elimination reaction. Moreover, probe 3 is cell permeable for both Gram-positive
