    摘要: The present invention describes a family of photolabile caged nucleotides, including cyclic nucleotides. The compounds of the present invention are caged analogs and derivatives of NAD.sup.+, NADH, NADP, NADPH, NAADP and cADPR. The photolysis of the present compounds allows the release of the free nucleotide in vivo or in vitro with precise spatial and temporal control. The compounds are useful for the photolytic generation of free nucleotides in aqueous samples, for example, in the study of calcium mobilization in cells and cell homogenates.

    摘要: The invention describes crown ether chelators, including crown ethers having the formula and aza-substituted and thia-substituted analogs thereof. These crown ethers are substituted by a dye moiety, a chemically reactive group, a conjugated substance, or a combination thereof. Chelators that are substituted by fluorescent dyes are particularly useful as indicators for metal cations, particularly Na+ and K+ ions, and particularly where binding of the target ion results in a change in the fluorescence properties of the indicator that can be correlated with the ion concentration. Methods are provided for utilizing reactive groups on the chelators for conjugation to dyes, lipids and polymers and methods for enhancing entry of the indicators into living cells.

    摘要: The present invention comprises 6,8-difluoro-7-hydroxycoumarins and derivatives of 6,8-difluoro-7-hydroxycoumarins, including reactive dyes, dye-conjugates and enzyme substrates. These fluorine-substituted fluorescent dyes typically possess greater photostability and lower pH sensitivity in the physiological pH range than their nonfluorinated analogs, exhibit less fluorescence quenching when conjugated to a substance, possess absorption and emission spectra that closely match those of their nonfluorinated analogs, and also exhibit higher quantum yields than their nonfluorinated analogs.

    摘要: The invention describes the synthesis and use of photoactivated (or caged) fluorescent dyes. Upon illumination at less than about 400 nm the caged dyes release highly fluorescent, water soluble hydroxypyrenesulfonic acid dyes according to the following equation: ##STR1## X, Y, and Z are independently sulfonic acid, a sulfonic acid salt, a hydroxyl group, or hydrogen, with at least one of X, Y, and Z being a sulfonic acid or sulfonic acid salt. LINK is either an ether linkage or a carbonate linkage. BLOCK is a caging group whose photolysis results in liberation of a free hydroxypyrenesulfonic acid dye.The caged fluorescent dyes are useful for application in aqueous solutions, including fluids of biological origin. The caged dyes of the present invention are especially useful for flow tagging velocimetry.
