Abstract:
The present invention relates to a silicon-substituted amino-pyronin compound derivative, a cell- or tissue-imaging method using the same, a cancer diagnosis method using the same, and a method for preparation of the same. More specifically, serving as a two-photon absorption fluorescent substance which has longer absorption and emission wavelengths in red or near-infrared regions of 625 nm or greater, compared to conventional one-photon absorption fluorescent substances, the silicon-substituted amino-pyronin compound derivative can minimize the influence of self-fluorescence in a bioimaging study and is thus expected to be suitable for high-resolution imaging in deep tissues. A fluorescent probe developed on the basis of the fluorescent substance platform is expected to find an expanded range of applications in analyzing and imaging specific materials in vivo.
Abstract:
A fluorescent probe compound, a preparation method thereof, and a method of imaging and quantifying lysosomal adenosine triphosphate (ATP) at a cell or tissue level through one-photon or two-photon fluorescence microscopy using the compound is disclosed. A fluorescence detection system capable of detecting lysosomal ATP is further disclosed. Since the fluorescent probe compound is found to be capable of selectively sensing and quantifying lysosomal ATP in a cell or tissue, it is expected that the disclosed compound or composition can be usefully employed in the study of various biological reactions or diseases associated with ATP in a living body.
