Title:
AMINO-SILA-PYRONIN COMPOUND-BASED ONE- OR TWO-PHOTON ABSORPTION FLUORESCENT SUBSTANCE AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2019/045522
Kind Code:
A1
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.
