Abstract: Disclosed are a compound with near-infrared fluorescence that selectively binds to tau aggregates, a method for preparing the same, a tau-targeting near-infrared fluorescent probe including the compound, a composition for detecting a tau fiber protein containing the near-infrared fluorescent probe as an active ingredient, and the use of the composition for the diagnosis of tauopathy. In particular, the compound does not bind to an amyloid beta protein and has high selectivity to a tau aggregate, specifically reported as an etiology of the initial state of tauopathy, thus being useful as a near-infrared fluorescent detector for detecting a tau fiber protein for early diagnosis of a tauopathy including Alzheimer's disease.

Abstract: Provided herein are a novel Zn-DPA complex compound and an siRNA delivery system including the same as a transporter, the Zn-DPA complex compound including: a phosphate-directing functional part of zinc (II)-dipicolylamine (“Zn-DPA”); a cell membrane-directing functional part; and a linker part that links the phosphate-directing functional part and the cell membrane-directing functional part. The Zn-DPA complex compound has low toxicity and efficiently delivers siRNA to cells, thereby useful in various ways for various studies and diagnosis and treatment of diseases, which use siRNA.
