Fluorescent probe sensing tyrosine kinase and use thereof

Abstract

A fluorescent probe for detecting a tyrosine kinase using a compound having an ortho-hydroxy-benzaldehyde structure, and use thereof are provided. The fluorescent probe can show a change in fluorescence when the compound binds with a tyrosine kinase. The compound can be readily synthesized and has high stability and low cytotoxicity in vivo. The fluorescent probe can be used to image cells or tissues overexpressing the tyrosine kinase, the fluorescent probe can be effectively used in a composition for imaging the tissues and a method of imaging the tissues. Also, the fluorescent probe can be used to image cancer cells or tissues since the fluorescent probe can exhibit fluorescence when the fluorescent probe binds to the cancer cells or tissues overexpressing the tyrosine kinase.
