Compound, extracellular vesicle staining agent, and fluorescent staining method for extracellular vesicles

Abstract

An object is to provide a novel compound expressed by the following Formula (1) that conjugates with an extracellular vesicle. (in Formula (1), R1 represents H, a C1-C6 alkyl group, a hydroxy group, an amino group, or a carboxy group, R2 represents H, a C1-C18 alkyl group, a C1-C18 alkoxy group, NO2 or N(CH3)2, and R3 and R4 each independently represent H or CH3, where R3 and R4 may be bonded to each other to form a ring and, when R3 and R4 are bonded to each other to form a ring, R3 and R4 are CH2, “a” represents 0 or 1, and “b” represents 1, 2, or 3, and Z represents a linker in which 0 to 12 chain molecules formed of elements selected from a group consisting of C, O, and N are bonded, and the chain molecules may include a cyclic structure or a branched chain.)
