Title:
NEAR-INFRARED FLUORESCENT PROBE FOR DETECTION OF PEPTIDASE ACTIVITY
Document Type and Number:
WIPO Patent Application WO/2018/159631
Kind Code:
A1
Abstract:
[Problem] To provide a novel fluorescent probe that has superior tissue permeability and is capable of detecting the activity of peptidase highly expressed in cancer cells using a fluorescent response having a longer wavelength. [Solution] This fluorescent probe for detecting peptidase activity includes a compound represented by formula (I) or a salt thereof [in the formula: X represents Si(Ra)(Rb) (where Ra and Rb each independently represent a hydrogen atom or an alkyl group); Y represents a C0-C3 alkylene group, and the alkylene group may be substituted with a halogen atom or haloalkyl; R1 represents 1-4 substituents, which are the same or different from each other, and which are independently selected from the group consisting of a hydrogen atom, a cyano group, and optionally substituted alkyl group, carboxyl group, ester group, alkoxy group, amide group, and azide group; R2 forms, together with R3, a 5- to 8-membered heterocyclic structure containing a nitrogen atom and a carbon atom to which R2 and R3 are bound; R4 forms, together with R5, a 5- to 8-membered heterocyclic structure containing a nitrogen atom and a carbon atom to which R4 and R5 are bound; R6, R7, R8, and R9 each independently represent a hydrogen atom, a halogen atom, a hydroxyl group, an alkyl group, a sulfo group, a carboxyl group, an ester group, an amide group, or an azide group; and R10 represents an amino acid-derived acyl residue].
