NOVEL CELL PENETRATION TYPE FLUORESCENT DYE

摘要

PROBLEM TO BE SOLVED: To provide a fluorescent dye molecule capable of being applied as a skeleton of a cell introduction type probe corresponding to novel multicolor imaging, and to provide a synthesis method and a purification method.SOLUTION: There is provided a compound having 7-hydroxy quinoline skeleton represented by the formula (I), a derivative thereof or a salt thereof. In the formula (I), Ris H, a carbonyl group and the like, Ris null or Calkyl, alkylphenyl, Ris H, Calkyl, carbonyl, alkylcarbonyl or alkylamide, Xand Xare each independently selected from (C)alkyl, aryl(C)alkyl, (C)cycloalkyl, hetero(C)cycloalkyl, heteroaryl(C)alkyl, aryl and heteroaryl, which is each substituted or unsubstituted, n is 0 to 3 and m is 0 to 2.
