Abstract:
1. A biocompatible fluorescent molecule comprising one or more biomolecules covalently linked to a fluorescent compound represented by formula (2): or a salt thereof, wherein: X is independently selected from the group consisting of C(CH Y W represents a benzo-condensed ring or a naphtho-condensed ring; R R R Q is a heteroaryl ring substituted with —CO Q is selected from the group consisting of Q is a 6-membered heteroaryl ring substituted —C(═O)**, wherein R** is a saturated straight-chain hydrocarbon, a branched hydrocarbon, or a cyclic hydrocarbon; or Q is a carboxyl or carbonyl substituted 6-membered heteroaryl ring selected from the group consisting of pyridine, pyrimidone, pyrazine and pyridazine; and wherein the biomolecule becomes chemically linked to the compound via reaction with Q to produce the biocompatible fluorescent molecule.
