Facile synthesis of a novel genetically encodable fluorescent α-amino acid emitting greenish blue light?
Chemical Communications Pub Date: 2020-09-11 DOI: 10.1039/D0CC03643A
Abstract
We report the facile synthesis and characterization of a novel fluorescent α-amino acid 4-phenanthracen-9-yl-L-phenylalanine (Phen-AA) (5) that emits greenish blue light in the visible region. This genetically encodable L-α-amino acid has excellent photostability with a 75% quantum yield. It readily gets into human cells, being clearly imaged upon 405 nm laser excitation. The synthetic procedure is resistant to racemization and only involves three simple steps which use mild conditions and generate the Phen-AA in reasonably good yield. It may find broad applications in research, biotechnology, and the pharmaceutical industry.
