Abstract
Synthesis and photophysical studies of (O-methyl)-β-tyrosine (β-tyrosine; an analogue of tyrosine, in which the amino group is moved from the α- to the β-carbon, closer to the phenol ring) and its derivatives with a blocked amino and/or carboxyl group were performed to explain the nature of the fluorescence of tyrosine derived analogues. All β-tyrosine derivatives, except Ac-βTyr(Me), displayed the monoexponential fluorescence decay. The biexponential fluorescence decay observed for Ac-βTyr(Me) is assumed to be the result of the presence of two low-energy conformations (extended and with an intramolecular hydrogen bond). Higher quenching of the fluorescence of β-tyrosine derivatives by the N-acetyl group than by the N-methylamide group moved farther was found, contrary to the data found for the respective derivatives of natural tyrosine. The obtained photophysical data are discussed with theoretical calculations (AMBER, AM1) on the basis of the rotamer model.
