Abstract

Photophysics of constrained analogues of phenylalanine (Phe) modified at phenyl ring: tetrahydroisoquinoline-3-carboxylic acid (Tic), (5-methyl) tetrahydroisoquinoline-3-carboxylic acid ((5-Me)Tic), (2'-methyl)phenylalanine ((2/Me)Phe) and (2',6'-dimethyl)phenylalanine ((2',6'-Me-2) Phe) and their simple derivatives obtained by a modification of amino group (acetylation) or carboxylic group (amidation), or by both modifications at the same time was the subject of our investigations. The synthesized compounds were used to study the influence of (i) sterical constraints (cyclization or incorporation of methyl substituent(s) into phenyl ring), (ii) the N-acetylation ofthe amino group and (iii) the transformation of the carboxylic group into the amide on the photophysical properties of the phenylalanine analogue.
