Work on indole, tryptophan, etc. continues because of their relevance to the complex field of protein photophysics. Creed has produced reviews of the photophysics and photochemistry of near-u.v.-absorbing amino-acids, viz. tryptophan and its simple derivatives, tyrosine and its simple derivatives, and cysteine and its simple derivatives. The nature of the fluorescent state of methylated indole derivatives has been examined in detail by Meech et al. Another investigation on indole derivatives deals particularly with solvent and temperature effects. Fluorescence quenching of indole by dimethylfor-mamide has also been examined in detail. Fluorescence excitation spectra of indoles and van der Waals complexes by supersonic jets give microscopic solvent shifts of electronic origin and prominent vibrational excitation of L(, states. Conventional flash photolysis of 1-methylindole in water shows R, e p, and a triplet state to be formed. " Changes in the steady-state fluores-... [Pg.33]

Recently, the [l8F]fluor<>bcnzaldehyde 5 was obtained by nucleophilic substitution of the 2-formyl-/V,/V,/V-trimcthylbenzcncammonium trifluoromethanesulfonate precursor 4 using nocarrier-added [K/222]I8F as the [laF]fluoride source. The ammonium trifluoromethanesulfonate 4 is obtained by quaternization of the dimethylamino compound 3.92 The [l8F]fluorobcnz-aldehyde 5 is used in the preparation of interesting radiopharmaceutical x-methyl-L-amino acids for positron emission tomography, as well as potential inhibitors of enzymatic functions.
