Radiolabeling of peptides with fluorine-18 is hurdled by their chemical sensitivity and complicated processes. Original triflyl-pyridine intermediates afforded ammonium precursors that were radiolabeled at low temperature. From that study, a generic tag h

A compound of the formula STR1 wherein R1 is hydrogen or C1-6 -alkyl; R2 is C1-6 -alkyl or adamantyl; R3 is C1-6 -alkyl or hydroxy; or R2 and R3 taken together are --(CR6 R7)n --; R4 is C2-8 -alkyl, C2-8 -alkenyl, C2-8 -alkynyl, --OCH2 R5 or C2-8 -alkanoyl; and hydrogen when R3 is hydroxy; R5 is C1-6 -alkyl, C2-6 -alkenyl or C2-6 -alkynyl; R6 and R7 are hydrogen or C1-6 -alkyl; Y is oxygen or sulphur; and n is 3, 4 or 5, and pharmaceutically usable salts of carboxylic acids of formula I act as selective ligands of retinoic acid γ-receptors and are useful for the treatment of epithelial lesions.
