The present invention provides a method for functionalization of an aromatic amino acid or a nucleobase with a fluoroalkyl-containing moiety RF, wherein the aromatic amino acid is reacted in the presence of at least one reductant with at least one hypervalent iodine fluoroalkyl reagent carrying said floroalkyl-containing moiety RF. The invention further provides novel hypervalent iodine fluoroalkyl reagents.

The invention relates to a process for producing a compound comprising the anion [CF2 18FSO2]-, which process comprises treating a difluorocarbene source with (i) a source of 18F- and (ii) a source of SO2. The invention relates to a compound which comprises that anion. The invention also relates to the use of the compound comprising the anion [CF2 18FSO2]- to produce a compound comprising an 18F-trifluoromethyl functionalised aromatic group. Compounds comprising an 18F-trifluoromethyl functionalised aromatic group are also the subject of the present invention.

The present invention provides novel receptor-binding cyclic peptides that advantageously display high receptor binding affinity and selectively. More particularly, the present invention provides integrin-binding cyclic peptides containing an integrin-binding motif such as an RGD motif, an aromatic amino acid such as a tyrosine residue, and a lysine residue having a pi-pi stacking moiety conjugated to its ε-amino group. Methods for identifying receptor-binding cyclic peptides and for using the cyclic peptides of the present invention for imaging a tumor, organ, or tissue and for treating cancer, inflammatory diseases, and autoimmune diseases are also provided.
