Abstract: Novel radiotracer for positron emission tomography (PET) or single photon emission computed tomography (SPECT) imaging are described. Specifically, the invention relates to 18F-labeled afatinib suitable as a PET or SPECT tracer for imaging epidermal growth factor receptor (EGFR, erbB1) and human epidermal growth factor receptor 2 (Her2, erbB2), to a precursor compound for use in its synthesis, to methods for the preparation 18F-labeled afatinib, as well as to the use thereof in in vivo diagnosis, tumor imaging or patient stratification on the basis of mutational status of EGFR (erbB1) and Her2 (erbB2).

Abstract: The invention is directed to a compound according to formula (1) wherein R2 is fluorine, X is nitrogen or carbon and R3 is an organic group. The invention is also directed to the use of this compound as a precursor for the preparation of a 11C or 18F-radio labelled compound. The radio labelled compound may be used in an in vivo diagnostic or imaging method.

Abstract: The invention is directed to a N,N-substituted guanidine compound or a salt or solvate thereof according to formula (1), R1RNC(NH)NR2R3, wherein R1 is methyl and R2 is hydrogen. R3 is a organic group comprising a halogen and thiomethyl substituted phenyl group. R is an organic group comprising a substituted aryl group Z wherein the substituent group is —Y—R4, wherein Y is a heteroatom chosen from the group consisting of O, S and N and R4 is a fluorinated organic group.

Abstract: The invention is directed to radiolabelled MMP selective compounds, a processes for the preparation thereof, and uses thereof. The derivatives of the invention have formula (I) wherein Y represents O, CH2, (CH2)2, S, NH, or C(?O)NH; X represents 1-5 substituents, wherein said substituents can be the same or different and wherein at least one of said substituents comprises a radioisotope suitable for PET and/or SPECT and/or a ?-emitter; Z is S; Q is chosen from the group consisting of 3-pyridyl and carboxyl; and R is chosen from the group consisting of C(?O)—NH—OH, (II), (III, (IV). The MMP selective compounds of the invention are selective for MMPs and can be used for the identification and treatment of unstable atherosclerotic plaques.
