The present invention relates to the compound of formula (I):
in which
R1 represents Sn(R)3, B(OH)2, B(OR)2, a halogen atom, NO2, a radionuclide or a -N+(R)3 group, where R is a (C1-C6) alkyl group,
R2 represents a hydrogen atom or a (C1-C6)alkyl group,
R3 represents:
- a -(CH2CH2O)n2-(CH2)n3-X group, or
- a ―(CH2CH2O)n4-(CH2)n5-Y group with Y representing a -C=C-H, a -N3 or a -Ar-(CH2)n6-(OCH2CH2)n7-X group, and
X represents a halogen atom, a radionuclide or a -OSO2R' group, where R' is a CF3, CH3, t-Bu, Ph, p-NO2Ph, p-BrPh or p-CH3Ph group,
and their addition salts with pharmaceutically acceptable acids,
The present invention also relates to pharmaceutical compositions comprising them and to their use in diagnosis, in particular with SPECT or PET imaging and in therapy of melanoma, via targeted radionuclide therapy.

to develop new iodinated and fluorinated matched-pair radiotracers for Single-Photon Emission Computed Tomography (SPECT)/Positron Emission Tomography (PET) imaging and targeted radionuclide therapy of melanoma, we successfully synthesized and radiolabelled with iodine-125 seven new derivatives, starting from our previously described lead structure 3. The relevance of these radiotracers for gamma scintigraphic
