Gourni and co-workers reported succinic acid (DFO-Nsucc, Figure 10) and isothiocyanate (DFO-pNCS-Bn-NCS, Figure 10) derivatives of DFO and subsequent conjugation to PSMA for 68Ga preclinical imaging of prostate cancer in mice bearing subcutaneous LNCaP tumours [114]. This evidence concerns the gene FOLH1 and prostate cancer.
