Researchers at Albert-Ludwigs-Universität Freiburg and Deutsches Krebsforschungszentrum (DKFZ) have disclosed drug conjugates comprising fluorescent-labeled dye covalently linked to a radionuclide and a ligand targeting glutamate carboxypeptidase II (NAALADase; NAAG peptidase, FOLH1; PSMA) acting as positron-emission tomography (PET) and fluorescent imaging agents for diagnosis and treatment of prostate cancer.
Fibroblast activation protein (FAP) is a serine protease that is highly overexpressed in the stroma of most epithelial-derived tumors – including pancreatic, breast and colorectal cancers – in the context of cancer-associated fibroblasts (CAFs).
Researchers at F. Hoffmann-La Roche Ltd. and Hoffmann-La Roche Inc. have synthesized radiolabeled compounds acting as GABA(A) receptor subunit α2β2γ1 (GABRA2) positive allosteric modulators acting as positron-emission tomography (PET) and autoradiography imaging agents reported to be useful for the diagnosis of neurological disorders.
Previous research has shown high expression of angiotensin-converting enzyme 1 (ACE1) in the triple-negative breast cancer (TNBC) cell line MDA-MB-231, suggesting the potential of ACE1 as a novel target for this disease. In the current study, researchers from Peking University Cancer Hospital presented the discovery of [68Ga]DOTA-BPP, a novel peptide nuclide molecular imaging probe targeting ACE1 for the imaging of TNBC.
Researchers from University Hospital Basel and Universitätsklinikum Ulm presented the discovery of novel radiotheragnostic candidates targeting C-X-C chemokine receptor 4 (CXCR4), which is highly expressed in various cancers and has been linked to poor prognosis.
Researchers from Huazhong University of Science and Technology presented the discovery and preclinical evaluation of a novel peptide PET tracer targeting LAG-3, [68Ga]NOTA-XH05, being developed as a candidate for evaluating the efficacy of cancer immunotherapy.
The discovery of new 68Ga-labeled CD38-targeted peptides for PET imaging was recently discussed by researchers from Peking University First Hospital and China National Center For Nanoscience & Technology.
Researchers from Peking University Cancer Hospital presented the discovery and preclinical evaluation of [124I]IMMU-132, a trophoblast cell surface antigen 2 (Trop2)-targeting molecular probe for micro-PET imaging.
Integrin alphavbeta3 and aminopeptidase N (CD13) are important biomarkers involved in tumor angiogenesis, tumor growth and metastasis. Peptides RGD (Arg-Gly-Asp) and NGR (Asn-Gly-Arg) are the most studied peptides for targeting integrin alphavbeta3 and CD13, respectively.
