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.
Eisai R&D Management Co. Ltd., National Institutes for Quantum and Radiological Science and Technology (QST), Ono Pharmaceutical Co. Ltd. and Takeda Pharmaceutical Co. Ltd. have patented new radiolabeled compounds targeting α-synuclein (α-Syn, SNCA) and acting as optical imaging agents for the diagnosis of Lewy body dementia (DLB), multiple system atrophy and Parkinson’s disease.
Bicycle radionuclide conjugates (BRCs) have been developed as a unique radiotheranostic modality for imaging and targeting of proteins overexpressed by tumors, and they possess favorable drug-like properties allowing for effective delivery of radioisotopes. Researchers from Bicycletx Ltd. recently presented a new BRC that targets ephrin type-A receptor 2 (EphA2), named BCY-18469.
Researchers at the University of Bonn and Westfälische Wilhelms-Universiteit Münster have prepared labeled compounds acting as 5’-nucleotidase (CD73) inhibitors.
