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.
Carbonic anhydrase IX (CAIX) is a transmembrane protein involved in cell proliferation and transformation that is expressed in clear-cell renal cell carcinoma (ccRCC), colorectal cancer (CRC), and other hypoxic tumor types, but has low expression in healthy tissues.
Researchers at Merck & Co. Inc. have presented the discovery of novel selective metabotropic glutamate receptor 2 (mGluR2) negative allosteric modulators (NAMs) as potential PET imaging agents. Synthesis and optimization of a series of analogues of a potent and selective mGluR2 NAM resulted in the identification of compound MK-8056 as a high-affinity mGluR2 NAM (Ki=0.19 nM) with desirable lipophilicity (logD7.0=2.46) and low P-gp susceptibility.
In a study reported in the online edition of Science on Aug. 10, 2023, a group of synthetic biologists from the University of California (UC) San Diego and clinicians from Australia have engineered synthetic bacteria to detect specific DNA sequences in the genomes of colorectal cancer (CRC) cells and organoids. This living cell sensor capable of detecting cancer in the colons of mice has the potential to steer the way to new biosensors capable of identifying various infections, cancers and other diseases.
Fuzionaire Diagnostics Inc. has changed its name to Fuzionaire Theranostics Inc. to better reflect the company’s pipeline of paired fluorine-18 PET diagnostics and radioligand therapies to find and treat cancer.
Characterized by periods of deep and profound depression alternating with periods of excessive mania mood swings with diminished sleep, bipolar spectrum disorder (BSD) affected an estimated 40 million people globally in 2019 in the U.S. with a major part of the problem attributed to delays in diagnosis including a mean time of 5-13 years. These delays in BSD diagnosis exert lifelong impacts including heightened suicide risk, relationship strains, impaired work/education performance, significant financial burdens and increased risk for cardiovascular disease.
