Researchers from Washington University in St. Louis and affiliated organizations have provided details on the discovery and preclinical evaluation of [64Cu]NODAGA-PEG4-SL-022-GGS, a novel small peptide imaging agent for evaluating CD38 expression.
Researchers from the University of North Carolina, Chapel Hill and affiliated organizations have reported the development and preclinical evaluation of [18F]F-ZW-cinacalcet, a novel PET agent targeting the calcium-sensing receptor (CaSR) for parathyroid imaging.
Researchers from Duke University presented the discovery and preclinical evaluation of [211At]YF-2, a next-generation prostate-specific membrane antigen (PSMA)-targeted radiopharmaceutical.
Actinium-226 (226Ac) has been previously proposed as a potential surrogate isotope for the development of 225Ac radiopharmaceuticals for targeted alpha therapy (TAT). The benefits of 226Ac include its theoretically superior therapeutic potency as well as a short half-life of its progeny, expected to minimize the toxicities. Researchers from TRIUMF, University of British Columbia and affiliated organizations recently reported the discovery of a novel matched 225/226Ac-radiopharmaceutical pair, [225Ac]crown-TATE and [226Ac]crown-TATE, and conducted studies aiming to compare the radiation dosimetry of these candidates.
Researchers from the Mayo Clinic have reported findings from the preclinical evaluation of a novel cardiac targeting peptide (CTP)-based radiotracer – [68Ga]NOTA-CTP – being developed as a myocardial perfusion imaging PET probe.
Researchers from the Chinese Academy of Medical Sciences and Peking Union Medical College reported on the development of a novel EDB-FN-targeted Gd-based contrast agent, named EDB-Gd-DOTA-Cy7, for imaging and treatment planning of pancreatic ductal adenocarcinoma (PDAC).
Researchers from Stanford University and affiliated organizations have provided details on the discovery and preclinical evaluation of [11C]MGX-10S, a novel PET tracer for GPR84, which is a G protein-coupled receptor (GPCR) expressed predominately on myeloid cells.
Monoacylglycerol lipase (MAGL) is a key regulator of the endocannabinoid system (ECS), which has a critical neuromodulatory involvement in numerous functional mechanisms in the CNS. Based on this, MAGL is considered a promising therapeutic target in neuroinflammation and neurodegeneration. Researchers from ETH Zürich and affiliated organizations have recently presented their work on (R)-[18F]YH-134, a novel reversible radiotracer for imaging MAGL in the brain.
Dopamine D3 receptors play a relevant role in the CNS modulating neurological activity, and its dysfunction is linked to disorders such as schizophrenia, drug abuse or Parkinson’s disease. There is a need for blood-brain barrier (BBB)-penetrant D3 receptor radiotracers with high brain uptake to be used for neurological and neuropsychiatric disease diagnosis.
Despite the success of CAR T-cell therapies for cancer immunotherapy, only a small percent of patients have a significant clinical response, and it is difficult to distinguish responders from nonresponders at an early stage with current imaging techniques.
