Abstract
As the "molecule of the century", 2-deoxy-2-[18F]fluoro-d-glucose ([18F]FDG) is a radioactive 18F-labeled glucose derivative with a wide range of applications for positron emission tomography (PET) imaging. Single photon emission computed tomography (SPECT) imaging is widely used, but there is no clinical probe comparable to [18F]FDG. In our previous work, [99mTc]Tc-CN5DG and [99mTc]Tc-CN7DG were successfully developed and achieved high-quality SPECT images. However, they still have the disadvantage of low tumor uptake and/or high uptake by nontarget organs. To develop novel tumor imaging agents with high tumor uptake and excellent tumor/nontarget ratios, in this study, starting from d-glucosamine hydrochloride, four phenyl group-containing isonitrile ligands were designed, synthesized, and radiolabeled with 99mTc. All the complexes had high radiochemical purity and good hydrophilicity and stability. Biodistribution experiments showed that [99mTc]Tc-L4 (i.e., [99mTc]Tc-CNMBDG) had the highest tumor uptake and tumor/background ratios among the four probes. In SPECT imaging studies, the tumor detected by [99mTc]Tc-L4 was more clearly visible than that of [99mTc]Tc-CN7DG because of the inappreciable interference from abdominal uptake. Preliminary clinical studies of [99mTc]Tc-L4 have been conducted and successfully showed the lesion location in a patient with non-small-cell lung cancer. In summary, [99mTc]Tc-L4 is expected to be a promising tumor SPECT imaging agent.

Pharmaceuticals (Basel) 2023; 16:ph16040612. [PMID: 37111368 PMCID: PMC10144323 DOI: 10.3390/ph16040612] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/05/2023] [Revised: 04/06/2023] [Accepted: 04/14/2023] [Indexed: 04/29/2023] Open
Abstract
To develop novel tumor imaging agents with high tumor uptake and excellent tumor/non-target ratios, a glucose derivative containing cyclohexane (CNMCHDG) was synthesized and labeled with Tc-99m. [99mTc]Tc-CNMCHDG was prepared by a kit formulation that was straightforward to operate and fast. Without purification, [99mTc]Tc-CNMCHDG had a high radiochemical purity of over 95% and great in vitro stability and hydrophilicity (log P = -3.65 ± 0.10). In vitro cellular uptake studies showed that the uptake of [99mTc]Tc-CNMCHDG was significantly inhibited by pre-treatment with D-glucose and increased by pre-treatment with insulin. Preliminary cellular studies have demonstrated that the mechanism by which the complex enters into cells may be related to GLUTs. The results of biodistribution and SPECT imaging studies displayed high tumor uptake and good retention of [99mTc]Tc-CNMCHDG in A549 tumor-bearing mice (4.42 ± 0.36%ID/g at 120 min post-injection). Moreover, [99mTc]Tc-CNMCHDG exhibited excellent tumor-to-non-target ratios and a clean imaging background and is a potential candidate for clinical transformation.

Abstract
Radiopharmaceuticals are essential components of nuclear medicine and serve as one of the cornerstones of molecular imaging and precision medicine. They provide new means and approaches for early diagnosis and treatment of diseases. After decades of development and hard efforts, a relatively matured radiopharmaceutical production and management system has been established in China with high-quality facilities. This review provides an overview of the current status of radiopharmaceuticals on production and distribution, clinical application, and regulatory supervision and also describes some important advances in research and development and clinical translation of radiopharmaceuticals in the past 10 years. Moreover, some prospects of research and development of radiopharmaceuticals in the near future are discussed.
