The deoxyglucose dithiocarbamate (DGDTC) was radiolabeled with 99mTc(V)‐glucoheptonate (GH), for the potential use as radiopharmaceuticals for tumor imaging. For labeling, 99mTcO‐DGDTC was prepared by ligand‐exchange reaction with 99mTc‐GH. The radiochemical purity of the 99mTcO‐DGDTC complex was over 90% by thin‐layer chromatography and high‐performance liquid chromatography, without any notable decomposition at room temperature over a period of 6 h. Its partition coefficient indicated that it…

Synthesis and biodistribution of novel 99mTc labeled 4-nitroimidazole dithiocarbamate complexes as potential agents to target tumor hypoxia
TLDR
Among them, 99mTcO-N4IPDTC had the advantages of higher tumor uptake, and higher tumor/blood and tumor/muscle ratios.

Synthesis and biodistribution of novel 99mTcN complexes of glucose dithiocarbamate as potential probes for tumor imaging
TLDR
The single-photon emission computed tomography (SPECT) image studies of 99mTcN-3b showed obvious radioactive uptake in the tumor region and the tumor-to-non-target ratio was high, suggesting that it could be regarded as a promising tumor imaging agent.
Novel 99mTc labelled complexes with 2-nitroimidazole isocyanide: design, synthesis and evaluation as potential tumor hypoxia imaging agents.
TLDR
Among them, 99mTc-2c exhibited the highest tumor uptake, tumor/blood and tumor/muscle ratios at 2 h post-injection, and single photon emission computed tomography (SPECT) imaging studies indicated clear accumulation in tumors, suggesting that 99m Tc- 2c was a promising candidate for hypoxia imaging.
Synthesis and biological evaluation of novel 99mTc-oxo and 99mTc-nitrido complexes with phenylalanine dithiocarbamate for tumor imaging
TLDR
In this study, phenylalanine dithiocarbamate ligand was successfully synthesized and then radiolabeled with [99mTcO]3+ core and [99MTc≡N]2+ core to produce 99mT cO–PHEDTC and 99m TcN–PH EDTC, respectively, which showed they were hydrophilic and had good stability.
Synthesis and preliminary evaluation of a 99mTc labelled deoxyglucose complex {[99mTc]DTPA-bis(DG)} as a potential SPECT based probe for tumor imaging
