Abstract

Advances in the technetium chemistry have significantly enhanced the development of Tc-99m radiopharmaceuticals for clinical use. Efforts in designing novel Tc-99m labeled receptor or site-specific imaging agents using [TcvO]+3N2S2 core have produced useful imaging agents for single photo emission computed tomography (SPECT). The success in developing Tc-99m TRODAT-1 for CNS dopamine transporters (DAT) serves as the first example of Tc-99m site-specific imaging of human brain. New innovative Tc-99m labeled site-specific agents are particularly suitable to develop simple and useful routine diagnostic procedures.

      Biomedical imaging plays an significant role in both fundamental scientific researches and clinical theranostic applications [1–10]. Indeed, in the last few decades, the development of biomedical imaging technologies and corresponding contrast agents has resulted in a set of imaging methods in clinical practices, consisting of magnetic resonance imaging (MRI) [11–15], computed tomography (CT) [16–20], single-photo emission computed tomography (SPECT)[21–25] and positron emission tomography (PET) [26–30], allowing legible observation of physiological and pathological changes that deepen the understanding of life-threatening human diseases.Table 1. However, tomography imaging modes (including CT, PET and SPECT) have long suffered from low spatial resolution and involve the use of harmful ionizing radiations, preventing their uses in patients who are vulnerable to the effects of radiation, such as pregnant women and babies.

      We administered two executive function tests, the Wisconsin Card Sorting Test (WCST) and the Color Trails Test (CTT), a culturally fair analog of the Trail Making Test (Shan et al., 2008). Preparation of [99mTc] TRODAT-1 ([2-[[2-[[[3-(4-chlorophenyl)-8-methyl-8-azabicyclo[3,2,1]oct-2-yl]methyl](2-mercaptoethyl)amino]ethyl]amino]ethanethiolato(3-)-N2,N2′,S2,S2′]oxo-[1R-(exo-exo)]-(99m)Tc-technetium) was carried out as previously described (Kung, 2001), with minor modifications (Chou et al., 2007). In brief, it was prepared from a lyophilized kit by adding 1.110 MBq freshly eluted Tc-99-pertechnetate to a 5-ml saline preparation.

      Parkinson's disease is characterised by loss of dopamine neurons in the basal ganglia and substantia nigra. It has been estimated that in each month, about 100 scans using [99mTcVO(TRODAT-1)] are performed in Taiwan [100,101]. Attempts to provide technetium complexes suitable for diagnostic imaging of Aβ plaque burden have generally involved a bifunctional chelate approach, where ligands suitable for technetium are tethered to known plaque binding functional groups such as benzothiazoles and congo-red inspired derivatives.
