Abstract
- Alzheimer's disease (AD) is the most common cause of dementia and there is no cure for this disease. It is known that it is triggered by the apparition of the senile plaques produced for the agglomeration of β-amyloid peptides. AD´s reliable diagnosis is done post-mortem. Recently, non-invasive methods are evaluated for in vivo diagnosis of this disease by means of imaging techniques PET (Positron Emission Tomography), SPECT (Single Photon Emission Computed Tomography) and MRI (Magnetic Resonance Imaging). In the case of the SPECT technique, new organic compounds labeled with radionuclides 123I, 125I, and 99 mTc have been described. Epidemiological studies have revealed that the use of non-steroidal anti-inflammatory drugs decreases the relative risk of AD. In the last years, the search of compounds with similar structures it has increased in order to be used as labels or drugs. The objective of this paper was to synthesize new naphthalene derivatives, for its further use as quelating agents of 99 mTc, for the detection of β-amyloid plaque in the AD. Thus, spacer arms with different lengths were introduced at β-position (or 1-) of naphthalene molecule through various different reactions. The compounds were structurally characterized by IR, 1H-NMR and 13C- NMR spectroscopies and mass spectrometry. [ABSTRACT FROM AUTHOR]
