What is the amyloid hypothesis in Alzheimer's disease - Business Insider

Further synthesis of new benzimidazoles and in vitro screening against AD-PHFs is necessary to find improved drug candidates for in vivo testing. At this point, it is worth to mention that we also tested some quinoline derivatives that have some structural similarities with benzimidazoles, mainly their planar structure. Some of these quinolines also displayed high affinity for AD-PHFs. This fact led us to think that a perpendicular aromatic ring linked to a planar system, such as benzimidazole or quinoline, could be important for the binding to tau aggregates. Our search for AD tracers has been focused on the study of tau aggregates and small molecules that bind to tau fibrils because it has been demonstrated by several laboratories, including our own [,,], that future highly-specific methods for the diagnosis of AD should be developed based on the detection of NTFs and pre-tangle lesions in specific regions of the brain, mainly in the entorhinal cortex and hippocampus. As mentioned above, NFTs are the major pathological culprit for AD progression, and molecules that disassemble these anomalous aggregates could be used as efficient pharmacological agents to treat of this disease [].

Our finding that benzimidazole compounds with voluminous moities in position 2 display high affinity for tau aggregates () was a milestone in this research. Another important data is the positive correlation between NFTs propagation in brain and the clinical manifestations of AD []. This approach would allow clinical researchers to obtain maps of these brain lesions that are the major trademarks of this disease [,]. A new neuropathological classification for the topographical distribution of NFTs in the brain was proposed by these investigators. Nowadays it is difficult to develop innovative treatments for AD based on tau inhibitors, because it is not possible to monitor tau aggregation or formation of NFTs in the brain of AD patients. This limitation is also valid for the accurate diagnosis of AD, as it is not possible to differentiate AD from other type of dementias during the early stages of the disease, and for the establishment of preventive therapies as well. Amyloid deposits are also present in AD patients but without correlation with cognitive decline. An area of intense research is the development of radioligands for Aβ of potential use in PET tomography. Considering that PHFs rather than amyloid plaques are pathognomonics biomarkers for AD, we considered it biomedically relevant to investigate innovative approaches to tag NFTs in AD using the small molecules (

As we described in the experimental section, we worked with PHFs from tau protein isolated from brain of AD cases according to the protocol described in the methods section. PHFs were stained according to the protocol described by Santa-Maria et al. []. Then, we compared the staining patterns of benzimidazoles with the staining of thioflavine-S and PHF-1 immunostaining. Brains were obtained from autopsy cases of patients with clinical diagnosis of AD. We selected the tissues that were positive for at least two neuropathological criteria for AD diagnosis; the presence of i) amyloid plaques and ii) NFTs of tau protein. Final selection of the cases was done based on the reactivity to PHF-1 monoclonal antibody. The colocalization of the signals from LNS and PHF-1 mAb corroborates the affinity of LNS for AD-PHF. AST displayed very high affinity for tau, but is virtually non-fluorescent.
