A sym-triazine with diverse biological activities
IC50: 0.3 ± 0.02 μM for AChE; 3.9 ± 0.2 μM for BuChE
TAE-1 is an inhibitor of amyloid-β fibril formation and aggregation.
Alzheimer’s disease (AD), a progressive neurodegenerative disorder, is characterized by the cerebral accumulation of insoluble aggregates of amyloid-β peptides (Aβ). Although the precise mechanisms governing neuronal loss remains ambiguous, toxicity resulting from Aβ-activated pathways is evident.
In vitro: In a previous study, the authors examined the effects of TAE-1 on differentiated human SH-SY5Y neuronal cells grown in tissue culture. Results showed that the stimulation of neuronal cellular process length and branching was noted. Moreover, the increased synaptophysin suggested that TAE-1 could stimulate synapse formation. Increased expression of MAP2 was also observed, indicating that TAE-1 promoted the differentiation of human neurons. In addition, targeted AChE inhibition was evaluated by electrochemical quantification of the enzymatic product, thiocholine, on unmodified gold screen-printed electrodes. It was found that at increasing TAE-1concentrations, there was a corresponding decrease in the AChE activity resulting in reduced amount of oxidizable thiocholine. The IC50 value was found to be 0.465 μM for TAE-1 [1].
In vivo: Up to now, there is no animla in vivo data reported.
Clinical trial: So far, no clinical study has been conducted.
