Abstract :
A novel series of tacrine-caffeic acid hybrids (5a-f) were designed and synthesized by combining caffeic acid (CA) with tacrine. The antioxidant study revealed that all the hybrids have much more antioxidant capacities compared to CA. Among these compounds, 5e showed the highest selectivity in inhibiting acetylcholinesterase (AChE) over butyrylcholinesterase (BuChE). Enzyme kinetic study had suggested that 5e binds to both catalytic (CAS) and peripheral anionic sites (PAS) of AChE. Moreover, compound 5e also inhibited self- or AChE-induced beta-amyloid(1-40) aggregation, as well as had potent neuroprotective effects against H(2)O(2)- and glutamate- induced cell death with low toxicity in HT22 cells. |
