title: Design and synthesis of tacrine-ferulic acid hybrids as multi-potent anti-Alzheimer drug candidates.
abstract: Five tacrine-ferulic acid hybrids (6a-e) were designed and synthesized as multi-potent anti-Alzheimer drug candidates. All target compounds have better acetylcholinesterase inhibitory activity and comparable butyrylcholinesterase inhibitory activity in relation to tacrine. Interestingly, 6d showed a reversible and non-competitive inhibitory action for acetylcholinesterase indicating interaction with the peripheral anionic site, whereas a reversible but competitive inhibitory action for butyrylcholinesterase. The antioxidant study revealed that four target compounds have, compared to Trolox, high ability to absorb reactive oxygen species.
