Development of Multifunctional Pyrimidinylthiourea Derivatives as Potential Anti-Alzheimer Agents
摘要:
Starting from a screening-hit compound, via structure modifications and optimizations, a series of nonfused and nonassembly pyrimidinylthiourea derivatives (2-5) was designed, synthesized, and evaluated as novel multifunctional agents against Alzheimer's disease. Biological activity results demonstrated that compounds 5r and 5t exhibited potent inhibition and excellent selectivity toward acetylcholinesterase (AChE, Sr, IC50 = 0.204 mu M, SI > 196; St, IC50 = 0.067 mu M, SI > 597), specific metal-chelating ability, significant antioxidant effects, modulation of metal-induced A beta aggregation, inhibition of ROS production by copper redox cycle, low cytotoxicity, and moderate neuroprotection to human neuroblastoma SH-SY5Y cells. Moreover, compound Sr displayed appropriate blood brain barrier (BBB) permeability both in vitro and in vivo and could improve memory and cognitive function of, scopolamine-induced amnesia mice. The multifunctional profiles of Sr and its effectivity in AD mice highlight these structurally distinct pyrimidinylthiourea derivatives as prospective prototypes in the research of innovative multifunctional drugs for Alzheimer's disease.
