  Synthesis and biological evaluation of berberine–thiophenyl hybrids as multi-functional agents: Inhibition of acetylcholinesterase, butyrylcholinesterase, and Aβ aggregation and antioxidant activity

  摘要：

  A series of berberine-thiophenyl hybrids were designed, synthesised, and evaluated as inhibitors of acetylcholinesterase (AChE), butyrylcholinesterase (BuChE) and beta-amyloid (A beta) aggregation and as antioxidants. Among these hybrids, compounds 4f and 4i, berberine linked with o-methylthiophenyl and o-chlorothiophenyl by a 2-carbon spacer, were observed to be potent inhibitors of AChE, with IC50 values of 0.077 and 0.042 mu M, respectively. Of the tested compounds, 4i was also the most potent inhibitor of BuChE, with an IC50 value of 0.662 mu M. Kinetic studies and molecular modelling simulations of the AChE-inhibitor complex indicated that a mixed-competitive binding mode existed for these berberine. derivatives. The biological studies also demonstrated that these hybrids displayed interesting activities, including A beta aggregation inhibition and antioxidant properties. (C) 2013 Elsevier Ltd.
