A series of berberine-thiophenyl hybrids were designed, synthesised, and evaluated as inhibitors of acetylcholinesterase (AChE), butyrylcholinesterase (BuChE) and β-amyloid (Aβ) 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(More)
Recently, phosphodiesterase-9 (PDE9) inhibitors and biometal-chelators have received much attention as potential therapeutics for the treatment of Alzheimer's disease (AD). Here, we designed, synthesized, and evaluated a novel series of PDE9 inhibitors with the ability to chelate metal ions. The bioassay results showed that most of these molecules strongly(More)
A series of compounds with monoamine oxidase inhibition and biometal chelation activities were designed, synthesised and evaluated as agents against Alzheimer's disease. The in vitro assay shows that most target compounds exhibit good MAO-B activities with submicromolar IC50 values and antioxidant activity (1.49-5.67 ORAC-FL values). The selected compounds(More)
